  1. Dear Doctor,
    I have a rare situation where I actually ovulate with extremely low estrogen. My estrogen never goes above 50 but I ovulate and get a period. The doctors tell me it is impossible to ovulate with such low estrogen but when I get my period 14 days after my surge, they cannot understand. How does this happen?

    • Perhaps the measurement is incorrect or you are measuring a day or more before the LH surge? It is also possible that you are measuring E2 after ovulation has occurred and if so the E2 will be lower by as much as 80%, because it usually drops immediately after ovulation.

  2. Dear Dr Geoffrey
    I have found your blog after doing some research about selective reduction after Ivf. I’m based in the uk & there is very little information available. I’m waiting for another scan but it appears I have 3 foetuses- I’m currently at 7 weeks. I want to reduce this to a singleton but this doesn’t seem to be done in the uk. Is it something you offer- and if yes how would I go about doing this and what would the costs be? As you can imagine this is an emotional subject to be discussing so I would appreciate being able to hear the facts. I read somewhere that there was only a 5% chance of miscarriage to the remaining foetus- is this true? Thanking you in advance.

    • Please can you remove my photograph from my message?

    • We do not do reductions. However, feel free to call my office at 702-892-9696 and ask for Briana Ohel RN. She will provide you with information on how to reach a Dr in Las Vegas to whom were refer such cases which fortunately is not common.

      Good luck!

  3. Good afternoon, Dr. Sher. Sorry for my anliysky. I’m from Russia.
    My mutation hemostasis: MTRR (66A>G) – A/G; FX||| (163 G>T) – G/T; ITGA2 (807 C>T) – C/T; PAI-1 (-675 5G /4G) – 5G/4G.
    My husband and I have 3 matches on the HLA system. The husband: DRB1 (03; 13), DQA1 (0102; 0501), DQB1 (02; 0602-8). I: DRB1 (01; 13), DQA1 (0101; 0102), DQB1 (0501, 0602-8). We are together 10 years, no children. In 2013 was artificial insemination, pregnancy stopped for 5-6 week. In 2016 there was another attempt at insemination and IVF without success. Becoming a donor lymphocytes, every 3 weeks, did not help. We both checked and healthy. Hormones are normal. The doctor says that the only problem is the HLA. But nothing to offer other than lymphocytes. I want to try Intralipid. Please tell us in detail how to use it. How to dilute, how much, how often. And do I need something else to take? In any case take Prednisolone? Thanks in advance.

    • Hi Olosya,

      Indeed you do have a partial DQ alpha match if the results you present are reliable. Now what needs to be knpown is whether you also have NK cell activation (NKa) by the K-562 target cell test. I suspect that you do have such because it could explain your situation fully. If however you do not have NKa then the match would bve irrelevant and it would not be advantageous to treat with Intralipid/prednisone therapy.

      I suggest that you have your blood sent to one of the 5 reproductive immunology reference laboratories in the USA. I have many European and Russian patients and have not been able to identify any reliable alternative in Eurasia. I use Reproductive Imm8unology aAssociates in Van Nuys, CA. Their contact # is 805-578-7002. Call them and mention my name. Ask them how you can overnight your and your partner’s blood to them for the following tests: NKa (k-562-target cell test), APA, ATA, RIP, ANA…on your blood and DQ alpha/HLA, on both your and yoyur partbner’s blood. Have them also send me a copy and we can review this together, later.

    • Thank you! Yes, the results are correct. Did I understand you correctly? The problem with the conception and intra only when the partners are identical for DQA1. If we have a partial DQA1, the DQB1 and DRB1 are not important and the reason is different, such as NK cells or something else.
      I’ll do the tests that you have written and will write you the result.

    • Good afternoon, the doctor! I heard that prohibited limfotsitoterapiya (immunization with lymphocytes husband) according to the law in the United States. Is it so? And what is it dangerous? Here in Russia it is very widely used. Lymphocytes give every 3 weeks until the result. I placed 10 times in a row every 3 weeks. After that, I increased lymph nodes. For whatever scheme put Intralipid? We have no one knows about it.

