Dear Dr Sher,
Two questions please:
1) what’s the absolute maximum follicle size on trigger day that should harbour a mature egg?
2) On a short protocol, taking gonal f for the duration, will adding in low dose Menopur (75iu) towards the end help mature eggs better? I am 40 years old. I am aware of your agonist/ antagonist protocol but my Dr will do a short protocol. Either gonal f only or gonal f plus Menopur. What’s better for egg maturation?
1) what’s the absolute maximum follicle size on trigger day that should harbour a mature egg?
A: In my experience, follicles of >23mm rarely harbor “competent” eggs. However,this is not a hard and fast rule because some larger follices sometimes do. I trigger when the leading follicles are 18-22mm.
2) On a short protocol, taking gonal f for the duration, will adding in low dose Menopur (75iu) towards the end help mature eggs better? I am 40 years old. I am aware of your agonist/ antagonist protocol but my Dr will do a short protocol. Either gonal f only or gonal f plus Menopur. What’s better for egg maturation?
A: Since some LH-induced testosterone is needed to optimize egg development, I add 75U Menopur from dy 3 to the day of the trigger. But then, I do not prescribe “short” (“flare”) protocols.

I also suggest that you access the 4th edition of my book ,”In Vitro Fertilization, the ART of Making Babies”. It is available as a down-load through http://www.Amazon.com or from most bookstores and public libraries.
Hi Dr. Sher I am 12 weeks pregnant. I am on clexane and have had one episode of thrombophlebitis in the past . Would this be reason enough to stay on the clexane for the in tire pregnancy or could I come off it aftwr 14 weeks. Thanks
That is a decision for your OB/GYN to make. I probably would test you for thrombophilia and if this was +ve would continue the Clexane throughout and if it w2as negative, would stop Clexane at 10 weeks.

Hi Dr Sher, I’ve had 5 miscarriages (4 of them were natural conceptions and 1 was a PGDed embryo). We got two PGD normal embryos from the last IVF cycle, one miscarried at 5 weeks and the other didn’t implant. All my miscarriages have happened at 4-6 weeks mark except one earlier pregnancy which lasted till 11 weeks and miscarried due to two chromosomal abnormalities. I did one IVF cycle recently which didn’t result in any embryos reaching day 5/6 for PGD biopsy.
Me and my partner had immune testing done at Reprosource lab earlier this year which found the following issues:
– I have only ‘A haplotype’ genes present i.e. KIR AA Haplotype which puts me in the highest risk category
– Complete lack of class II allelle mismatching
– Significant homozygosity of class II alleles (partner is homozygous for all class II alleles)
– I harbour the complete 8.1 extended haplotype (minus HLA-A*01), which includes DRB1*03:01 in combination with DQB1*02:01
– I harbour DQ2 (DQA1*05 with DQB1*02)
– Intermediate levels of anticardiolipin IgM antiphospholipid antibodies (APAs)
– Elevated NKT cell IL-41C ratios and elevated levels of total CD4+ and CD8+ NKT cells.
– Compound heterozygous for MTHFR C677T and A1298C polymorphins
If I get a healthy embryo next cycle, I will be taking a number of drugs for my HRT FET cycle. The drugs include, Neupogen (with stim and with FET), Plaquenil 200mg (1 month prior to transfer), Clexane 40mg, Intralipids every two weeks, prednisone 10mg. The drugs may be adjusted after an immune panel is done at the two week mark from embryo transfer.
Do you agree with the above protocol or would like to suggest something for me which helps the pregnancy? Is there anything else I could do to prepare for my upcoming cycle and FET? I would really appreciate your response. Thank you.
I would like to see the actual results first. If you indeed have NK cell activation by the K-562 target cell test and/or increased TH-1 cytokine activity, I would definitely use Intralipid and steroid therapy and Clexane /Orgalutron but not Plaquenil or Neupogen because of a lack of supportive evidence of efficacy. I would also like to know your husband’s DQ alpha/HLA profile to match with yours, in order help identify an alloimmune implantation issue because if present,that would in my opinion, profoundly affect treatment….see below.
