I am 42 years old and had 1 failed IVF. I had 15 follicles, 11 retrieved, 6 became embryos but all 6 had chromosome abnormalities.. Is it worth doing IVF again
Yes, provided that an optimal protocol is used for ovarian stimulation.
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
My Bhcg on first blood test is 1377 and after two days it’s 3599. It’s my 4th week is it normal?
Please help
Normal!
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: Fatima S
Hello I am a 31 year old female I have two children ages 11 and 14, I don’t have any symptoms. My doc says I carry urea plasma parvum , we have tried to treat this year’s ago as they never used to test for it . And it’s only this one strain now that I’m ttc, and just experienced a chemical through IVF,I am worried it’s from this pathogen. I was told him I natural carrier of it.
I am no expert, but to my knowledge, the one to be concerned about is ureaplasma urealyticum.
Ureaplasma urealyticum is a bacterium that belongs to the mycoplasma family. It can be detected in the reproductive tract of as many as 40% of individuals (male and female). Ureaplasma probably does not prevent normal conception in the majority of cases, because by and large, the uterine cavity remains free of such pathogenic bacteria even in women whose cervical mucous cultures positive for the organism. However, when present in the woman’s cervical secretions, the organism can be unintentionally dragged into the uterine cavity through introduction of a catheter into the uterus at the time of embryo transfer (ET) or intrauterine insemination (IUI). Molecular biologists have shown that contamination of rapidly growing cell cultures, by this organism and its close “relative”, mycoplasma hominis rapidly destroys such cells. The implanting embryo is indeed an example of an organism that comprises rapidly growing cells in a biological culture medium (the uterine lining), and as such, the cells of the trophoblast that form the “root system” of the embryo are vulnerable to intrauterine infection with Ureaplasma. However, even if the uterine cavity were to become infected, the infection willl be purged with the shedding of the infected lining at the time of the next menstruation.
While , aside from a non-specific vaginal discharge, infection with Ureaplasma rarely produces symptoms in the woman, it sometimes causes symptomatic prostatitis or epydidimitis in men. Although ureaplasma can be transmitted from one partner to the other by sexual intercourse, it may also be acquired by other means, since a large percentage of couples in monogamous relationships will culture positive for the organism. It is very difficult for the organism to grow in the laboratory. Accordingly, the reproductive secretions of both partners should be evaluated (sperm and cervical mucus) individually. Successful culturing of ureaplasma requires a specialized media in which the specimens can be transported safely from the physician’s office to the microbiology laboratory.
If both partners culture negative, we can assume that there is no infection present. However, if one partner cultures positive and the other negative, we would err on the side of caution, by assuming that the negative result was caused by the difficulty in culturing the organism. When ureaplasma is detected in the reproductive secretions of either partner, both should be treated concurrently with the appropriate antibiotic (doxycycline, zithromax, erythromycin, ciprofloxin, or metronidazole; cleomycin).
Unfortunately, in approximately 30-40% of couples infected ureaplasma urealyticum, the bacteria will have built resistance to mainstay traditional antibiotics such as tetracyclines (e.g. doxycycline) and erythromycin (e.g. Zythromax) derivatives. In such cases, ciprofloxin or metronidazole (Flagyl) therapy might be needed. This is the reason that we prefer to document cure by reculturing each partner prior to beginning ovarian stimulation for an IVF cycle.
Several authors have shown a difference in pregnancy rates among patients with ureaplasma infection who were treated with antibiotics and those who were not. Other reports have not been able to identify an effect on outcome from ureaplasma infection. Thus, until the final verdict is in regarding the roll of ureaplasma with regard to its effect on IVF implantation, we prefer to err on the side of caution and ensure that this organism is absent in cervical secretions and semen before transferring embryos. To this end, my patients all receive prophylactic antibiotic therapy around the time of embryo transfer. This is administered as oral ciprofloxin. A day or two prior to embryo transfer, vaginal cleomycin suppositories are added.

Hello doctor,
I recently get to know that I am 4 weeks pregnant. My last periods date was 10th June 2023. On Saturday (8th july), I undergo for beta hcg test and I got 205.3 result. So, do I need to go for another hcg test before consulting any Gynaecologist?
Regards
In my opinion, if the levels have been increasing appropriately, there is no need. Do an US in 2-3 weeks for confirmation.

Hi,
I have done 4 rounds of egg freezing at 3 different clinics.
First round- 30 follicles growing, 15 retrieved but only 6 mature. I believe I was triggered to early as the majority of eggs were less than 16mm on day of trigger (only 6 were above). 375 gonal f and trigger of ovitrelle.
Second cycle. New clinic. Less follicles growing, 8 retrieved, 7 mature. The eighth one was matured in the lab for 2 hours and became mature so they froze that too. Dosage changed daily based on bloods but was around 150 Fostimon and 150 Meriofert. Trigger 10000 gonasi.
