Synarel and DHEA

Name: Linda B

Hi, I have been a responding best to the long protocol where I start with Synarel on day 21. Because of low testosterone I’ve been taking DHEA for the last weeks. I read that DHEA can cause an increase in estrogen, while Synarel is suppose to decrease estrogen. Is it therefore a bad idea to continue with DHEA during down regulation? Should I stop as soon as I start down regulation or is it okay to continue DHEA during down regulation and stims? Thank you in advance for your input!

Answer:

Synarel is a GnRH agonist. It is administered nasally. As such, absorption sometimes erratic. I prefer Lupron or decapeptyl which are administered intramuscularly.

Dehydroepiandrosterone (DHEA), is steroid hormone produced by the adrenal glands and ovary. It is involved in producing the male hormones, androstenedione testosterone and also estrogen. DHEA blood levels tend to decline naturally with age.

 

Under the effect if luteinizing hormone (LH), DHEA is metabolized to testosterone in ovarian connective tissue (theca/stroma). Thereupon the testosterone is transported to the granulosa cells that form the innermost layer of the ovarian follicles where, under the influence of follicle stimulating hormone (FSH)-induced desmolase and aromatase enzymatic activity the testosterone is converted to estradiol. As this happens, granulosa cells multiply, follicle fluid volume increases along with estrogen output and egg development is promoted.

 

It is recognition of the essential/indispensable role that male hormones (mainly testosterone) play in follicle and egg development that prompted the belief that by giving DHEA and boosting ovarian testosterone production might benefit follicle/egg development. This belief was given some credence by an Israeli study that in 2010 reported on improved fertility when a group of infertile women were given the administration of 75mg of oral DHEA for 5 months. However, this study was seriously flawed by the fact that it did not separate out women who had diminished ovarian reserve, older women and those with PCOS, all of whom have increased LH-induced production of testosterone. In fact, we recently completed a study (currently being processed for publication) where we conclusively showed that when follicular fluid testosterone levels exceeded a certain threshold, egg quality was seriously prejudiced as evidenced by a marked increase in the incidence of egg chromosomal defects (aneuploidy).

 

Consider the following: Ovarian testosterone is needed for follicular development. However, the amount required is small. Too much ovarian testosterone spills over into the follicular fluid and has a deleterious effect on egg/follicle development. Some women (women with diminished ovarian reserve –DOR, older women and those with polycystic ovarian syndrome-PCOS) who tend to have increased LH biological activity, already over-produce testosterone. To such women, the administration of DHEA to such women, by “adding fuel to the fire” can be decidedly prejudicial, in my opinion. Young women with normal ovarian reserve do not over produce LH-induced ovarian testosterone, and are thus probably not at significant risk from DHEA supplementation. It is noteworthy that to date, none of the studies that suggest a benefit from DHEA therapy have differentiated between young healthy normal women with normal ovarian reserve on the one hand and older women, those with DOR and women with PCOS on the other hand.

 

In Some countries DHEA treatment requires a medical prescription and medical supervision. Not so in the U.S.A where it can be bought over the counter.  Since DHEA is involved in sex hormone production, including testosterone and estrogen, individuals with malignant conditions that may be hormone dependent (certain types of breast cancer or testicular cancer) should not receive DHEA supplementation. Also, if overdosed with DHEA some “sensitive women” might so increase their blood concentrations of testosterone that they develop increased aggressive tendencies or male characteristics such as hirsuites (increased hair growth) and a deepening voice. DHEA can also interact other medications, such as barbiturates, corticosteroids, insulin and with other oral diabetic medications.

 

BUT the strongest argument against the use of routine DHEA supplementation is the potential risk of compromising egg quality in certain categories of women and since there is presently no convincing evidence of any benefit, why take the risk in using it on anyone.

 

Finally, for those who in spite of the above, still feel compelled to take DHEA, the best advice I can give is to consult their health care providers before starting the process.

 

Addendum: One potential advantage of DHEA therapy if used appropriately came from a study conducted by Washington University School of Medicine in St. Louis, MI and reported in the November 2004 issue of the “Journal of the American Medical Association” which showed that judicious (selective) administration of 50mg DHEA daily for 6 months resulted in a significant reduction of  abdominal fat and blood insulin in elderly women.