When it comes to reproduction, humans are the poorest performers of all mammals. In fact we are so inefficient that up to 75% of fertilized eggs do not produce live births, and up to 30% of pregnancies end up being lost within 10 weeks of conception (in the first trimester). RPL is defined as two (2) or more failed pregnancies. Less than 5% of women will experience two (2) consecutive miscarriages, and only 1% experience three or more.
Pregnancy loss can be classified by the stage of pregnancy when the loss occurs:
•Early pregnancy loss (first trimester)
•Late pregnancy loss (after the first trimester)
•Occult “hidden” and not clinically recognized, (chemical) pregnancy loss (occurs prior to ultrasound confirmation of pregnancy)
•Early pregnancy losses usually occur sporadically (are not repetitive).
In more than 70% of cases the loss is due to embryo aneuploidy (where there are more or less than the normal quota of 46 chromosomes). Conversely, repeated losses (RPL), with isolated exceptions where the cause is structural (e.g., unbalanced translocations), are seldom attributable to numerical chromosomal abnormalities (aneuploidy). In fact, the vast majority of cases of RPL are attributable to non-chromosomal causes such as anatomical uterine abnormalities or Immunologic Implantation Dysfunction (IID).
Since most sporadic early pregnancy losses are induced by chromosomal factors and thus are non-repetitive, having had a single miscarriage the likelihood of a second one occurring is no greater than average. However, once having had two losses the chance of a third one occurring is double (35-40%) and after having had three losses the chance of a fourth miscarriage increases to about 60%. The reason for this is that the more miscarriages a woman has, the greater is the likelihood of this being due to a non-chromosomal (repetitive) cause such as IID. It follows that if numerical chromosomal analysis (karyotyping) of embryonic/fetal products derived from a miscarriage tests karyotypically normal, then by a process of elimination, there would be a strong likelihood of a miscarriage repeating in subsequent pregnancies and one would not have to wait for the disaster to recur before taking action. This is precisely why we strongly advocate that all miscarriage specimens be karyotyped.
There is however one caveat to be taken into consideration. That is that the laboratory performing the karyotyping might unwittingly be testing the mother’s cells rather than that of the conceptus. That is why it is not possible to confidently exclude aneuploidy in cases where karyotyping of products suggests a “chromosomally normal” (euploid) female.
Late pregnancy losses (occurring after completion of the 1st trimester/12th week) occur far less frequently (1%) than early pregnancy losses. They are most commonly due to anatomical abnormalities of the uterus and/or cervix. Weakness of the neck of the cervix rendering it able to act as an effective valve that retains the pregnancy (i.e., cervical incompetence) is in fact one of the commonest causes of late pregnancy loss. So also are developmental (congenital) abnormalities of the uterus (e.g., a uterine septum) and uterine fibroid tumors. In some cases intrauterine growth retardation, premature separation of the placenta (placental abruption), premature rupture of the membranes and premature labor can also causes of late pregnancy loss.
Much progress has been made in understanding the mechanisms involved in RPL. There are two broad categories:
1.Problems involving the uterine environment in which a normal embryo is prohibited from properly implanting and developing. Possible causes include:
•Inadequate thickening of the uterine lining
•Irregularity in the contour of the uterine cavity (polyps, fibroid tumors in the uterine wall, intra-uterine scarring and adenomyosis)
•Hormonal imbalances (progesterone deficiency or luteal phase defects). This most commonly results in occult RPL.
•Deficient blood flow to the uterine lining (thin uterine lining).
•Immunologic implantation dysfunction (IID). A major cause of RPL. Plays a role in 75% of cases where chromosomally normal preimplantation embryos fail to implant.
•Interference of blood supply to the developing conceptus can occur due to a hereditary clotting disorder known as Thrombophilia.