I then moved to a clinic abroad as I’m an expat so chose a clinic closer to me than my home country (U.K.)
Third cycle- about 14 follicles growing, 12 retrieved, 7 mature. They froze the 5 immature ones as well and will thaw these earlier when I come to use them to see if they can mature in the lab. 300 gonal f and 150 menopur. Dual trigger of 0.2 decapatyl and 7500 hcg.
Forth cycle- 21 follicles growing, 14 retrieved, 8 mature. They have again also frozen the 6 immature eggs. 300 folliculin and 150 humog. Trigger 0.2 decapatyl and around 8000 hcg.
My AMH never stays consistent. It has gone from 8.2 to 6.4, to 2.9 and then up to 9.6. No doctor can suggest why my AMH fluctuates. Instead they said to focus on the fact I get around 7 mature eggs each cycle.
My first 3 cycles were completed at the age of 34. And my last cycle at the age of 35 and 2 months.
My questions:
Why am I getting so many immature eggs? Does this suggest that my egg quality is poor? Should I also be concerned about the quality of my mature eggs? I’ve been told they look good quality.
How likely is it that the immature eggs will mature after thawing? Was there any point in the clinic freezing them?
Will 28/29 mature eggs be enough to give me the best chances of at least two children. Ideally I always wanted more children but I guess I need to rely on also getting pregnant naturally to give me the best chances. Should I consider another round?
Why does my AMH fluctuate?
In an ideal world I would have liked to have frozen a couple of years earlier but Covid meant this wasn’t possible. So it left me doing my cycles at the age of 34/35.
Any professional insight you have would be greatly appreciated.
Many thanks,
Emma
It seems as if you have produced enough “mature” eggs to give you a shot. However, as to the reason for so many immature egg cells, consider the following:
One of the commonest questions asked by patients undergoing IVF relates to the likelihood of their eggs fertilizing and the likely “quality of their eggs and embryos. This is also one of the most difficult questions to answer. On the one hand many factors that profoundly influence egg quality; such as the genetic recruitment of eggs for use in an upcoming cycle, the woman’s age and her ovarian reserve, are our outside of our control. On the other hand the protocol for controlled ovarian stimulation (COS) can also profoundly influence egg/embryo development and this is indeed chosen by the treating physician.
First, it should be understood that the most important determinant of fertilization potential, embryo development and blastocyst generation, is the numerical chromosomal integrity of the egg. While sperm quality does play a role, this is a relatively minor one unless there is severe sperm dysfunction. Human eggs have the highest rate of numerical chromosomal irregularities (aneuploidy) of all mammals. In fact, only about two thirds of the eggs of women in their twenties or early thirties, have the required number of chromosomes (euploid), without which upon fertilization they cannot propagate a normal pregnancy. As the woman advances into and beyond her mid-thirties, the percentage of eggs that are euploid declines progressively such that by the age of 40 years, only about one out of five or six eggs is likely to be chromosomally normal and by the time she reaches her mid-forties less than one in ten of her eggs will be euploid. This is due to the effect of “wear and tear” on eggs that are in the ovaries from before birth and which once they are gone, no treatment can replenish .
Second; embryos that fail to develop into blastocysts are almost always aneuploid and not worthy of being transferred to the uterus because they will either not implant, will miscarry or propagate a chromosomally abnormal baby (e.g. Down syndrome). However, it is incorrect to assume that all embryos reaching the blastocyst stage will be euploid (“competent”). Bear in mind that a high percentage of aneuploid embryos will succumb during early development and never attain blastocyst status while the few that do reach blastocyst might appear to morphologically normal while in fact they are aneuploid. It is a fact that embryos which fail to develop into blastocysts within 6 days of fertilization are almost invariably aneuploid and “incompetent “. It follows that blastocysts are far more likely to be competent than are earlier (cleaved embryos). What is also true is that the older the woman, the less likely it is that any given blastocyst will be “competent”. As an example, a morphologically pristine blastocyst derived from the egg of a 30-year-old woman would have about a 50:50 chance of being euploid and a 30% chance of propagating a healthy, normal baby, while a microscopically comparable blastocyst-derived through fertilization of the eggs from a 40+year-old, would be far less likely to be euploid and/or capable of propagating a healthy baby.
While the effect of species on the potential of eggs to be euploid at ovulation is genetically preordained and nothing we do can alter this equation, there is, unfortunately, a lot we can (often unwittingly) do to worsen the situation by selecting a suboptimal protocol of controlled ovarian stimulation (COS). This, by creating an adverse intraovarian hormonal environment will often disrupt normal egg development and lead to a higher incidence of egg aneuploidy than otherwise might have occurred. Older women, women with diminished ovarian reserve (DOR) and those with polycystic ovarian syndrome are especially vulnerable in this regard .It is believed that this is in large part is attributable to increased LH- induced over-production of ovarian testosterone which is common in older women, those who (regardless of their age) have DOR and in most women who have PCOS.
