Hi Dr Sher,
I got covid during my ivf cycle last month, so had to cancel D9 after taking corifollitropan alfa D3.
I got my period early on D19 (usually have 28 day cycle) and my D2 E2 is 138 pg/ml. FSH (6) and progesterone (0.9).
My D2 E2 has always previously been <60.
Is the likely cause of high D2 E2 a functional cyst? I’m repeating bloods to see if E2 levels come down. Should I be getting an US?
Thanks!
Answer:
Yes! It is very often due to a folliclular cyst! It should absorb in time. Alternatively it can be aspirated under local, trans-vaginally and the level will drop….Good luck!

Hi, I have been a responding best to the long protocol where I start with Synarel on day 21. Because of low testosterone I’ve been taking DHEA for the last weeks. I read that DHEA can cause an increase in estrogen, while Synarel is suppose to decrease estrogen. Is it therefore a bad idea to continue with DHEA during down regulation? Should I stop as soon as I start down regulation or is it okay to continue DHEA during down regulation and stims? Thank you in advance for your input!
Answer:
Synarel is a GnRH agonist. It is administered nasally. As such, absorption sometimes erratic. I prefer Lupron or decapeptyl which are administered intramuscularly.
Dehydroepiandrosterone (DHEA), is steroid hormone produced by the adrenal glands and ovary. It is involved in producing the male hormones, androstenedione testosterone and also estrogen. DHEA blood levels tend to decline naturally with age.
Under the effect if luteinizing hormone (LH), DHEA is metabolized to testosterone in ovarian connective tissue (theca/stroma). Thereupon the testosterone is transported to the granulosa cells that form the innermost layer of the ovarian follicles where, under the influence of follicle stimulating hormone (FSH)-induced desmolase and aromatase enzymatic activity the testosterone is converted to estradiol. As this happens, granulosa cells multiply, follicle fluid volume increases along with estrogen output and egg development is promoted.
It is recognition of the essential/indispensable role that male hormones (mainly testosterone) play in follicle and egg development that prompted the belief that by giving DHEA and boosting ovarian testosterone production might benefit follicle/egg development. This belief was given some credence by an Israeli study that in 2010 reported on improved fertility when a group of infertile women were given the administration of 75mg of oral DHEA for 5 months. However, this study was seriously flawed by the fact that it did not separate out women who had diminished ovarian reserve, older women and those with PCOS, all of whom have increased LH-induced production of testosterone. In fact, we recently completed a study (currently being processed for publication) where we conclusively showed that when follicular fluid testosterone levels exceeded a certain threshold, egg quality was seriously prejudiced as evidenced by a marked increase in the incidence of egg chromosomal defects (aneuploidy).
Consider the following: Ovarian testosterone is needed for follicular development. However, the amount required is small. Too much ovarian testosterone spills over into the follicular fluid and has a deleterious effect on egg/follicle development. Some women (women with diminished ovarian reserve –DOR, older women and those with polycystic ovarian syndrome-PCOS) who tend to have increased LH biological activity, already over-produce testosterone. To such women, the administration of DHEA to such women, by “adding fuel to the fire” can be decidedly prejudicial, in my opinion. Young women with normal ovarian reserve do not over produce LH-induced ovarian testosterone, and are thus probably not at significant risk from DHEA supplementation. It is noteworthy that to date, none of the studies that suggest a benefit from DHEA therapy have differentiated between young healthy normal women with normal ovarian reserve on the one hand and older women, those with DOR and women with PCOS on the other hand.
In Some countries DHEA treatment requires a medical prescription and medical supervision. Not so in the U.S.A where it can be bought over the counter. Since DHEA is involved in sex hormone production, including testosterone and estrogen, individuals with malignant conditions that may be hormone dependent (certain types of breast cancer or testicular cancer) should not receive DHEA supplementation. Also, if overdosed with DHEA some “sensitive women” might so increase their blood concentrations of testosterone that they develop increased aggressive tendencies or male characteristics such as hirsuites (increased hair growth) and a deepening voice. DHEA can also interact other medications, such as barbiturates, corticosteroids, insulin and with other oral diabetic medications.
BUT the strongest argument against the use of routine DHEA supplementation is the potential risk of compromising egg quality in certain categories of women and since there is presently no convincing evidence of any benefit, why take the risk in using it on anyone.
Finally, for those who in spite of the above, still feel compelled to take DHEA, the best advice I can give is to consult their health care providers before starting the process.
Addendum: One potential advantage of DHEA therapy if used appropriately came from a study conducted by Washington University School of Medicine in St. Louis, MI and reported in the November 2004 issue of the “Journal of the American Medical Association” which showed that judicious (selective) administration of 50mg DHEA daily for 6 months resulted in a significant reduction of abdominal fat and blood insulin in elderly women.

Hi, very interesting article. I was using this hormone in my IVF treatment but I did not get results. It was administered one month before the egg retrieval and only for 30 days. Could this be the cause of it not working?
Thank 🙂
Answer:
No! You (in my opinion) do not need to take the HGH for long. My patients start a week before ovarian stimulation commences.

Dear dr. Shed,
I have 2 questions about my pregnancy. I have concerns about my Hcg levels which are rising higher than normal in 48h. At 4+2 weeks HCG is 2856. Is it normal? Are there any exact HCG result or signs of molar/extopic pregnancy?
The other question is for that we have concert ticket for openair stadium venue, but i have had 2 miscarriages before. Could be any risk for the baby if we attend it?
Thank you for your help.
Answer:
I don’t think attending a concert will prejudice your pregnancy!
Going through IVF is a major investment, emotionally, physically, and financially, for every patient or couple. One of the most crucial moments is receiving the result of the blood test for human chorionic gonadotropin (hCG) pregnancy. It’s a big deal! The days after the embryo transfer, waiting for this result, can be extremely stressful. That’s why it’s crucial for the IVF doctor and staff to handle this information with care and professionalism. They should be accessible to the patient/couple and provide results promptly and sensitively.
Testing urine or blood to check for human chorionic gonadotropin (hCG) is the best way to confirm pregnancy. Urine tests are cheaper and more commonly used. They are also more convenient because they can be done anywhere. However, blood tests are more reliable and sensitive than urine tests. They can detect pregnancy earlier and at lower hCG levels. Blood tests are also more accurate and can track changes in hCG levels over time. Urine tests can detect hCG when blood levels are above 20IU, which is about 16-18 days after ovulation or 2-3 days after a missed period. Blood tests can measure any concentration of hCG about 12-13 days after ovulation.
Detecting hCG in the blood early on and tracking its increase is especially useful for women undergoing fertility treatments like controlled ovarian stimulation or in vitro fertilization. The sooner hCG is detected and measured, the more information can be gathered about the success of implantation and the health of the developing embryo.
Typically, two beta hCG blood tests are done, spaced 2-4 days apart. It’s best to wait for the results of the second test before reporting on the pregnancy. This is because an initial result can change, even from equivocal or negative to positive. Sometimes a normal embryo takes longer to implant, and the hCG level can be initially low or undetectable. Regardless of the initial level, the test should be repeated after two days to check for a significant rise in hCG. A significant rise usually indicates that an embryo is implanting, which suggests a possible pregnancy. Waiting for the second test result helps avoid conveying false hope or disappointment.
It’s important to note that beta hCG levels don’t double every two days throughout pregnancy. Once the levels rise above 4,000U, they tend to increase more slowly. Except in specific cases like IVF using an egg donor or transfer of genetically tested embryos, the birth rate following IVF in younger women is around 40% per embryo transfer. Patients need to have realistic expectations and should be informed about how and when they will receive the news, as well as counseling in case of a negative outcome.
When an embryo starts to implant, it releases the pregnancy hormone hCG into the woman’s bloodstream. Around 12 days after egg retrieval, 9 days after a day 3 embryo transfer, or 7 days after a blastocyst transfer, a woman should have a quantitative beta hCG blood pregnancy test performed. By that time, most of the hCG injected to prepare the eggs for retrieval should have cleared from the bloodstream. So, if the test detects more than 10 IU of hCG per ml of blood, it indicates that the embryo has attempted to implant. In third-party IVF (e.g., ovum donation, gestational surrogacy, embryo adoption, or frozen embryo transfers), no hCG trigger is administered, so any amount of hCG detected in the blood is considered significant.
Sometimes, there is a slow initial rise in hCG between the first and second tests (failure to double every 48 hours). In such cases, a third and sometimes a fourth hCG test should be done at two-day intervals. A failure to double on the third and/or fourth test is a poor sign and could indicate a failed or dysfunctional implantation. In some cases, a progressively slow rising hCG level might indicate an ectopic pregnancy, which requires additional testing and follow-up.
In certain situations, the first beta hCG level starts high, drops with the second test, and then starts doubling again. This could suggest that initially, multiple embryos started to implant but only one survived to continue a healthy implantation.
It’s customary for the IVF clinic staff to inform the patient/couple and the referring physician about the hCG pregnancy test results. Often, the IVF physician or nurse-coordinator coordinates with the referring physician to arrange all necessary pregnancy tests. If the patient/couple prefer to make their own arrangements, the program should provide detailed instructions.
In some cases, when the two blood pregnancy tests show that one or more embryos are implanting, certain programs recommend daily injections of progesterone or the use of vaginal hormone suppositories for several weeks to support the implantation process. Others give hCG injections three times a week until the pregnancy can be confirmed by ultrasound examination. Some IVF programs don’t prescribe any hormones after the embryo transfer.
Patients with appropriate doubling of hCG levels within two days after frozen embryo transfer (FET) or third-party IVF procedures such as surrogacy or egg donation may receive estradiol and progesterone injections, often along with vaginal hormone suppositories, for 10 weeks after the implantation is diagnosed by blood pregnancy testing.
A positive Beta hCG blood pregnancy test indicates the possibility of conception, but ultrasound confirmation is needed to confirm the pregnancy. Until then, it is referred to as a “chemical pregnancy.” Only when ultrasound examination confirms the presence of a gestational sac, clinical examination establishes a viable pregnancy, or after abortion when products of conception are detected, is it called a clinical intrauterine pregnancy.
A significantly elevated hCG blood level without concomitant detection of an gestational sac inside the uterus by ultrasound after 5 weeks gestation raises the suspicion of an ectopic (tubal) pregnancy.
The risk of miscarriage gradually decreases once a viable clinical pregnancy is diagnosed (a conceptus with a regular heartbeat of 110-180 beats per minute). From this point onward, the risk of miscarriage is usually 10- 15% for women under 40 years old and around 35% for women in their early forties.
Dealing with successful IVF cases is relatively easy as everyone feels happy and validated. The real challenge lies in handling unsuccessful cases. Setting rational expectations from the beginning is crucial. In some cases (fortunately rare), emotional pressure may overwhelm the patient/couple, leading to a need for counseling or psychiatric therapy. I always advise my patients that receiving optimal care doesn’t always guarantee the desired outcome. There are many variables beyond our control, especially the unpredictable nature of fate. With around 36 years of experience in this field, I strongly believe that when it comes to IVF, the saying “man proposes while God disposes” always holds.
There are a few important things to consider when interpreting blood hCG levels. Levels can vary widely, ranging from 5mIU/ml to over 400mIU/ml, 10 days after ovulation or egg retrieval. The levels double every 48-72 hours until the 6th week of pregnancy, after which the doubling rate slows down to about 96 hours. By the end of the 1st trimester, hCG levels reach 13,000-290,000 IU and then slowly decline to around 26,000-300,000 IU at full term. Here are the average hCG levels during the first trimester:
- 3 weeks after the last menstrual period (LMP): 5-50 IU
- 4 weeks LMP: 5-426 IU
- 5 weeks LMP: 18-7,340 IU
- 6 weeks LMP: 1,080-56,500 IU
- 7-8 weeks LMP: 7,650-229,000 IU
- 9-12 weeks LMP: 25,700-288,000 IU
Most doctors wait until around the 7th week to perform an ultrasound to confirm pregnancy. By that time, the heartbeat should be clearly visible, providing a more reliable assessment of the pregnancy’s viability.
In some cases, blood hCG levels can be unusually high or increase faster than normal. This could indicate multiple pregnancies or a molar pregnancy. Rarely, conditions unrelated to pregnancy, such as certain ovarian tumors or cancers, can cause detectable hCG levels in both blood and urine.
To summarize, testing urine or blood for hCG is the most reliable way to confirm pregnancy. Urine tests are more common and convenient, while blood tests are more accurate and can detect pregnancy earlier. Tracking hCG levels in the blood is especially important for women undergoing fertility treatments. It’s essential to wait for the results of a second blood test before confirming pregnancy to avoid false hope or disappointment. Interpreting hCG levels requires considering various factors, and doctors usually perform an ultrasound around the 7th week for a more accurate assessment. Unusually high hCG levels may indicate multiple pregnancies or other conditions unrelated to pregnancy. Providing sensitive and timely communication of results is crucial for IVF clinics to support patients through the emotional journey.

Hi dear doctorI hope you are well ,why my All my three follicles was empty I used controlled ovarian stimulation thanks a lot
Answer:
Frequently, when following vigorous and often repeated flushing of follicles at egg retrieval they fail to yield eggs, it is ascribed to “Empty Follicle Syndrome.” This is a gross misnomer, because all follicles contain eggs. So why were no eggs retrieved from the follicles? Most likely it was because they would/could not yield the eggs they harbored.
This situation is most commonly seen in older women, women who have severely diminished ovarian reserve, and in women with polycystic ovarian syndrome (PCOS). In my opinion it is often preventable when an optimal, individualized and strategic protocol for controlled ovarian stimulation (COS) is employed and the correct timing and dosage is applied to the “hCG trigger shot.”
Normally, following optimal ovarian stimulation, the hCG “trigger shot” is given for the purpose of it triggering meiosis (reproductive division) that is intended to halve the number of chromosomes from 46 to 23 within 32-36 hours. The hCG trigger also enables the egg to signal the “cumulus cells” that bind it firmly to the inner wall of the follicle (through enzymatic activity), to loosen or disperse, so that the egg can detach and readily be captured at egg retrieval (ER).
Ordinarily, normal eggs (and even those with only one or two chromosomal irregularities) will readily detach and be captured with the very first attempt to empty a follicle. Eggs that have several chromosomal numerical abnormalities (i.e., are “complex aneuploid”) are often unable to facilitate this process. This explains why when the egg is complex aneuploid, its follicle will not yield an egg…and why, when it requires repeated flushing of a follicle to harvest an egg, it is highly suggestive of it being aneuploid and thus “incompetent” (i.e., incapable of subsequently propagating a normal embryo).
Older women, women with diminished ovarian reserve, and those with polycystic ovarian syndrome, tend to have more biologically active LH in circulation. LH causes production of male hormone (androgens, predominantly testosterone), by ovarian connective tissue (stroma/theca). A little testosterone is needed for optimal follicle development and for FSH-induced ovogenesis (egg development). Too much LH activity compromises the latter, and eggs so affected are far more likely to be aneuploid following meiosis.
Women with the above conditions have increased LH activity and are thus more likely to produce excessive ovarian testosterone. It follows that sustained, premature elevations in LH or premature luteinization (often referred to as a “premature LH surge”) will prejudice egg development. Such compromised eggs are much more likely to end up being complex aneuploid following the administration of the hCG trigger, leading to fruitless attempts at retrieval and the so called “empty follicle syndrome.”
The developing eggs of women who have increased LH activity (older women, women with diminished ovarian reserve, and those with PCOS) are inordinately vulnerable to the effects of protracted exposure to LH-induced ovarian testosterone. Because of this, the administration of medications that provoke further pituitary LH release (e.g., clomiphene and Letrozole), drugs that contain LH or hCG (e.g., Menopur), or protocols of ovarian stimulation that provoke increased exposure to the woman’s own pituitary LH (e.g., “flare-agonist protocols”) and the use of “late pituitary blockade” (antagonist) protocols can be prejudicial.
The importance of individualizing COS protocol selection, precision with regard to the dosage and type of hCG trigger used, and the timing of its administration in such cases cannot be overstated. The ideal dosage of urinary-derived hCG (hCG-u) such as Novarel, Pregnyl and Profasi is 10,000U. When recombinant DNA-derived hCG (hCG-r) such as Ovidrel is used, the optimal dosage is 500mcg. A lower dosage of hCG can, by compromising meiosis, increase the risk of egg aneuploidy, and thus of IVF outcome.
There is in my opinion no such condition as “Empty Follicle Syndrome.” All follicles contain eggs. Failure to access those eggs at ER can often be a result of the protocol used for controlled ovarian stimulation.

Dear Dr. Sher,
I recently underwent IVF, resulting in 2 complex aneuploid embryos – one with Trisomy 11 and 21 and the other with Monosomoy 15, 18, 19 and 22. No mitoscore values were reported. Is it worth considering transfer of these embryos?
I am 46 years old and despite my advanced age, I am hopeful that I can have a child with my own eggs and would like to undergo another round of IVF, however, I am afraid that the optimal protocol may not be selected by the fertility specialist. I would be most grateful if I can please get your advice on potential IVF protocols that might be best suited to me…..would you advise a Mini-IVF protocol? What would be the best way forward?
Thank you kindly in advance.
Best,
Vess
Answer:

Understanding the impact of age and ovarian reserve on the success of in vitro fertilization (IVF) is crucial when it comes to reproductive health. This article aims to simplify and clarify these concepts, emphasizing their significance in the selection of ovarian stimulation protocols for IVF. By providing you with this information, we hope to shed light on the importance of considering these factors and making informed decisions regarding fertility treatments.
- The Role of Eggs in Chromosomal Integrity: In the process of creating a healthy embryo, it is primarily the egg that determines the chromosomal integrity, which is crucial for the embryo’s competency. A competent egg possesses a normal karyotype, increasing the chances of developing into a healthy baby. It’s important to note that not all eggs are competent, and the incidence of irregular chromosome numbers (aneuploidy) increases with age.
- Meiosis and Fertilization: Following the initiation of the LH surge or the hCG trigger shot, the egg undergoes a process called meiosis, halving its chromosomes to 23. During this process, a structure called the polar body is expelled from the egg, while the remaining chromosomes are retained. The mature sperm, also undergoing meiosis, contributes 23 chromosomes. Fertilization occurs when these chromosomes combine, resulting in a euploid embryo with 46 chromosomes. Only euploid embryos are competent and capable of developing into healthy babies.
- The Significance of Embryo Ploidy: Embryo ploidy, referring to the numerical chromosomal integrity, is a critical factor in determining embryo competency. Aneuploid embryos, which have an irregular number of chromosomes, are often incompetent and unable to propagate healthy pregnancies. Failed nidation, miscarriages, and chromosomal birth defects can be linked to embryo ploidy issues. Both egg and sperm aneuploidy can contribute, but egg aneuploidy is usually the primary cause.
- Embryo Development and Competency: Embryos that develop too slowly or too quickly, have abnormal cell counts, contain debris or fragments, or fail to reach the blastocyst stage are often aneuploid and incompetent. Monitoring these developmental aspects can provide valuable insights into embryo competency.
- Diminished Ovarian Reserve (DOR): As women advance in their reproductive age, the number of remaining eggs in the ovaries decreases. Diminished ovarian reserve (DOR) occurs when the egg count falls below a certain threshold, making it more challenging to respond to fertility drugs effectively. This condition is often indicated by specific hormone levels, such as elevated FSH and decreased AMH. DOR can affect women over 40, but it can also occur in younger
Why IVF should be regarded as treatment of choice for older women an those who have diminished ovarian reserve ( DOR):
Understanding the following factors will go a long way in helping you to make an informed decision and thereby improve the chances of a successful IVF outcome.
- Age and Ovarian Reserve: Chronological age plays a vital role in determining the quality of eggs and embryos. As women age, there is an increased risk of aneuploidy (abnormal chromosome numbers) in eggs and embryos, leading to reduced competency. Additionally, women with declining ovarian reserve (DOR), regardless of their age, are more likely to have aneuploid eggs/embryos. Therefore, it is crucial to address age-related factors and ovarian reserve to enhance IVF success.
- Excessive Luteinizing Hormone (LH) and Testosterone Effects: In women with DOR, their ovaries and developing eggs are susceptible to the adverse effects of excessive LH, which stimulates the overproduction of male hormones like testosterone. While some testosterone promotes healthy follicle growth and egg development, an excess of testosterone has a negative impact. Therefore, in older women or those with DOR, ovarian stimulation protocols that down-regulate LH activity before starting gonadotropins are necessary to improve egg/embryo quality and IVF outcomes.
- Individualized Ovarian Stimulation Protocols: Although age is a significant factor in aneuploidy, it is possible to prevent further decline in egg/embryo competency by tailoring ovarian stimulation protocols. Here are my preferred protocols for women with relatively normal ovarian reserve:
- Conventional Long Pituitary Down Regulation Protocol:
- Begin birth control pills (BCP) early in the cycle for at least 10 days.
- Three days before stopping BCP, overlap with an agonist like Lupron for three days.
- Continue daily Lupron until menstruation begins.
- Conduct ultrasound and blood estradiol measurements to assess ovarian status.
- Administer FSH-dominant gonadotropin along with Menopur for stimulation.
- Monitor follicle development through ultrasound and blood estradiol measurements.
- Trigger egg maturation using hCG injection, followed by egg retrieval.
- Agonist/Antagonist Conversion Protocol (A/ACP):
- Similar to the conventional long down regulation protocol but replace the agonist with a GnRH antagonist from the onset of post-BCP menstruation until the trigger day.
- Consider adding supplementary human growth hormone (HGH) for women with DOR.
- Consider using “priming” with estrogen prior to gonadotropin administration
- Protocols to Avoid for Older Women or Those with DOR: Certain ovarian stimulation protocols may not be suitable for older women or those with declining ovarian reserve:
- Microdose agonist “flare” protocols
- High dosages of LH-containing fertility drugs such as Menopur
- Testosterone-based supplementation
- DHEA supplementation
- Clomiphene citrate or Letrozole
- Low-dosage hCG triggering or agonist triggering for women with DOR
Preimplantation Genetic Screening/Testing(PGS/T): PGS/T is a valuable tool for identifying chromosomal abnormalities in eggs and embryos. By selecting the most competent (euploid) embryos, PGS/T significantly improves the success of IVF, especially in older women or those with DOR.
Understanding the impact of advancing age and declining ovarian reserve on IVF outcomes is essential when making decisions about fertility treatments. Age-related factors can affect egg quality and increase the likelihood of aneuploid embryos with resultant IVF failure. Diminished ovarian reserve (DOR) further complicates the process. By considering these factors, you can make informed choices and work closely with fertility specialists to optimize your chances of success. Remember, knowledge is power, and being aware of these aspects empowers you to take control of your reproductive journey.

