    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…

    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…

    I recently got an embryo report back from coopergenomics and it's euploid, but my PGT-M result came back with maternal chromosome contamination. Do you think this can effect success rates? — Julie G.

    You need to discuss this with your personal RE. Good luck! Geoff Sher

    Day 6 and Day 7 euploid embryos

    I'm 36 and doing IVF with PGT-A and PGT-M to avoid passing on a genetic condition I'm a carrier for. I don't have any identified fertility issues and have had a viable natural pregnancy before at age 34. I've had… — Charlotte D.

    Dr. Geoffrey Sher answered

    Frankly, you and I should have an in depth discussion to address these issues. I do not believe there is merit in transferring day 7 blastocysts whether or not they are euploid. The chance of pregnancy is dismal. There could be embryo issues relating to a possible deficiency…

    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?.…

    There is really a great deal to talk about here. I strongly urge you to call my assistant Patti at 702-533-2691 and set up an online consultation with me. Given your history of 3 losses I think that aside from an egg/embryo quality issue you could, in addition,…

    Dr. Geoffrey Sher answered

    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 (IUI) ………as if to say that this would be just as likely to result in a baby as would in vitro fertilization (IVF).…

    FET protocol
