    Lovenox for homogenous MTHFR 677CT

    Hello, I am currently 18 weeks pregnant following a fresh IVF transfer. Would you advise that I stay on lovenox 0.4 during the whole pregnancy since I have the following genetic mutations? - homogenous MTHFR 677CT - heterozygous PAI 4G/5G… — Kim D.

    Dr. Geoffrey Sher answered

  3. Embryos & Genetic Testing

    Is there an optimal timing of the trigger/embryo transfer on a modified natural cycle

    I went in for a scan today in anticipation of doing a modified natural cycle, it's day 10 - LH levels are rising -I've not reached ovulation yet, LH normally surges on day 14 for me. The lining was trilaminar… — Cassidy O.

    Dr. Geoffrey Sher answered

    Candidly, I am not a fan of modified natural cycle FET's. However, the time to trigger is just before the onset of the natural LH surge.; This is determined by the size (20+mm) of the dominaqnt follicle and bloopd E2. (150pg/ml+ or 300+ if there are >2 dominant…

  4. Ovarian Stimulation & OHSS

    Ovidrel only trigger

    Dr. Geoffrey Sher answered

    Empty Follicle Syndrome" is a misleading term because follicles always contain eggs. However, some eggs may have difficulties detaching and being retrieved. This is more likely to happen when multiple attempts are needed to retrieve an egg from a follicle, indicating the egg may have chromosomal abnormalities. The…

    When it comes to reproduction, humans face challenges compared to other mammals.

    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).…

    Dr. Geoffrey Sher answered

    The fact that the embryo transferred was euploid does not guarantee that it is was normal. There are genetic and metabolic factors that also can play a role. As for the low yield of "competent embryos, that likely has to do with the protocol used for ovarian stimulation.…
