  1. Uterine & Endometrial Health

    Uterine Microbiome

    Hi Dr Sher Uterine testing (via menstrual blood collection) has continuously shown very high presence of Gardnerella Vaginalis. Despite antibiotic treatment, it continues to reappear as Lactobacillus levels have only been ‘not detectable’ or ‘very low’. Use of oral lactobacillus… — Samantha L.

    Pregnancy Loss, IVF & Immunologic Testing

    Hi Dr. Sher, I live in Toronto and have had 2 chemicals and one miscarriage within the span of 5 months. I used Letrozole to ovulate with the first 2 pregnancies, but I ovulated naturally with the third pregnancy. For… — Catherine B.

    Dr. Geoffrey Sher answered

    Based upon your representation, this sounds very suggestive of an embryo implantation dysfunction.However, to provide an authoritative opinion we should talk. If I turn out to be correct and you are not treated appropriately to counter the implantation dysfunction, you will very likely experience the same over and…

  3. Early Pregnancy & hCG

    IVF Treatment / B.HCG

    Dear Dr. Sher, Good day. I want to refer to my situation regarding my IVF treatment here in Dubai UAE. I did my frozen ET last July 23, 2024. after 12 days I did my B.HCG the result was 52.9… — Mariam C.

    Dr. Geoffrey Sher answered

    This is a chemical pregnancy. Going through IVF is a major investment, emotionally, physically, and financially, for every patient or couple. One of the most crucial moments is receiving the result of the blood test for human chorionic gonadotropin (hCG) pregnancy. It's a big deal! The days after…

  4. Egg Health & Ovarian Reserve

    CoQ10

    I am 43 years old with AMH of 3. My egg retrieval was yesterday. My HCG trigger did not absorb after 7 days of Stims and no priming starting on day 5 of my period. I was given 150 meno… — Kristin H.

    Dr. Geoffrey Sher answered

    The COQ10 likely had nothing to do with your follicle development. However, the protocol used for ovarian stimulation and/or its implementation, probably underlies your issue.We should talk: Please call my assistant, Patti Converse (702-533-2691 and set up an online consultation with me.

  5. Immunology & Implantation

    Immune Testing

    I am 37 yo with dx of DOR. Have banked 7 PGTa normal embryos via 3 retrievals. 4 medicated FET (on dexamethasone, ASA 81mg, intralipids 1 week prior to transfer) resulted in chemical pregnancies. Question now on possible immune/ alloimmune… — Is S.

  6. Egg Health & Ovarian Reserve

    Transfer at age 45

    Hello, Im am 45 . We have male factor infertility and in 2012 we got pregnant on our first try with a non medicated IUI using donor sperm. I had a healthy baby boy via C section. He is 11.5… — Emily B.

    Dr. Geoffrey Sher answered

    You clearly have diminished ovarian reserve. This in conjunction with your age (45y) makes the chance of successful pregnancy using your own eggs, very improbable. You actually need IVF with egg donation. Also, IUI has less than a 1:80 chance of success for you. If in spite of…

  7. Egg Health & Ovarian Reserve

    Protocol

    Hi, I am 44 with an Amh between 2.3 and 3 ng/ml, we had failed Icsis but always blastocysts. Would you also recommend the protocol you normally describe here or at the egg whisperer podcast in my case? Last year… — M M.

    Dr. Geoffrey Sher answered

    Your normal AMH at 44y comes as a surprise but that is decidedly in your favor. However, independently, age impacts egg "competency" and it is the egg (rather than the sperm that is most important in propagating normal "competent" embryos. Age should never be a barrier to hope…

  8. Early Pregnancy & hCG

    Abnormal placentation and immune pr

    Hi Dr. Sher, I've gone through 2 egg retrievals and 5 fets, gotten pregnant twice and had 2 miscarriages in the last year and a half. The miscarriage last year at 6 weeks happened at home and I had a… — Bethany D.

    Dr. Geoffrey Sher answered

    I aplaud your looking in to immunologic implantation dysfunction (IID) as a possible reason for your losses. If you indeed do have an autoimmune/alloimmune IID link It might not have been comprehensively assessed. There are only a hand-full of laboratories in the world that can do the required…

  12. Uterine & Endometrial Health

    Viagra

    Can viagra help thicken uterus lining for FET preparation? Does it impact WOI ? — Catherine H.

    Dr. Geoffrey Sher answered

    Back in 1989, I conducted a study that examined how the thickness of a woman's uterine lining, known as the endometrium, affected the successful implantation of embryos in IVF patients. The study revealed that when the uterine lining measured less than 8mm in thickness by the day of…

    Dr. Geoffrey Sher answered

    _ When it comes to reproduction, humans face challenges compared to other mammals. A significant number of fertilized eggs in humans do not result in live births, with up to 75% failing to develop, and around 30% of pregnancies ending within the first 10 weeks (first trimester). Recurrent…

    Hello! I wanted to see if your fertility office has a maternal age limit to transfer frozen embryos? I am 49 and have two frozen embryos that were frozen when I was 36. My current fertility clinic will not continue… — Barb J.

    Dr. Geoffrey Sher answered

    Absolutely no such age limit! Two decades ago, when women went through IVF (in vitro fertilization), they usually had their embryos put in the uterus right after the eggs were collected in the same cycle (known as "Fresh" Embryo Transfer). Freezing embryos at that time was risky, with…