Hi Dr. Sher,
I am 41 years old and I am currently 8 weeks and 5 days pregnant through IVF and I need a second opinion when to stop Lovenox. Just to provide some background, I had two failed embryo transfers with AA euploid blastocysts. Then I was diagnosed with endometriosis and had excision surgery in March 2023. Also, I have these gene mutations:
PAI-1 (675 5G>4G) Homozygous
MTR (2756 A>G) Heterozygous
MTHFR (1298 A>C) Heterozygous
MTRR (66 A>G) Homozygous
I had test for homocysteine on 06/2023 – 5.8 umol/L
Test for PLASMINOGEN ACTIVATOR INHIBITOR 1 in 2021 – 5ng/ml
I am taking methylfolate form of folic acid.
Currently as part of IVF protocol besides progesterone/estrogen I am taking these medications since I had slightly elevated Th1/Th2 ratio and to reduce inflammation:
Prednisone 20mg/day
Tacrolimus 1mg/day
Lovenox 40
Aspirin 81
The doctor recommends stopping lovenox and tacrolimus at the end of week 9 and starting weaning down prednisone. I noticed that most people stop lovenox at the end of week 12 and want to ask what you would be recommendation. Also want to ask if there any pregnancy risks associated with gene mutations I have and do I need to do any specific bloodwork related to them?
Thank you,
Lena
Answer:
I would continue all the way through pregnancy and the 1st 6 weeks thereafter.
Thrombophilia (Hereditary Clotting Defect) is defined as the genetic predisposition to developing intravascular thrombosis. It is due to hypercoagulability of blood leading to impairment of initial vascularization that takes place during implantation.
Thrombophilia affects as many as one in five people in the United States and is responsible for pregnancy loss (most particularly after the 1st trimester) and “unexplained” infertility, as well as being a factor in some cases of “unexplained” IVF failure. Whether (and/or the extent to which) thrombophilia causes 1st trimester recurrent pregnancy loss (RPL) is the subject of debate and is controversial. In fact, first-trimester RPL is far more likely to be due to immunologic implantation dysfunction (IID) and/or irregularities in the contour of the uterine cavity or insufficient thickness of its lining (a thin endometrium). Thrombophilia has also been associated with late pregnancy-induced complications such as preeclampsia, premature separation of the placenta (abruptio placenta), placental insufficiency with intrauterine growth retardation, and in “unexplained” intrauterine death.
This having been said, it is a fact that most women with a thrombophilia go on to experience healthy pregnancies.
Diagnosis of Throbophilia
Thrombophilia is diagnosed when one or more of the following is detected:
- Mutational defect involving methylenetetrahydrofolate reductase (MTHFR), which occurs in at least 20% of affected cases. Homozygosity for a common C677T mutation in the MTHFR gene that is associated with hyperhomocysteinemia is the most common form of hereditary thrombophilia leading to a 3-fold increase in risk of complications.
- Mutation of factor V Leiden (FVL),
- A mutation of prothrombin G20210A,
- Deficiency of antithrombin III
- Deficiency of protein C
- Deficiency of protein S
Risk Factors
- Pregnant women with predisposing factors such as:
- A personal or family history of thromboembolism (deep vein thrombosis), pulmonary embolism (blood clot in the lung), cerebrovascular accidents (i.e. strokes)
- A personal history of pregnancy complications such as unexplained intrauterine death, preeclampsia, abruptio placenta, intrauterine growth retardation, placental insufficiency, should be tested for the condition.
Treatment
Treatment should be initiated as soon as possible after pregnancy is diagnosed biochemically (blood or urine hCG test) and be continued throughout gestation.
Severe thrombophilias (e.g. homozygous MTHFR mutations, protein C deficiency, prothrombin G20210A mutation) as well as cases of mild thrombophilias associated with one or more of the pregnancy complications mentioned above, are best treated with low-molecular weight heparin (LMWH) taken throughout pregnancy.
For other (milder) thrombophilias and no history of prior pregnancy complications: Low-dose aspirin with the B vitamins folic acid, B6 and B12.

Name: Timea H
Dear Dr. Sher,
I would like to ask about my hcg blood test results. It was not only doubled but fourfold in 48h. On Monday I had 220,9 nmol and 2 days later that was 996 nmol. Does it mean something wrong or not necessarily? Thank you for your help.
Answer:
No ! It looks good!
Going through IVF is a major investment, emotionally, physically, and financially, for every patient or couple. One of the most crucial moments is receiving the result of the blood test for human chorionic gonadotropin (hCG) pregnancy. It’s a big deal! The days after the embryo transfer, waiting for this result, can be extremely stressful. That’s why it’s crucial for the IVF doctor and staff to handle this information with care and professionalism. They should be accessible to the patient/couple and provide results promptly and sensitively.
Testing urine or blood to check for human chorionic gonadotropin (hCG) is the best way to confirm pregnancy. Urine tests are cheaper and more commonly used. They are also more convenient because they can be done anywhere. However, blood tests are more reliable and sensitive than urine tests. They can detect pregnancy earlier and at lower hCG levels. Blood tests are also more accurate and can track changes in hCG levels over time. Urine tests can detect hCG when blood levels are above 20IU, which is about 16-18 days after ovulation or 2-3 days after a missed period. Blood tests can measure any concentration of hCG about 12-13 days after ovulation.
Detecting hCG in the blood early on and tracking its increase is especially useful for women undergoing fertility treatments like controlled ovarian stimulation or in vitro fertilization. The sooner hCG is detected and measured, the more information can be gathered about the success of implantation and the health of the developing embryo.
Typically, two beta hCG blood tests are done, spaced 2-4 days apart. It’s best to wait for the results of the second test before reporting on the pregnancy. This is because an initial result can change, even from equivocal or negative to positive. Sometimes a normal embryo takes longer to implant, and the hCG level can be initially low or undetectable. Regardless of the initial level, the test should be repeated after two days to check for a significant rise in hCG. A significant rise usually indicates that an embryo is implanting, which suggests a possible pregnancy. Waiting for the second test result helps avoid conveying false hope or disappointment.
It’s important to note that beta hCG levels don’t double every two days throughout pregnancy. Once the levels rise above 4,000U, they tend to increase more slowly. Except in specific cases like IVF using an egg donor or transfer of genetically tested embryos, the birth rate following IVF in younger women is around 40% per embryo transfer. Patients need to have realistic expectations and should be informed about how and when they will receive the news, as well as counseling in case of a negative outcome.
When an embryo starts to implant, it releases the pregnancy hormone hCG into the woman’s bloodstream. Around 12 days after egg retrieval, 9 days after a day 3 embryo transfer, or 7 days after a blastocyst transfer, a woman should have a quantitative beta hCG blood pregnancy test performed. By that time, most of the hCG injected to prepare the eggs for retrieval should have cleared from the bloodstream. So, if the test detects more than 10 IU of hCG per ml of blood, it indicates that the embryo has attempted to implant. In third-party IVF (e.g., ovum donation, gestational surrogacy, embryo adoption, or frozen embryo transfers), no hCG trigger is administered, so any amount of hCG detected in the blood is considered significant.
Sometimes, there is a slow initial rise in hCG between the first and second tests (failure to double every 48 hours). In such cases, a third and sometimes a fourth hCG test should be done at two-day intervals. A failure to double on the third and/or fourth test is a poor sign and could indicate a failed or dysfunctional implantation. In some cases, a progressively slow rising hCG level might indicate an ectopic pregnancy, which requires additional testing and follow-up.
In certain situations, the first beta hCG level starts high, drops with the second test, and then starts doubling again. This could suggest that initially, multiple embryos started to implant but only one survived to continue a healthy implantation.
It’s customary for the IVF clinic staff to inform the patient/couple and the referring physician about the hCG pregnancy test results. Often, the IVF physician or nurse-coordinator coordinates with the referring physician to arrange all necessary pregnancy tests. If the patient/couple prefer to make their own arrangements, the program should provide detailed instructions.
In some cases, when the two blood pregnancy tests show that one or more embryos are implanting, certain programs recommend daily injections of progesterone or the use of vaginal hormone suppositories for several weeks to support the implantation process. Others give hCG injections three times a week until the pregnancy can be confirmed by ultrasound examination. Some IVF programs don’t prescribe any hormones after the embryo transfer.
Patients with appropriate doubling of hCG levels within two days after frozen embryo transfer (FET) or third-party IVF procedures such as surrogacy or egg donation may receive estradiol and progesterone injections, often along with vaginal hormone suppositories, for 10 weeks after the implantation is diagnosed by blood pregnancy testing.
A positive Beta hCG blood pregnancy test indicates the possibility of conception, but ultrasound confirmation is needed to confirm the pregnancy. Until then, it is referred to as a “chemical pregnancy.” Only when ultrasound examination confirms the presence of a gestational sac, clinical examination establishes a viable pregnancy, or after abortion when products of conception are detected, is it called a clinical intrauterine pregnancy.
A significantly elevated hCG blood level without concomitant detection of an gestational sac inside the uterus by ultrasound after 5 weeks gestation raises the suspicion of an ectopic (tubal) pregnancy.
The risk of miscarriage gradually decreases once a viable clinical pregnancy is diagnosed (a conceptus with a regular heartbeat of 110-180 beats per minute). From this point onward, the risk of miscarriage is usually 10- 15% for women under 40 years old and around 35% for women in their early forties.
Dealing with successful IVF cases is relatively easy as everyone feels happy and validated. The real challenge lies in handling unsuccessful cases. Setting rational expectations from the beginning is crucial. In some cases (fortunately rare), emotional pressure may overwhelm the patient/couple, leading to a need for counseling or psychiatric therapy. I always advise my patients that receiving optimal care doesn’t always guarantee the desired outcome. There are many variables beyond our control, especially the unpredictable nature of fate. With around 36 years of experience in this field, I strongly believe that when it comes to IVF, the saying “man proposes while God disposes” always holds.
There are a few important things to consider when interpreting blood hCG levels. Levels can vary widely, ranging from 5mIU/ml to over 400mIU/ml, 10 days after ovulation or egg retrieval. The levels double every 48-72 hours until the 6th week of pregnancy, after which the doubling rate slows down to about 96 hours. By the end of the 1st trimester, hCG levels reach 13,000-290,000 IU and then slowly decline to around 26,000-300,000 IU at full term. Here are the average hCG levels during the first trimester:
- 3 weeks after the last menstrual period (LMP): 5-50 IU
- 4 weeks LMP: 5-426 IU
- 5 weeks LMP: 18-7,340 IU
- 6 weeks LMP: 1,080-56,500 IU
- 7-8 weeks LMP: 7,650-229,000 IU
- 9-12 weeks LMP: 25,700-288,000 IU
Most doctors wait until around the 7th week to perform an ultrasound to confirm pregnancy. By that time, the heartbeat should be clearly visible, providing a more reliable assessment of the pregnancy’s viability.
In some cases, blood hCG levels can be unusually high or increase faster than normal. This could indicate multiple pregnancies or a molar pregnancy. Rarely, conditions unrelated to pregnancy, such as certain ovarian tumors or cancers, can cause detectable hCG levels in both blood and urine.
To summarize, testing urine or blood for hCG is the most reliable way to confirm pregnancy. Urine tests are more common and convenient, while blood tests are more accurate and can detect pregnancy earlier. Tracking hCG levels in the blood is especially important for women undergoing fertility treatments. It’s essential to wait for the results of a second blood test before confirming pregnancy to avoid false hope or disappointment. Interpreting hCG levels requires considering various factors, and doctors usually perform an ultrasound around the 7th week for a more accurate assessment. Unusually high hCG levels may indicate multiple pregnancies or other conditions unrelated to pregnancy. Providing sensitive and timely communication of results is crucial for IVF clinics to support patients through the emotional journey.

Dear Dr. Sher,
I would like to ask you, if there is any possibility to “prevent” a miscarriage, or help my body to deliver a baby overall.
Or any of your ideas just to help somehow.
I’m 29 and in the past I had 3 miscarriages (spontaneous pregnancies during 7-8 years) and 2 miscarriages (IVF – FET pregnancies during last 9 months). In all cases the embryo stopped developing at about 6-7 weeks.
In the last two pregnancies I took progesterone (200mg at the morning and 200mg in the evening) and estrofem (2mg at the morning and 2mg in the evening) and lastly acetylsalicylic acid (100mg in the evening). I also use active form of follic acid.
We already found out these problems from last few years and from blood testing: PCOS, obesity, hormonal imbalance, higher factor VIII (196%), positive ACLA IgG (41,4CU), limit value of a-annexin igG (5,0U/ml).
Now I’m pregnant again via FET (now I’m about 5+2) and I’m really not sure, if we can do anything else, to help except all above. At least from my point of view. This is our last possible embryo, so I’m trying my best in everything. Also a note, on husband’s side is everything without problem.
If you have any tip for another bloodworks, tests, what to look on, or just tips in general, it would be helpful.
Thank you in advance.
Answer:
When it comes to reproduction, humans face challenges compared to other mammals. A significant number of fertilized eggs in humans do not result in live births, with up to 75% failing to develop, and around 30% of pregnancies ending within the first 10 weeks (first trimester). Recurrent pregnancy loss (RPL) refers to two or more consecutive failed pregnancies, which is relatively rare, affecting less than 5% of women for two losses and only 1% for three or more losses. Understanding the causes of pregnancy loss and finding solutions is crucial for those affected. This article aims to explain the different types of pregnancy loss and shed light on potential causes.
Types of Pregnancy Loss: Pregnancy loss can occur at various stages, leading to different classifications:
- Early Pregnancy Loss: Also known as a miscarriage, this typically happens in the first trimester. Early pregnancy losses are usually sporadic, not recurring. In over 70% of cases, these losses are due to chromosomal abnormalities in the embryo, where there are more or fewer than the normal 46 chromosomes. Therefore, they are not likely to be repetitive.
- Late Pregnancy Loss: Late pregnancy losses occur after the first trimester (12th week) and are less common (1% of pregnancies). They often result from anatomical abnormalities in the uterus or cervix. Weakness in the cervix, known as cervical incompetence, is a frequent cause. Other factors include developmental abnormalities of the uterus, uterine fibroid tumors, intrauterine growth retardation, placental abruption, premature rupture of membranes, and premature labor.
Causes of Recurrent Pregnancy Loss (RPL): Recurrent pregnancy loss refers to multiple consecutive miscarriages. While chromosomal abnormalities are a leading cause of sporadic early pregnancy losses, RPL cases are mostly attributed to non-chromosomal factors. Some possible causes include:
- Uterine Environment Problems: Issues with the uterine environment can prevent a normal embryo from properly implanting and developing. These problems may include inadequate thickening of the uterine lining, irregularities in the uterine cavity (such as polyps, fibroid tumors, scarring, or adenomyosis), hormonal imbalances (progesterone deficiency or luteal phase defects), and deficient blood flow to the uterine lining.
- Immunologic Implantation Dysfunction (IID): IID is a significant cause of RPL, contributing to 75% of cases where chromosomally normal embryos fail to implant. It involves the immune system’s response to pregnancy, which can interfere with successful implantation.
- Blood Clotting Disorders: Thrombophilia, a hereditary clotting disorder, can disrupt the blood supply to the developing fetus, leading to pregnancy loss.
- Genetic and Structural Abnormalities: Genetic abnormalities are rare causes of RPL, while structural chromosomal abnormalities occur infrequently (1%). Unbalanced translocation, where part of one chromosome detaches and fuses with another, can lead to pregnancy loss. Studies also suggest that damaged sperm DNA can negatively impact fetal development and result in miscarriage.
IMMUNOLOGIC IMPLANTATION DYSFUNCTION AND RPL:
Autoimmune IID: Here an immunologic reaction is produced by the individual to his/her body’s own cellular components. The most common antibodies that form in such situations are APA and antithyroid antibodies (ATA). But it is only when specialized immune cells in the uterine lining, known as cytotoxic lymphocytes (CTL) and natural killer (NK) cells, become activated and start to release an excessive/disproportionate amount of TH-1 cytokines that attack the root system of the embryo, that implantation potential is jeopardized. Diagnosis of such activation requires highly specialized blood test for cytokine activity that can only be performed by a handful of reproductive immunology reference laboratories in the United States. Alloimmune IID, (i.e., where antibodies are formed against antigens derived from another member of the same species), is believed to be a common immunologic cause of recurrent pregnancy loss. Autoimmune IID is often genetically transmitted. Thus, it should not be surprising to learn that it is more likely to exist in women who have a family (or personal) history of primary autoimmune diseases such as lupus erythematosus (LE), scleroderma or autoimmune hypothyroidism (Hashimoto’s disease), autoimmune hyperthyroidism (Grave’s disease), rheumatoid arthritis, etc. Reactionary (secondary) autoimmunity can occur in conjunction with any medical condition associated with widespread tissue damage. One such gynecologic condition is endometriosis. Since autoimmune IID is usually associated with activated NK and T-cells from the outset, it usually results in such very early destruction of the embryo’s root system that the patient does not even recognize that she is pregnant. Accordingly, the condition usually presents as “unexplained infertility” or “unexplained IVF failure” rather than as a miscarriage. Alloimmune IID, on the other hand, usually starts off presenting as unexplained miscarriages (often manifesting as RPL). Over time as NK/T cell activation builds and eventually becomes permanently established the patient often goes from RPL to “infertility” due to failed implantation. RPL is more commonly the consequence of alloimmune rather than autoimmune implantation dysfunction. However, regardless, of whether miscarriage is due to autoimmune or alloimmune implantation dysfunction the final blow to the pregnancy is the result of activated natural killer cells (NKa) and cytotoxic lymphocytes (CTL B) in the uterine lining that damage the developing embryo’s “root system” (trophoblast) so that it can no longer sustain the growing conceptus. This having been said, it is important to note that autoimmune IID is readily amenable to reversal through timely, appropriately administered, selective immunotherapy, and alloimmune IID is not. It is much more difficult to treat successfully, even with the use of immunotherapy. In fact, in some cases the only solution will be to revert to selective immunotherapy plus using donor sperm (provided there is no “match” between the donor’s DQa profile and that of the female recipient) or alternatively to resort to gestational surrogacy.
DIAGNOSING THE CAUSE OF RPL.
In the past, women who miscarried were not evaluated thoroughly until they had lost several pregnancies in a row. This was because sporadic miscarriages are most commonly the result of embryo numerical chromosomal irregularities (aneuploidy) and thus not treatable. However, a consecutive series of miscarriages points to a repetitive cause that is non-chromosomal and is potentially remediable. Since RPL is most commonly due to a uterine pathology or immunologic causes that are potentially treatable, it follows that early chromosomal evaluation of products of conception could point to a potentially treatable situation. Thus, I strongly recommend that such testing be done in most cases of miscarriage. Doing so will avoid a great deal of unnecessary heartache for many patients. Establishing the correct diagnosis is the first step toward determining effective treatment for couples with RPL. It results from a problem within the pregnancy itself or within the uterine environment where the pregnancy implants and grows. Diagnostic tests useful in identifying individuals at greater risk for a problem within the pregnancy itself include Karyotyping (chromosome analysis) both prospective parents Assessment of the karyotype of products of conception derived from previous miscarriage specimens Ultrasound examination of the uterine cavity after sterile water is injected or sonohysterogram, fluid ultrasound, etc.) Hysterosalpingogram (dye X-ray test) Hysteroscopic evaluation of the uterine cavity Full hormonal evaluation (estrogen, progesterone, adrenal steroid hormones, thyroid hormones, FSH/LH, etc.) Immunologic testing to include Antiphospholipid antibody (APA) panel Antinuclear antibody (ANA) panel Antithyroid antibody panel (i.e., antithyroglobulin and antimicrosomal antibodies) Reproductive immunophenotype Natural killer cell activity (NKa) assay (i.e., K562 target cell test) Alloimmune testing of both the male and female partners
TREATMENT OF RPL
- Treatment for Anatomic Abnormalities of the Uterus:
This involves restoration through removal of local lesions such as fibroids, scar tissue, and endometrial polyps or timely insertion of a cervical cerclage (a stitch placed around the neck of the weakened cervix) or the excision of a uterine septum when indicated. Treatment of Thin Uterine Lining: A thin uterine lining has been shown to correlate with compromised pregnancy outcome. Often this will be associated with reduced blood flow to the endometrium. Such decreased blood flow to the uterus can be improved through treatment with sildenafil and possibly aspirin. sildenafil (Viagra) Therapy. Viagra has been used successfully to increase uterine blood flow. However, to be effective it must be administered starting as soon as the period stops up until the day of ovulation and it must be administered vaginally (not orally). Viagra in the form of vaginal suppositories given in the dosage of 25 mg four times a day has been shown to increase uterine blood flow as well as thickness of the uterine lining. To date, we have seen significant improvement of the thickness of the uterine lining in about 70% of women treated. Successful pregnancy resulted in 42% of women who responded to the Viagra. It should be remembered that most of these women had previously experienced repeated IVF failures. Use of Aspirin: This is an anti-prostaglandin that improves blood flow to the endometrium. It is administered at a dosage of 81 mg orally, daily from the beginning of the cycle until ovulation.
Treating Immunologic Implantation Dysfunction with Selective Immunotherapy:
Modalities such as intralipid (IL), intravenous immunoglobulin-G (IVIG), heparinoids (Lovenox/Clexane), and corticosteroids (dexamethasone, prednisone, prednisolone) can be used in select cases depending on autoimmune or alloimmune dysfunction. The Use of IVF in the Treatment of RPL In the following circumstances, IVF is the preferred option: When in addition to a history of RPL, another standard indication for IVF (e.g., tubal factor, endometriosis, and male factor infertility) is superimposed and in cases where selective immunotherapy is needed to treat an immunologic implantation dysfunction. The reason for IVF being a preferred approach when immunotherapy is indicated is that in order to be effective, immunotherapy needs to be initiated well before spontaneous or induced ovulation. Given the fact that the anticipated birthrate per cycle of COS with or without IUI is at best about 15%, it follows that short of IVF, to have even a reasonable chance of a live birth, most women with immunologic causes of RPL would need to undergo immunotherapy repeatedly, over consecutive cycles. Conversely, with IVF, the chance of a successful outcome in a single cycle of treatment is several times greater and, because of the attenuated and concentrated time period required for treatment, IVF is far safer and thus represents a more practicable alternative Since embryo aneuploidy is a common cause of miscarriage, the use of preimplantation genetic screening/ testing (PGS/T), with tests such as next generation gene sequencing (NGS), can provide a valuable diagnostic and therapeutic advantage in cases of RPL. PGS/T requires IVF to provide access to embryos for testing. There are a few cases of intractable alloimmune dysfunction due to absolute DQ alpha gene matching ( where there is a complete genotyping match between the male and female partners) where Gestational Surrogacy or use of donor sperm could represent the only viable recourse, other than abandoning treatment altogether and/or resorting to adoption. Other non-immunologic factors such as an intractably thin uterine lining or severe uterine pathology might also warrant that last resort consideration be given to gestational surrogacy. Conclusion:
Understanding the causes of pregnancy loss is crucial for individuals experiencing recurrent miscarriages. While chromosomal abnormalities are a common cause of sporadic early pregnancy losses, other factors such as uterine environment problems, immunologic implantation dysfunction, blood clotting disorders, and genetic or structural abnormalities can contribute to recurrent losses. By identifying the underlying cause, healthcare professionals can provide appropriate interventions and support to improve the chances of a successful pregnancy. The good news is that if a couple with RPL is open to all of the diagnostic and treatment options referred to above, a live birthrate of 70%–80% is ultimately achievable.