During the normal, ovulation cycle, small amounts of androgens (male hormones such as testosterone), are produced by the ovarian stroma (tissue surrounding ovarian follicles). Testosterone is vital for follicular growth and egg development. However, over-production of testosterone often has the reversed effect and can adversely affect follicle growth, egg development and IVF outcome. It is thus essential that ovarian stimulation protocols be tailored and individualized so as to avoid exposure to excessive ovarian androgen (testosterone) so as to optimize follicle growth and egg development. It is in my opinion, also important to avoid the administration of androgens (testosterone-containing drugs), the administration products that can provoke additional LH production by the pituitary gland (e.g., Lupron/Buserelin/Superfact/clomiphene/Letrozole) as well as overdosing with LH-containing fertility drugs (e.g., Menopur and Luveris), in older women, those with DOR and in cases of PCOS.
In summary, it is important to understand the influence species, age of the woman as well as the effect of the COS protocol can have on egg/embryo quality and thus on IVF outcome. The selection of an individualized protocol for ovarian stimulation is one of the most important decisions that the RE has to make and this becomes even more relevant when dealing with older women, those with diminished ovarian reserve (DOR) and women with PCOS. Such factors will in large part determine egg competency, fertilization potential, the rate of blastocyst generation and indeed IVF outcome.

Hi, can an estrogen priming ( 5 days before my period )or taking hGh 8 weeks prior to stimulation and during stimulation cause slower growth of follicles? My forth stimulation protocol is the same as the previos three ( third one was 3 months ago, the first and second two years), but my follicles are not growing. I’m taking Gonal f and Menopur (from day 4.). They increased the dose of Gonal f, but still going nowhere, it’ s day 11 of stimulation. Thank you for your answer. Polona
In my opinion, estrogen priming, by suppressing FSH, can suppress antral follicle formation and son delay follicle growth and development.

Hello!
I was told I have a 40mm cyst in my right ovary at my baseline Ivf ultrasound today. They called this afternoon and said my baseline bloodwork is normal (estrogen level is normal) and I can proceed with stim meds tomorrow. I am nervous the cyst will interfere with my follicle number/cohort and stim response (I am historically a poor responder). Any advice? Would you continue to stim or ask to delay?
Respectfully, I would not proceed with stimulation with a 40mm cyst present.
An ovarian cyst is any collection of fluid, surrounded by a very thin wall, within an ovary. An ovarian follicle that is larger than 22mm is termed a functional follicular cyst. They are non-malignant (benign) and harmless and in most cases, don’t even cause symptoms, however, in some cases, rapid distention of the cyst , or rupture with bleeding , can lead to sudden and severe pain and in some cases, a disruption in hormone balance leads to vaginal bleeding.
There are 2 varieties of “functional ovarian cysts:
- Follicle Cysts: In menstruating women, a follicle containing the unfertilized egg will rupture during ovulation. If this does not occur, a follicular cyst of more than 2.5 cm diameter may result. These cysts develop in response to stimulation with follicle stimulating hormone that is either self-produced (by the woman’s own pituitary gland (endogenous) or is induced by agonists (e.g. Lupron/Decapeptyl/Buserelin) that sometimes propagate increased and sustained pituitary FSH release.
- Corpus luteum cysts: These appear after ovulation or egg retrieval. The corpus luteum is the remnant of the follicle after the ovum has moved to the fallopian tubes. It usually degrades within 5-9 days. A corpus luteum of > 3 cm is regarded as being cystic.
A:Follicular cysts: These lesions have special relevance in women about to undergo controlled ovarian stimulation (COS) with gonadotropins for IVF where they can literally, “throw a spanner in the works”, causing a delay, postponement and sometimes even cancellation of the cycle of treatment.
Functional Ovarian cysts must be distinguished from “non-functional or cystic ovarian tumors”. By definition, “tumors are capable of independent growth. Thus “cystic ovarian tumors do not develop as a result of exposure to gonadotropin stimulation and it is this feature that distinguishes them from “functional” ovarian cysts.
Aside from sometimes causing pain and dysfunctional uterine bleeding, unruptured follicular cysts are usually relatively non-problematic. As stated above, in some cases, functional “cysts” undergo rapid distention (often as a result of a minor degree of bleeding inside the cyst itself). In such cases the woman will often experience a sharp or aching pain on one or other side of her lower abdomen and/or deep seated pain during intercourse. The cysts may even rupture, causing sudden lower abdominal pain that exacerbates and may even simulate an attack of acute appendicitis or a ruptured ectopic (tubular) pregnancy. While very unpleasant, a ruptured “functional cyst” seldom produces a degree of internal bleeding that warrants surgical intervention. The pain, typically is made worse by movement. It stabilizes within a number of days but subsides progressively to disappear within about four to seven days.
Whenever an ovarian cyst is detected (usually by ultrasound examination), the first consideration should be to determine whether it is a “functional cyst or a “cystic ovarian tumor”. The reason for this is that tumors are subject to a variety of complications such as twisting (torsion), hemorrhage, infection and even malignant change, all of which usually will require surgical intervention.
