    Dr. Geoffrey Sher answered

    At 42 years of age and especially if you are experiencing diminishing ovarian reserve, a flare protocol (in my opinion) is less than ideal. I suggest you call my assistant, Patti at 702-533-2691 and set up an online consultation with me. Geoff Sher EGG/ EMBRYO QUALITY IN IVF…

    Dr. Geoffrey Sher answered

    Each follicle should contribute 150-200pg/ml to the E2 level. Your dropping E2 is concerning and suggests premature luteinization. I think when this cycle is over we should talk. The protocol used for ovarian stimulation and its implementation are both pivotal. Call my assistant, Patti at 702-533-2691 and set…

    Dr. Geoffrey Sher answered

    Implantation dysfunction is often overlooked as a significant reason for IVF failure. This is especially true when IVF failure is unexplained, or when there are recurring pregnancy losses or underlying issues with the uterus, such as endo-uterine surface lesions, thin uterine lining (endometrium), or immunological factors. IVF success…