Human Growth Hormone Administration in IVF

Name: Alejandra G

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 🙂

Author

Answer:

No! You (in my opinion) do not need to take the HGH for long. My patients start a week before ovarian stimulation commences.

Hcg

Name: Timi G

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.

Author

Answer:

I don’t think attending a concert will prejudice your pregnancy!

Going through IVF is a major investment, emotionally, physically, and financially, for every patient or couple. One of the most crucial moments is receiving the result of the blood test for human chorionic gonadotropin (hCG) pregnancy. It’s a big deal! The days after the embryo transfer, waiting for this result, can be extremely stressful. That’s why it’s crucial for the IVF doctor and staff to handle this information with care and professionalism. They should be accessible to the patient/couple and provide results promptly and sensitively.

Testing urine or blood to check for human chorionic gonadotropin (hCG) is the best way to confirm pregnancy. Urine tests are cheaper and more commonly used. They are also more convenient because they can be done anywhere. However, blood tests are more reliable and sensitive than urine tests. They can detect pregnancy earlier and at lower hCG levels. Blood tests are also more accurate and can track changes in hCG levels over time. Urine tests can detect hCG when blood levels are above 20IU, which is about 16-18 days after ovulation or 2-3 days after a missed period. Blood tests can measure any concentration of hCG about 12-13 days after ovulation.

Detecting hCG in the blood early on and tracking its increase is especially useful for women undergoing fertility treatments like controlled ovarian stimulation or in vitro fertilization. The sooner hCG is detected and measured, the more information can be gathered about the success of implantation and the health of the developing embryo.

Typically, two beta hCG blood tests are done, spaced 2-4 days apart. It’s best to wait for the results of the second test before reporting on the pregnancy. This is because an initial result can change, even from equivocal or negative to positive. Sometimes a normal embryo takes longer to implant, and the hCG level can be initially low or undetectable. Regardless of the initial level, the test should be repeated after two days to check for a significant rise in hCG. A significant rise usually indicates that an embryo is implanting, which suggests a possible pregnancy. Waiting for the second test result helps avoid conveying false hope or disappointment.

It’s important to note that beta hCG levels don’t double every two days throughout pregnancy. Once the levels rise above 4,000U, they tend to increase more slowly. Except in specific cases like IVF using an egg donor or transfer of genetically tested embryos, the birth rate following IVF in younger women is around 40% per embryo transfer. Patients need to have realistic expectations and should be informed about how and when they will receive the news, as well as counseling in case of a negative outcome.

When an embryo starts to implant, it releases the pregnancy hormone hCG into the woman’s bloodstream. Around 12 days after egg retrieval, 9 days after a day 3 embryo transfer, or 7 days after a blastocyst transfer, a woman should have a quantitative beta hCG blood pregnancy test performed. By that time, most of the hCG injected to prepare the eggs for retrieval should have cleared from the bloodstream. So, if the test detects more than 10 IU of hCG per ml of blood, it indicates that the embryo has attempted to implant. In third-party IVF (e.g., ovum donation, gestational surrogacy, embryo adoption, or frozen embryo transfers), no hCG trigger is administered, so any amount of hCG detected in the blood is considered significant.

Sometimes, there is a slow initial rise in hCG between the first and second tests (failure to double every 48 hours). In such cases, a third and sometimes a fourth hCG test should be done at two-day intervals. A failure to double on the third and/or fourth test is a poor sign and could indicate a failed or dysfunctional implantation. In some cases, a progressively slow rising hCG level might indicate an ectopic pregnancy, which requires additional testing and follow-up.

In certain situations, the first beta hCG level starts high, drops with the second test, and then starts doubling again. This could suggest that initially, multiple embryos started to implant but only one survived to continue a healthy implantation.

It’s customary for the IVF clinic staff to inform the patient/couple and the referring physician about the hCG pregnancy test results. Often, the IVF physician or nurse-coordinator coordinates with the referring physician to arrange all necessary pregnancy tests. If the patient/couple prefer to make their own arrangements, the program should provide detailed instructions.