2.Genetic and/or structural chromosomal abnormality of the embryo.Genetic abnormalities are rare causes of RPL. Structural chromosomal abnormalities are slightly more common but are also occur infrequently (1%). These are referred to as unbalanced translocation and they result from part of one chromosome detaching and then fusing with another chromosome. Additionally, a number of studies suggest the existence of paternal (sperm derived) effect on human embryo quality and pregnancy outcome that are not reflected as a chromosomal abnormality. Damaged sperm DNA can have a negative impact on fetal development and present clinically as occult or early clinical miscarriage. The Sperm Chromatin Structure Assay (SCSA) which measures the same endpoints are newer and possibly improved methods for evaluating.
IMMUNOLOGIC IMPLANTATION DYSFUNCTION
Autoimmune IID: Here an immunologic reaction is produced by the individual to his/her body’s own cellular components. The most common antibodies that form in such situations are APA and antithyroid antibodies (ATA).
But it is only when specialized immune cells in the uterine lining, known as cytotoxic lymphocytes (CTL) and natural killer (NK) cells, become activated and start to release an excessive/disproportionate amount of TH-1 cytokines that attack the root system of the embryo, that implantation potential is jeopardized. Diagnosis of such activation requires highly specialized blood test for cytokine activity that can only be performed by a handful of reproductive immunology reference laboratories in the United States.
Alloimmune IID, i.e., where antibodies are formed against antigens derived from another member of the same species, is believed to be a relatively common immunologic cause of recurrent pregnancy loss.
Autoimmune IID is often genetically transmitted. Thus it should not be surprising to learn that it is more likely to exist in women who have a family (or personal) history of primary autoimmune diseases such as lupus erythematosus (LE), scleroderma or autoimmune hypothyroidism (Hashimoto’s disease), autoimmune hyperthyroidism (Grave’s disease), rheumatoid arthritis, etc. Reactionary (secondary) autoimmunity can occur in conjunction with any medical condition associated with widespread tissue damage. One such gynecologic condition is endometriosis. Since autoimmune IID is usually associated with activated NK and T-cells from the outset, it usually results in such very early destruction of the embryo’s root system that the patient does not even recognize that she is pregnant. Accordingly the condition usually presents as “unexplained infertility” or “unexplained IVF failure” rather than as a miscarriage.
Alloimmune IID, on the other hand, usually starts off presenting as unexplained miscarriages (often manifesting as RPL). Over time as NK/T cell activation builds and eventually becomes permanently established the patient often goes from RPL to “infertility” due to failed implantation. RPL is more commonly the consequence of alloimmune rather than autoimmune implantation dysfunction.
However, regardless, of whether miscarriage is due to autoimmune or alloimmune implantation dysfunction the final blow to the pregnancy is the result of activated NK cells and CTL in the uterine lining that damage the developing embryo’s “root system” (trophoblast) so that it can no longer sustain the growing conceptus. This having been said, it is important to note that autoimmune IID is readily amenable to reversal through timely, appropriately administered, selective immunotherapy, and alloimmune IID is not. It is much more difficult to treat successfully, even with the use of immunotherapy. In fact, in some cases the only solution will be to revert to selective immunotherapy plus using donor sperm (provided there is no “match” between the donor’s DQa profile and that of the female recipient) or alternatively to resort to gestational surrogacy.
DIAGNOSING THE CAUSE OF RPL
In the past, women who miscarried were not evaluated thoroughly until they had lost several pregnancies in a row. This was because sporadic miscarriages are most commonly the result of embryo numerical chromosomal irregularities (aneuploidy) and thus not treatable. However, a consecutive series of miscarriages points to a repetitive cause that is non-chromosomal and is potentially remediable. Since RPL is most commonly due to a uterine pathology or immunologic causes that are potentially treatable, it follows that early chromosomal evaluation of products of conception could point to a potentially treatable situation. Thus I strongly recommend that such testing be done in most cases of miscarriage. Doing so will avoid a great deal of unnecessary heartache for many patients.
