  1. Hi Dr. Sher,

    I wanted to update my HCG levels after my transfer on April 23rd:

    5dpt 27
    7dpt 123
    10dpt 751
    12dpt 1748
    17dpt 14146

    Does it still look good? I only transfer single embryo does it look like it split?

    Thank you!

    • I don’t think it split…but it looks quite promising!

  2. Hi,
    I have DOR with an amh of 1.0. I am on day 6 of my stimulation drugs and I have 17 follicles. The technician commented that they were not growing quite yet. Does this put me at risk of being a poor responder and is it okay that my body is taking longer to grow the eggs. Thank you!

    • The duration of stimulation is not that important. Time will tell.

      The protocol used fort ovarian stimulation could however, be a determining factor.

      Good luck!

  3. Dear Dr Sher
    Thank you for your extremely informative site and responses to people’s questions, it is a very valuable and generous resource.

    I just turned 44 years old this month and have tried IVF 8 times over the last three years at a clinic in Denmark.
    I had a laparoscopy for mild endometriosis in 2011 from which they don’t see scarring. I have extremely low testosterone levels, DHEA is fine, AMH was 7.9 in 2018 and deemed adequate for my age. I had severe vitamin D deficiency in December, now corrected. No problems with my partner’s sperm quality.
    In each cycle I have had 3-7 eggs collected and mostly 2 embryos transferred on day 2. I had one chemical pregnancy and have one blastocyst frozen at day 6/7.

    We would like to do one more cycle whilst we put ourselves on the waiting list for egg donation, and I hoped you could advise us. When we started IVF I asked the clinic if we could do several collections in a row and freeze them, before transferring any (I didn’t know that that was actually a recognised process, it just seemed to me a logical thing to do as I was already quite old), but they didn’t think it was worth the risk of defrosting. So I slightly regret that I didn’t know about that, though perhaps you would say that would not have been the right path anyway.

    We feel that our results were suddenly better once we switched to the short protocol with fostimon and fyrmedal.

    Is there anything else you would suggest for this last attempt?

    My protocol details below. Many thanks in advance!

    • Age, diminished ovarian reserve and the protocols used for ovarian stimulation are the most likely issues here. In addition, endometriosis and a possible immunologic implantation dysfunction potentially linked to endometriosis could also be factors. I think we should talk before you proceed any further.

      A: Diminished Ovarian Reserve (DOR)

