    Dental bone graft before FET

    Hi Dr.Sher, Thank you for taking the time to answer my question. A month prior to my FET I had dental bone graft placed. I took a full course of antibiotics and the healing was uneventful. Following month, my FET… — Ramya S.

    Dr. Geoffrey Sher answered

    The dental surgery and antibiotics would not have affected outcome. ADDITIONAL INFORMATION: I am attaching online links to two E-books which I recently co-authored with my partner at SFS-NY (Drew Tortoriello MD)....... for your reading pleasure: 1.From In Vitro Fertilization to Family: A Journey with Sher Fertility Solutions…

    Fever after FET

    I had my FET 3 days ago of two embryos and 36 hours later experienced cold/flu symptoms (sore throat, cough, headache) which was accompanied by a rising temperature, which went up to 100.6. Can this negatively impact implantation? I am… — Victoria R.

    Dr. Geoffrey Sher answered

    Let me assure you that this is not due to your body reacting to the embryo(s). It is likely unrelated to the FET. I suggest you see your doctor and be evaluated to make sure it is not Covid. In the interim, try to keep your temperature down…

    3 failed pgs donor fet transfers

    Hi Dr. Sher, I have a child conceived naturally at 39 and then two early miscarriages also natural conception (first loss at 6 weeks and second loss at 7 weeks prior to heartbeat being detected) at age 42 and age… — Eliana B.

    Dr. Geoffrey Sher answered

    This is highly likely to at least in part, be due to a secondary implantation dysfunction (see below). While not definitive, I suspect an immunologic implantation dysfunction (IID). The fact that you have had a child already means that it if an IID exists, it is possibly alloimmune…

    FET Protocol Opinion

    Hi, I just wanted a second opinion on what my FET protocol looks like given my personal situation. I was diagnosed with endometriosis via laparoscopy in 2018. I did a total of 6 IUIs in 2021-2022 with my 4th one… — Taylor A.

    Dr. Geoffrey Sher answered

    This is an inordinate drop off from egg to "competent" embryo. In my opinion, , in spite of your borderline AMH (1.48ng/ml) which would suggest otherwise, you are a high responder to fertility drugs. The most likely explanation for your poor egg to "competent" embryo conversion has to…

    What causes embryos to arrest during development?

    I recently completed my 2nd egg retrieval at age 36 and had very different results. I have PCOS (high AMH =15 and many follicles, regular periods, thin/normal BMI ) and respond well to meds. We used 75 Menopur, 100 Gonal… — Maya S.

    Dr. Geoffrey Sher answered

    It could be an inherent underlying egg defect. However, more commonly it has to do with the selection of an optimal protocol for ovarian stimulation, the type of "trigger used" and the implementation of said protocol. The importance of the IVF stimulation protocol on egg/embryo quality cannot be…

    32, 3 failed IUIs, 1 failed IVF transfer

    Hi, I’m 32 years old and was diagnosed with mild endo which was removed last year. I’ve also had a few polyps, fibroids and cysts removed in the past 2 years. I had 3 failed IUIs and recently my first… — Miranda B.

    Dr. Geoffrey Sher answered

    I suggest we talk. Please consider calling Patti Converse (my assistant) at 702-533-2691 and set up an online consultation with me to discuss. When women with infertility due to endometriosis seek treatment, they are all too often advised to first try ovarian stimulation (ovulation Induction) with intrauterine insemination…

    steroids for raised TH1/TH2 assay

    I had my first child with no difficulty. followed by 3 losses due to chromosomal issues then went to IVF and had 1 successful birth! We have been trying for the last 4 years and it has resulted in 2… — Tasnem A.

    Dr. Geoffrey Sher answered

    Your raised TH1: TH2 suggests activated uterine natural killer cells. In your case, having had a child already, this suggests that it is alloimmune rather than autoimmune, immunologic implantation dysfunction (IID). This would require a different approach to treatment. First, however you need to establish a diagnosis. We…

    Thin Endometrium

    Hello Dr., I am currently 36 with unexplained infertility. We sought help in 2019 and ended up with a successful IVF cycle, 7 PGS -tested normal embryos (1 day 5 and 6 day 6). We transferred our day 5 embryo… — Natasha B.

    Permutation Fragile X

    I have have had 2 pregnancies, 1 resulted in miscarriage and the other resulted in mono-di girls. I am a permutation fragile x carrier and they have the gene as well. Myself and my husband would like to go through… — Randi T.

    Dr. Geoffrey Sher answered

    The answer to both questions is yes! Fragile X syndrome occurs in individuals who carry the gene, FMR1 on an X-chromosome. This condition is inherited as a dominant X-linked disorder. With a dominant disorder, the condition results when there is only one copy of the altered gene in…

    Euploid embryo transfer after giving birth

    Dear Dr Sher, I have just given birth to baby son ( September 3d). The pregnancy was miracle due to natural conception in December last year. I delivered naturally (not C-section) at 39 weeks 4 days so at full term.… — Sayora G.

    Dr. Geoffrey Sher answered

    I would use both the euploid blastocysts. My suggestion is that once you have stopped breast feeding and are menstruating regularly you proceed to FET. Good luck!

    Hi, I'm 40 years old, 3 failed IUI during the last year and consulting for IVF. I'm looking for a clinic that allows me 2 embryo transfer at once for a chance of twins. is this possible at your clinic? — Nagibe C.

    Dr. Geoffrey Sher answered

    I would absolutely consider this favorably! I suggest you call my assistant, Patti Converse at 702-533-2591 and set up an online consultation with me to discuss. Geoff Sher

    Reproductive potential of euploid in women >40

    Hi Dr Sher, I hope this message finds you very well! I'm turning 44 soon and have finished the embryo banking process (2 euploid embryos + 7 LLM embryos). Clearly I'm unlikely to retrieve any more euploid embryos at my… — Cassidy O.

    Dr. Geoffrey Sher answered

    Thank you for your communication. Although age primarily affects IVF outcome through impacting the risk of aneuploidy, it also presumably has an effect via other factors (metabolomic and epigenewtic) although these are far less relevant. In my opinion, you would be well served to evaluation for embryo implantation…

    Chromosomal Abnormalities

    High doses of drugs used to stimulate the ovaries of older women undergoing fertility treatment may be causing chromosomal abnormalities in their eggs? — Tina M.

    repeated implantation failed

    Dear Dr, Embryo Solution recommended me to contact you to get your point of view on my fertility problem. With my husband we have a severe male infertility problem and in 2017 we did a fertility treatment when we lived… — Sofia G.

    Dr. Geoffrey Sher answered

    The commonest cause of your type of issue relates to egg/embryo "competency". AND here, the protocol used for ovarian stimulation is pivotal. The importance of the IVF stimulation protocol on egg/embryo quality cannot be overstated. This factor seems often to be overlooked or discounted by t IVF practitioners…