Establishing the correct diagnosis is the first step toward determining effective treatment for couples with RPL. It results from a problem within the pregnancy itself or within the uterine environment where the pregnancy implants and grows. Diagnostic tests useful in identifying individuals at greater risk for a problem within the pregnancy itself include:
•Karyotyping (chromosome analysis) both prospective parents
•Assessment of the karyotype of products of conception derived from previous miscarriage specimens
•Ultrasound examination of the uterine cavity after sterile water is injected or sonohysterogram, fluid ultrasound, etc.)
•Hysterosalpingogram (dye X-ray test)
•Hysteroscopic evaluation of the uterine cavity
•Full hormonal evaluation (estrogen, progesterone, adrenal steroid hormones, thyroid hormones, FSH/LH, etc.)
•Immunologic testing to include:
a)Antiphospholipid antibody (APA) panel
b)Antinuclear antibody (ANA) panel
c)Antithyroid antibody panel (i.e., antithyroglobulin and antimicrosomal antibodies)
d)Reproductive immunophenotype
e)Natural killer cell activity (NKa) assay (i.e., K562 target cell test)
f)Alloimmune testing of both the male and female partners
TREATMENT OF RPL
Treatment for Anatomic Abnormalities of the Uterus: This involves restoration through removal of local lesions such as fibroids, scar tissue, and endometrial polyps or timely insertion of a cervical cerclage (a stitch placed around the neck of the weakened cervix) or the excision of a uterine septum when indicated.
Treatment of Thin Uterine Lining: A thin uterine lining has been shown to correlate with compromised pregnancy outcome. Often this will be associated with reduced blood flow to the endometrium. Such decreased blood flow to the uterus can be improved through treatment with sildenafil and possibly aspirin.
Sildenafil (Viagra) Therapy. Viagra has been used successfully to increase uterine blood flow. However, to be effective it must be administered starting as soon as the period stops up until the day of ovulation and it must be administered vaginally (not orally). Viagra in the form of vaginal suppositories given in the dosage of 25 mg four times a day has been shown to increase uterine blood flow as well as thickness of the uterine lining. To date, we have seen significant improvement of the thickness of the uterine lining in about 70% of women treated. Successful pregnancy resulted in 42% of women who responded to the Viagra. It should be remembered that most of these women had previously experienced repeated IVF failures.
Use of Aspirin: This is an anti-prostaglandin that improves blood flow to the endometrium. It is administered at a dosage of 81 mg orally, daily from the beginning of the cycle until ovulation.
Treating Immunologic Implantation Dysfunction with Selective Immunotherapy: Modalities such as IL/IVIg, heparinoids (Lovenox/Clexane), and corticosteroids (dexamethasone, prednisone, prednisolone) can be used in select cases depending on autoimmune or alloimmune dysfunction.
The Use of IVF in the Treatment of RPL
In the following circumstances, IVF is the preferred option:
1.When in addition to a history of RPL, another standard indication for IVF (e.g., tubal factor, endometriosis, and male factor infertility) is superimposed.
2.In cases where selective immunotherapy is needed to treat an immunologic implantation dysfunction.
The reason for IVF being a preferred approach in such cases is that in order to be effective, the immunotherapy needs to be initiated well before spontaneous or induced ovulation. Given the fact that the anticipated birthrate per cycle of COS with or without IUI is at best about 15%, it follows that short of IVF, to have even a reasonable chance of a live birth, most women with immunologic causes of RPL would need to undergo immunotherapy repeatedly, over consecutive cycles. Conversely, with IVF, the chance of a successful outcome in a single cycle of treatment is several times greater and, because of the attenuated and concentrated time period required for treatment, IVF is far safer and thus represents a more practicable alternative
Since embryo aneuploidy is a common cause of miscarriage, the use of preimplantation genetic diagnosis (PGD), with tests such as CGH, can provide a valuable diagnostic and therapeutic advantage in cases of RPL. PGD requires IVF to provide access to embryos for testing.