      It is primarily the egg (rather than the sperm) that determines the chromosomal integrity (karyotype) of the embryo, the most important determinant of egg/embryo competency”. A “competent” egg is therefore one that has a normal karyotype and has the best potential to propagate a “competent” embryo. In turn, a “competent embryo is one that possesses the highest potential to implant and develop into a normal, healthy, baby.
      When it comes to reproductive performance, humans are the least efficient of all mammals. Even in young women under 35y, at best only 1 out of 2 eggs are chromosomally numerically normal (euploid). The remained have an irregular number of chromosomes (aneuploid) and are thus “incompetent”. The incidence of egg aneuploidy increases with age such by age 39 years, 3 in 4 are competent, and by the mid-forties, less 8 to 9 out of 10 are aneuploid. The fertilization of an aneuploid egg will inevitably lead to embryo aneuploid and an aneuploid embryo cannot propagate a normal pregnancy
      Within hours of the spontaneous pre-ovulatory luteinizing hormone (LH) surge, and also following administration of the human chorionic gonadotropin (hCG) “trigger” shot (given to induce ovulation after ovarian stimulation with fertility drugs), the egg embarks on a rapid maturational process that involves halving of its 46 chromosomes to 23. During this process, (known as meiosis) 23 chromosomes are retained within the nucleus of the egg while the remaining (now redundant) 23are expelled, enveloped by a thin membrane. This small structure comes to lie immediately below the “shell” of the egg (the zona pellucida) and is known as the 1st polar body or PB-1. The spermatozoon, in the process of its maturation also undergoes meiosis at which time it too reduces its chromosomes by half. Thus in the process of fertilization the sperm divides into two separate functional gametes, each containing 23 chromosomes such that with subsequent fertilization, the 23 chromosomes in the egg, fuse with the 23 chromosomes of the mature sperm resulting in the development of an embryo that has 46 chromosomes (the normal human genome) comprising a combination of the genetic material from both partners. For the embryo to have exactly 46 chromosomes (the euploid number), both the mature egg and mature spermatozoon must contain exactly 23 chromosomes. Only euploid embryos are “competent” (capable of developing into healthy babies). Those with an irregular number of chromosomes (aneuploid embryos) are “incompetent” and are incapable of developing into healthy babies. While embryo “incompetence” can result from either egg or sperm aneuploidy, it usually stems from egg aneuploidy. However, in cases of moderate or severe male factor infertility, the sperm’s contribution to aneuploidy of the embryo increases significantly.
      While embryo ploidy (numerical chromosomal integrity) is not the only determinant of its “competency, it is by far the most important and in fact is rate-limiting factor in human reproduction. It is causal in most cases of “failed implantation” which in turn is responsible for most cases of failed IVF. It causes early miscarriages and is responsible for many chromosomal birth defects such as X-monosomy and Down’s syndrome. . In most cases, embryos that develop too slowly as well as those that grow too fast (i.e. ones that by day 3 post-fertilization comprise fewer than 6 cells or more than 9 cells) and/or embryos that contain a large amount of cell debris or “fragments” are usually aneuploid and are thus “incompetent”. Additionally, embryos that fail to survive in culture to the blastocyst stage are also almost always aneuploid/”incompetent”. At a certain point in the later stage of a woman’s reproductive career, the number of remaining eggs in her ovaries falls below a certain threshold, upon which she is unable to respond optimally to fertility drugs. Often times this is signaled by a rising day 3 blood follicle stimulating hormone (FSH) level. Such women with diminishing ovarian reserve produce fewer eggs in response to ovarian stimulation. While diminished ovarian reserve is most commonly encountered in women over 40 years of age it can and indeed sometimes does occur in much younger women. A few important (but often overlooked concepts should be considered in this regard: 1. Age: It is advancing chronologic age and NOT declining ovarian reserve (as evidenced by abnormal blood AMH or FSH that results in an increased incidence of egg/embryo “incompetence” due to aneuploidy 2. DOR: The ovaries and developing eggs of women with diminished ovarian reserve (regardless of age) are highly susceptible to the adverse effect of excessive Luteinizing Hormone (LH)-induced overproduction of male hormones (mainly testosterone). A little testosterone produced by the ovary promotes normal follicle growth and orderly egg development but too much testosterone has the opposite effect. That is why (especially in women with diminished ovarian reserve who often have high LH and increased ovarian testosterone production , the use of ovarian stimulation protocols that fail to down-regulate LH production prior to initiating stimulation with gonadotropins, often prejudices egg/embryo quality and IVF outcome. Simply stated, while age is certainly the most important factor in determining the incidence of egg/embryo aneuploidy, women with diminished ovarian reserve (regardless of their age), unless they receive customized/individualized protocols of ovarian stimulation are less likely to propagate euploid (competent) eggs/embryos.
