Hi Dr,
1. can FSH be too low for IVF success (FSH is 2.1 on day 2 following BCP, age is 36, LH is 2.3, AMH is 1.5ng/l)?
2. in your experience, does Antagonist (after BCP) produce more eggs than long lupron or AACP (given the hormone stats listed above)?
3. If going for the long lupron/AACP with no BCP prior, how can one avoid developing a cyst after ovulation?
Merci Beacoup!
1. can FSH be too low for IVF success (FSH is 2.1 on day 2 following BCP, age is 36, LH is 2.3, AMH is 1.5ng/l)?
A: No, but the dosage and stimulation regime would need to be adjusted accordingly.
2. in your experience, does Antagonist (after BCP) produce more eggs than long lupron or AACP (given the hormone stats
A: In my opinion, with your AMH being reduced (DOR)…yes!
3. If going for the long lupron/AACP with no BCP prior, how can one avoid developing a cyst after ovulation?

A: No!
Geoff Sher
Thank you! so What stim protocol would you recommend? My RE is planning to use the antagonist after 21 days of BCP. Meds will be gonal-f 300iu and menopur 75 iu. Do you agree that this will give me maximum number of eggs and quality?
Dear Dr Sher,
I am 34 and have been diagnosed with diminished ovarian reserve (FSH 19, AMH 0.5, no antral follicles seen). I had ovarian torsion at age 23 due to an abnormal fallopian tube developmental remnant. I don’t have PCOS or any other issues. Genetic testing and karyotyping was normal.
My partner has Kallmann’s syndrome and so my situation was uncovered during evaluation after he had undergone fertility inducing hormonal treatments for two years. He has never had a sperm count above 1 million/ml despite tweaks to his medication.
My fertility specialist reluctantly went ahead with two cycles of stimulation using the late antagonist protocol (300U puregon, orgalutran from day 6 and HCG trigger). Each cycle only resulted in two follicles, of which only 1/4 of these follicles yielded an egg, which abnormally divided on Day 0/1 and was discarded on Day 3.
My fertility specialist now thinks that egg donation is the only way forward and naturally we are devastated and lost after such a prolonged and traumatic journey.
Do you have any advice?
I would really like to know how your husband has been treated. The Kallman’s should be amenable to gonadotropin/hCG treatment.
Respectfully, as for you, given your age, in my opinion, you likely would not need an OD at this stage I think everything revolves around the precise protocol used. Consider the following:
In my opinion, the protocol used for ovarian stimulation, against the backdrop of age, and ovarian reserve are the drivers of egg quality and egg quality is the most important factor affecting embryo “competency”.
Women 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 effect of DOR, certain ovarian stimulation regimes, by promoting excessive LH production (e.g. short agonist/Lupron- “flare” protocols, clomiphene and Letrozole), can in my opinion, 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 women 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 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

