    Question re: ideal protocol for 40 yo woman with low AMH/

    Hello Dr Sher I have diminished ovarian reserve. My AMH 2 yrs ago was 0.36. Its likely even lower now :( I have been a poor responder to high dose IVF with gonal-f (450 units) and menopur 150 units. Prior… — Yvette R.

    Dr. Geoffrey Sher answered

    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,…

  4. IVF Failure & Pregnancy Loss

    How to improve next time

    Hi Dr Sher. I'm 33 yrs old, and my husband is 40. I developed uterine scarring in 2019 after a D&C from an incomplete miscarriage. I was cleared to try again after several hysteroscopies. After 2 failed IVFs, I finally… — Rashida J.

    Dr. Geoffrey Sher answered

    I agree with you! Clearly you had post=pregnancy endometritis that compromised the basal (germinal layer) of you endometrium. This could absolutely explain your implantation dysfunction.Unfortunate, this kind of injury is often refractory to treatment but it is worth a try with vaginal Viagra and Estradiol to see if…

    What next?

    Hi Dr Sher, we are a couple aged 35 and 34. We had 2 natural pregnancies which resulted in first trimester miscarriages. We later found out that my husband has balanced translocation and I have low amh of about 0.8ng/ml… — Sofia C.

    Dr. Geoffrey Sher answered

    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?.…

    Dr. Geoffrey Sher answered

    I do not believe that this is likely to be due to an intrinsic egg issue. It is likely due to the type of protocol used and/or the type and typing/dosage/timing of the "trigger". We really need to talk. I suggest you call my assistant, Patti Converse at…

  8. Third-Party Reproduction

    Thin endometrium 3 years after successful egg donor pregnancy

    Dr. Geoffrey Sher answered

    It is possible that with established menopause, the chronically low estradiol has suppressed endometrial estrogen receptors, rendering the lining refractory to short-term estrogen stimulation. In my opinion you s might try a few months of cyclical estrogen/progesterone therapy to try and prime the endometrium (reawaken estrogen receptor response).…

    Dr. Geoffrey Sher answered

    Respectfully, In my opinion neither mini-IVF nor clomiphene is good in women with diminished ovarian reserve. 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…

    Dr. Geoffrey Sher answered

    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…