Gonadotropin releasing hormone agonists (GnRHa) such as Lupron, Buserelin, Nafarelin and Synarel, administered daily, starting a few days prior to menstruation, all elicit an initial and rapid, out-pouring (“surge”) in pituitary LH and FSH release. This “surge” lasts for a day or two. Then as the pituitary reservoir of FSH and LH becomes depleted, the blood FSH and LH levels fall rapidly reaching near undetectable blood levels within a day or two. At the same time, the declining FSH result in a drop in blood E2 concentration leading to a withdrawal bleed (menstruation). The progressive exhaustion of Pituitary FSH/LH along with the decline in blood E2, is referred to as ” down-regulation” The continued daily administration of GnRHa or its replacement (supplanting) with a GnRH antagonist (e.g. Ganirelix, Cetrotide or Orgalutron) results in blood LH concentrations being sustained at a very low level throughout the ensuing cycle of controlled ovarian hyperstimulation (COH) with gonadotropins, thereby optimizing follicular maturation and promoting E2 induced endometrial proliferation.
Functional follicular cysts resulting from controlled ovarian stimulation (COS), can occur regardless of whether down regulation with GnRHa (Lupron/Buserelin/Decapeptyl) is initiated in cases where the cycle of stimulation is launched with the woman coming off a BCP or when the agonist is initiated on day 20-23 (the mid luteal phase) of a natural cycle. When this happens it is due to the initial agonist-induced FSH “surge” sometimes so accelerating follicular growth that it leads to the development of one or more “functional follicular cysts”. These cysts release E2 and cause the blood E2 often to remain elevated (>70pg/ml). Depending on the extent of this effect, it sometimes leads to a delay in the onset of menstruation and thus also to deferment in the initiation of COS.
Failure of menstruation to commence within 4-7 days of initiating treatment with GnRHa suggestive of an underlying “functional ovarian cyst” and calls for an ultrasound examination to make the diagnosis. Once diagnosed, depending upon the number and size of cysts detected. There are two therapeutic options:
- Wait for the cyst to absorb spontaneously and for menstruation to ensue: While it at first might seem that this approach of continuing GnRHa therapy in order to cause absorption of the cyst(s) within a week or two might be a good approach , it often has unintended consequences. First there is the real possibility that prolonged uninterrupted GnRHa therapy might blunt subsequent ovarian follicular response to gonadotropin therapy and second, if menstruation does not follow within 10-14 days, the cycle will usually need to be cancelled.
- Immediate needle aspiration of the cyst(s) under local anesthesia. I personally favor needle aspiration, sooner rather than later in such cases. Menstruation will usually follow a successful aspiration within 2-4 days. Upon menstruation a blood E2 level is measured and as soon as it drops below 70pg/ml COS can be initiated.
- Corpus Luteum cysts: As with follicular cysts, so at times do Corpus Luteum cysts also bleed, distend and cause fain. They often delay onset of spontaneous menstruation by a week or longer (Halban syndrome”.). In isolated cases, internal bleeding within the cyst substance causes pain, rapid enlargement of the lesion and by ultrasound examination reveals local areas of absorption causing it to appear as a “complex” cystic lesion that simulates a tumor, prompting surgical intervention. Sadly, there are countless cases where women have had an entire ovary removed due to this happening.
“Functional ovarian cysts” rarely present as a serious health hazard. In the vast majority of cases they spontaneously resolve within 2-4 weeks while “cystic tumors” will not. Accordingly, the persistence of any ovarian cyst that persists for longer than 4 weeks should raise suspicion of it being a tumor rather than with a “functional cyst”. Since ovarian tumors can be (or become) malignant, all ovarian cysts that persist for longer than 6 weeks (whether occurring in non-pregnant or pregnant women), should be considered for surgical removal and this should be followed by pathological analysis.

My hcg level is 569 I just am not sure how far long I am
You are probably around 5 weeks pregnant. But this is a guestimate.
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: Rebecca M
I am currently undergoing IVF for PCOS, an ovulation. My first cycle I collected 26 eggs, 24 of which were mature and all fertilised and ended up with 12 day 5 blastocysts only 1 of low quality.
First FET resulted in chemical pregnancy and 2nd resulted in negative result. I have had all blood tests done and only thing that has been flagged is a spot I’ve ANA result at 1.80 titre with a speckled pattern. Also struggled to get my thyroid TSH to an optimal level ranged from 1.7 to 3.8. T4 and T3 always normal and no antibodies.
Should I be doing anything different for next transfer or any further investigations?
Implantation dysfunction is often overlooked as a significant reason for IVF failure. This is especially true when IVF failure is unexplained, or when there are recurring pregnancy losses or underlying issues with the uterus, such as endo-uterine surface lesions, thin uterine lining (endometrium), or immunological factors.