Dear Dr. Sehr, I’m almost 37 years old AMH 1,08 (measured under the pill, last measurement 09/21 was 3,5)
Husband has OAT3, used zymot last Icsi.
Had 4 ICSIs, 7 transfers, one MMC 9weeks, one MC six weeks. Last four transfers we had no success at all.
Used short protocol all the time:
1. icsi – 12 retrieved, 9 mature, 5 fertilised, 3 blasts (3aa/3BB/3bc)
PID not possible in Germany
3BB was MMC, 3BC was MC
Stims: Meriofert
2. ICSI – 9 retrieved, 7 mature, 5 fertilised, 2 blasts (early blast/2BB)
Stims: Pergoveris 225 IE – no success
3. ICSI – 12 retrieved, 7 mature, 5 fertilised, 2 blasts (3aa/ 3BB) – no success – Stims Pergoveris 300 IE
4. ICSI ( in Czech republic) – 8 retrieved, 5 mature, 3 fertilised, 2 Blasts (2x5bb) – Stims: Pergoveris 300, double trigger Decapeptyl 0.2+ 5000IE Hcg
Clinic says no PGT-A possible since they only tests AA. Devastated since we changed to Czech Republic for PID. Got them frozen but hopeless now.
We are trying for ten years now. I’m so sad. We live in Germany where everything useful is forbidden by the government.
Do you please have an advice?
Thank you so much in advance!!!
Answer:
I very respectfully disagree with your RE who informed you that only the best morphologic embryos should be biopsied. I also disagree with the use of “flare” (short)-DR protocols for women with diminished ovarian reserve (DOR).
The journey of in vitro fertilization can be a rollercoaster of emotions for many patients. Often times they have to face the harsh reality that the number and quality of eggs retrieved has fallen short of their expectations. Then, should fertilization of these eggs not propagate chromosomally normal (euploid), “competent” embryos suitable for transfer to the uterus, many such patients find themselves in a state of emotional distress. They grapple with the inevitable questions of why this happened and how to prevent it from occurring again in the future. This article aims to delve into these queries, providing insights, rational explanations, and therapeutic options. It is an invitation to explore the light at the end of the tunnel. Readers are urged to carefully absorb the entirety of the article in the hope of finding valuable information and renewed hope.
- The Importance of Chromosomal Integrity: While sperm quality is an important factor, egg quality is by far the most important when it comes to the generation of embryos that are capable of propagating healthy babies (“competent”). In this regard, chromosomal integrity of the egg and embryo, although it is not the only factor , is certainly the main determinant of such competency.
- The woman’s age: About two thirds of a woman’s eggs in her twenties or early thirties have the correct number of chromosomes, which is necessary for a healthy pregnancy. As a woman gets older, the percentage of eggs with the right number of chromosomes decreases. By age 40, only about one in every 5-6 eggs is likely to be normal, and by the mid-forties, less than one in ten eggs will be normal.
- Ovarian Reserve (number of available in the ovaries): A woman is born with all the eggs she will ever have. She starts using these eggs when she begins ovulating during puberty. At first, the eggs are used up quickly, but as she gets older, the number of eggs starts to run out. Her brain and pituitary gland try to stimulate the production of more eggs by increasing the output of Follicle Stimulating Hormone (FSH), but unfortunately, this often doesn’t work. When the number of remaining eggs in her ovaries falls below a certain level (which can be different for each woman), her FSH level rises, and production of the ovarian hormone, AMH decreases. This is the start of diminishing ovarian reserve (DOR). Most women experience the onset of DOR in their late 30s or early 40s, but it can happen earlier for some. The lower the ovarian reserve, the lower the AMH level will be, and the fewer eggs will be available for harvesting during IVF-egg retrieval. In such cases, a higher dosage of fertility drugs might be needed to promote better egg production in future attempts. . On the other hand, higher AMH levels mean more eggs are available, and lower doses of fertility drugs are usually needed. DOR is commonly associated with increased bioactivity of pituitary gland-produced LH. This LH activates production of ovarian male hormones (androgens)…predominantly testosterone by ovarian connective tissue (stroma) . While a small amount of ovarian testosterone is absolutely necessary for optimal follicle and egg development, excessive ovarian testosterone will often access the follicle , and compromise both egg quality and follicle growth and development. In some cases, rapidly increasing LH-release (“premature LH-surge”) with excessive induced ovarian testosterone can lead to “premature luteinization” of the follicles with cessation in growth and even to“ premature ovulation”.
- Importance of Individualized Controlled Ovarian Stimulation (COS) Protocol: It’s not surprising that DOR is more common in older women, but regardless of age, having DOR makes a woman’s eggs more likely to be compromised during controlled ovarian stimulation (COS). The choice of the COS protocol is crucial to preventing unintentional harm to egg and embryo quality. The wrong protocol can disrupt normal egg development and increase the risk of abnormal embryos. That’s why it’s important to tailor the COS protocol to each individual’s needs. This helps optimize follicle growth and the quality of eggs and embryos. The timing of certain treatments is also important for successful outcomes.
- Embryo Competency and Blastocyst Development: Embryos that don’t develop into blastocysts by day 6 after fertilization are usually chromosomally abnormal or aneuploid (”incompetent”) and not suitable for transfer. However, not all blastocysts are guaranteed to be normal and capable of developing into a healthy baby. As a woman gets older, the chances of a her embryos being chromosomally normal blastocyst decreases. For example, a blastocyst from a 30-year-old woman is more likely to be normal compared to one from a 40-year-old woman.
The IVF stimulation protocol has a big impact on the quality of eggs and embryos especially in women with DOR. Unfortunately, many IVF doctors use the same COS “recipe approach” for everyone without considering individual differences. Using personalized protocols can greatly improve the success of IVF. While we can’t change genetics or reverse a woman’s age, a skilled IVF specialist can customize the COS protocol to meet each patient’s specific needs.
GONADOTROPIN RELEASING HORMONE AGONISTS (GNRHA) AND GNRH-ANTAGONISTS:
- Gonadotropin releasing hormone agonists (GnRHa). Examples are Lupron, Buserelin, Superfact, and Decapeptyl . These are commonly used to launch ovarian stimulation cycles. They work by initially causing a release of pituitary gonadotropins, followed by a decrease in LH and FSH levels within 4-7 days. This creates a relatively low LH environment when COS begins, which is generally beneficial for egg development. However, if GnRHa are administered starting concomitant with gonadotropin stimulation (see GnRHa –“flare protocol” -below) it can cause an immediate surge in LH release, potentially leading to high levels of ovarian testosterone that can harm egg quality, especially in older women and those with diminished ovarian reserve (DOR).
- Gonadotropin releasing hormone antagonists (GnRH-antagonists) : Examples are Ganirelix, Cetrotide, and Orgalutron. GnRH antagonists (take days work quickly (within hours) to block pituitary LH release. Their purpose is to prevent excessive LH release during COS. In contrast, the LH-lowering effect of GnRH agonists takes several days to develop. Traditionally, GnRH antagonists are given starting on the 5th-7th day of gonadotropin stimulation. However, in older women and those with DOR, suppressing LH might happen too late to prevent excessive ovarian androgen production that can negatively impact egg development in the early stages of stimulation. That’s why I prefer to administer GnRH-antagonists right from the beginning of gonadotropin administration.
USING BIRTH CONTROL PILLS TO START OVARIAN STIMULATION:
Patients are often told that using birth control pills (BCP) to begin ovarian stimulation will suppress the response of the ovaries. This is true, but only if the BCP is not used correctly. Here’s the explanation:
In natural menstrual cycles and cycles stimulated with fertility drugs, the follicles in the ovaries need to develop receptors that respond to follicle-stimulating hormone (FSH) in order to properly respond to FSH stimulation. Pre-antral follicles (PAFs) do not have these receptors and cannot respond to FSH stimulation. The development of FSH responsivity requires exposure of the pre-antral follicles to FSH for several days, during which they become antral follicles (AFs) and gain the ability to respond to FSH-gonadotropin stimulation. In regular menstrual cycles, the rising FSH levels naturally convert PAFs to AFs. However, the combined BCP suppresses FSH. To counter this suppression, we need to promote increased FSH production several days before starting COS. This allows the orderly conversion from PAFs to AFs, ensuring proper follicle and egg development.
GnRHa causes an immediate surge in FSH release by the pituitary gland, promoting the conversion from PAF to AF. Therefore, when women take the BCP control pill to launch a cycle of COS, they need to overlap the BCP with a GnRHa for a few days before menstruation. This allows the early recruited PAFs to complete their development and reach the AF stage, so they can respond appropriately to ovarian stimulation. By adjusting the length of time, the woman is on the birth control pill, we can regulate and control the timing of the IVF treatment cycle. Without this step, initiating ovarian stimulation in women coming off birth control pills would be suboptimal.
PROTOCOLS FOR CONTROLLED OVARIAN STIMULATION (COS):
- GnRH Agonist Ovarian Stimulation Protocols:
- The long GnRHa protocol: Here, a GnRHa (usually Lupron or Superfact) is given either in a natural cycle, starting 5-7 days before menstruation, overlapping with the BCP for three days. Thereupon, the pill is stopped, while daily GnRHa injections continue until menstruation occurs (usually 5-7 days later). The GnRHa causes a rapid rise in FSH and LH levels. This is followed about 3-4 days later , by a progressive decline in FSH and LH to near zero levels, with a concomitant drop in ovarian estradiol and progesterone. This, in turn triggers uterine withdrawal bleeding (menstruation) within 5-7 days of starting the GnRHa administration. Gonadotropin treatment is then initiated while daily GnRHa injections continue to maintain a relatively low LH environment. Gonadotropin administration continues until the hCG “trigger” (see below).
- Short GnRH-Agonist (“Flare”) Protocol: This protocol involves starting hormone therapy and using GnRH agonist at the same time. The goal is to boost FSH so that with concomitant stimulation with FSH-gonadotropins + the GnRHa-induced surge in pituitary gland FSH release, will augment follicle development. However, this surge also leads to a rise in LH levels, which can cause an excessive production of ovarian male hormones (e.g., testosterone). This could potentially adversely affect the quality of eggs, especially in women over 39 years old, those with low ovarian reserve, and women with PCOS or DOR who already have increased LH sensitivity. In this way, these “flare protocols” can potentially decrease the success rates of IVF. While they are generally safe for younger women with normal ovarian reserve, I personally avoid using this approach on the off chance that even patients with normal ovarian reserve, might experience poor egg quality.
- GnRH Antagonist-Ovarian Stimulation Protocols:
- Conventional GnRH Antagonist Protocol: In this approach, daily GnRH antagonist injections are given from the 5th to the 8th day of COS with gonadotropins to the day of the “trigger” (see below). Accordingly, although rapidly acting to lower LH , this effect of GnRH- antagonist only starts suppressing LH from well into the COS cycle which means the ovarian follicles are left exposed and unshielded from pituitary gland -produced, (endogenous) LH during the first several days of stimulation. This can be harmful, especially in the early stage of COS when eggs and follicles are most vulnerable to the effects of over-produced LH-induced excessive ovarian testosterone. Therefore, I believe the Conventional GnRH Antagonist Protocol is not ideal for older women, those with low ovarian reserve, and women with PCOS who already have elevated LH activity. However, this protocol is acceptable for younger women with normal ovarian reserve, although I personally avoid using this approach on the off chance that even patients with normal ovarian reserve, might experience poor egg quality.
It’s important to note that the main reason for using GnRH antagonists is to prevent a premature LH surge, which is associated with poor egg and embryo quality due to follicular exhaustion. However, calling it a “premature LH surge” is misleading because it actually represents the culmination of a progressive increase in LH-induced ovarian testosterone. A better term would be “premature luteinization”. In some such cases, the rise in LH can precipitate “premature ovulation”.
- Agonist/Antagonist Conversion Protocol (A/ACP): I recommend this protocol for many of my patients, especially for older women and those with DOR or PCOS. The woman starts by taking a BCP for 7-10 days. This overlapped with a GnRHa for 3 days and continued until menstruation ensues about 5-7 days later. At this point she “converts” from the GnRH-agonist to a GnRH-antagonist (Ganirelix, Orgalutron, or Cetrotide). A few days after this conversion from agonist to antagonist, COS with gonadotropin stimulation starts. Both the antagonist and the gonadotropins are continued together until the hCG trigger. The purpose is to suppress endogenous LH release throughout the COS process and so avoid over-exposure of follicles and eggs to LH-induced excessive ovarian testosterone which as previously stated, can compromise egg and follicle growth and development. Excessive ovarian testosterone can also adversely affect estrogen-induced growth of the uterine lining (endometrium). Unlike GnRH-agonists, antagonists do not suppress ovarian response to the gonadotropin stimulation. This is why the A/ACP is well-suited for older women and those with diminished ovarian reserve.
- A/ACP with estrogen priming: This is a modified version of the A/ACP protocol used for women with very low ovarian reserve (AMH=<0.2ng/ml). Estrogen priming is believed to enhance the response of follicles to gonadotropins. Patients start their treatment cycle by taking a combined birth control pill (BCP) for 7-10 days. After that, they overlap daily administration of a GnRH agonist with the BCP for 3 days. The BCP is then stopped, and the daily agonist continues until menstruation ensues (usually 5-7 days later). At this point, the GnRH agonist is supplanted by daily injections of GnRH antagonist and Estradiol (E2) “priming” begins using E2 skin patches or intramuscular estradiol valerate injections twice weekly, while continuing the GnRH antagonist. Seven days after starting the estrogen priming COS begins using recombinant FSHr such as Follistim, Gonal-F or Puregon) +menotropin (e.g., Menopur) . The estrogen “priming” continues to the day of the “trigger” (see below). Egg retrieval is performed 36 hours after the trigger.
Younger women (under 30 years) and women with absent, irregular, or dysfunctional ovulation, as well as those with polycystic ovarian syndrome (PCOS), are at risk of developing a severe condition called Ovarian Hyperstimulation Syndrome (OHSS), which can be life-threatening. To predict this condition, accurate daily blood E2 level monitoring is required.
TRIGGERING “EGG MATURATION PRIOR TO EGG RETRIEVAL”
- The hCG “trigger”: When it comes to helping eggs mature before retrieval, one of the important decisions the doctor needs to make is choosing the “trigger shot” to facilitate the process. Traditionally, hCG (human chorionic gonadotropin) is derived from the urine of pregnant women (hCGu) while a newer recombinant hCG (hCGr), Ovidrel was recently The ideal dosage of hCGu is 10,000U and for Ovidrel, the recommended dosage is 500mcg. Both have the same efficacy. The “trigger” is usually administered by intramuscular injection, 34-36 hours prior to egg retrieval.
Some doctors may choose to lower the dosage of hCG if there is a risk of severe ovarian hyperstimulation syndrome (OHSS). However, I believe that a low dose of hCG (e.g., 5000 units of hCGu or 250 mcg of hCGr ( Ovidrel) might not be enough to optimize egg maturation, especially when there are many follicles. Instead, I suggest using a method called “prolonged coasting” to reduce the risk of OHSS.
- Using GnRH antagonist alone or combined with hCG as the trigger: Some doctors may prefer to use a GnRH- agonist trigger instead of hCG to reduce the risk of OHSS. The GnRHa “trigger” acts by inducing a “surge of pituitary gland-LH. However, it is difficult to predict the amount of LH that is released in response to a standard agonist trigger. In my opinion, using hCG is a better choice, even in cases of ovarian hyperstimulation, with the condition that “prolonged coasting” is implemented beforehand.
- Combined use of hCG + GnRH agonist: This approach is better than using a GnRH agonist alone but still not as effective as using the appropriate dosage of hCG.
- Timing of the trigger: The trigger shot should be given when the majority of ovarian follicles have reached a size of more than 15 mm, with several follicles measuring 18-22 mm. Follicles larger than 22 mm often contain overdeveloped eggs, while follicles smaller than 15 mm usually have underdeveloped and potentially abnormal eggs.
SEVERE OVARIAN HYPERSTIMULATION SYNDROME (OHSS) & “PROLONGED COASTING”
OHSS is a life-threatening condition that can occur during controlled ovarian stimulation (COS) when the blood E2 (estradiol) level rises too high. It is more common in young women with high ovarian reserve, women with polycystic ovarian syndrome (PCOS), and young women who do not ovulate spontaneously. To prevent OHSS, some doctors may trigger egg maturation earlier, use a lower dosage of hCG, or “trigger” using a GnRHa. However, these approaches can compromise egg and embryo quality and reduce the chances of success.
To protect against the risk of OHSS while optimizing egg quality, Physicians can use one of two options. The first is “prolonged coasting,” a procedure I introduced more than three decades ago. It involves stopping gonadotropin therapy while continuing to administer the GnRHa until the risk of OHSS has decreased. The precise timing of “prolonged coasting” is critical. It should be initiated when follicles have reached a specific size accompanied and the blood estradiol has reached a certain peak. The second option is to avoid fresh embryo transfer and freeze all “competent” embryos for later frozen embryo transfers (FETs) at a time when the risk of OHSS has subsided. By implementing these strategies, both egg/embryo quality and maternal well-being can be maximized.
In the journey of fertility, a woman is blessed with a limited number of eggs, like precious treasures awaiting their time. As she blossoms into womanhood, these eggs are gradually used, and the reserves start to fade. Yet, the power of hope and science intertwines, as we strive to support the development of these eggs through personalized treatment. We recognize that each woman is unique, and tailoring the protocol to her individual needs can unlock the path to success. We embrace the delicate timing, understanding that not all embryos are destined for greatness. With age, the odds may shift, but our dedication remains steadfast, along with our ultimate objective, which is to do everything possible to propagate of a normal pregnancy while optimizing the quality of that life after birth and all times, minimizing risk to the prospective parents.