      Selection of the ideal protocol for controlled ovarian stimulation: While NOTHING can be done to lower the incidence of age related aneuploidy, it is indeed possible to avoid a further increase in egg/embryo aneuploidy by individualizing the protocols of ovarian stimulation used.
      •My preferred protocols for women who have relatively normal ovarian reserve:
      a)The conventional long pituitary down regulation protocol: BCP are commenced early in the cycle and continued for at least 10 days. Starting 3 days before the BCP is to be discontinued, it is overlapped with an agonist such as Lupron 10U daily for three (3) days and continued until menstruation begins (which should ensue within 5-7 days of stopping the BCP). At that point an US examination is done along with a baseline measurement of blood estradiol to exclude a functional ovarian cyst. Simultaneously, the Lupron dosage is reduced to 5U daily and an FSH-dominant gonadotropin such as Follistim, Puregon or Gonal-f daily is commenced for 2 days. On the 3rd day the gonadotropin dosage is reduced and a small amount of daily menotropin (Menopur 75U daily) is added. Daily ultrasound and blood estradiol measurements are done starting on the 7th or 8th day of gonadotropin administration and continued until daily ultrasound follicle assessments indicate that most follicles have fully developed. At this point egg maturation is “triggered” using an intramuscular injection of 10,000U hCG. And an egg retrieval is scheduled for 36h later.
      b)The agonist/antagonist conversion protocol (A/ACOP): This is essentially the same as the conventional long down regulation protocol (as above), except that with the onset of post-BCP menstruation, the agonist is supplanted by daily administration of a GnRH antagonist (e.g. Ganirelix, Cetrotide or Orgalutron) at a dosage of 125mcg daily until the day of the hCG trigger
      •My preferred protocol for women who have relatively diminished ovarian reserve (DOR):
      When it comes to women who have DOR I favor the use of the A/ACP, adding supplementary human growth hormone (HGH). In some cases where the DOR is regarded as severe, I also augment the process with estrogen priming, preferring twice weekly intramuscular administration of estradiol valerate (Delestrogen), starting with the commencement of antagonist injection and continuing for 1 week before commencing gonadotropins and continued until the hCG “trigger. I further recommend that such women be offered access to preimplantation genetic screening (PGS) for4 embryo selection and in some cases, for embryo banking (stockpiling). This is followed in a later hormone replacement cycle with the selective transfer of up to two (2) PGS-normal, euploid blastocysts. In this way we are able to capitalize on whatever residual ovarian reserve and egg quality might still exist and thereby “make hay while the sun still shines” , significantly enhancing the opportunity to achieve a viable pregnancy
      •The following Ovarian stimulation protocols are in my opinion best avoided in women with DOR:
      a)Microdose agonist (e.g. Lupron) “flare” protocols
      b)High doses of LH/hCG-containing fertility drugs (E.G. Menopur).
      c)Protocols that incorporate supplementation with male hormones (e.g. testosterone)
      d)Supplementation with DHEA
      e)Clomiphene citrate or Letrozole which cause an elevation in LH and thus increase ovarian male hormone (testosterone and androstenedione output.
      f)“Triggering” egg maturation using too low a dosage of hCG (e.g. 5,000U rather than 10,000U) or Ovidrel e.g. 250mcg of Ovidrel rather than 500mcg)
      g)“Triggering” women who have large numbers of follicles using an agonist such as Lupron, Superfact or Buserelin.
      •Preimplantation Genetic Screening (PGS):
      The introduction of preimplantation genetic screening (PGS) for the first time permits identification of all the chromosomes in the egg and embryo such that we can now far better identify “competent” (euploid) embryos for selective transfer to the uterus. This vastly improves the efficiency and success of the IVF process. This additional tool has better equipped us to manage cases with DOR. In my opinion, next generation gene sequencing (NGS), currently represents the most reliable method for performing PGS