IVF success rates have been improving in the past decade. Currently, in the United States, the average live birth rate per embryo transfer for women under 40 years old using their own eggs is about 2:5 per woman undergoing embryo transfer. However, there is a wide range of success rates among different IVF programs, varying from 20% to almost 50%. Based on these statistics, most women in the United States need to undergo two or more IVF-embryo transfer attempts to have a baby. Many IVF practitioners in the United States attribute the differences in success rates to variations in expertise among embryology laboratories, but this is not entirely accurate. Other factors, such as differences in patient selection, the failure to develop personalized protocols for ovarian stimulation, and the neglect of infectious, anatomical, and immunological factors that affect embryo implantation, are equally important.
Approximately 80% of IVF failures occur due to “embryo incompetency,” mainly caused by ( irregularities in chromosome number (aneuploidy), which is often related to the advancing age of the woman, diminished ovarian reserve ( DOR) but can also be influenced by the ovarian stimulation protocol chosen, and sperm dysfunction (male infertility). However, in around 20% of cases with dysfunction, failure is caused by problems with embryo implantation.
This section will focus on embryo implantation dysfunction and IVF failure which in the vast majority of cases is caused by:
- 1. Anatomical irregularities of the inner uterine surface:
- a) Surface lesions such as polyps/fibroids/ scar tissue
- b)endometrial thickness
- 2. Immunologic Implantation Dysfunction ( IID)lesions
- a)Autoimmune IID
- b) Alloimmune IID
- ANATOMICAL IMPLANTATION DYSFUNCTION
- a) Surface lesions such as polyps/fibroids/ scar tissue
When there are problems with the structure of the uterus, it can lead to difficulties in getting pregnant. While uterine fibroids usually don’t cause infertility, they can affect fertility when they distort the uterine cavity or protrude through the lining. Even small fibroids located just beneath the lining and protruding into the cavity can decrease the chances of the embryo attaching. Multiple fibroids within the uterine wall that encroach upon the cavity can disrupt blood flow, impair estrogen delivery, and prevent proper thickening of the lining. These issues can be identified through ultrasound during the menstrual cycle’s proliferative phase. Any lesion on the uterine surface, such as submucous fibroids, adhesions, endometrial polyps, or placental polyps, can interfere with implantation by causing a local inflammatory response similar to the effect of an intrauterine contraceptive device (IUD).
Clearly, even small uterine lesions can have a negative impact on implantation. Considering the high costs and emotional toll associated with in vitro fertilization (IVF) and related procedures, it is reasonable to perform diagnostic tests like hysterosalpingography (HSG), fluid ultrasound examination (hysterosonogram), or hysteroscopy before starting IVF. Uterine lesions that can affect implantation often require surgical intervention. In most cases, procedures like dilatation and curettage (D&C) or hysteroscopic resection are sufficient. Rarely a laparotomy may be needed. Such interventions often lead to an improvement in the response of the uterine lining.
Hysterosonogram( HSN/saline ultrasound) is a procedure where a sterile saline solution is injected into the uterus through the cervix using a catheter. Vaginal ultrasound is then used to examine the fluid-filled cavity for any irregularities that might indicate surface lesions like polyps, fibroid tumors, scarring, or a septum. When performed by an expert, HSN is highly effective in detecting even the smallest lesions and can supplant hysteroscopy in certain cases. HSN is less expensive, less invasive/traumatic, and equally effective as hysteroscopy. The only drawback is that if a lesion is found, hysteroscopy may still be needed for treatment.
Hysteroscopy is a diagnostic procedure performed in an office setting with minimal discomfort to the patient. It involves inserting a thin, lighted instrument called a hysteroscope through the vagina and cervix into the uterus to examine the uterine cavity. Normal saline is used to distend the uterus during the procedure. Like HSN, hysteroscopy allows for direct visualization of the inside of the uterus to identify defects that could interfere with implantation. We have observed that around one in eight IVF candidates have lesions that need attention before undergoing IVF to optimize the chances of success. I strongly recommend that all patients undergo therapeutic surgery, usually hysteroscopy, to correct any identified issues before proceeding with IVF. Depending on the severity and nature of the problem, hysteroscopy may require general anesthesia and should be performed in a surgical facility equipped for laparotomy if necessary.
- b) Thickness of the uterine lining (endometrium)
As far back as In 1989, I and my team made an important discovery about using ultrasound to assess the thickness of the endometrium during the late proliferative phase of both “ natural” and hormone-stimulated cycles. The assessment helped predict the chances of conception. We found that an ideal thickness of over 9mm at the time of ovulation , egg retrieval or with the commencement of progesterone therapy in embryo recipient cycles ( e.g., IVF with egg donation, gestational, surrogacy and embryo adoption) was associated with optimal implantation rates, while an endometrial thickness of less than 8 mm was associated with failure to implant or early pregnancy loss in the vast majority of cases. An endometrium measuring <8mm was almost invariably associated with failure to implant or early pregnancy loss in the while an endometrium measuring 8 to 9 mm was regarded as being intermediate, and while pregnancies did occur in this range, the rates were only slightly lower than with an optimal lining of 9 mm
A “poor” uterine lining typically occurs when the innermost layer of the endometrium (basal or germinal endometrium) is unable to respond to estrogen by developing a thick enough outer “functional” layer to support successful embryo implantation and placental development. The “functional” layer, which accounts for two-thirds of the total endometrial thickness, is shed during menstruation if pregnancy does not occur.