In some cases, when the two blood pregnancy tests show that one or more embryos are implanting, certain programs recommend daily injections of progesterone or the use of vaginal hormone suppositories for several weeks to support the implantation process. Others give hCG injections three times a week until the pregnancy can be confirmed by ultrasound examination. Some IVF programs don’t prescribe any hormones after the embryo transfer.

Patients with appropriate doubling of hCG levels within two days after frozen embryo transfer (FET) or third-party IVF procedures such as surrogacy or egg donation may receive estradiol and progesterone injections, often along with vaginal hormone suppositories, for 10 weeks after the implantation is diagnosed by blood pregnancy testing.

A positive Beta hCG blood pregnancy test indicates the possibility of conception, but ultrasound confirmation is needed to confirm the pregnancy. Until then, it is referred to as a “chemical pregnancy.” Only when ultrasound examination confirms the presence of a gestational sac, clinical examination establishes a viable pregnancy, or after abortion when products of conception are detected, is it called a clinical intrauterine pregnancy.

A significantly elevated  hCG blood level without concomitant detection of an gestational sac inside the uterus by ultrasound after 5 weeks gestation raises the suspicion of an ectopic (tubal) pregnancy.

The risk of miscarriage gradually decreases once a viable clinical pregnancy is diagnosed (a conceptus with a regular heartbeat of 110-180 beats per minute). From this point onward, the risk of miscarriage is usually 10- 15% for women under 40 years old and around 35% for women in their early forties.

Dealing with successful IVF cases is relatively easy as everyone feels happy and validated. The real challenge lies in handling unsuccessful cases. Setting rational expectations from the beginning is crucial. In some cases (fortunately rare), emotional pressure may overwhelm the patient/couple, leading to a need for counseling or psychiatric therapy. I always advise my patients that receiving optimal care doesn’t always guarantee the desired outcome. There are many variables beyond our control, especially the unpredictable nature of fate. With around 36 years of experience in this field, I strongly believe that when it comes to IVF, the saying “man proposes while God disposes” always holds.

There are a few important things to consider when interpreting blood hCG levels. Levels can vary widely, ranging from 5mIU/ml to over 400mIU/ml, 10 days after ovulation or egg retrieval. The levels double every 48-72 hours until the 6th week of pregnancy, after which the doubling rate slows down to about 96 hours. By the end of the 1st trimester, hCG levels reach 13,000-290,000 IU and then slowly decline to around 26,000-300,000 IU at full term. Here are the average hCG levels during the first trimester:

  • 3 weeks after the last menstrual period (LMP): 5-50 IU
  • 4 weeks LMP: 5-426 IU
  • 5 weeks LMP: 18-7,340 IU
  • 6 weeks LMP: 1,080-56,500 IU
  • 7-8 weeks LMP: 7,650-229,000 IU
  • 9-12 weeks LMP: 25,700-288,000 IU

Most doctors wait until around the 7th week to perform an ultrasound to confirm pregnancy. By that time, the heartbeat should be clearly visible, providing a more reliable assessment of the pregnancy’s viability.

In some cases, blood hCG levels can be unusually high or increase faster than normal. This could indicate multiple pregnancies or a molar pregnancy. Rarely, conditions unrelated to pregnancy, such as certain ovarian tumors or cancers, can cause detectable hCG levels in both blood and urine.

 

To summarize, testing urine or blood for hCG is the most reliable way to confirm pregnancy. Urine tests are more common and convenient, while blood tests are more accurate and can detect pregnancy earlier. Tracking hCG levels in the blood is especially important for women undergoing fertility treatments. It’s essential to wait for the results of a second blood test before confirming pregnancy to avoid false hope or disappointment. Interpreting hCG levels requires considering various factors, and doctors usually perform an ultrasound around the 7th week for a more accurate assessment. Unusually high hCG levels may indicate multiple pregnancies or other conditions unrelated to pregnancy. Providing sensitive and timely communication of results is crucial for IVF clinics to support patients through the emotional journey.