Name: Yasmin G
Hi Dr. I’m 39 with amh of 0.3 and going through my 3rd ivf cycle. Because of lab availability for PGS they are looking at delaying my priming and injections, starting my priming on CD19 (my cycle is 24 days) of this cycle until CD6 of the next cycle, 1 day washout and starting injections on CD8. They are claiming that as long that I’m taking E2 priming my hormones should stay down.
I’m concerned that starting so late in the luteal phase and so late with the injections will heart my cycle and I will have a lead follicle at that point. What do you think?
Thank you!
Answer:
There are different philosophies regarding ovarian stimulation protocols. Of one thing I personally have no doubt about and that is that the protocol used needs to be tailored to the individual. I wish I could advise you directly but to do so I would need much more information. If interested, feel free to contact my assistant, Patti Converse at 702-533-2691 and set up an online consultation with me to discuss in-depth.
In the interim, I suggest you read the article below for context.

Egg/Embryo Quality in IVF
Geoffrey Sher MD
The journey of in vitro fertilization can be a rollercoaster of emotions for many patients. Often times they have to face the harsh reality that the number and quality of eggs retrieved has fallen short of their expectations. Then, should fertilization of these eggs not propagate chromosomally normal (euploid), “competent” embryos suitable for transfer to the uterus, many such patients find themselves in a state of emotional distress. They grapple with the inevitable questions of why this happened and how to prevent it from occurring again in the future. This article aims to delve into these queries, providing insights, rational explanations, and therapeutic options. It is an invitation to explore the light at the end of the tunnel. Readers are urged to carefully absorb the entirety of the article in the hope of finding valuable information and renewed hope.
The Importance of Chromosomal Integrity
While sperm quality is an important factor, egg quality is by far the most important when it comes to the generation of embryos that are capable of propagating healthy babies (“competent”). In this regard, chromosomal integrity of the egg and embryo, although it is not the only factor , is certainly the main determinant of such competency.
The woman’s age
About two thirds of a woman’s eggs in her twenties or early thirties have the correct number of chromosomes, which is necessary for a healthy pregnancy. As a woman gets older, the percentage of eggs with the right number of chromosomes decreases. By age 40, only about one in every 5-6 eggs is likely to be normal, and by the mid-forties, less than one in ten eggs will be normal.
Ovarian Reserve
A woman is born with all the eggs she will ever have. She starts using these eggs when she begins ovulating during puberty. At first, the eggs are used up quickly, but as she gets older, the number of eggs starts to run out. Her brain and pituitary gland try to stimulate the production of more eggs by increasing the output of Follicle Stimulating Hormone (FSH), but unfortunately, this often doesn’t work. When the number of remaining eggs in her ovaries falls below a certain level (which can be different for each woman), her FSH level rises, and production of the ovarian hormone, AMH decreases. This is the start of diminishing ovarian reserve (DOR). Most women experience the onset of DOR in their late 30s or early 40s, but it can happen earlier for some. The lower the ovarian reserve, the lower the AMH level will be, and the fewer eggs will be available for harvesting during IVF-egg retrieval. In such cases, a higher dosage of fertility drugs might be needed to promote better egg production in future attempts. . On the other hand, higher AMH levels mean more eggs are available, and lower doses of fertility drugs are usually needed. DOR is commonly associated with increased bioactivity of pituitary gland-produced LH. This LH activates production of ovarian male hormones (androgens)…predominantly testosterone by ovarian connective tissue (stroma) . While a small amount of ovarian testosterone is absolutely necessary for optimal follicle and egg development, excessive ovarian testosterone will often access the follicle , and compromise both egg quality and follicle growth and development. In some cases, rapidly increasing LH-release (“premature LH-surge”) with excessive induced ovarian testosterone can lead to “premature luteinization” of the follicles with cessation in growth and even to“ premature ovulation”.
Importance of Individualized Controlled Ovarian Stimulation (COS) Protocol
It’s not surprising that DOR is more common in older women, but regardless of age, having DOR makes a woman’s eggs more likely to be compromised during controlled ovarian stimulation (COS). The choice of the COS protocol is crucial to preventing unintentional harm to egg and embryo quality. The wrong protocol can disrupt normal egg development and increase the risk of abnormal embryos. That’s why it’s important to tailor the COS protocol to each individual’s needs. This helps optimize follicle growth and the quality of eggs and embryos. The timing of certain treatments is also important for successful outcomes.
Embryo Competency and Blastocyst Development
Embryos that don’t develop into blastocysts by day 6 after fertilization are usually chromosomally abnormal or aneuploid (”incompetent”) and not suitable for transfer. However, not all blastocysts are guaranteed to be normal and capable of developing into a healthy baby. As a woman gets older, the chances of a her embryos being chromosomally normal blastocyst decreases. For example, a blastocyst from a 30-year-old woman is more likely to be normal compared to one from a 40-year-old woman.
The IVF stimulation protocol has a big impact on the quality of eggs and embryos especially in women with DOR. Unfortunately, many IVF doctors use the same COS “recipe approach” for everyone without considering individual differences. Using personalized protocols can greatly improve the success of IVF. While we can’t change genetics or reverse a woman’s age, a skilled IVF specialist can customize the COS protocol to meet each patient’s specific needs.
GnRHa and GnRH-antagonists
Gonadotropin releasing hormone agonists (GnRHa)
Examples are Lupron, Buserelin, Superfact, and Decapeptyl . These are commonly used to launch ovarian stimulation cycles. They work by initially causing a release of pituitary gonadotropins, followed by a decrease in LH and FSH levels within 4-7 days. This creates a relatively low LH environment when COS begins, which is generally beneficial for egg development. However, if GnRHa are administered starting concomitant with gonadotropin stimulation (see GnRHa –“flare protocol” -below) it can cause an immediate surge in LH release, potentially leading to high levels of ovarian testosterone that can harm egg quality, especially in older women and those with diminished ovarian reserve (DOR).
Gonadotropin releasing hormone antagonists (GnRH-antagonists)
Examples are Ganirelix, Cetrotide, and Orgalutron. GnRH antagonists (take days work quickly (within hours) to block pituitary LH release. Their purpose is to prevent excessive LH release during COS. In contrast, the LH-lowering effect of GnRH agonists takes several days to develop. Traditionally, GnRH antagonists are given starting on the 5th-7th day of gonadotropin stimulation. However, in older women and those with DOR, suppressing LH might happen too late to prevent excessive ovarian androgen production that can negatively impact egg development in the early stages of stimulation. That’s why I prefer to administer GnRH-antagonists right from the beginning of gonadotropin administration.
Using Birth Control Pills to Start Ovarian Stimulation
Patients are often told that using birth control pills (BCP) to begin ovarian stimulation will suppress the response of the ovaries. This is true, but only if the BCP is not used correctly. Here’s the explanation:
In natural menstrual cycles and cycles stimulated with fertility drugs, the follicles in the ovaries need to develop receptors that respond to follicle-stimulating hormone (FSH) in order to properly respond to FSH stimulation. Pre-antral follicles (PAFs) do not have these receptors and cannot respond to FSH stimulation. The development of FSH responsivity requires exposure of the pre-antral follicles to FSH for several days, during which they become antral follicles (AFs) and gain the ability to respond to FSH-gonadotropin stimulation. In regular menstrual cycles, the rising FSH levels naturally convert PAFs to AFs. However, the combined BCP suppresses FSH. To counter this suppression, we need to promote increased FSH production several days before starting COS. This allows the orderly conversion from PAFs to AFs, ensuring proper follicle and egg development.
GnRHa causes an immediate surge in FSH release by the pituitary gland, promoting the conversion from PAF to AF. Therefore, when women take the BCP control pill to launch a cycle of COS, they need to overlap the BCP with a GnRHa for a few days before menstruation. This allows the early recruited PAFs to complete their development and reach the AF stage, so they can respond appropriately to ovarian stimulation. By adjusting the length of time, the woman is on the birth control pill, we can regulate and control the timing of the IVF treatment cycle. Without this step, initiating ovarian stimulation in women coming off birth control pills would be suboptimal.
Protocols for Controlled Ovarian Stimulation (COS)
- GnRH Agonist Ovarian Stimulation Protocols:
- The long GnRHa protocol: Here, a GnRHa (usually Lupron or Superfact) is given either in a natural cycle, starting 5-7 days before menstruation, overlapping with the BCP for three days. Thereupon, the pill is stopped, while daily GnRHa injections continue until menstruation occurs (usually 5-7 days later). The GnRHa causes a rapid rise in FSH and LH levels. This is followed about 3-4 days later , by a progressive decline in FSH and LH to near zero levels, with a concomitant drop in ovarian estradiol and progesterone. This, in turn triggers uterine withdrawal bleeding (menstruation) within 5-7 days of starting the GnRHa administration. Gonadotropin treatment is then initiated while daily GnRHa injections continue to maintain a relatively low LH environment. Gonadotropin administration continues until the hCG “trigger” (see below).
- Short GnRH-Agonist (“Flare”) Protocol: This protocol involves starting hormone therapy and using GnRH agonist at the same time. The goal is to boost FSH so that with concomitant stimulation with FSH-gonadotropins + the GnRHa-induced surge in pituitary gland FSH release, will augment follicle development. However, this surge also leads to a rise in LH levels, which can cause an excessive production of ovarian male hormones (e.g., testosterone). This could potentially adversely affect the quality of eggs, especially in women over 39 years old, those with low ovarian reserve, and women with PCOS or DOR who already have increased LH sensitivity. In this way, these “flare protocols” can potentially decrease the success rates of IVF. While they are generally safe for younger women with normal ovarian reserve, I personally avoid using this approach on the off chance that even patients with normal ovarian reserve, might experience poor egg quality.
- GnRH Antagonist-Ovarian Stimulation Protocols:
- Conventional GnRH Antagonist Protocol: In this approach, daily GnRH antagonist injections are given from the 5th to the 8th day of COS with gonadotropins to the day of the “trigger” (see below).

However, calling it a “premature LH surge” is misleading because it actually represents the culmination of a progressive increase in LH-induced ovarian testosterone. A better term would be “premature luteinization”. In some such cases, the rise in LH can precipitate “premature ovulation”.
- Agonist/Antagonist Conversion Protocol (A/ACP): I recommend this protocol for many of my patients, especially for older women and those with DOR or PCOS. The woman starts by taking a BCP for 7-10 days. This overlapped with a GnRHa for 3 days and continued until menstruation ensues about 5-7 days later. At this point she “converts” from the GnRH-agonist to a GnRH-antagonist (Ganirelix, Orgalutron, or Cetrotide). A few days after this conversion from agonist to antagonist, COS with gonadotropin stimulation starts. Both the antagonist and the gonadotropins are continued together until the hCG trigger. The purpose is to suppress endogenous LH release throughout the COS process and so avoid over-exposure of follicles and eggs to LH-induced excessive ovarian testosterone which as previously stated, can compromise egg and follicle growth and development. Excessive ovarian testosterone can also adversely affect estrogen-induced growth of the uterine lining (endometrium). Unlike GnRH-agonists, antagonists do not suppress ovarian response to the gonadotropin stimulation. This is why the A/ACP is well-suited for older women and those with diminished ovarian reserve.
- A/ACP with estrogen priming: This is a modified version of the A/ACP protocol used for women with very low ovarian reserve (AMH=<0.2ng/ml). Estrogen priming is believed to enhance the response of follicles to gonadotropins, which leads to successful IVF outcomes.

The BCP is then stopped, and the daily agonist continues until menstruation ensues (usually 5-7 days later). At this point, the GnRH agonist is supplanted by daily injections of GnRH antagonist and Estradiol (E2) “priming” begins using E2 skin patches or intramuscular estradiol valerate injections twice weekly, while continuing the GnRH antagonist. Seven days after starting the estrogen priming in IVF, COS begins using recombinant FSHr such as Follistim, Gonal-F or Puregon) +menotropin (e.g., Menopur). The estrogen “priming” continues to the day of the “trigger” (see below). Egg retrieval is performed 36 hours after the trigger.
Younger women (under 30 years) and women with absent, irregular, or dysfunctional ovulation, as well as those with polycystic ovarian syndrome (PCOS), are at risk of developing a severe condition called Ovarian Hyperstimulation Syndrome (OHSS), which can be life-threatening. To predict this condition, accurate daily blood E2 level monitoring is required.
TRIGGERING “EGG MATURATION PRIOR TO EGG RETRIEVAL”
- The hCG “trigger”: When it comes to helping eggs mature before retrieval, one of the important decisions the doctor needs to make is choosing the “trigger shot” to facilitate the process. Traditionally, hCG (human chorionic gonadotropin) is derived from the urine of pregnant women (hCGu) while a newer recombinant hCG (hCGr), Ovidrel was recently The ideal dosage of hCGu is 10,000U and for Ovidrel, the recommended dosage is 500mcg. Both have the same efficacy. The “trigger” is usually administered by intramuscular injection, 34-36 hours prior to egg retrieval.
Some doctors may choose to lower the dosage of hCG if there is a risk of severe ovarian hyperstimulation syndrome (OHSS). However, I believe that a low dose of hCG (e.g., 5000 units of hCGu or 250 mcg of hCGr ( Ovidrel) might not be enough to optimize egg maturation, especially when there are many follicles. Instead, I suggest using a method called “prolonged coasting” to reduce the risk of OHSS.
- Using GnRH antagonist alone or combined with hCG as the trigger: Some doctors may prefer to use a GnRH-agonist trigger instead of hCG to reduce the risk of OHSS. The GnRHa “trigger” acts by inducing a “surge of pituitary gland-LH. However, it is difficult to predict the amount of LH that is released in response to a standard agonist trigger. In my opinion, using hCG is a better choice, even in cases of ovarian hyperstimulation, with the condition that “prolonged coasting” is implemented beforehand.
- Combined use of hCG + GnRH agonist: This approach is better than using a GnRH agonist alone but still not as effective as using the appropriate dosage of hCG.
- Timing of the trigger: The trigger shot should be given when the majority of ovarian follicles have reached a size of more than 15 mm, with several follicles measuring 18-22 mm. Follicles larger than 22 mm often contain overdeveloped eggs, while follicles smaller than 15 mm usually have underdeveloped and potentially abnormal eggs.
SEVERE OVARIAN HYPERSTIMULATION SYNDROME (OHSS) & “PROLONGED COASTING”
OHSS is a life-threatening condition that can occur during controlled ovarian stimulation (COS) when the blood E2 (estradiol) level rises too high. It is more common in young women with high ovarian reserve, women with polycystic ovarian syndrome (PCOS), and young women who do not ovulate spontaneously. To prevent OHSS, some doctors may trigger egg maturation earlier, use a lower dosage of hCG, or “trigger” using a GnRHa. However, these approaches can compromise egg and embryo quality and reduce the chances of success.
To protect against the risk of OHSS while optimizing egg quality, physicians can use one of two options. The first is “prolonged coasting,” a procedure I introduced more than three decades ago. It involves stopping gonadotropin therapy while continuing to administer the GnRHa until the risk of OHSS has decreased. The precise timing of “prolonged coasting” is critical.

The second option is to avoid fresh embryo transfer and freeze all “competent” embryos for later frozen embryo transfers (FETs) at a time when the risk of OHSS has subsided.

Hi Dr. Sher,
I’ve been through 8 IVF cycles with two separate clinics. Overall, despite changes to protocols, I’ve encountered the same issues. The first issue is that, though my ovaries produce a good number of oocytes, not enough of them are mature. The second issue is that very few of them seem to make it to day 5 blastocysts. There is no MFI. I’m wondering if you could help recommend a protocol. Below are details of how it’s gone overall:
Total results of all cycles (***doesn’t include Cycle 1)
138 oocytes retrieved
93 mature oocytes (67%)
73 fertilized (78%)
16 blastocysts (22%)
6 euploids (37.5% transferrable)
If including 1 low risk mosaic (44% transferrable)
If including 4 high risk mosaic (69% transferrable)
The reason why I didn’t include results of our first cycle is because our first cycle was a standard short protocol. At the time, although I was 34 and showed an AMH of 4.3, only a few follicles responded to stims very quickly, resulting in a stim period of 2-3 days before retrieval. We did prep for this particular cycle with birth control (which I’ve not taken since this cycle). Because we had these issues with synchronization, neither clinic I worked with prescribed the short protocol with me again. Every cycle since then has been the long protocol, which for me meant I was started on 10ml of Lupron for 7-10 days prior to my period which I continued it through stim at 5 ml until HCG trigger.
By the way, I have been diagnosed with PCOS before, though I am lean and some doctors seem to think I don’t have it. I’ve always been an “on the fence” case. However, my high AMH, poor egg quality, oily skin, and sugar cravings convinces me I do.
Anyway, doctors have basically had 3 separate approaches to stims with me, all of which are long protocol. They are:
1) what I’d call “Normal” – 150iu of FSH + 150 iu of menopur a day (usually 8 days) until hcg trigger.
2) what I’d call “low LH” – 300iu of FSH for 4 days, then 150 iu of FSH + 150 iu of menopur for 4 days until hcg trigger
3) what I’d call “high LH” – 300iu of menopur (actually it wasn’t menopur but some kind of stim with a lot of LH) until hcg trigger
Below are the outcomes of the 3 different stim protocols:
Normal Stim Outcomes (3 cycles, 34 & 35 yo)
77 oocytes retrieved
41 mature (53%)
31 fertilized (76%)
8 blastocysts (26%)
3 euploids (37.5% transferrable)
If including 1 low risk mosaic (50% transferrable)
If including 2 high risk mosaic (62.5% transferrable)
Low LH Stim Outcomes (2 cycles, 35 & 37 yo):
50 oocytes
34 mature (68%)
28 fertilized (82%)
7 blastocysts (25%)
2 euploid (28.5% transferrable)
If including 2 high risk mosaics (57% transferrable)
High LH Stim Outcome (1 cycle, 37 yo):
24 retrieved
? mature (guess is 17-18 mature, so maybe 70%)
14 fertilized (78%)
1 blastocyst (7%)
1 euploid (100% transferrable)
As you can see, there doesn’t seem to be much difference between the “Normal” and the “Low LH” stim protocols. BUT, the one time the doctor prescribed a ton of LH in the effort to increase maturity rates in the “High LH”, there was an increase in mature eggs, but a huge decrease in egg quality. Clearly, though we only have a data set of one, a lot of LH seems to have a negative impact on egg quality, which is consistent with PCOS patients. Furthermore, though you can’t see this in the data I’ve included above, the BEST blastocysts I had was on a “Low LH” protocol. I had 2 euploids, one of which was AA and the other AB. Every other embryo I’ve ever had has been about BB, including all euploids.
Also one more thing – all hcg triggers have been 5000 iu except once I was given 10,000 iu. This was on my second IVF cycle when I was prescribed less stim dosage and only produced 10 oocytes. However, of the 10, 8 were mature, 5 were fertilized, and eventually only 1 went into blastocyst stage and came back euploid. This is only one data set but it makes me wonder if the high HCG dose was responsible for the higher maturity rate, or if that happened because my ovaries had less eggs to handle at the time.
Anyway, from what I’m seeing, I think the key takeaways are that LH seems to have a negative impact on me, but I struggle with maturity rates. I’m wondering if you think doing stim with only FSH and ending with a high HCG dose at the end would help? Would prepping for IVF with birth control in conjunction with Lupron help?
I’m very curious to know. You’re the only doc I’ve ever seen online that has explained the connection between LH and egg quality. None of my REs ever mentioned this.
Thank you so much for your time.