The main causes of a poor uterine lining are:
- Damage to the basal endometrium due to:
-
- Inflammation of the endometrium (endometritis), often resulting from retained products of conception after abortion, miscarriage, or childbirth.
- Surgical trauma caused by aggressive dilatation and curettage (D&C).
- Insensitivity of the basal endometrium to estrogen due to:
-
- Prolonged (back to back) use of clomiphene citrate for ovarian stimulation or…
- Prenatal exposure to diethylstilbestrol (DES), a drug given to prevent miscarriage in the 1960s.
- Overexposure of the uterine lining to male hormones produced by the ovaries or administered during ovarian stimulation (primarily testosterone):
-
- Older women, women with DOR (poor responders), and women with polycystic ovarian syndrome (PCOS) often have increased biological activity of luteinizing hormone (LH), leading to testosterone overproduction by the ovarian connective tissue (stroma/theca). This effect can be further amplified when certain ovarian stimulation protocols were high doses of menotropins ( e.g., Menopur) are used.
- Reduced blood flow to the basal endometrium caused by:
-
- Multiple uterine fibroids, especially if they are located beneath the endometrium (submucosal).
- Uterine adenomyosis, which involves extensive abnormal invasion of endometrial glands into the uterine muscle.
In 1996 I introduced the Vaginal administration of Sildenafil (Viagra) to improve endometrial thickening. The selective administration of Sildenafil has shown great promise in improving uterine blood flow and increasing endometrial thickening in cases of thin endometrial linings. When administered vaginally, it is quickly absorbed and reaches high concentrations in the uterine blood system, diluting as it enters the systemic circulation. This method has been found to have minimal systemic side effects. However, it is important to note that Viagra may not be effective in all cases, as some cases of thin uterine linings may involve permanent damage to the basal endometrium, rendering it unresponsive to estrogen.
Severe endometrial damage leading to poor responsiveness to estrogen can occur in various situations. These include post-pregnancy endometritis (inflammation after childbirth), chronic granulomatous inflammation caused by uterine tuberculosis (rare in the United States), and significant surgical injury to the basal endometrium (which can happen after aggressive D&C procedures).
- IMMUNOLOGIC IMPLANTATION DYSFUNCTION (IID)
There is a growing recognition that problems with the immune function in the uterus can lead to embryo implantation dysfunction. The failure of proper immunologic interaction during implantation has been implicated as a cause of recurrent miscarriage, late pregnancy fetal loss, IVF failure, and infertility. Some immunologic factors that may contribute to these issues include antiphospholipid antibodies (APA), antithyroid antibodies (ATA) , and activated natural killer cells (NKa).
- Activated natural Killer Cells (NKa):
During ovulation and early pregnancy, the uterine lining is frequented by NK cells and T-cells, which together make up more than 80% of the immune cells in the uterine lining. These cells travel from the bone marrow to the endometrium where they proliferate under hormonal regulation. When exposed to progesterone, they produce TH-1 and TH-2 cytokines. TH-2 cytokines help the trophoblast (embryo’s “root system”) to penetrate the uterine lining, while TH-1 cytokines induce apoptosis (cell suicide), limiting placental development to the inner part of the uterus. The balance between TH1 and TH-2 cytokines is crucial for optimal placental development. NK cells and T-cells contribute to cytokine production. Excessive TH-1 cytokine production is harmful to the trophoblast and endometrial cells, leading to programmed cell death and ultimately to implantation failure. Functional NK cells reach their highest concentration in the endometrium around 6-7days after ovulation or exposure to progesterone, which coincides with the time of embryo implantation. It’s important to note that measuring the concentration of blood NK cells doesn’t reflect NK cell activation (NKa). The activation of NK cells is what matters. In certain conditions like endometriosis, the blood concentration of NK cells may be below normal, but NK cell activation is significantly increased.
There are several laboratory methods to assess NK cell activation (cytotoxicity), including immunohistochemical assessment of uterine NK cells and measuring TH-1 cytokines in the uterus or blood. However, the K-562 target cell blood test remains the gold standard. In this test, NK cells isolated from a woman’s blood are incubated with specific “target cells,” and the percentage of killed target cells is quantified. More than 12% killing indicates a level of NK cell activation that usually requires treatment. Currently, there are only a few Reproductive Immunology Reference Laboratories in the USA capable of reliably performing the K-562 target cell test.