Empty follicles

Name: Feriba E

Hi dear doctorI hope you are well ,why my All my three follicles was empty I used controlled ovarian stimulation thanks a lot

Author

Answer:

Frequently, when following vigorous and often repeated flushing of follicles at egg retrieval they fail to yield eggs, it is ascribed to “Empty Follicle Syndrome.” This is a gross misnomer, because all follicles contain eggs. So why were no eggs retrieved from the follicles? Most likely it was because they would/could not yield the eggs they harbored.

This situation is most commonly seen in older women, women who have severely diminished ovarian reserve, and in women with polycystic ovarian syndrome (PCOS). In my opinion it is often preventable when an optimal, individualized and strategic protocol for controlled ovarian stimulation (COS) is employed and the correct timing and dosage is applied to the “hCG trigger shot.

Normally, following optimal ovarian stimulation, the hCG “trigger shot” is given for the purpose of it triggering meiosis (reproductive division) that is intended to halve the number of chromosomes from 46 to 23 within 32-36 hours. The hCG trigger also enables the egg to signal the “cumulus cells” that bind it firmly to the inner wall of the follicle (through enzymatic activity), to loosen or disperse, so that the egg can detach and readily be captured at egg retrieval (ER).

Ordinarily, normal eggs (and even those with only one or two chromosomal irregularities) will readily detach and be captured with the very first attempt to empty a follicle. Eggs that have several chromosomal numerical abnormalities (i.e., are “complex aneuploid”) are often unable to facilitate this process. This explains why when the egg is complex aneuploid, its follicle will not yield an egg…and why, when it requires repeated flushing of a follicle to harvest an egg, it is highly suggestive of it being aneuploid and thus “incompetent” (i.e., incapable of subsequently propagating a normal embryo).

Older women, women with diminished ovarian reserve, and those with polycystic ovarian syndrome, tend to have more biologically active LH in circulation. LH causes production of male hormone (androgens, predominantly testosterone), by ovarian connective tissue (stroma/theca). A little testosterone is needed for optimal follicle development and for FSH-induced ovogenesis (egg development). Too much LH activity compromises the latter, and eggs so affected are far more likely to be aneuploid following meiosis.

Women with the above conditions have increased LH activity and are thus more likely to produce excessive ovarian testosterone. It follows that sustained, premature elevations in LH or premature luteinization (often referred to as a “premature LH surge”) will prejudice egg development. Such compromised eggs are much more likely to end up being complex aneuploid following the administration of the hCG trigger, leading to fruitless attempts at retrieval and the so called “empty follicle syndrome.”

The developing eggs of women who have increased LH activity (older women, women with diminished ovarian reserve, and those with PCOS) are inordinately vulnerable to the effects of protracted exposure to LH-induced ovarian testosterone. Because of this, the administration of medications that provoke further pituitary LH release (e.g., clomiphene and Letrozole), drugs that contain LH or hCG (e.g., Menopur), or protocols of ovarian stimulation that provoke increased exposure to the woman’s own pituitary LH (e.g., “flare-agonist protocols”) and the use of “late pituitary blockade” (antagonist) protocols can be prejudicial.

The importance of individualizing COS protocol selection, precision with regard to the dosage and type of hCG trigger used, and the timing of its administration in such cases cannot be overstated. The ideal dosage of urinary-derived hCG (hCG-u) such as Novarel, Pregnyl and Profasi is 10,000U. When recombinant DNA-derived hCG (hCG-r) such as Ovidrel is used, the optimal dosage is 500mcg. A lower dosage of hCG can, by compromising meiosis, increase the risk of egg aneuploidy, and thus of IVF outcome.

There is in my opinion no such condition as “Empty Follicle Syndrome.” All follicles contain eggs. Failure to access those eggs at ER can often be a result of the protocol used for controlled ovarian stimulation.

PGT-A

Name: Vess V

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.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.

  1. 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.
  2. 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.
  3. 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:
  1. 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.
  1. 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
  1. 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.

When Should I Stop Lovenox?