A: EGG/ EMBRYO QUALITY IN IVF & HOW SELECTION OF THE IDEAL PROTOCOL FOR OVARIAN STIMULATION INFLUENCES EGG/EMBRYO QUALITY AND OUTCOME.
Geoffrey Sher MD
The journey of in vitro fertilization can be a rollercoaster of emotions for many patients. Often times they have to face the harsh reality that the number and quality of eggs retrieved has fallen short of their expectations. Then, should fertilization of these eggs not propagate chromosomally normal (euploid), “competent” embryos suitable for transfer to the uterus, many such patients find themselves in a state of emotional distress. They grapple with the inevitable questions of why this happened and how to prevent it from occurring again in the future. This article aims to delve into these queries, providing insights, rational explanations, and therapeutic options. It is an invitation to explore the light at the end of the tunnel. Readers are urged to carefully absorb the entirety of the article in the hope of finding valuable information and renewed hope.
- The Importance of Chromosomal Integrity: While sperm quality is an important factor, egg quality is by far the most important when it comes to the generation of embryos that are capable of propagating healthy babies (“competent”). In this regard, chromosomal integrity of the egg and embryo, although it is not the only factor , is certainly the main determinant of such competency.
- The woman’s age: About two thirds of a woman’s eggs in her twenties or early thirties have the correct number of chromosomes, which is necessary for a healthy pregnancy. As a woman gets older, the percentage of eggs with the right number of chromosomes decreases. By age 40, only about one in every 5-6 eggs is likely to be normal, and by the mid-forties, less than one in ten eggs will be normal.
- Ovarian Reserve (number of available in the ovaries): A woman is born with all the eggs she will ever have. She starts using these eggs when she begins ovulating during puberty. At first, the eggs are used up quickly, but as she gets older, the number of eggs starts to run out. Her brain and pituitary gland try to stimulate the production of more eggs by increasing the output of Follicle Stimulating Hormone (FSH), but unfortunately, this often doesn’t work. When the number of remaining eggs in her ovaries falls below a certain level (which can be different for each woman), her FSH level rises, and production of the ovarian hormone, AMH decreases. This is the start of diminishing ovarian reserve (DOR). Most women experience the onset of DOR in their late 30s or early 40s, but it can happen earlier for some. The lower the ovarian reserve, the lower the AMH level will be, and the fewer eggs will be available for harvesting during IVF-egg retrieval. In such cases, a higher dosage of fertility drugs might be needed to promote better egg production in future attempts. . On the other hand, higher AMH levels mean more eggs are available, and lower doses of fertility drugs are usually needed. DOR is commonly associated with increased bioactivity of pituitary gland-produced LH. This LH activates production of ovarian male hormones (androgens)…predominantly testosterone by ovarian connective tissue (stroma) . While a small amount of ovarian testosterone is absolutely necessary for optimal follicle and egg development, excessive ovarian testosterone will often access the follicle , and compromise both egg quality and follicle growth and development. In some cases, rapidly increasing LH-release (“premature LH-surge”) with excessive induced ovarian testosterone can lead to “premature luteinization” of the follicles with cessation in growth and even to“ premature ovulation”.
- Importance of Individualized Controlled Ovarian Stimulation (COS) Protocol: It’s not surprising that DOR is more common in older women, but regardless of age, having DOR makes a woman’s eggs more likely to be compromised during controlled ovarian stimulation (COS). The choice of the COS protocol is crucial to preventing unintentional harm to egg and embryo quality. The wrong protocol can disrupt normal egg development and increase the risk of abnormal embryos. That’s why it’s important to tailor the COS protocol to each individual’s needs. This helps optimize follicle growth and the quality of eggs and embryos. The timing of certain treatments is also important for successful outcomes.
- Embryo Competency and Blastocyst Development: Embryos that don’t develop into blastocysts by day 6 after fertilization are usually chromosomally abnormal or aneuploid (”incompetent”) and not suitable for transfer. However, not all blastocysts are guaranteed to be normal and capable of developing into a healthy baby. As a woman gets older, the chances of a her embryos being chromosomally normal blastocyst decreases. For example, a blastocyst from a 30-year-old woman is more likely to be normal compared to one from a 40-year-old woman.
The IVF stimulation protocol has a big impact on the quality of eggs and embryos especially in women with DOR. Unfortunately, many IVF doctors use the same COS “recipe approach” for everyone without considering individual differences. Using personalized protocols can greatly improve the success of IVF. While we can’t change genetics or reverse a woman’s age, a skilled IVF specialist can customize the COS protocol to meet each patient’s specific needs.
GONADOTROPIN RELEASING HORMONE AGONISTS (GNRHA) AND GNRH-ANTAGONISTS:
- Gonadotropin releasing hormone agonists (GnRHa). Examples are Lupron, Buserelin, Superfact, and Decapeptyl . These are commonly used to launch ovarian stimulation cycles. They work by initially causing a release of pituitary gonadotropins, followed by a decrease in LH and FSH levels within 4-7 days. This creates a relatively low LH environment when COS begins, which is generally beneficial for egg development. However, if GnRHa are administered starting concomitant with gonadotropin stimulation (see GnRHa –“flare protocol” -below) it can cause an immediate surge in LH release, potentially leading to high levels of ovarian testosterone that can harm egg quality, especially in older women and those with diminished ovarian reserve (DOR).
- Gonadotropin releasing hormone antagonists (GnRH-antagonists) : Examples are Ganirelix, Cetrotide, and Orgalutron. GnRH antagonists (take days work quickly (within hours) to block pituitary LH release. Their purpose is to prevent excessive LH release during COS. In contrast, the LH-lowering effect of GnRH agonists takes several days to develop. Traditionally, GnRH antagonists are given starting on the 5th-7th day of gonadotropin stimulation. However, in older women and those with DOR, suppressing LH might happen too late to prevent excessive ovarian androgen production that can negatively impact egg development in the early stages of stimulation. That’s why I prefer to administer GnRH-antagonists right from the beginning of gonadotropin administration.
USING BIRTH CONTROL PILLS TO START OVARIAN STIMULATION:
Patients are often told that using birth control pills (BCP) to begin ovarian stimulation will suppress the response of the ovaries. This is true, but only if the BCP is not used correctly. Here’s the explanation:
In natural menstrual cycles and cycles stimulated with fertility drugs, the follicles in the ovaries need to develop receptors that respond to follicle-stimulating hormone (FSH) in order to properly respond to FSH stimulation. Pre-antral follicles (PAFs) do not have these receptors and cannot respond to FSH stimulation. The development of FSH responsivity requires exposure of the pre-antral follicles to FSH for several days, during which they become antral follicles (AFs) and gain the ability to respond to FSH-gonadotropin stimulation. In regular menstrual cycles, the rising FSH levels naturally convert PAFs to AFs. However, the combined BCP suppresses FSH. To counter this suppression, we need to promote increased FSH production several days before starting COS. This allows the orderly conversion from PAFs to AFs, ensuring proper follicle and egg development.
GnRHa causes an immediate surge in FSH release by the pituitary gland, promoting the conversion from PAF to AF. Therefore, when women take the BCP control pill to launch a cycle of COS, they need to overlap the BCP with a GnRHa for a few days before menstruation. This allows the early recruited PAFs to complete their development and reach the AF stage, so they can respond appropriately to ovarian stimulation. By adjusting the length of time, the woman is on the birth control pill, we can regulate and control the timing of the IVF treatment cycle. Without this step, initiating ovarian stimulation in women coming off birth control pills would be suboptimal.
PROTOCOLS FOR CONTROLLED OVARIAN STIMULATION (COS):
- GnRH Agonist Ovarian Stimulation Protocols:
- The long GnRHa protocol: Here, a GnRHa (usually Lupron or Superfact) is given either in a natural cycle, starting 5-7 days before menstruation, overlapping with the BCP for three days. Thereupon, the pill is stopped, while daily GnRHa injections continue until menstruation occurs (usually 5-7 days later). The GnRHa causes a rapid rise in FSH and LH levels. This is followed about 3-4 days later , by a progressive decline in FSH and LH to near zero levels, with a concomitant drop in ovarian estradiol and progesterone. This, in turn triggers uterine withdrawal bleeding (menstruation) within 5-7 days of starting the GnRHa administration. Gonadotropin treatment is then initiated while daily GnRHa injections continue to maintain a relatively low LH environment. Gonadotropin administration continues until the hCG “trigger” (see below).
- Short GnRH-Agonist (“Flare”) Protocol: This protocol involves starting hormone therapy and using GnRH agonist at the same time. The goal is to boost FSH so that with concomitant stimulation with FSH-gonadotropins + the GnRHa-induced surge in pituitary gland FSH release, will augment follicle development. However, this surge also leads to a rise in LH levels, which can cause an excessive production of ovarian male hormones (e.g., testosterone). This could potentially adversely affect the quality of eggs, especially in women over 39 years old, those with low ovarian reserve, and women with PCOS or DOR who already have increased LH sensitivity. In this way, these “flare protocols” can potentially decrease the success rates of IVF. While they are generally safe for younger women with normal ovarian reserve, I personally avoid using this approach on the off chance that even patients with normal ovarian reserve, might experience poor egg quality.
- GnRH Antagonist-Ovarian Stimulation Protocols:
- Conventional GnRH Antagonist Protocol: In this approach, daily GnRH antagonist injections are given from the 5th to the 8th day of COS with gonadotropins to the day of the “trigger” (see below). Accordingly, although rapidly acting to lower LH , this effect of GnRH- antagonist only starts suppressing LH from well into the COS cycle which means the ovarian follicles are left exposed and unshielded from pituitary gland -produced, (endogenous) LH during the first several days of stimulation. This can be harmful, especially in the early stage of COS when eggs and follicles are most vulnerable to the effects of over-produced LH-induced excessive ovarian testosterone. Therefore, I believe the Conventional GnRH Antagonist Protocol is not ideal for older women, those with low ovarian reserve, and women with PCOS who already have elevated LH activity. However, this protocol is acceptable for younger women with normal ovarian reserve, although I personally avoid using this approach on the off chance that even patients with normal ovarian reserve, might experience poor egg quality.
It’s important to note that the main reason for using GnRH antagonists is to prevent a premature LH surge, which is associated with poor egg and embryo quality due to follicular exhaustion. However, calling it a “premature LH surge” is misleading because it actually represents the culmination of a progressive increase in LH-induced ovarian testosterone. A better term would be “premature luteinization”. In some such cases, the rise in LH can precipitate “premature ovulation”.
- Agonist/Antagonist Conversion Protocol (A/ACP): I recommend this protocol for many of my patients, especially for older women and those with DOR or PCOS. The woman starts by taking a BCP for 7-10 days. This overlapped with a GnRHa for 3 days and continued until menstruation ensues about 5-7 days later. At this point she “converts” from the GnRH-agonist to a GnRH-antagonist (Ganirelix, Orgalutron, or Cetrotide). A few days after this conversion from agonist to antagonist, COS with gonadotropin stimulation starts. Both the antagonist and the gonadotropins are continued together until the hCG trigger. The purpose is to suppress endogenous LH release throughout the COS process and so avoid over-exposure of follicles and eggs to LH-induced excessive ovarian testosterone which as previously stated, can compromise egg and follicle growth and development. Excessive ovarian testosterone can also adversely affect estrogen-induced growth of the uterine lining (endometrium). Unlike GnRH-agonists, antagonists do not suppress ovarian response to the gonadotropin stimulation. This is why the A/ACP is well-suited for older women and those with diminished ovarian reserve.
- A/ACP with estrogen priming: This is a modified version of the A/ACP protocol used for women with very low ovarian reserve (AMH=<0.2ng/ml). Estrogen priming is believed to enhance the response of follicles to gonadotropins. Patients start their treatment cycle by taking a combined birth control pill (BCP) for 7-10 days. After that, they overlap daily administration of a GnRH agonist with the BCP for 3 days. The BCP is then stopped, and the daily agonist continues until menstruation ensues (usually 5-7 days later). At this point, the GnRH agonist is supplanted by daily injections of GnRH antagonist and Estradiol (E2) “priming” begins using E2 skin patches or intramuscular estradiol valerate injections twice weekly, while continuing the GnRH antagonist. Seven days after starting the estrogen priming COS begins using recombinant FSHr such as Follistim, Gonal-F or Puregon) +menotropin (e.g., Menopur) . The estrogen “priming” continues to the day of the “trigger” (see below). Egg retrieval is performed 36 hours after the trigger.
Younger women (under 30 years) and women with absent, irregular, or dysfunctional ovulation, as well as those with polycystic ovarian syndrome (PCOS), are at risk of developing a severe condition called Ovarian Hyperstimulation Syndrome (OHSS), which can be life-threatening. To predict this condition, accurate daily blood E2 level monitoring is required.
TRIGGERING “EGG MATURATION PRIOR TO EGG RETRIEVAL”
- The hCG “trigger”: When it comes to helping eggs mature before retrieval, one of the important decisions the doctor needs to make is choosing the “trigger shot” to facilitate the process. Traditionally, hCG (human chorionic gonadotropin) is derived from the urine of pregnant women (hCGu) while a newer recombinant hCG (hCGr), Ovidrel was recently The ideal dosage of hCGu is 10,000U and for Ovidrel, the recommended dosage is 500mcg. Both have the same efficacy. The “trigger” is usually administered by intramuscular injection, 34-36 hours prior to egg retrieval.
Some doctors may choose to lower the dosage of hCG if there is a risk of severe ovarian hyperstimulation syndrome (OHSS). However, I believe that a low dose of hCG (e.g., 5000 units of hCGu or 250 mcg of hCGr ( Ovidrel) might not be enough to optimize egg maturation, especially when there are many follicles. Instead, I suggest using a method called “prolonged coasting” to reduce the risk of OHSS.
- Using GnRH antagonist alone or combined with hCG as the trigger: Some doctors may prefer to use a GnRH- agonist trigger instead of hCG to reduce the risk of OHSS. The GnRHa “trigger” acts by inducing a “surge of pituitary gland-LH. However, it is difficult to predict the amount of LH that is released in response to a standard agonist trigger. In my opinion, using hCG is a better choice, even in cases of ovarian hyperstimulation, with the condition that “prolonged coasting” is implemented beforehand.
- Combined use of hCG + GnRH agonist: This approach is better than using a GnRH agonist alone but still not as effective as using the appropriate dosage of hCG.
- Timing of the trigger: The trigger shot should be given when the majority of ovarian follicles have reached a size of more than 15 mm, with several follicles measuring 18-22 mm. Follicles larger than 22 mm often contain overdeveloped eggs, while follicles smaller than 15 mm usually have underdeveloped and potentially abnormal eggs.
SEVERE OVARIAN HYPERSTIMULATION SYNDROME (OHSS) & “PROLONGED COASTING”
OHSS is a life-threatening condition that can occur during controlled ovarian stimulation (COS) when the blood E2 (estradiol) level rises too high. It is more common in young women with high ovarian reserve, women with polycystic ovarian syndrome (PCOS), and young women who do not ovulate spontaneously. To prevent OHSS, some doctors may trigger egg maturation earlier, use a lower dosage of hCG, or “trigger” using a GnRHa. However, these approaches can compromise egg and embryo quality and reduce the chances of success.
To protect against the risk of OHSS while optimizing egg quality, Physicians can use one of two options. The first is “prolonged coasting,” a procedure I introduced more than three decades ago. It involves stopping gonadotropin therapy while continuing to administer the GnRHa until the risk of OHSS has decreased. The precise timing of “prolonged coasting” is critical. It should be initiated when follicles have reached a specific size accompanied and the blood estradiol has reached a certain peak. The second option is to avoid fresh embryo transfer and freeze all “competent” embryos for later frozen embryo transfers (FETs) at a time when the risk of OHSS has subsided. By implementing these strategies, both egg/embryo quality and maternal well-being can be maximized.
In the journey of fertility, a woman is blessed with a limited number of eggs, like precious treasures awaiting their time. As she blossoms into womanhood, these eggs are gradually used, and the reserves start to fade. Yet, the power of hope and science intertwines, as we strive to support the development of these eggs through personalized treatment. We recognize that each woman is unique, and tailoring the protocol to her individual needs can unlock the path to success. We embrace the delicate timing, understanding that not all embryos are destined for greatness. With age, the odds may shift, but our dedication remains steadfast, along with our ultimate objective, which is to do everything possible to propagate of a normal pregnancy while optimizing the quality of that life after birth and all times, minimizing risk to the prospective parents.