There is a common misconception that adding IL (intralipid) or Intravenous gammaglobulin (IVIg) to NK cells can immediately downregulate NK cell activity. However, neither IL and IVIg cannot significantly suppress already activated NK cells. They are believed to work by regulating NK cell progenitors, which then produce downregulated NK cells. To assess the therapeutic effect, IL/IVIg infusion should be done about 14 days before embryos are transferred to the uterus to ensure a sufficient number of normal functional NK cells are present at the implantation site during embryo transfer. Failure to recognize this reality has led to the erroneous demand from IVF doctors for Reproductive Immunology Reference Laboratories to report on NK cell activity before and immediately after exposure to IVIg or IL at different concentrations. However, since already activated NK cells cannot be deactivated in the laboratory, assessing NKa suppression in this way has little clinical benefit. Even if blood is drawn 10-14 days after IL/IVIg treatment, it would take another 10-14 days to receive the results, which would be too late to be practically advantageous.
- Antiphospholipid Antibodies:
Many women who struggle with IVF failure or recurrent pregnancy loss, as well as those with a personal or family history of autoimmune diseases like lupus erythematosus, rheumatoid arthritis, scleroderma, and dermatomyositis, often test positive for antiphospholipid antibodies (APAs). Over 30 years ago, I proposed a treatment for women with positive APA tests. This involved using a low dose of heparin to improve the success of IVF implantation and increase birth rates. Research indicated that heparin could prevent APAs from affecting the embryo’s “root system” ( the trophoblast), thus enhancing implantation. We later discovered that this therapy only benefits women whose APAs target specific phospholipids (phosphatidylethanolamine and phosphatidylserine). Nowadays, longer-acting low molecular weight heparinoids like Lovenox and Clexane have replaced heparin.
- Antithyroid Antibodies ( thyroid peroxidase -TPO and antithyroglobulin antibodies (TGa)
Between 2% and 5% of women of the childbearing age have reduced thyroid hormone activity (hypothyroidism). Women with hypothyroidism often manifest with reproductive failure i.e., infertility, unexplained (often repeated) IVF failure, or recurrent pregnancy loss (RPL). The condition is 5-10 times more common in women than in men. In most cases hypothyroidism is caused by damage to the thyroid gland resulting from thyroid autoimmunity (Hashimoto’s disease) caused by damage done to the thyroid gland by antithyroglobulin and antimicrosomal auto-antibodies. The increased prevalence of hypothyroidism and thyroid autoimmunity (TAI) in women is likely the result of a combination of genetic factors, estrogen-related effects, and chromosome X abnormalities. This having been said, there is significantly increased incidence of thyroid antibodies in non-pregnant women with a history of infertility and recurrent pregnancy loss and thyroid antibodies can be present asymptomatically in women without them manifesting with overt clinical or endocrinologic evidence of thyroid disease. In addition, these antibodies may persist in women who have suffered from hyper- or hypothyroidism even after normalization of their thyroid function by appropriate pharmacological treatment. The manifestations of reproductive dysfunction thus seem to be linked more to the presence of thyroid autoimmunity (TAI) than to clinical existence of hypothyroidism and treatment of the latter does not routinely result in a subsequent improvement in reproductive performance. It follows that if antithyroid autoantibodies are associated with reproductive dysfunction they may serve as useful markers for predicting poor outcome in patients undergoing assisted reproductive technologies. Some years back, I reported on the fact that 47% of women who harbor thyroid autoantibodies, regardless of the absence or presence of clinical hypothyroidism, have activated uterine natural killer cells (NKa) cells and cytotoxic lymphocytes (CTL) and that such women often present with reproductive dysfunction. We demonstrated that appropriate immunotherapy with IVIG or intralipid (IL) and steroids subsequently often results in a significant improvement in reproductive performance in such cases.
Almost 50% of women with antithyroid antibodies do not have activated cytotoxic T lymphocytes (CTL) or natural killer cells (NK cells). This suggests that the antibodies themselves may not be the direct cause of reproductive dysfunction. Instead, the activation of CTL and NK cells, which occurs in about half of the cases with thyroid autoimmunity (TAI), is likely an accompanying phenomenon that damages the early “root system” (trophoblast) of the embryo during implantation.
Treating women who have both antithyroid antibodies and activated NK cells/CTL with intralipid (IL) and steroids improves their chances of successful reproduction. However, women with antithyroid antibodies who do not have activated NK cells/CTL do not require this treatment.
- Treatment Options for IID:
- Intralipid (IL) Therapy: IL is a mixture of soybean lipid droplets in water, primarily used for providing nutrition. When administered intravenously, IL supplies essential fatty acids that can activate certain receptors in NK cells, reducing their cytotoxic activity and enhancing implantation. IL, combined with corticosteroids, suppresses the overproduction of pro-inflammatory cytokines by NK cells, improving reproductive outcomes. IL is cost-effective and has fewer side effects compared to other treatments like IVIg.