  4. Hi Dr,
    Apparently have unexplained Infertility. I am 41 years old ( 57kgs ), and my husband is 37 years old ( 85kgs ). I have 2 children to a previous marriage, ages 14 and 16. My husbands Sperm tests are normal, and apparently ALL of my tests are normal. We have been TTC for 5 years. I have been a very poor responder to every cycle, only ever producing 2 follicles at the most.
    We are about to start our 5th IVF cycle.
    Cycle 1 – IVF with ICSI – Pill Down Regulation – Synarel spray twice daily – Peregon 225i.u injection once daily – 2 follicles at scan – 2 eggs collected – 1 egg fertilised – 1 x ( 2 day old ) embryo transferred – Luteal Phase Endometrin 100.00mgs – BFN
    Cycle 2 – IVF with ICSI – FSH Antagonist – Menopur Injection 450i.u once daily – Orgalutran Injection 250mcg once daily – 2 follicles at scan – 2 eggs collected – 1 egg fertilised – 1 x ( 2 day old ) embryo transferred – Luteal Phase Crinone 90.00mgs – BFN
    Cycle 3 – IVF – FSH Antagonist – Gonal F injection 300i.u once daily – Orgalutran injection 250mcg once daily – 2 follicles at scan – 2 eggs collected – 1 egg fertilised – 1 x ( 2 day old ) embryo transferred – Luteal Phase Crinone 90.00mgs – BFN
    Cycle 4 – IVF with ICSI – FSH Antagonist – Gonal F injection 300i.u once daily – Orgalutran Injection 250mcg once daily – Menopur 112.5i.u once daily – 1 follicle at scan – 0 eggs collected
    Cycle 5 starting within the next 2 weeks.
    Do you have any advise for me on different treatment cycles I could try in the hope of getting more follicles, therefore hopefully more eggs?

    • The older a woman becomes, the more likely it is that her eggs will be chromosomally/genetically “incompetent” (not have the potential upon being fertilized and transferred, to result in a viable pregnancy). That is why, the likelihood of failure to conceive, miscarrying and of giving birth to a chromosomally defective child (e.g. with Down Syndrome) increases with the woman’s advancing age. In addition, as women age beyond 35Y there is commonly a progressive diminution in the number of eggs left in the ovaries, i.e. diminished ovarian reserve (DOR). So it is that older women as well as those who (regardless of age) have DOR have a reduced potential for IVF success. Much of this is due to the fact that such women tend to have increased production of LH biological activity which can result in excessive LH-induced ovarian male hormone (predominantly testosterone) production which in turn can have a deleterious effect on egg/embryo “competency”.
      While it is presently not possible by any means, to reverse the age-related effect on the woman’s “biological clock, certain ovarian stimulation regimes, by promoting excessive LH production (e.g. short agonist/Lupron- “flare” protocols, clomiphene and Letrozole), can make matters worse. Similarly, the amount/dosage of certain fertility drugs that contain LH/hCG (e.g. Menopur) can have a negative effect on the development of the eggs of older women and those who have DOR and should be limited.
      I try to avoid using such protocols/regimes (especially) in older women and those with DOR, favoring instead the use of the agonist/antagonist conversion protocol (A/ACP), a modified, long pituitary down-regulation regime, augmented by adding supplementary human growth hormone (HGH). I further recommend that such women be offered access to embryo banking of PGS (next generation gene sequencing/NGS)-selected normal blastocysts, the subsequent selective transfer of which by allowing them to to capitalize on whatever residual ovarian reserve and egg quality might still exist and thereby “make hay while the sun still shines” could significantly enhance the opportunity to achieve a viable pregnancy

  5. Dear Dr. Sher,

    I really need your advice. I have a history of fertility issues. I have undergone 2 fresh and four frozen IVF cycles. I had my blastocysts PGD analyzed. Two day 5 good quality, screened blasts were placed. It resulted in a chemical pregnancy. What should I do? Does this sound like implantation failure?