B. Understanding Polycystic Ovarian Syndrome (PCOS) and the Need to Customize Ovarian Stimulation Protocols.
Geoffrey Sher MD
Polycystic ovary syndrome (PCOS) is a common hormonal system disorder among women affecting between 5% and 10% of women of reproductive age worldwide. Women with PCOS may have enlarged ovaries that contain small collections of fluid — called follicles — located in each ovary as seen during an ultrasound. The condition is characterized by abnormal ovarian function (irregular or absent periods, abnormal or absent ovulation and infertility), androgenicity (increased body hair or hirsutism, acne) and increased body weight –body mass index or BMI. The ovaries of women with PCOS characteristically contain multiple micro-cysts often arranged like a “string of pearls” immediately below the ovarian surface (capsule).interspersed by an overgrowth of ovarian connective tissue (stroma).
PCOS is one of the most common causes of menstrual irregularities, infertility, and hirsutism, Despite an enormous effort to define its cause, the etiology of PCOS remains unclear, and there is no definite cure at this time. PCOS is clearly a heterogeneous disorder which often has a familial (genetic) basis. Infertility associated with PCOS has been attributed to numerous factors, including dysfunctional gonadotropin pituitary secretion, peripheral insulin resistance, elevated adrenal and/or ovarian androgen (male hormone) levels, and dysfunction of several growth factors. Women with this condition are often obese and insulin resistant. The compensatory hyperinsulinemia further stimulates ovarian androgen production which may be detrimental to egg maturation and there is a clear link between the degree of insulin resistance and anovulation. PCOS is also a significant long-term health risk for women, thus necessitating vigilance through regular annual examinations (non-insulin dependent diabetes mellitus, hypertension, hypercholesterolemia, cardiovascular disease and endometrial cancer). Whereas PCOS-related infertility is usually manageable through the use of fertility drugs, lifestyle changes (diet and exercise) remain a mainstay of long-term therapy. More recently, ovulation rates, circulating androgens, pregnancy rates and perhaps even first-trimester miscarriage rates have been shown to improve when insulin sensitizers like metformin are used to correct the underlying insulin resistance.
Most patients with PCOS are young and have excellent pregnancy rates with oral clomiphene. Those that require more aggressive treatments with injectable medications probably represent a subgroup of PCOS patients with severe ovarian dysfunction. These women often have explosive response to gonadotropins which can result in serious complications like Severe Ovarian Hyperstimulation Syndrome (OHSS…see below) and high order multiple births. In those women, the ability to perform “prolonged coasting” (see below) and selectively transfer fewer embryos during IVF offers a clear advantage over standard gonadotropin injections.
Egg quality in PCOS
The potential for a woman’s eggs to undergo orderly maturation, successful fertilization and subsequent progression to “good quality embryos” is in large part genetically determined. However, the expression of such potential is profoundly susceptible to numerous influences, especially intra-ovarian hormonal changes during the pre-ovulatory phase of the cycle. Proper follicular stimulation as well as precise timing of egg maturation with LH (Luteinizing Hormone) or hCG (human chorionic gonadotropin) is crucial to optimal egg maturation, fertilization and ultimately embryo quality. Both pituitary gonadotropins, LH and FSH (follicle stimulating hormone) play a pivotal but different role in follicular development. The action of FSH is mainly directed toward granulosa cell (cells lining the inside of the follicle) proliferation and estrogen production (E2). LH, on the other hand, acts primarily on the ovarian stroma (the connective tissue that surrounds the follicle) to produce androgens. While small amounts of ovarian androgens, such as testosterone, enhance egg and follicle development, over-exposure to them can have a deleterious effect. Furthermore, excessive ovarian androgens can also compromise estrogen-induced endometrial growth and development.
Suppressing pituitary secretion of LH with gonadotropin releasing hormone (GnRH) agonists such as Lupron®, is particularly useful in PCOS. In that condition, serum LH levels are elevated, leading to stromal overgrowth, follicular arrests (so-called cysts) and high levels of androgens synthesis. It is therefore not surprising that these follicles often yield poorly developed (“immature”) eggs” at the time of egg retrieval (ET) and that “poor egg/embryo quality”, inadequate endometrial development and high miscarriage rates are common features of this condition. However, contrary to popular belief, this is not due to an intrinsic deficit in “egg quality”. Stimulation protocols geared toward optimizing follicle and egg development and avoiding over exposure to androgens correct these problems ad result in pregnancy rates similar to those of non-PCOS women. Whereas the overuse of LH-containing preparations such as Menopur® and Luveris® further aggravates this effect. In conclusion, to maximize ultimate oocyte maturation, we strongly recommend against the exclusive use of such products in PCOS patients, preferring FSH-dominant products such as Folistim®, Gonal F® or Bravelle® over a period of at least 9 days following pituitary suppression with Lupron®.
PCOS women often have a family history of diabetes and demonstrable insulin resistance (evidenced by high blood insulin levels and an abnormal 2-hour glucose tolerance test).This underlying Diabetes mellitus tendency could play a role in the development of PCOS and contribute to the development of obesity, an abnormal blood lipid profile, and a predisposition to coronary vascular disease. Women with PCOS are slightly more at risk of developing uterine, ovarian and possibly also breast cancer in later life and accordingly should be evaluated for these conditions on a more frequent basis than would ordinarily be recommended to non-PCOS women.
Most women with PCOS either do not ovulate at all or they ovulate irregularly. As a consequence thereof they in addition usually experience delayed, absent or irregular menstruation. In addition, an inordinate percentage of the eggs produced by PCOS women following ovulation induction, tend to be chromosomally abnormal (aneuploid). Rather than being due to an intrinsic egg defect being inherent in PCOS women, the poor egg quality more than likely the result of over-exposure to male hormones (predominantly, testosterone) produced by the ovarian stroma. These two factors (ovulation dysfunction and poor egg quality) are the main reasons for the poor reproductive performance (infertility and an increased miscarriage rate) in PCOS women.
PCOS patients are at an inordinate risk of severely over-responding fertility drugs, both oral varieties (e.g. Clomiphene, Serophene & Femara) and especially the injectables (e.g. Follistim, Puregon, Gonal F, Menopur and Bravelle) by forming large numbers ovarian follicles. This can lead to life endangering complications associated with sever ovarian hyperstimulation (OHSS). In addition PCOS women receiving fertility drugs often experience multiple ovulations putting them at severe risk (40%+) of high order multiple pregnancy (i.e. triplets or greater) with often devastating consequences.
VARIETIES OF POLYCYSTIC OVARIAN SYNDROME:
1) Hypothalamic-pituitary-PCOS: This is the commonest form of PCOS and is often genetically transmitted and is characteristically associated with a blood concentration of Luteinizing Hormone (LH) that is uncharacteristically much higher than the Follicle Stimulating Hormone (FSH) level (FSH is normally higher than the LH concentration) as well as high-normal or blood androgen ( male) hormone concentrations (e.g. androstenedione, testosterone and dehydroepiandrosterone -DHEA).Hypothalamic-pituitary-ovarian PCOS is also often associated with insulin resistance and in about 40%-50% of the cases.
2) Adrenal PCOS: Here the excess of male hormones are derived from overactive adrenal glands rather than from the ovaries. Blood levels of testosterone and/or androstenedione raised but here, but here, the blood level of dehydroepiandrosterone (DHEAS) is also raised, clinching the diagnosis.
3) Severe pelvic adhesive disease secondary to severe endometriosis, chronic pelvic inflammatory disease and/or extensive pelvic surgery: Women who have this type of PCOS tend to less likely to hyperstimulate in response to ovulation induction . Their. DHEAS is also is not raised.
TREATMENT OF INFERTILITY DUE TO ASSOCIATED OVULATION DYSFUNCTION:
Hypothalamic-pituitary-/ovarian PCOS: Ovulation induction with fertility drugs such as clomiphene citrate, Letrozole (Femara) or gonadotropins, with or without intrauterine insemination (IUI) is often highly successful in establishing pregnancies in PCOS women. However, IVF is fast becoming a treatment of choice (see below).
In about 40% of cases, 3-6 months of oral Metformin (Glucophage) treatment results in a significant reduction of insulin resistance, lowering of blood androgen levels, an improvement in ovulatory function, and/or some amelioration of androgenous symptoms and signs.
Surgical treatment by “ovarian drilling” of the many small ovarian cysts lying immediately below the envelopment (capsule) of the ovaries, is often used, but is less successful than alternative non-surgical treatment and is only temporarily effective. The older form of surgical treatment, using ovarian wedge resection is rarely used any longer as it can produce severe pelvic adhesion formation.
Adrenal PCOS is treated with steroids such as prednisone or dexamethasone which over a period of several weeks will suppress adrenal androgen production, allowing regular ovulation to take place spontaneously. This is often combined with clomiphene, Letrozole and/or gonadotropin therapy to initiate ovulation.
PCOS attributable to Pelvic Adhesive Disease is one variety which often is associated with compromised ovarian reserve, a raised FSH blood level and ovarian resistance to fertility drugs. In many such cases, high dosage of gonadotropins (FSH-dominant) with “estrogen priming” will often elicit an ovarian response necessary for successful ovulation induction and/or IVF. Neither steroids nor Metformin are helpful in the vast majority of such cases.
PCOS women undergoing ovulation induction usually release multiple eggs following the hCG trigger and are thus at inordinate risk of twin or higher order multiple pregnancies. They are also at risk of developing OHSS. Many now believe that IVF should be regarded as a primary and preferential treatment for PCOS. The reason is that it is only through this approach that the number of embryos reaching the uterus can be controlled and in this manner the risk of high-order multiples can be minimized and it is only in the course of IVF treatment that a novel treatment method known as “prolonged coasting” ( see below) which prevents OHSS, can be implemented
SEVERE OVARIAN HYPERSTIMULATION SYNDROME (OHSS):
As indicated above, there is an inordinate propensity for women with PCOS to hyper-respond to gonadotropin fertility drugs and in the process produce large numbers of ovarian follicles. If left unchecked this can lead to OHSS, a potentially life endangering condition. The onset of OHSS is signaled by the development of a large number of ovarian follicles (usually more than 25 in number). This is accompanied by rapidly rising plasma estradiol (E2) levels, often exceeding 3000pg/ml within 7 or 9 days of stimulation, often rapidly peaking above 6,000 pg/ml prior to hCG administration. When this happens, the risk of OHSS developing is above 80%.
Symptoms and signs of OHSS include: abdominal distention due to fluid collection (ascites), fluid in the chest cavity (hydrothorax), rapid weight gain (of a pound or more per day) due to tissue fluid retention, abdominal pain, lower back ache, nausea, diarrhea, vomiting, visual disturbances such as blurred vision and spots in front of the eyes (scotomata), a rapidly declining urine output, cardiovascular collapse and failure of blood to clot which sometimes results in severe bruising (echymosis) and frank bleeding. These symptoms and signs may appear before pregnancy can be diagnosed. If pregnancy occurs, the condition is likely to worsen progressively over a period of 3-5 weeks whereupon it rapidly resolves spontaneously over a few days. If no pregnancy occurs, the symptoms and signs all disappear spontaneously within 10-12 days of the hCG injection.
When increasing fluid collection in the abdominal cavity (ascites) starts to compromise breathing raising the head of the bed rose slightly by placing a 4-6 inch block at the base of each head post and using a few additional pillows, will sometimes help ameliorate the problem. In cases where this does not help or symptoms become severe, all or most of the fluid can readily and safely be drained through t transvaginal sterile needle aspiration (vaginal paracentesis-performed once or sometimes twice a week) can be performed once or twice weekly . The problem will usually self corrects within 10-12 days of the hCG shot if pregnancy does not occur or, by the 8th week of pregnancy.
Urine output should be monitored daily to see if it drops below about 500ml a day (about two cups and a half). A chest X-ray, to evaluate for fluid collection in the chest and around the heart should be done weekly along with blood tests for hematocrit, BUN, electrolytes, creatinine, platelet count and fibrin split products (FSP). If indicated on the basis of a deteriorating clinical situation, hospitalization might be needed for close observation and if necessary, to provide intensive care.
In all case of OHSS, the ovaries will invariably be considerably enlarged. This is irrelevant to the final outcome, unless ovarian torsion (twisting of the ovary on its axis), an extremely rare complication occurs. The latter would usually require surgical emergency surgical intervention.
It is important to know that symptoms and signs of OHSS are severely aggravated by rising hCG levels. Thus such patients should not receive additional hCG injections.
Does PCOS cause poor egg/embryo quality? It is an undeniable fact that women with PCOS undergoing IVF are commonly found to have poorly developed (“dysmorphic”) eggs, with reduced fertilization potential and yielding “poor quality embryos”. However, in the author’s opinion (which admittedly runs contrary to popular opinion), this is unlikely to be due to an intrinsic deficit in egg quality. Rather, it more likely relates to intra-ovarian hormonal changes brought about by hyperstimulation and which compromise egg development. This effect, in the author’s opinion, can often be significantly reduced through implementation of an individualized or customized ovarian stimulation protocols that minimize exposure of the developing follicles and eggs to excessive LH-induced ovarian androgens. This can be best achieved by limiting the use of LH-containing gonadotropins such as Menopur through selective institution of “prolonged coasting” (see below).
In the past, the onset of OHSS, heralded by the presence of large numbers of developing ovarian follicles and rapidly rising plasma estradiol levels often led the treating physician to prematurely administer hCG in an attempt to abruptly arrest the process and prevent escalation of risk to the patient. However the premature administration of hCG, while abruptly arresting further proliferation of estrogen producing granulosa cells in the follicles, unfortunately also prematurely arrests egg development. Since the ability of an egg to achieve optimal maturation upon hCG triggering is largely predicated upon it having achieved prior optimal development, the untimely administration of hCG which triggers meiosis, probably increases the risk of numerical chromosomal abnormalities (aneuploidy) of the egg. This in turn would lead to reduced fertilization potential, poor egg/embryo quality and low embryo implantation potential.
In women with PCOS the connective tissue that surrounding the follicles (ovarian stroma) is often characteristically overgrown (stromal hyperplasia). It is the stroma that produces androgens (mainly testosterone) in response to LH. It is this, coupled with the fact that PCOS women also often have elevated blood LH concentrations (see above) results in the excessive production of androgen hormones, which is so characteristic in PCOS. While excessive exposure of developing eggs to ovarian androgens compromises follicle and egg growth it also impairs endometrial response to estrogen, which could explain the common finding of poor endometrial thickening in many PCOS women undergoing IVF.
.
The obvious remedy for these adverse effects on egg and endometrial development is to employ stimulation protocols that limit ovarian over-exposure to LH and allowing the time necessary for the follicles/eggs to develop optimally, prior to administering hCG through the judicious implementation of “Prolonged coasting” (PC).
“PROLONGED COASTING”:
In the early 90’s we were the first to report on “prolonged coasting” (PC), a novel approach that protects egg quality while preventing the development of OHSS. PC has since, gained widespread acceptance as a method of choice for preventing OHSS and has established itself as the “standard of care”. It involves withholding gonadotropin therapy while continuing the administration of the GnRHa and waiting until the plasma estradiol concentration drops below 2,500 pg/ml. Thereupon hCG is administered. In such cases, regardless of the number of developed follicles or the number of eggs retrieved, these women rarely, if ever develop OHSS. It has been reported that while PC virtually eliminates the risk of life-endangering complications associated with OHSS, there are reports in the literature that “the price to pay with PC” is often a poorer fertilization rate and reduced embryo implantation potential, compromising the pregnancy”. It is the author’s opinion an experience in the development of PC that egg/embryo quality deficit likely has little to do with the process of PC, itself and can be explained as follows: When PC is initiated too early, follicle growth and development may cease (as evidenced by the estradiol level plateauing or falling immediately, rather than showing an initial continued increase), and when PC is started too late, the follicles will often become cystic, measuring >21mm by the time the estradiol level falls below the safe threshold of 250000pg/ml, and so harbor dysmorphic eggs. Thus precise timing of the initiation of PC is critical. It should in pact be initiated preemptively in all cases when there are more than 25 follicles and the plasma estradiol reaches or exceeds 2,500pg/ml in association, provided that at least 50% of the follicles measuring 14-16mm in mean diameter. Not a day sooner or a day later. If PC is initiated with precise timing, it will usually be followed by a further progressive rise in the estradiol concentration. After a few days, the estradiol level will plateau and then it will start to fall (often rapidly). The temptation to trigger with hCG before the estradiol level falls below 3000picogtrams per milliliter must be resisted …even if the level falls below 1,000pg/ml by the time hCG is given.
Since when using agonist ( Cetrotide/Ganirelix/Orgalutron) pituitary suppression throughout the stimulation phase with gonadotropins, the plasma estradiol level often under expressed follicle growth, this method of pituitary blockade should not be used in cases ( such as with PCOS) where PC might be required.,
Prolonged coasting prevents canceled cycles and with it, canceled dreams.

Name: Crystal B
Hi Dr. Sher,
I am a 34F, underwent IVF for UI/suspected endo (I have painful periods and hyperechoic cysts, which are 1-2 occasionally, that come and go on my ovaries). I did a Gonal F protocol with Luveris, Ovidril Trigger, resulted in 2 embryos 5BB and 3BC both euploid. My 5BB natural modified failed, no implantation and am transferring my next embryo. My REI suggested for the next protocol to suppress with Lupron for 2 months and also take an anticoagulant, aspirin, antihistamine, and steroid prior to next transfer and proceed with a natural transfer (PIO to start day of transfer). Was wondering your thoughts, I do not want to do surgery as time is of the essence and worried about damaging ovarian integrity. How should I tailor my next FET for optimal success, is a natural cycle okay and what considerations should I take for my second ER if needed?
I appreciate your knowledge and loved your book. Any insight would be greatly appreciated,
Crys
Answer:
I am not in favor of natural cycle FET’s. In my opinion, it is better to pinpoint the ideal window for implantation with hormonal preparation. Here is the protocol I use:
IVF FET Protocol
Until less than a decade ago, most women undergoing IVF would have embryos transferred to the uterus in the same cycle that the egg retrieval was performed (“Fresh” Embryo Transfer). This was because embryo cryopreservation (freezing) was a hazardous undertaking. In fact, it resulted in about 30% not surviving the freezing process and those that did, having about one half the potential of “fresh embryos to implant and propagate a viable pregnancy. The main reason for the high attrition rate associated with embryo cryopreservation is that the “conventional” freezing” process that was done slowly and this resulted in ice forming within the embryo’s cells, damaging or destroying them. The introduction of an ultra-rapid cryopreservation process (vitrification) freezes the embryos so rapidly as to avoid ice crystals from developing. As a result, >90% survive the freeze/thaw process in as good a condition as they were prior to being frozen and thus without being compromised in their ability to propagate a viable pregnancy.
Recently, there have been several articles that have appeared in the literature suggest that an altered hormonal environment may be the reason for this effect. There have also been reports showing that when singletons (pregnancy with one baby) conceived naturally are compared to singletons conceived through a “fresh” embryo transfers they tend to have a greater chance of low birth weight/prematurity. This difference was not observed in babies born following FET. Hence, there is a suspicion that the altered hormonal environment during the fresh cycle may be the causative factor.
IVF Antihistamine Protocol
Available evidence suggests that FET (of pre-vitrified blastocysts) is at least as successful as is the transfer of “fresh” embryos and might even have the edge. The reason for this is certainly unlikely to have anything to do with the freezing process itself. It more than likely has to do with two factors:
- An ever increasing percentage of FET’s involve the transfer of PGS-tested, fully karyotyped, euploid blastocysts that have a greater potential to propagate viable pregnancies, than is the case with “fresh” ET’s where the embryos have rarely undergone prior PGS selection for “competency”…and,
- With targeted hormone replacement therapy for FET, one is far better able to better to optimally prepare the endometrium for healthy implantation than is the case where embryos are transferre3d following ovarian stimulation with fertility drugs.
There are additional factors other than method used for embryo cryopreservation that influence outcome following FET. These include
- An emerging trend towards selective transferring only advanced (day 5-6) embryos (blastocysts).
- (PGS) to allow for the selective transfer of genetic competent (euploid) embryos
- Addressing underlying causes of implantation dysfunction (anatomical and immunologic uterine factors) and
- Exclusive use of ultrasound guidance for delivery of embryos transferred to the uterus.
Against this background, the use of FET has several decided advantages:
- The ability to cryostore surplus embryos left over after fresh embryo transfer
- The ability to safely hold embryos over for subsequent transfer in a later frozen embryo transfer (FET) cycle (i.e. Staggered IVF) in cases where:
-
- Additional time is needed to perform preimplantation Genetic testing for embryo competency.
- In cases where ovarian hyperstimulation increases the risk of life-endangering complications associated with critically severe ovarian hyperstimulation syndrome (OHSS).
- To bank (stockpile) embryos for selective transfer of karyotypically normal embryos in older women or those who are diminished ovarian reserve
- The ability to store embryos in cases of IVF with third party parenting (Egg Donation; Gestational Surrogacy and Embryo donation) and so improve convenience for those couples seeking such services.
Preimplantation Genetic Sampling with FET:
The introduction of preimplantation genetic sampling (PGS) to karyotyping of embryos for selective transfer of the most “competent” embryos, requires in most cases that the tested blastocysts be vitribanked while awaiting test results and then transferred to the uterus at a later date. Many IVF programs have advocated the routine use of PGS in IVF purported to improve IVF outcome. But PGS should in my opinion should only be used selectively. I do not believe that it is needed for all women undergoing IVF. First there is the significant additional cost involved and second it will not benefit everyone undergoing IVF, in my opinion.
While PGS is a good approach for older women and those with diminished ovarian reserve (DOR) and also for woman who experience recurrent pregnancy loss (RPL) or “unexplained” recurrent IVF failure recent data suggests that it will not improve IVF success rates in women under 36Y who have normal ovarian reserve, who represent the majority of women seeking IVF treatment. Nor is it needed in women (regardless of their age) undergoing IVF with eggs donated by a younger donor. This is because in such women about 1:2/3 of their eggs/embryos are usually chromosomally normal, and in most cases will upon fertilization produce multiple blastocysts per IVF attempt, anyway. Thus in such cases the transfer of 2 blastocysts will likely yield the same outcome regardless of whether the embryos had been subjected to PGS or not. The routine use of
It is another matter when it comes to women who have diminished ovarian reserve and/or DOR contemplating embryo banking and for women with unexplained recurrent IVF failure, recurrent pregnancy loss and women with alloimmune implantation dysfunction who regardless of their age or ovarian reserve require PGS for diagnostic reasons.
Embryo Banking: Some IVF centers are doing embryo banking cycles with Preimplantation Genetic Screening (PGS). With Embryo Banking” several IVF cycles are performed sequentially (usually about 2 months apart), up to the egg retrieval stage. The eggs are fertilized and the resulting advanced embryos are biopsied. The biopsy specimens are held over until enough 4-8 blastocysts have been vitribanked, thus providing a reasonable likelihood that one or more will turn out to be PGS-normal. At this point the biopsy specimens (derived all banking cycles) are sent for PGS testing at one time (a significant cost-saver), the chromosomally normal blastocysts are identified and the women are scheduled for timed FET procedures….. with a good prospect of a markedly improved chance of success as well as a reduced risk of miscarriage.
Standard (proposed) Regimen for preparing the uterus for frozen embryo transfer FET) is as follows:
The recipient’s cycle is initiated with an oral contraceptive-OC (e.g. Marvelon/Lo-Estrin; Lo-Ovral etc) for at least 10 days. This is later overlapped with 0.5 mg. (10 units) Lupron/Lucrin (or Superfact/Buserelin) daily for 3 days. Thereupon the OC is withdrawn and daily 0.25 mg (5 units) of Lupron/Lucrin/Superfact injections are continued. Menstruation will usually ensue within 1 week. At this point, an ultrasound examination is performed to exclude ovarian cyst(s) and a blood estradiol measurement is taken (it needs to be <70pg/ml) until daily progesterone administration is initiated some time later. The daily Lupron/Lucrin/Superfact is continued until the initiation of progesterone therapy (see below).
Four milligram (4mg) Estradiol valerate (Delestrogen) IM is injected SC, twice weekly (on Tuesday and Friday), commencing within a few days of Lupron/Lucrin/Superfact-induced menstruation. Blood is drawn on Monday and Thursday for measurement of blood [E2]. This allows for planned adjustment of the E2V dosage scheduled for the next day. The objective is to achieve a plasma E2 concentration of 500-1,000pg/ml and an endometrial lining of >8mm, as assessed by ultrasound examination done after 10 days of estrogen exposure i.e. a day after the 3rd dosage of Delestrogen.. The twice weekly, final (adjusted) dosage of E2V is continued until pregnancy is discounted by blood testing or an ultrasound examination. Dexamethasone 0.75 mg is taken orally, daily with the start of the Lupron/Lucrin/Superfact. Oral folic acid (1 mg) is taken daily commencing with the first E2V injection and is continued throughout gestation. Patients also receive Ciprofloxin 500mg BID orally starting with the initiation of Progesterone therapy and continuing for 10 days.
Luteal support commences 6 days prior to the ET, with intramuscular progesterone in oil (PIO) at an initial dose of 50 mg (P4-Day 1). Starting on progesterone administration-Day 2, PIO is increased to 100 mg daily continuing until the 10th week of pregnancy, or until a blood pregnancy test/negative ultrasound (after the 6-7th gestational week), discounts a viable pregnancy.
Also, commencing on the day following the ET, the patient inserts one (1) vaginal progesterone suppository (100 mg) in the morning + 2mg E2V vaginal suppository (in the evening) and this is continued until the 10th week of pregnancy or until pregnancy is discounted by blood testing or by an ultrasound examination after the 6-7th gestational week. Dexamethasone o.75mg is continued to the 10th week of pregnancy (tailed off from the 8th to 10th week) or as soon as pregnancy is ruled out. With the obvious exception of the fact that embryo recipients do not receive an hCG injections, luteal phase and early pregnancy hormonal support and immuno-suppression is otherwise the same as for conventional IVF patients. Blood pregnancy tests are performed 13 days and 15 days after the first P4 injection was given.
Note: One (1) vaginal application of Crinone 8% is administered on the 1st day (referred to as luteal phase day 0 – LPO). On LP Day 1, they will commence the administration of Crinone 8% twice daily (AM and PM) until the day of embryo transfer. Withhold Crinone on the morning of the embryo transfer and resume Crinone administration in the PM. Crinone twice daily is resumed from the day after embryo transfer. Contingent upon positive blood pregnancy tests, and subsequently upon the ultrasound confirmation of a viable pregnancy, administration of Crinone twice daily are continued until the 10th week of pregnancy.
Regime for Thawing and Transferring Cryopreserved Embryos/Morulae/Blastocysts:
Patients undergoing ET with cryopreserved embryos/morulas/blastocysts will have their embryos thawed and transferred by the following regimen.
Day 2 (P4) | Day 6 (P4) | |
PN | Thaw | ET |
Day 3 Embryo | ET | |
Blastocysts frozen on day 5 post-ER | FET | |
Blastocysts frozen on day 6, post-ER | FET
|