- Intravenous immunoglobulin-G (IVIg) Therapy:In the past, IVIg was used to down-regulate activated NK cells. However, concerns about viral infections and the high cost led to a decline in its use. IVIg can be effective, but IL has become a more favorable and affordable alternative.
- Corticosteroid Therapy: Corticosteroids, such as prednisone and dexamethasone, are commonly used in IVF treatment. They have an immunomodulatory effect and reduce TH-1 cytokine production by CTL. When combined with IL or IVIg, corticosteroids enhance the implantation process. Treatment typically starts 10-14 days before embryo transfer and continues until the 10th week of pregnancy.
- Heparinoid Therapy: Low molecular weight heparin (Clexane, Lovenox)can improve IVF success rates in women with antiphospholipid antibodies (APAs) and may prevent pregnancy loss in certain thrombophilias when used during treatment. It is administered subcutaneously once daily from the start of ovarian stimulation.
- TH-1 Cytokine Blockers (Enbrel, Humira):TH-1 cytokine blockers have limited effectiveness in the IVF setting and, in my opinion, no compelling evidence supports their use. They may have a role in treating threatened miscarriage caused by CTL/NK cell activation, but not for IVF treatment. TH-1 cytokines are needed for cellular response, during the early phase of implantation, so completely blocking them could hinder normal implantation.
- Baby Aspirin and IVF:Baby aspirin doesn’t offer much value in treating implantation dysfunction (IID) and may even reduce the chance of success. This is because aspirin thins the blood and increases the risk of bleeding, which can complicate procedures like egg retrieval or embryo transfer during IVF, potentially compromising its success.
- Leukocyte Immunization Therapy (LIT):LIT involves injecting the male partner’s lymphocytes into the mother to improve the recognition of the embryo as “self” and prevent rejection. LIT can up-regulate Treg cells and down-regulate NK cell activation, improving the balance of TH-1 and TH-2 cells in the uterus. However, the same benefits can be achieved through IL (Intralipid) therapy combined with corticosteroids. IL is more cost-effective, and the use of LIT is prohibited by law in the USA.
Types of Immunologic Implantation Dysfunction (IID) and NK Cell Activation:
- 1.Autoimmune Implantation Dysfunction: Women with a personal or family history of autoimmune conditions like Rheumatoid arthritis, Lupus Erythematosus, thyroid autoimmune disease (Hashimoto’s disease and thyrotoxicosis), and endometriosis (in about one-third of cases) may experience autoimmune IID. However, autoimmune IID can also occur without any personal or family history of autoimmune diseases. Treatment for NK cell activation in IVF cases complicated by autoimmune IID involves a combination of daily oral dexamethasone from the start of ovarian stimulation until the 10th week of pregnancy, along with 20% intralipid (IL) infusion 10 days to 2 weeks before embryo transfer. With this treatment, the chance of a viable pregnancy occurring within two completed embryo transfer attempts is approximately 70% for women <40 years old who have normal ovarian reserve.
- Alloimmune Implantation Dysfunction:NK cell activation occurs when the uterus is exposed to an embryo that shares certain genotypic (HLA/DQ alpha) similarities with the embryo recipient.
-
-
- Partial DQ alpha/HLA genetic matching: Couples who share only one DQ alpha/HLA gene are considered to have a “partial match.” If NK cell activation is also present, this partial match puts the couple at a disadvantage for IVF success. However, it’s important to note that DQ alpha/HLA matching, whether partial or total, does not cause IID without associated NK cell activation. Treatment for partial DQ alpha/HLA match with NK cell activation involves IL infusion and oral prednisone as adjunct therapy. IL infusion is repeated every 2-4 weeks after pregnancy is confirmed and continued until the 24th week of gestation. In these cases, only one embryo is transferred at a time to minimize the risk of NK cell activation.
- Total (Complete) Alloimmune Genetic Matching: A total alloimmune match occurs when the husband’s DQ alpha genotype matches both that of the partner. Although rare, this total match along with NK cell activation significantly reduces the chance of a viable pregnancy resulting in a live birth at term. In some cases, the use of a gestational surrogate may be necessary.
-
It should be emphasized that poor embryo quality is not always the main cause of reproductive dysfunction and that the complex interaction between embryonic cells and the lining of the uterus plays a critical role in successful implantation. Women with personal or family histories of autoimmune disease or endometriosis and those with unexplained (often repeated) IVF failure or recurrent pregnancy loss, often have immunologic implantation dysfunction (IID as the underlying cause . For such women, it is important to understand how IID leads to reproductive failure and how selective treatment options such as intralipid (IL), corticosteroid and heparinoid therapy, can dramatically improve reproductive outcomes. Finally, there is real hope that proper identification and management of IID can significantly improve the chance of successful reproduction and ultimately contribute to better quality of life after birth.

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!
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!
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 🙂
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.
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
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

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
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.

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.
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.