    • Whenever a patient fails to achieve a viable pregnancy following embryo transfer (ET), the first question asked is why! Was it simply due to, bad luck?, How likely is the failure to recur in future attempts and what can be done differently, to avoid it happening next time?.
      It is an indisputable fact that any IVF procedure is at least as likely to fail as it is to succeed. Thus when it comes to outcome, luck is an undeniable factor. Notwithstanding, it is incumbent upon the treating physician to carefully consider and address the causes of IVF failure before proceeding to another attempt:
      1.Age: The chance of a woman under 35Y of age having a baby per embryo transfer is about 35-40%. From there it declines progressively to under 5% by the time she reaches her mid-forties. This is largely due to declining chromosomal integrity of the eggs with advancing age…”a wear and tear effect” on eggs that are in the ovaries from birth.
      2.Embryo Quality/”competency (capable of propagating a viable pregnancy)”. As stated, the woman’s age plays a big role in determining egg/embryo quality/”competency”. This having been said, aside from age the protocol used for controlled ovarian stimulation (COS) is the next most important factor. It is especially important when it comes to older women, and women with diminished ovarian reserve (DOR) where it becomes essential to be aggressive, and to customize and individualize the ovarian stimulation protocol.
      We used to believe that the uterine environment is more beneficial to embryo development than is the incubator/petri dish and that accordingly, the earlier on in development that embryos are transferred to the uterus, the better. To achieve this goal, we used to select embryos for transfer based upon their day two or microscopic appearance (“grade”). But we have since learned that the further an embryo has advanced in its development, the more likely it is to be “competent” and that embryos failing to reach the expanded blastocyst stage within 5-6 days of being fertilized are almost invariably “incompetent” and are unworthy of being transferred. Moreover, the introduction into clinical practice about a decade ago, (by Levent Keskintepe PhD and myself) of Preimplantation Genetic Sampling (PGS), which assesses for the presence of all the embryos chromosomes (complete chromosomal karyotyping), provides another tool by which to select the most “competent” embryos for transfer. This methodology has selective benefit when it comes to older women, women with DOR, cases of unexplained repeated IVF failure and women who experience recurrent pregnancy loss (RPL).
      3.The number of the embryos transferred: Most patients believe that the more embryos transferred the greater the chance of success. To some extent this might be true, but if the problem lies with the use of a suboptimal COS protocol, transferring more embryos at a time won’t improve the chance of success. Nor will the transfer of a greater number of embryos solve an underlying embryo implantation dysfunction (anatomical molecular or immunologic).Moreover, the transfer of multiple embryos, should they implant, can and all too often does result in triplets or greater (high order multiples) which increases the incidence of maternal pregnancy-induced complications and of premature delivery with its serious risks to the newborn. It is for this reason that I rarely recommend the transfer of more than 2 embryos at a time and am moving in the direction of advising single embryo transfers …especially when it comes to transferring embryos derived through the fertilization of eggs from young women.
      4.Implantation Dysfunction (ID): Implantation dysfunction is a very common (often overlooked) cause of “unexplained” IVF failure. This is especially the case in young ovulating women who have normal ovarian reserve and have fertile partners. Failure to identify, typify, and address such issues is, in my opinion, an unfortunate and relatively common cause of repeated IVF failure in such women. Common sense dictates that if ultrasound guided embryo transfer is performed competently and yet repeated IVF attempts fail to propagate a viable pregnancy, implantation dysfunction must be seriously considered. Yet ID is probably the most overlooked factor. The most common causes of implantation dysfunction are:
      a.A“ thin uterine lining”
      b.A uterus with surface lesions in the cavity (polyps, fibroids, scar tissue)
      c.Immunologic implantation dysfunction (IID)
      d.Endocrine/molecular endometrial receptivity issues
      Certain causes of infertility are repetitive and thus cannot readily be reversed. Examples include advanced age of the woman; severe male infertility; immunologic infertility associated with alloimmune implantation dysfunction (especially if it is a “complete DQ alpha genetic match between partners plus uterine natural killer cell activation (NKa).
      My answer to patients who ask me when is the time to stop undergoing IVF is ….Aside from the weight of the financial burden, the time to stop is when in spite of thorough and comprehensive evaluation, there is no remediable and treatable explanation for repeated failure.