Dear Dr. Sher,
I am 39 years old and I was hoping to do a frozen embryo transfer. I have two genetically healthy and high quality frozen embryos. I was set to start the transfer process in mid-July and wanted to consult a different doctor, who suspected adenomyosis and recommended a shot a week before my period starts. I wanted to get a second opinion about what to do in this case and also ask about the risks/percentages of miscarriage as well as implantation success rates with patients with adenomyosis. My periods have always been regular and with no pain and up until this last ultrasound, my previous doctors had not suspected anything. I did have a uterine polyp removed in mid-September. I wonder if this is something that can develop quickly or if it was missed by others.
Thanks so much in advance for your concern.
Melis Taner
Answer:
Adenomyosis is a condition where endometrial glands develop outside the uterine lining (endometrium), within the muscular wall of the uterus (myometrium). Definitive diagnosis of adenomyosis is difficult to make. The condition should be suspected when a premenopausal woman (usually>25 years of age) presents with pelvic pain, heavy painful periods, pain with deep penetration during intercourse, “unexplained infertility” or repeated miscarriages and thereupon, when on digital pelvic examination she is found to have an often smoothly enlarged (bulky) soft tender uterus. Previously, a definitive diagnosis was only possible after a woman had her uterus removed (hysterectomy) and it this was inspected under a microscope. However the use of uterine magnetic resonance imaging (MRI) now permits reliable diagnosis. Ultrasound examination of the uterus on the other hand , while not permitting definitive diagnosis, is a very helpful tool in raising a suspicion of the existence of adenomyosis.
Criteria used to make a diagnosis of adenomyosis on transvaginal ultrasound:
- Smooth generalized enlargement of the uterus.
- Asymmetrical thickening of one side of the (myometrium) as compared to another side.
- Thickening (>12mm) of the junctional zone between the endometrium and myometrium with increased blood flow.
- Absence of a clear line of demarcation between the endometrium and the myometrium
- Cysts in the myometrium
- One or more non discrete (not encapsulated) tumors (adenomyomas) in the myometrium.
Since there is no proven independent relationship between adenomyosis and egg/embryo quality any associated reproductive dysfunction (infertility/miscarriages) might be attributable to an implantation dysfunction. It is tempting to postulate that this is brought about by adenomyosis-related anatomical pathology at the endometrial-myometrial junction. However, many women with adenomyosis, do go on to have children without difficulty. Given that 30%-70% of women who have adenomyosis also have endometriosis…. a known cause of infertility, it is my opinion that infertility caused by adenomyosis is likely linked to endometriosis where infertility is at least in part due to a toxic pelvic environment that compromises egg fertilization potential and/or due to an immunologic implantation dysfunction (IID) linked to activation of uterine natural killer cells (NKa). Thus, in my opinion all women who are suspected of having adenomyosis-related reproductive dysfunction (infertility/miscarriages) should be investigated for endometriosis and for IID. The latter, if confirmed would make them candidates for selective immunotherapy (using intralipid/steroid/heparin) in combination with IVF.
Surgery: Conservative surgery to address adenomyosis-related infertility involves excision of portions of the uterus with focal or nodular adenomyosis and/or excision of uterine adenomyomas. It is very challenging and difficult to perform because adenomyosis does not have distinct borders that distinguish normal uterine tissue from the lesions. In addition, surgical treatment for adenomyosis-related reproductive dysfunction is of questionable value and of course is not an option for diffuse adenomyosis.
Medical treatment: There are three approaches.
- GnRH agonists (Buserelin/Lupron) which is thought to work by lowering estrogen levels.
- Aromatase inhibitors such as Letrozole have also been tried with limited success
- Inhibitors of angiogenesis: The junctional zone in women with adenomyosis may grow blood vessels more readily that other women (i.e. angiogenesis). A hormone known as VEGF can drive this process. It is against this background that it has been postulated that use of drugs that reduce the action of VEGF and thereby counter blood vessel proliferation in the uterus could have a therapeutic benefit. While worth trying in some cases, thus far such treatment has been rather disappointing
- Immunotherapy to counter IID: The use of therapies such as Intralipid (or IVIG)/steroids/heparin in combination with IVF might well hold promise in those women with adenomyosis who have NKa.
Fortunately, not all women with adenomyosis are infertile. For those who are, treatment presents a real problem. Even when IVF is used and the woman conceives, there is still a significant risk of miscarriage. Since the condition does not compromise egg/embryo quality, women with adenomyosis-related intractable reproductive dysfunction who fail to benefit from all options referred to above…(including IVF) might as a last resort consider Gestational surro resort consider Gestational surrogacy.

Answer:
The journey of in vitro fertilization can be a rollercoaster of emotions for many patients. Often times they have to face the harsh reality that the number and quality of eggs retrieved has fallen short of their expectations. Then, should fertilization of these eggs not propagate chromosomally normal (euploid), “competent” embryos suitable for transfer to the uterus, many such patients find themselves in a state of emotional distress. They grapple with the inevitable questions of why this happened and how to prevent it from occurring again in the future. This article aims to delve into these queries, providing insights, rational explanations, and therapeutic options. It is an invitation to explore the light at the end of the tunnel. Readers are urged to carefully absorb the entirety of the article in the hope of finding valuable information and renewed hope.
- The Importance of Chromosomal Integrity: While sperm quality is an important factor, egg quality is by far the most important when it comes to the generation of embryos that are capable of propagating healthy babies (“competent”). In this regard, chromosomal integrity of the egg and embryo, although it is not the only factor , is certainly the main determinant of such competency.
- The woman’s age: About two thirds of a woman’s eggs in her twenties or early thirties have the correct number of chromosomes, which is necessary for a healthy pregnancy. As a woman gets older, the percentage of eggs with the right number of chromosomes decreases. By age 40, only about one in every 5-6 eggs is likely to be normal, and by the mid-forties, less than one in ten eggs will be normal.
- Ovarian Reserve (number of available in the ovaries): A woman is born with all the eggs she will ever have. She starts using these eggs when she begins ovulating during puberty. At first, the eggs are used up quickly, but as she gets older, the number of eggs starts to run out. Her brain and pituitary gland try to stimulate the production of more eggs by increasing the output of Follicle Stimulating Hormone (FSH), but unfortunately, this often doesn’t work. When the number of remaining eggs in her ovaries falls below a certain level (which can be different for each woman), her FSH level rises, and production of the ovarian hormone, AMH decreases. This is the start of diminishing ovarian reserve (DOR). Most women experience the onset of DOR in their late 30s or early 40s, but it can happen earlier for some. The lower the ovarian reserve, the lower the AMH level will be, and the fewer eggs will be available for harvesting during IVF-egg retrieval. In such cases, a higher dosage of fertility drugs might be needed to promote better egg production in future attempts. . On the other hand, higher AMH levels mean more eggs are available, and lower doses of fertility drugs are usually needed. DOR is commonly associated with increased bioactivity of pituitary gland-produced LH. This LH activates production of ovarian male hormones (androgens)…predominantly testosterone by ovarian connective tissue (stroma) . While a small amount of ovarian testosterone is absolutely necessary for optimal follicle and egg development, excessive ovarian testosterone will often access the follicle , and compromise both egg quality and follicle growth and development. In some cases, rapidly increasing LH-release (“premature LH-surge”) with excessive induced ovarian testosterone can lead to “premature luteinization” of the follicles with cessation in growth and even to“ premature ovulation”.
- Importance of Individualized Controlled Ovarian Stimulation (COS) Protocol: It’s not surprising that DOR is more common in older women, but regardless of age, having DOR makes a woman’s eggs more likely to be compromised during controlled ovarian stimulation (COS). The choice of the COS protocol is crucial to preventing unintentional harm to egg and embryo quality. The wrong protocol can disrupt normal egg development and increase the risk of abnormal embryos. That’s why it’s important to tailor the COS protocol to each individual’s needs. This helps optimize follicle growth and the quality of eggs and embryos. The timing of certain treatments is also important for successful outcomes.
- Embryo Competency and Blastocyst Development: Embryos that don’t develop into blastocysts by day 6 after fertilization are usually chromosomally abnormal or aneuploid (”incompetent”) and not suitable for transfer. However, not all blastocysts are guaranteed to be normal and capable of developing into a healthy baby. As a woman gets older, the chances of a her embryos being chromosomally normal blastocyst decreases. For example, a blastocyst from a 30-year-old woman is more likely to be normal compared to one from a 40-year-old woman.
The IVF stimulation protocol has a big impact on the quality of eggs and embryos especially in women with DOR. Unfortunately, many IVF doctors use the same COS “recipe approach” for everyone without considering individual differences. Using personalized protocols can greatly improve the success of IVF. While we can’t change genetics or reverse a woman’s age, a skilled IVF specialist can customize the COS protocol to meet each patient’s specific needs.
GONADOTROPIN RELEASING HORMONE AGONISTS (GNRHA) AND GNRH-ANTAGONISTS:
- Gonadotropin releasing hormone agonists (GnRHa). Examples are Lupron, Buserelin, Superfact, and Decapeptyl . These are commonly used to launch ovarian stimulation cycles. They work by initially causing a release of pituitary gonadotropins, followed by a decrease in LH and FSH levels within 4-7 days. This creates a relatively low LH environment when COS begins, which is generally beneficial for egg development. However, if GnRHa are administered starting concomitant with gonadotropin stimulation (see GnRHa –“flare protocol” -below) it can cause an immediate surge in LH release, potentially leading to high levels of ovarian testosterone that can harm egg quality, especially in older women and those with diminished ovarian reserve (DOR).
- Gonadotropin releasing hormone antagonists (GnRH-antagonists) : Examples are Ganirelix, Cetrotide, and Orgalutron. GnRH antagonists (take days work quickly (within hours) to block pituitary LH release. Their purpose is to prevent excessive LH release during COS. In contrast, the LH-lowering effect of GnRH agonists takes several days to develop. Traditionally, GnRH antagonists are given starting on the 5th-7th day of gonadotropin stimulation. However, in older women and those with DOR, suppressing LH might happen too late to prevent excessive ovarian androgen production that can negatively impact egg development in the early stages of stimulation. That’s why I prefer to administer GnRH-antagonists right from the beginning of gonadotropin administration.
USING BIRTH CONTROL PILLS TO START OVARIAN STIMULATION:
Patients are often told that using birth control pills (BCP) to begin ovarian stimulation will suppress the response of the ovaries. This is true, but only if the BCP is not used correctly. Here’s the explanation:
In natural menstrual cycles and cycles stimulated with fertility drugs, the follicles in the ovaries need to develop receptors that respond to follicle-stimulating hormone (FSH) in order to properly respond to FSH stimulation. Pre-antral follicles (PAFs) do not have these receptors and cannot respond to FSH stimulation. The development of FSH responsivity requires exposure of the pre-antral follicles to FSH for several days, during which they become antral follicles (AFs) and gain the ability to respond to FSH-gonadotropin stimulation. In regular menstrual cycles, the rising FSH levels naturally convert PAFs to AFs. However, the combined BCP suppresses FSH. To counter this suppression, we need to promote increased FSH production several days before starting COS. This allows the orderly conversion from PAFs to AFs, ensuring proper follicle and egg development.
GnRHa causes an immediate surge in FSH release by the pituitary gland, promoting the conversion from PAF to AF. Therefore, when women take the BCP control pill to launch a cycle of COS, they need to overlap the BCP with a GnRHa for a few days before menstruation. This allows the early recruited PAFs to complete their development and reach the AF stage, so they can respond appropriately to ovarian stimulation. By adjusting the length of time, the woman is on the birth control pill, we can regulate and control the timing of the IVF treatment cycle. Without this step, initiating ovarian stimulation in women coming off birth control pills would be suboptimal.
PROTOCOLS FOR CONTROLLED OVARIAN STIMULATION (COS):
- GnRH Agonist Ovarian Stimulation Protocols:
- The long GnRHa protocol: Here, a GnRHa (usually Lupron or Superfact) is given either in a natural cycle, starting 5-7 days before menstruation, overlapping with the BCP for three days. Thereupon, the pill is stopped, while daily GnRHa injections continue until menstruation occurs (usually 5-7 days later). The GnRHa causes a rapid rise in FSH and LH levels. This is followed about 3-4 days later , by a progressive decline in FSH and LH to near zero levels, with a concomitant drop in ovarian estradiol and progesterone. This, in turn triggers uterine withdrawal bleeding (menstruation) within 5-7 days of starting the GnRHa administration. Gonadotropin treatment is then initiated while daily GnRHa injections continue to maintain a relatively low LH environment. Gonadotropin administration continues until the hCG “trigger” (see below).
- Short GnRH-Agonist (“Flare”) Protocol: This protocol involves starting hormone therapy and using GnRH agonist at the same time. The goal is to boost FSH so that with concomitant stimulation with FSH-gonadotropins + the GnRHa-induced surge in pituitary gland FSH release, will augment follicle development. However, this surge also leads to a rise in LH levels, which can cause an excessive production of ovarian male hormones (e.g., testosterone). This could potentially adversely affect the quality of eggs, especially in women over 39 years old, those with low ovarian reserve, and women with PCOS or DOR who already have increased LH sensitivity. In this way, these “flare protocols” can potentially decrease the success rates of IVF. While they are generally safe for younger women with normal ovarian reserve, I personally avoid using this approach on the off chance that even patients with normal ovarian reserve, might experience poor egg quality.
- GnRH Antagonist-Ovarian Stimulation Protocols:
- Conventional GnRH Antagonist Protocol: In this approach, daily GnRH antagonist injections are given from the 5th to the 8th day of COS with gonadotropins to the day of the “trigger” (see below). Accordingly, although rapidly acting to lower LH , this effect of GnRH- antagonist only starts suppressing LH from well into the COS cycle which means the ovarian follicles are left exposed and unshielded from pituitary gland -produced, (endogenous) LH during the first several days of stimulation. This can be harmful, especially in the early stage of COS when eggs and follicles are most vulnerable to the effects of over-produced LH-induced excessive ovarian testosterone. Therefore, I believe the Conventional GnRH Antagonist Protocol is not ideal for older women, those with low ovarian reserve, and women with PCOS who already have elevated LH activity. However, this protocol is acceptable for younger women with normal ovarian reserve, although I personally avoid using this approach on the off chance that even patients with normal ovarian reserve, might experience poor egg quality.
It’s important to note that the main reason for using GnRH antagonists is to prevent a premature LH surge, which is associated with poor egg and embryo quality due to follicular exhaustion. However, calling it a “premature LH surge” is misleading because it actually represents the culmination of a progressive increase in LH-induced ovarian testosterone. A better term would be “premature luteinization”. In some such cases, the rise in LH can precipitate “premature ovulation”.
- Agonist/Antagonist Conversion Protocol (A/ACP): I recommend this protocol for many of my patients, especially for older women and those with DOR or PCOS. The woman starts by taking a BCP for 7-10 days. This overlapped with a GnRHa for 3 days and continued until menstruation ensues about 5-7 days later. At this point she “converts” from the GnRH-agonist to a GnRH-antagonist (Ganirelix, Orgalutron, or Cetrotide). A few days after this conversion from agonist to antagonist, COS with gonadotropin stimulation starts. Both the antagonist and the gonadotropins are continued together until the hCG trigger. The purpose is to suppress endogenous LH release throughout the COS process and so avoid over-exposure of follicles and eggs to LH-induced excessive ovarian testosterone which as previously stated, can compromise egg and follicle growth and development. Excessive ovarian testosterone can also adversely affect estrogen-induced growth of the uterine lining (endometrium). Unlike GnRH-agonists, antagonists do not suppress ovarian response to the gonadotropin stimulation. This is why the A/ACP is well-suited for older women and those with diminished ovarian reserve.
- A/ACP with estrogen priming: This is a modified version of the A/ACP protocol used for women with very low ovarian reserve (AMH=<0.2ng/ml). Estrogen priming is believed to enhance the response of follicles to gonadotropins. Patients start their treatment cycle by taking a combined birth control pill (BCP) for 7-10 days. After that, they overlap daily administration of a GnRH agonist with the BCP for 3 days. The BCP is then stopped, and the daily agonist continues until menstruation ensues (usually 5-7 days later). At this point, the GnRH agonist is supplanted by daily injections of GnRH antagonist and Estradiol (E2) “priming” begins using E2 skin patches or intramuscular estradiol valerate injections twice weekly, while continuing the GnRH antagonist. Seven days after starting the estrogen priming COS begins using recombinant FSHr such as Follistim, Gonal-F or Puregon) +menotropin (e.g., Menopur) . The estrogen “priming” continues to the day of the “trigger” (see below). Egg retrieval is performed 36 hours after the trigger.
Younger women (under 30 years) and women with absent, irregular, or dysfunctional ovulation, as well as those with polycystic ovarian syndrome (PCOS), are at risk of developing a severe condition called Ovarian Hyperstimulation Syndrome (OHSS), which can be life-threatening. To predict this condition, accurate daily blood E2 level monitoring is required.
TRIGGERING “EGG MATURATION PRIOR TO EGG RETRIEVAL”
- The hCG “trigger”: When it comes to helping eggs mature before retrieval, one of the important decisions the doctor needs to make is choosing the “trigger shot” to facilitate the process. Traditionally, hCG (human chorionic gonadotropin) is derived from the urine of pregnant women (hCGu) while a newer recombinant hCG (hCGr), Ovidrel was recently The ideal dosage of hCGu is 10,000U and for Ovidrel, the recommended dosage is 500mcg. Both have the same efficacy. The “trigger” is usually administered by intramuscular injection, 34-36 hours prior to egg retrieval.
Some doctors may choose to lower the dosage of hCG if there is a risk of severe ovarian hyperstimulation syndrome (OHSS). However, I believe that a low dose of hCG (e.g., 5000 units of hCGu or 250 mcg of hCGr ( Ovidrel) might not be enough to optimize egg maturation, especially when there are many follicles. Instead, I suggest using a method called “prolonged coasting” to reduce the risk of OHSS.
- Using GnRH antagonist alone or combined with hCG as the trigger: Some doctors may prefer to use a GnRH- agonist trigger instead of hCG to reduce the risk of OHSS. The GnRHa “trigger” acts by inducing a “surge of pituitary gland-LH. However, it is difficult to predict the amount of LH that is released in response to a standard agonist trigger. In my opinion, using hCG is a better choice, even in cases of ovarian hyperstimulation, with the condition that “prolonged coasting” is implemented beforehand.
- Combined use of hCG + GnRH agonist: This approach is better than using a GnRH agonist alone but still not as effective as using the appropriate dosage of hCG.
- Timing of the trigger: The trigger shot should be given when the majority of ovarian follicles have reached a size of more than 15 mm, with several follicles measuring 18-22 mm. Follicles larger than 22 mm often contain overdeveloped eggs, while follicles smaller than 15 mm usually have underdeveloped and potentially abnormal eggs.
SEVERE OVARIAN HYPERSTIMULATION SYNDROME (OHSS) & “PROLONGED COASTING”
OHSS is a life-threatening condition that can occur during controlled ovarian stimulation (COS) when the blood E2 (estradiol) level rises too high. It is more common in young women with high ovarian reserve, women with polycystic ovarian syndrome (PCOS), and young women who do not ovulate spontaneously. To prevent OHSS, some doctors may trigger egg maturation earlier, use a lower dosage of hCG, or “trigger” using a GnRHa. However, these approaches can compromise egg and embryo quality and reduce the chances of success.
To protect against the risk of OHSS while optimizing egg quality, Physicians can use one of two options. The first is “prolonged coasting,” a procedure I introduced more than three decades ago. It involves stopping gonadotropin therapy while continuing to administer the GnRHa until the risk of OHSS has decreased. The precise timing of “prolonged coasting” is critical. It should be initiated when follicles have reached a specific size accompanied and the blood estradiol has reached a certain peak. The second option is to avoid fresh embryo transfer and freeze all “competent” embryos for later frozen embryo transfers (FETs) at a time when the risk of OHSS has subsided. By implementing these strategies, both egg/embryo quality and maternal well-being can be maximized.
In the journey of fertility, a woman is blessed with a limited number of eggs, like precious treasures awaiting their time. As she blossoms into womanhood, these eggs are gradually used, and the reserves start to fade. Yet, the power of hope and science intertwines, as we strive to support the development of these eggs through personalized treatment. We recognize that each woman is unique, and tailoring the protocol to her individual needs can unlock the path to success. We embrace the delicate timing, understanding that not all embryos are destined for greatness. With age, the odds may shift, but our dedication remains steadfast, along with our ultimate objective, which is to do everything possible to propagate of a normal pregnancy while optimizing the quality of that life after birth and all times, minimizing risk to the prospective parents.