There are a few cases of intractable alloimmune dysfunction due to absolute DQ alpha matching where Gestational Surrogacy or use of donor sperm could represent the only viable recourse, other than abandoning treatment altogether and/or resorting to adoption. Other non-immunologic factors such as an intractably thin uterine lining or severe uterine pathology might also warrant that last resort consideration be given to gestational surrogacy.
The good news is that if a couple with RPL is open to all of the diagnostic and treatment options referred to above, a live birthrate of 70%–80% is ultimately achievable.

Hi Dr. Sher, I’m 38 and have had ivf 4 times. Two ended in miscarriages at 7weeks. Both pregnancies involved the MDL protocol with v high stimulation (600iu Follistim and 20units of Lupron, for approx 10 days). I had 10 follicles (largest was 19 at trigger), 6 mature and 4 fertilized. E2 was 2500 at trigger. My biggest cycle failure was low dose follistim and clomid (no viable embryos by day 3). I’m warming up to Egg donation but wanted to get your thoughts on the MDL protocol for 35+ and whether you think an alternative protocol might be worth a try. Thank you in advance! Naomi
Hi Naomi,
I personally never use MDL protocols for reasons you will find in the articles below. However there are many who feel differently and candidly, I doubt that the protocol used was responsible for your losses. Please read below and consider the possibility that there might be other implantation factors because if there are and you do not address these, it could impact future treatments regardless of stimulation methodology.

Given the fact that the anticipated birthrate per cycle of COS with or without IUI is at best about 15%, it follows that short of IVF, to have even a reasonable chance of a live birth, most women with immunologic causes of RPL would need to undergo immunotherapy repeatedly, over consecutive cycles. Conversely, with IVF, the chance of a successful outcome in a single cycle of treatment is several times greater and, because of the attenuated and concentrated time period required for treatment, IVF is far safer and thus represents a more practicable alternative
Since embryo aneuploidy is a common cause of miscarriage, the use of preimplantation genetic diagnosis (PGD), with tests such as CGH, can provide a valuable diagnostic and therapeutic advantage in cases of RPL. PGD requires IVF to provide access to embryos for testing.
There are a few cases of intractable alloimmune dysfunction due to absolute DQ alpha matching where Gestational Surrogacy or use of donor sperm could represent the only viable recourse, other than abandoning treatment altogether and/or resorting to adoption. Other non-immunologic factors such as an intractably thin uterine lining or severe uterine pathology might also warrant that last resort consideration be given to gestational surrogacy.
The good news is that if a couple with RPL is open to all of the diagnostic and treatment options referred to above, a live birthrate of 70%–80% is ultimately achievable.

I am 31 years old and found out after a HSG it was found that one of my Fallopian tubes was blocked. I was therefore advised by my clinic to go for IVF.
I had all the initial tests and was told I was a good candidate. I am using good quality donor sperm from a clinic (the donor sperm has apparently resulted in previous pregnancies for other people).
My first round of IVF resulted in 16 eggs. I had mild OHSS but one was transferred after 3 days and two made it to blastocyst stage and were frozen. The fresh cycle and both FET failed.
I am now on my second round of IVF with a slightly lower dose of Gonal F which meant I didn’t have any OHSS. I had 9 eggs, 3 made it to blastocyst stage. I had one transferred and two frozen. I am currently on day eight after a 5 day transfer but have just noticed spotting. Is it too late to be getting implementation spotting?
Each time I have a transfer, I seem to get what I think is implementation symptoms (after one transfer, I had really, really bad pains that made me stop whilst I was walking. I get twinges and nausea and flushes) but still nothing happens.
I am concerned that my clinic that I go to doesn’t monitor my hormone levels during the IVF, for example, I am taking progesterone but each cycle it hasn’t held off my period (which I thought it was supposed to) and so I am concerned that maybe my levels are too low? My clinic said not to worry about that?
I am really just after some advice as it is heartbreaking at the end of each two week wait getting bad news.
Thanks for your time.
It is possible, in spite of the spotting that you have implanted and on your wsay to a healthy pregnancy. However, if not…then consider the following:
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.