      B: Endometriosis

      More than half of women who have endometriosis harbor antiphospholipid antibodies (APA) that can compromise development of the embryo’s root system (trophoblast). In addition and far more serious, is the fact that in about one third of cases endometriosis, regardless of its severity is associated with NKa and cytotoxic uterine lymphocytes (CTL) which can seriously jeopardize implantation. This immunologic implantation dysfunction (IID) is diagnosed by testing the woman’s blood for APA, for NKa (using the K-562 target cell test or by endometrial biopsy for cytokine activity) and, for CTL (by a blood immunophenotype). Activated NK cells attack the invading trophoblast cells (developing “root system” of the embryo/early conceptus) as soon as it tries to gain attachment to the uterine wall. In most cases, this results in rejection of the embryo even before the pregnancy is diagnosed and sometimes, in a chemical pregnancy or an early miscarriage. As such, many women with endometriosis, rather than being infertile, in the strict sense of the word, often actually experience repeated undetected “mini-miscarriages”.
      Women who harbor APA’s often experience improved IVF birth rates when heparinoids (Clexane/Lovenox) are administered from the onset of ovarian stimulation with gonadotropins until the 10th week of pregnancy. NKa is treated with a combination of Intralipid (IL) and steroid therapy: Intralipid (IL) is a solution of small lipid droplets suspended in water. When administered intravenously, IL provides essential fatty acids, linoleic acid (LA), an omega-6 fatty acid, alpha-linolenic acid (ALA), an omega-3 fatty acid.IL is made up of 20% soybean oil/fatty acids (comprising linoleic acid, oleic acid, palmitic acid, linolenic acid and stearic acid) , 1.2% egg yolk phospholipids (1.2%), glycerin (2.25%) and water (76.5%).IL exerts a modulating effect on certain immune cellular mechanisms largely by down-regulating NKa.
      The therapeutic effect of IL/steroid therapy is likely due to an ability to suppress pro-inflammatory cellular (Type-1) cytokines such as interferon gamma and TNF-alpha. IL/steroids down-regulates NKa within 2-3 weeks of treatment the vast majority of women experiencing immunologic implantation dysfunction. In this regard IL is just as effective as Intravenous Gamma globulin (IVIg) but at a fraction of the cost and with a far lower incidence of side-effects. Its effect lasts for 4-9 weeks when administered in early pregnancy.
      The toxic pelvic environment caused by endometriosis, profoundly reduces natural fertilization potential. As a result normally ovulating infertile women with endometriosis and patent Fallopian tubes are much less likely to conceive naturally, or by using fertility agents alone (with or without intrauterine (IUI) insemination. The only effective way to bypass this adverse pelvic environment is through IVF. I am not suggesting here that all women who have endometriosis require IVF! Rather, I am saying that in cases where the condition is further compromised by an IID associated with NKa and/or for older women(over 35y) who have diminished ovarian reserve (DOR) where time is of the essence, it is my opinion that IVF is the treatment of choice.

      C: Why did IVF Fail?

      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 15y 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
      e.Ureaplasma Urealyticum (UU) Infection of cervical mucous and the endometrial lining of the uterus, can sometimes present as unexplained early pregnancy loss or unexplained failure following intrauterine insemination or IVF. The infection can also occur in the man, (prostatitis) and thus can go back and forth between partners, with sexual intercourse. This is the reason why both partners must be tested and if positive, should be treated contemporaneously.
      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).

  4. Hello Dr. Sher,

    I recently went back to my RE to move forward with a PGS tested frozen embryo transfer. Dr wants to do genetic testing bloodwork on my husband and me. Do you recommend doing the genetic testing bloodwork even though we have a pgs tested embryo?
    Thank you kindly

    • Genetic abnormalities are different from chromosomal abnormalities. It depends on what your doctor is looking for. Discuss with him/her.

  5. Hello- I am 42 yrs old. I have very low Amh . I do have a 7 yr old son that took 5 iuis to create. We have been trying every since we had him. My husband and I have had 6 clomid iui’s, 6 injectable iuis and then moved on to Ivf. Our first resulted in 1 egg that didn’t fertilize. The second ivf we transferred 3 embryos and UT resulted in a chemical pregnancy. The 3rd we transferred 4 embryos and nothing took. We then moved on to donor eggs. Our first FET we transferred 2 and it failed. We just had a transfer on Friday 5/7 with a hcg wash on 5/6. On transfer day my E2 was 280 and my p4 was 20.0. I went for mid cycle bloodwork today and my E2 dropped to 167 and P4 went up to 24.4. I did a home pregnancy test yesterday and I got a very faint line. Today I did anther and it is slightly darker. Should I be worried that my estrogen dropped and this will most likely be a chemical pregnancy again? My pregnancy bloodwork isn’t until this Monday.