Name: Barby S
I had an FET. My two weeks blood test was positive with hcg of 3146 miu/ml and 218nmol/l progesterone.
Two days after I repeaters this test and hcg had risen to 4845 miy/ml but progesterone dropped substantially to 48.8 nm/l.
Is this a cause for concerned. I am really stressing about the progesterone levels even though I am taken supplements.
Answer:
I think you probably are OK but, in my opinion, you should do an ultrasound to determine fetal viability and growth. Then do another hCG blood test and repeat the US in 1 week.
Going through IVF is a major investment, emotionally, physically, and financially, for every patient or couple. One of the most crucial moments is receiving the result of the blood test for human chorionic gonadotropin (hCG) pregnancy. It’s a big deal! The days after the embryo transfer, waiting for this result, can be extremely stressful. That’s why it’s crucial for the IVF doctor and staff to handle this information with care and professionalism. They should be accessible to the patient/couple and provide results promptly and sensitively.
Testing urine or blood to check for human chorionic gonadotropin (hCG) is the best way to confirm pregnancy. Urine tests are cheaper and more commonly used. They are also more convenient because they can be done anywhere. However, blood tests are more reliable and sensitive than urine tests. They can detect pregnancy earlier and at lower hCG levels. Blood tests are also more accurate and can track changes in hCG levels over time. Urine tests can detect hCG when blood levels are above 20IU, which is about 16-18 days after ovulation or 2-3 days after a missed period. Blood tests can measure any concentration of hCG about 12-13 days after ovulation.
Detecting hCG in the blood early on and tracking its increase is especially useful for women undergoing fertility treatments like controlled ovarian stimulation or in vitro fertilization. The sooner hCG is detected and measured, the more information can be gathered about the success of implantation and the health of the developing embryo.
Typically, two beta hCG blood tests are done, spaced 2-4 days apart. It’s best to wait for the results of the second test before reporting on the pregnancy. This is because an initial result can change, even from equivocal or negative to positive. Sometimes a normal embryo takes longer to implant, and the hCG level can be initially low or undetectable. Regardless of the initial level, the test should be repeated after two days to check for a significant rise in hCG. A significant rise usually indicates that an embryo is implanting, which suggests a possible pregnancy. Waiting for the second test result helps avoid conveying false hope or disappointment.
It’s important to note that beta hCG levels don’t double every two days throughout pregnancy. Once the levels rise above 4,000U, they tend to increase more slowly. Except in specific cases like IVF using an egg donor or transfer of genetically tested embryos, the birth rate following IVF in younger women is around 40% per embryo transfer. Patients need to have realistic expectations and should be informed about how and when they will receive the news, as well as counseling in case of a negative outcome.
When an embryo starts to implant, it releases the pregnancy hormone hCG into the woman’s bloodstream. Around 12 days after egg retrieval, 9 days after a day 3 embryo transfer, or 7 days after a blastocyst transfer, a woman should have a quantitative beta hCG blood pregnancy test performed. By that time, most of the hCG injected to prepare the eggs for retrieval should have cleared from the bloodstream. So, if the test detects more than 10 IU of hCG per ml of blood, it indicates that the embryo has attempted to implant. In third-party IVF (e.g., ovum donation, gestational surrogacy, embryo adoption, or frozen embryo transfers), no hCG trigger is administered, so any amount of hCG detected in the blood is considered significant.
Sometimes, there is a slow initial rise in hCG between the first and second tests (failure to double every 48 hours). In such cases, a third and sometimes a fourth hCG test should be done at two-day intervals. A failure to double on the third and/or fourth test is a poor sign and could indicate a failed or dysfunctional implantation. In some cases, a progressively slow rising hCG level might indicate an ectopic pregnancy, which requires additional testing and follow-up.
In certain situations, the first beta hCG level starts high, drops with the second test, and then starts doubling again. This could suggest that initially, multiple embryos started to implant but only one survived to continue a healthy implantation.
It’s customary for the IVF clinic staff to inform the patient/couple and the referring physician about the hCG pregnancy test results. Often, the IVF physician or nurse-coordinator coordinates with the referring physician to arrange all necessary pregnancy tests. If the patient/couple prefer to make their own arrangements, the program should provide detailed instructions.
In some cases, when the two blood pregnancy tests show that one or more embryos are implanting, certain programs recommend daily injections of progesterone or the use of vaginal hormone suppositories for several weeks to support the implantation process. Others give hCG injections three times a week until the pregnancy can be confirmed by ultrasound examination. Some IVF programs don’t prescribe any hormones after the embryo transfer.
Patients with appropriate doubling of hCG levels within two days after frozen embryo transfer (FET) or third-party IVF procedures such as surrogacy or egg donation may receive estradiol and progesterone injections, often along with vaginal hormone suppositories, for 10 weeks after the implantation is diagnosed by blood pregnancy testing.
A positive Beta hCG blood pregnancy test indicates the possibility of conception, but ultrasound confirmation is needed to confirm the pregnancy. Until then, it is referred to as a “chemical pregnancy.” Only when ultrasound examination confirms the presence of a gestational sac, clinical examination establishes a viable pregnancy, or after abortion when products of conception are detected, is it called a clinical intrauterine pregnancy.
A significantly elevated hCG blood level without concomitant detection of an gestational sac inside the uterus by ultrasound after 5 weeks gestation raises the suspicion of an ectopic (tubal) pregnancy.
The risk of miscarriage gradually decreases once a viable clinical pregnancy is diagnosed (a conceptus with a regular heartbeat of 110-180 beats per minute). From this point onward, the risk of miscarriage is usually 10- 15% for women under 40 years old and around 35% for women in their early forties.
Dealing with successful IVF cases is relatively easy as everyone feels happy and validated. The real challenge lies in handling unsuccessful cases. Setting rational expectations from the beginning is crucial. In some cases (fortunately rare), emotional pressure may overwhelm the patient/couple, leading to a need for counseling or psychiatric therapy. I always advise my patients that receiving optimal care doesn’t always guarantee the desired outcome. There are many variables beyond our control, especially the unpredictable nature of fate. With around 36 years of experience in this field, I strongly believe that when it comes to IVF, the saying “man proposes while God disposes” always holds.
There are a few important things to consider when interpreting blood hCG levels. Levels can vary widely, ranging from 5mIU/ml to over 400mIU/ml, 10 days after ovulation or egg retrieval. The levels double every 48-72 hours until the 6th week of pregnancy, after which the doubling rate slows down to about 96 hours. By the end of the 1st trimester, hCG levels reach 13,000-290,000 IU and then slowly decline to around 26,000-300,000 IU at full term. Here are the average hCG levels during the first trimester:
- 3 weeks after the last menstrual period (LMP): 5-50 IU
- 4 weeks LMP: 5-426 IU
- 5 weeks LMP: 18-7,340 IU
- 6 weeks LMP: 1,080-56,500 IU
- 7-8 weeks LMP: 7,650-229,000 IU
- 9-12 weeks LMP: 25,700-288,000 IU
Most doctors wait until around the 7th week to perform an ultrasound to confirm pregnancy. By that time, the heartbeat should be clearly visible, providing a more reliable assessment of the pregnancy’s viability.
In some cases, blood hCG levels can be unusually high or increase faster than normal. This could indicate multiple pregnancies or a molar pregnancy. Rarely, conditions unrelated to pregnancy, such as certain ovarian tumors or cancers, can cause detectable hCG levels in both blood and urine.
To summarize, testing urine or blood for hCG is the most reliable way to confirm pregnancy. Urine tests are more common and convenient, while blood tests are more accurate and can detect pregnancy earlier. Tracking hCG levels in the blood is especially important for women undergoing fertility treatments. It’s essential to wait for the results of a second blood test before confirming pregnancy to avoid false hope or disappointment. Interpreting hCG levels requires considering various factors, and doctors usually perform an ultrasound around the 7th week for a more accurate assessment. Unusually high hCG levels may indicate multiple pregnancies or other conditions unrelated to pregnancy. Providing sensitive and timely communication of results is crucial for IVF clinics to support patients through the emotional journey.

Name: Sahar S
Hi Dr Sher
I recently completed my first cycle of IVF in Australia and both FET failed. The first one in Feb was a chemical pregnancy, and the second one last month did not even detect any hcg in my blood.
I have secondary infertility, conceived my first bub 6 years ago without trying and no issues. She was born at 37 weeks/
I have completed all necessary bloods, ultrasounds, etc and nothing has come up. Been told by my FS that everything is normal.
My twin sis was on clexane and her FET worked. I asked my FS about clexane and she won’t prescribe as she feels I don’t need it.
Are there more tests I can do before we start our second cycle? Or is there any general advice you would offer? Thank you
Answer:
a) It is one thing for a woman who has never been able to conceive (primary infertility) to come to grips with undergoing In Vitro Fertilization. It is quite another matter for someone who has successfully achieved a pregnancy in the past having to come to terms with a subsequent inability to conceive (secondary infertility). When this happens, it raises issues of guilt, a declining sense of self-worth and ultimately self-recrimination. The ramifications often impact family relationships involving partners and siblings. The truth is that secondary infertility can be just as difficult for individuals and family to deal with as primary infertility.
There are many factors that contribute to the problem of secondary infertility. These include:
Social and marital factors: In this modern day and age where at least one in two marriages ends in divorce, it is not surprising that there would be an inevitable hiatus in childbearing. This often results in a considerable delay in re-initiating family building. Since the biological clock keeps on ticking in the interim, advancing age can, and often does, have a profound affect on a woman’s ability to subsequently conceive and successfully complete a pregnancy. In my experience, this is one of the most common reasons for secondary infertility. In addition, by the time a decision is made to enter a new relationship, many men and women will have undergone a prior sterilization procedure which now needs to be addressed. To make matters worse, many such men and women first opt for surgical reversal of their occlusive surgery, only to learn in the end that the procedures were not successful, and they now need to consider in vitro fertilization (IVF) in one form or another.
Financial factors: Here, the cost of raising a child often weighs heavily, especially in this present tough economic climate. This is becoming more of an issue as women playing an ever increasing role as a primary bread winner.
Career demands: There can be little doubt that when it comes to climbing the career ladder, women are considerably disadvantaged by the fact that pregnancy and the immediate demands of child rearing take away from their ability to compete with men. As such, many women choose to delay having another child until such time as they have been able to make up for prior lost opportunity.
Medical barriers to fertility: Certain common medical conditions, while not absolutely precluding pregnancy, make it much more difficult to conceive.
Endometriosis: It is not uncommon for women with endometriosis to achieve a pregnancy, but find difficulty in doing so again at a later date. The reason for this is that while most women with endometriosis have patent fallopian tubes, the environment surrounding their tubes is compromised due to pelvic toxins that are produced by the endometriotic implants. These toxins compromise egg fertilization potential, making it more difficult for sperm in the fallopian tube to fertilize the egg upon its arrival there. As such, endometriosis is one of the commonest causes of secondary infertility.
Tubal damage due to prior pelvic inflammatory disease: In first world countries, the early and often indiscriminate use of antibiotics for the slightest symptom has led to the point where an acute attack of pelvic inflammatory disease is often masked. As such, less than 30% of American women with tubal damage have knowledge that their tubes are compromised and that they might have subsequent difficulty in conceiving. Since, in many such cases the tubal damage will not have totally blocked both tubes, some of the women so affected might experience a pregnancy but have difficulty in conceiving again later down the line.
Dysfunctional ovulation: Since ovulation as well as normal hormonal support of the early implanting embryo are both essential for a healthy pregnancy to occur, it follows that women with irregular or dysfunctional ovulation (e.g., polycystic ovarian syndrome – PCOS, persistent follicular luteal phase deficiencies or post birth control pill ovulatory problems) might sporadically conceive and thereupon find it difficult to do achieve another pregnancy later on.
Immunologic Implantation Dysfunction (IID): has become ever more apparent that immunologic factors play an important role in achieving healthy implantation. Women with endometriosis (regardless of its severity), those with a personal or family history of autoimmune diseases such as lupus erythematosus, rheumatoid arthritis and thyroid autoimmunity (TAI), and some cases where the man and the woman share certain genetic similarities (alloimmune implantation dysfunction), will have activated CTL/NK cells that can inhibit or compromise healthy implantation. This is an often overlooked cause of secondary infertility. Most such autoimmune/alloimmune cases require selective immunotherapy and IVF.
Antisperm Antibodies: Although infrequent, some cases of secondary infertility might also be caused by the woman harboring antisperm antibodies. In such cases IVF is mandated.
Previous post-pregnancy uterine infection: Retention of products of conception after the birth of a child, miscarriage, or abortion can so damage the uterine lining as to result in subsequent implantation failure. Unless specifically looked for, this will usually be unknown to the patient, who will simply present with secondary infertility. Treatment is often difficult because such patients might not respond adequately to surgical removal of intrauterine scar tissue or to hormonal or Viagra therapy
Male immunologic factors: Most men who have undergone a previous vasectomy more than 10 years earlier, will have antisperm antibodies that will interfere with fertilization. Such cases require IVF with intracytoplasmic sperm injection (ICSI). Here we offer a few words of caution to men who are considering undergoing surgical reversal of vasectomy. Always first have a test done to exclude the presence of circulating antisperm antibodies, because in such cases, even if the reversal is successfully performed, they will not be able to initiate a pregnancy without IVF/ICSI.
Whatever the cause, secondary infertility often affects older couples disproportionately, creating a sense of urgency and even desperation in achieving a viable pregnancy before time runs out. It is for this reason that IVF becomes the treatment of choice in such cases. However, even IVF becomes progressively less successful with advancing age of the woman (whose eggs are being fertilized). In such cases it is important for the couple to be realistic with regard to their expectations. Here, options that include embryo banking and egg donation should be carefully considered.
Another important point is that whenever a regularly ovulating younger woman (under 36 years of age) with patent fallopian tubes is diagnosed with secondary infertility, it is essential to consider underlying endometriosis or non-obstructive tubal disease as a possible cause. In such cases, IVF is again the treatment of choice.
b)
If you’ve undergone in vitro fertilization (IVF) and didn’t achieve a successful pregnancy, you may be wondering why. It’s important to know that IVF outcomes can be unpredictable, but there are factors that can affect your chances. Let’s explore some common reasons for IVF failure in simpler terms.
- Age: A woman’s age is a significant factor in IVF success. Generally, women under 35 have a higher chance of getting pregnant through IVF, around 35-40% per embryo transfer. However, this success rate decreases as women get older. For women in their mid-forties, the success rate drops to under 5%. This decline is mainly because the quality of eggs decreases as women age, affecting their ability to develop normally.
- Egg/Embryo Competency: Apart from age, the quality and competency of embryos also affect IVF success. The quality of eggs and embryos is influenced by a woman’s age. However, for older women or those with fewer eggs, the specific IVF protocol used to stimulate the ovaries becomes crucial. A more aggressive approach may be needed to maximize the chances of success. Previously, it was thought that the uterus was better for embryo development than the lab environment. So, early-stage embryos were transferred to the uterus based on their appearance. However, we now know that embryos that have progressed further in development are more likely to be successful. Embryos that don’t reach the blastocyst stage within 5-6 days after fertilization are considered less competent and not suitable for transfer. Additionally, Preimplantation Genetic Sampling / Testing (PGS/T) allows us to check the chromosomes of embryos. This technique helps select the most competent embryos for transfer, especially for older women, those with fewer eggs, repeated IVF failures, and recurrent pregnancy loss.
- Number of Embryos Transferred: Some people believe that transferring more embryos increases the chances of success. While this may have some truth, it’s essential to know that if the problem lies with the ovarian stimulation protocol, transferring more embryos won’t solve it. Also, transferring more embryos doesn’t fix issues related to embryo implantation dysfunction, such as anatomical or immunologic problems. Moreover, multiple embryos can lead to higher-order multiple pregnancies, which pose risks. To minimize these risks, it’s generally recommended to transfer a maximum of two embryos, or even just one, especially when using eggs from young women.
- Implantation Dysfunction (ID): Implantation dysfunction is often overlooked as a cause of unexplained IVF failure, especially in young women with normal ovarian reserve and fertile partners. Failure to identify and address these issues can result in repeated IVF failures. If transferring competent embryos repeatedly fails to result in a viable pregnancy, implantation dysfunction should be considered. The most common causes include:
-
- Thin Uterine Lining: When the lining of the uterus is too thin, it can affect the embryo’s ability to implant and grow.
- Surface Lesions in the Uterus: Polyps, fibroids, or scar tissue in the uterus can interfere with embryo implantation.
- Immunologic Implantation Dysfunction (IID): Sometimes, the immune system can mistakenly attack the embryo, preventing successful implantation.
- Endocrine/Molecular Endometrial Receptivity Issues: Hormonal or molecular issues in the uterine lining can impact the embryo’s ability to attach and develop.
- Ureaplasma Urealyticum (UU) Infection: This infection in the cervical mucous and uterine lining can lead to unexplained early pregnancy loss or IVF failure. Both partners should be tested and treated if positive to prevent transmission.
Certain causes of infertility are difficult or impossible to reverse, e.g.; advanced age of the woman, severe male infertility, and immunologic implantation dysfunction associated with certain specific genetic factors.
Understanding the common factors contributing to IVF failure can help you have informed discussions with your doctor and make decisions for future attempts. Factors like the number of embryos transferred and implantation dysfunction play significant roles. While success cannot be guaranteed, knowing these factors can guide you in maximizing your chances and addressing potential issues.