Name: Lena M

Hi Dr. Sher,

I am 41 years old and I am currently 8 weeks and 5 days pregnant through IVF and I need a second opinion when to stop Lovenox. Just to provide some background, I had two failed embryo transfers with AA euploid blastocysts. Then I was diagnosed with endometriosis and had excision surgery in March 2023. Also, I have these gene mutations:
PAI-1 (675 5G>4G) Homozygous
MTR (2756 A>G) Heterozygous
MTHFR (1298 A>C) Heterozygous
MTRR (66 A>G) Homozygous

I had test for homocysteine on 06/2023 – 5.8 umol/L
Test for PLASMINOGEN ACTIVATOR INHIBITOR 1 in 2021 – 5ng/ml
I am taking methylfolate form of folic acid.

Currently as part of IVF protocol besides progesterone/estrogen I am taking these medications since I had slightly elevated Th1/Th2 ratio and to reduce inflammation:
Prednisone 20mg/day
Tacrolimus 1mg/day
Lovenox 40
Aspirin 81

The doctor recommends stopping lovenox and tacrolimus at the end of week 9 and starting weaning down prednisone. I noticed that most people stop lovenox at the end of week 12 and want to ask what you would be recommendation. Also want to ask if there any pregnancy risks associated with gene mutations I have and do I need to do any specific bloodwork related to them?

Thank you,
Lena

Answer:

I would continue all the way through pregnancy and the 1st 6 weeks thereafter.

Thrombophilia (Hereditary Clotting Defect) is defined as the genetic predisposition to developing intravascular thrombosis. It is due to hypercoagulability of blood leading to impairment of initial vascularization that takes place during implantation.

Thrombophilia affects as many as one in five people in the United States and is responsible for pregnancy loss (most particularly after the 1st trimester) and “unexplained” infertility, as well as being a factor in some cases of “unexplained” IVF failure. Whether (and/or the extent to which) thrombophilia causes 1st trimester recurrent pregnancy loss (RPL) is the subject of debate and is controversial. In fact, first-trimester RPL is far more likely to be due to immunologic implantation dysfunction (IID) and/or irregularities in the contour of the uterine cavity or insufficient thickness of its lining (a thin endometrium). Thrombophilia has also been associated with late pregnancy-induced complications such as preeclampsia, premature separation of the placenta (abruptio placenta), placental insufficiency with intrauterine growth retardation, and in “unexplained” intrauterine death.

This having been said, it is a fact that most women with a thrombophilia go on to experience healthy pregnancies.

Diagnosis of Throbophilia

Thrombophilia is diagnosed when one or more of the following is detected:

  • Mutational defect involving methylenetetrahydrofolate reductase (MTHFR), which occurs in at least 20% of affected cases. Homozygosity for a common C677T mutation in the MTHFR gene that is associated with hyperhomocysteinemia is the most common form of hereditary thrombophilia leading to a 3-fold increase in risk of complications.
  • Mutation of factor V Leiden (FVL),
  • A mutation of prothrombin G20210A,
  • Deficiency of antithrombin III
  • Deficiency of protein C
  • Deficiency of protein S

Risk Factors

  • Pregnant women with predisposing factors such as:
  • A personal or family history of thromboembolism (deep vein thrombosis), pulmonary embolism (blood clot in the lung), cerebrovascular accidents (i.e. strokes)
  • A personal history of pregnancy complications such as unexplained intrauterine death, preeclampsia, abruptio placenta, intrauterine growth retardation, placental insufficiency, should be tested for the condition.

Treatment

Treatment should be initiated as soon as possible after pregnancy is diagnosed biochemically (blood or urine hCG test) and be continued throughout gestation.

Severe thrombophilias (e.g. homozygous MTHFR mutations, protein C deficiency, prothrombin G20210A mutation) as well as cases of mild thrombophilias associated  with one or more of the pregnancy complications mentioned above, are best treated with low-molecular weight heparin (LMWH) taken throughout pregnancy.

For other (milder) thrombophilias and no history of prior pregnancy complications: Low-dose aspirin with the B vitamins folic acid, B6 and B12.