Hello Dr Sher, I am 35 years old with 2 daughters and no previous miscarriages. I have completed 2 egg retrieval cycles for IVF as my husband had a vasectomy, so we did aspiration ( he is 48 yr old). The first cycle I had one normal embryo after PGS, it was transferred resulting in pregnancy 14 days later. On day 16 I lost this embryo, my first ever miscarriage, with only normal embryo. The second cycle resulted in 2 abnormal blastocyst, that after PGS came back one with mosaic monosomy 17, and one with mosaic partial monosomy, trisomy 22. I also have one from first cycle that is mosaic monosomy 6. What are your thoughts on a transfer with these 3?
Human embryo development occurs through a process that encompasses reprogramming, sequential cleavage divisions and mitotic chromosome segregation and embryonic genome activation. Chromosomal abnormalities may arise during germ cell and/or pre-implantation embryo development, and represents a major cause of early pregnancy loss. About a decade ago, I and an associate, Levent Keskintepe Ph.D were the first to introduce full embryo karyotyping (identification of all 46 chromosomes) through preimplantation genetic sampling (PGS) as a method by which to selectively transfer only euploid embryos (i.e. those that have a full component of chromosomes) to the uterus. We subsequently reported on a 2-3 fold improvement in implantation and birth rates as well as a significant reduction in early pregnancy loss, following IVF. Since then PGS has grown dramatically in popularity such that it is now widely used throughout the world.
Most IVF programs that offer PGS services, require that all participating patients consent to all their aneuploid embryos (i.e. those with an irregular quota of chromosomes) be disposed of. However, there is now growing evidence to suggest that following embryo transfer, some aneuploid embryos will in the process of ongoing development, convert to the euploid state (i.e. “autocorrection”) and then go on to develop into chromosomally normal offspring. In fact, I am personally aware of several such cases occurring within our IVF network. So clearly , summarily discarding all aneuploid embryos as a matter of routine we are sometimes destroying some embryos that might otherwise have “autocorrected” and gone on to develop into normal offspring.
Thus by discarding aneuploid embryos the possibility exists that we could be denying some women the opportunity of having a baby. This creates a major ethical and moral dilemma for those of us that provide the option of PGS to our patients. On the one hand, we strive “to avoid knowingly doing harm” (the Hippocratic Oath) and as such would prefer to avoid or minimize the risk of miscarriage and/or chromosomal birth defects and on the other hand we would not wish to deny patients with aneuploid embryos, the opportunity to have a baby.
The basis for such embryo “autocorrection” lies in the fact that some embryos found through PGS-karyotyping to harbor one or more aneuploid cells (blastomeres) will often also harbor chromosomally normal (euploid) cells (blastomeres). The coexistence of both aneuploid and euploid cells coexisting in the same embryo is referred to as “mosaicism.” As stated, some mosaic embryos will In the process of subsequent cell replication convert to the normal euploid state (i.e. autocorrect)
It is against this background, that an ever increasing number of IVF practitioners, rather than summarily discard PGS-identified aneuploid embryos are now choosing to cryobanking (freeze-store) certain of them, to leave open the possibility of ultimately transferring them to the uterus. In order to best understand the complexity of the factors involved in such decision making, it is essential to understand the causes of embryo aneuploidy of which there are two varieties:
1.Meiotic aneuploidy” results from aberrations in chromosomal numerical configuration that originate in either the egg (most commonly) and/or in sperm, during preconceptual maturational division (meiosis). Since meiosis occurs in the pre-fertilized egg or in and sperm, it follows that when aneuploidy occurs due to defective meiosis, all subsequent cells in the developing embryo/blastocyst/conceptus inevitably will be aneuploid, precluding subsequent “autocorrection”. Meiotic aneuploidy will thus invariably be perpetuated in all the cells of the embryo as they replicate. It is a permanent phenomenon and is irreversible. All embryos so affected are thus fatally damaged. Most will fail to implant and those that do implant will either be lost in early pregnancy or develop into chromosomally defective offspring (e.g. Down syndrome, Edward syndrome, Turner syndrome).
2.“Mitotic aneuploidy” occurs when following fertilization and subsequent cell replication (cleavage), some cells (blastomeres) of a meiotically euploid early embryo mutate and become aneuploid. This is referred to as mosaicism. Thereupon, with continued subsequent cell replication (mitosis) the chromosomal make-up (karyotype) of the embryo might either comprise of predominantly aneuploid cells or euploid cells. The subsequent viability or competency of the conceptus will thereupon depend on whether euploid or aneuploid cells predominate. If in such mosaic embryos aneuploid cells predominate, the embryo will be “incompetent”). If (as is frequently the case) euploid cells prevail, the mosaic embryo will be “competent” and capable of propagating a normal conceptus.
Since some mitotically aneuploid (“mosaic”) embryos can, and indeed do “autocorrect’ while meiotically aneuploid embryos cannot, it follows that an ability to differentiate between these two varieties of aneuploidy would be of considerable clinical value. And would provide a strong argument in favor of preserving certain aneuploid embryos for future dispensation.
Aneuploidy, involves the addition (trisomy) or subtraction (monosomy) of one chromosome in a given pair. As previously stated, some aneuploidies are meiotic in origin while others are mitotic “mosaics”. Certain aneuploidies involve only a single, chromosome pair (simple aneuploidy) while others involve more than a single pair (i.e. complex aneuploidy). Aside from monosomy involving absence of the y-sex chromosome (i.e. XO) which can resulting in a live birth (Turner syndrome) all monosomies involving autosomes (non-sex chromosomes) are lethal and will not result in viable offspring). Some autosomal meiotic aneuploidies, especially trisomies 13, 18, 21, can progress to viable, but severely chromosomally defective babies. All other meiotic autosomal trisomies will almost invariably, either not attach to the uterine lining or upon attachment, will soon be rejected. All forms of meiotic aneuploidy are irreversible while mitotic aneuploidy (“mosaicism) often autocorrects in the uterus. Most complex aneuploidies are meiotic in origin and will almost invariably fail to propagate viable pregnancies.
There is presently no microscopic or genetic test that can reliable differentiate between meiotic and mitotic aneuploidy. Notwithstanding this, the fact that some “mosaic” embryos can autocorrect in the uterus, makes a strong argument in favor of transferring aneuploid of embryos in the hope that the one(s) transferred might be “mosaic” and might propagate viable healthy pregnancies. On the other hand, it is the fear that embryo aneuploidy might result in a chromosomally abnormal baby that has led many IVF physicians to strongly oppose the transfer of any aneuploid embryos to the uterus.
While certain meiotic aneuploid trisomies (e.g. trisomies 13, 18, & 21) can and sometimes do result in chromosomally defective babies, no other meiotic autosomal trisomies can do so. Thus the transfer of trisomic embryos in the hope that one or more might be mosaic, should exclude the use of embryos with trisomies 13, 18 or 21. Conversely, no autosomal monosomic embryos are believed to be capable of resulting in viable pregnancies, thereby making the transfer of autosomally monosomic embryos, in the hope that they are “mosaic”, a far less risky proposition. Needless to say, if such action is being contemplated, it is absolutely essential to make full disclosure to the patient (s) , and to insure the completion of a detailed informed consent agreement which would include a commitment by the patient (s) to undergo prenatal genetic testing aimed at excluding a chromosomal defect in the developing baby and/or a willingness to terminate the pregnancy should a serious birth defect be diagnosed.
Hope this helps!

Dr Sher,
Is it safe to take a 10 hr international flight 2-3 weeks after embryo transfer?
Thank you.
Absolutely safe!

Hello Dr. Sher,
I was at a previous SIRM clinic and trasnferred 2 fresh and bfn, cycled again and froze all with he leftover from the fresh cycle. I then did 3 months of Lupron Depot. I transferred 3 frozen embryos with Intralipids and scraping which resulted in one baby.
I moved and so i tried a different SIRM clinic where i transferred 2 frozen (dr did not feel comfortable transferring 3) with intralipids(dr does not do scraping) which resulted in a positive and baby having heartbeat at 6wks but then heart stopped by next visit. I had a D&C and im having the tissue tested for Chromosomal abnormalities but am stuck as how to proceed. PGD testing will make it extremely expensive since this is all out of pocket . What are your thoughts on how to proceed as i have frozen embryos remaining.
I would not do PGD on frozen embryos. In my opinion, the thaw–freeze–thaw and transfer needed would be too traumatic on the embryos. If you do PGS it should in my opinion be done on biopsies taken from fresh blastocysts. I also do not believe in any benefit from the endometrial scrape!
Good luck!
Geoff Sher
