    • Geoffrey Sher says:

      When confronted with repeated “unexplained” IVF failures where morphologically good embryos were transferred, the question arises as to whether the problem is due to inherent egg/embryo “incompetence” (which usually equates with an irregular chromosomal configuration [aneuploidy]) or whether it is due to an implantation dysfunction. The younger the woman and the higher the quality of available embryos (preferably blastocysts), the less likely it is that the fault lies with embryo “incompetence” and the greater is the likelihood that it is due to underlying implantation dysfunction.
      The most common causes of implantation dysfunction are:
      a) A “thin uterine lining”
      b) A uterus with surface lesions in the cavity (polyps, fibroids, scar tissue)
      c) Immunologic implantation dysfunction (IID)
      Implantation dysfunction (anatomical or immunologic) is a common cause of repeated “unexplained” IVF failure with good embryos. This is especially the case in young ovulating women who have normal ovarian reserve and have fertile partners. Failure to identify, typify, and address such issues is, in my opinion, an unfortunate and relatively common cause of repeated IVF failure in such women.

      Important Announcement:

      Dr Al Peters (Medical Director at SIRM-New Jersey), and I ,recently established the “SIRM Reproductive Immunology Forum(SRIF) which will provide a venue where you can address and hopefully find solutions to problems relating to Immunologic Implantation dysfunction (IID) that often manifest with “Unexplained” infertility, IVF Failure and Recurrent Pregnancy Loss (RPL..

      To this end we established , a dedicated website where you can:
      • Register with SIRF
      • Request and receive (free of charge) a PDF copy of our book: “Unexplained” Infertility and Miscarriage : The Immunologic Link”
      • Be kept abreast of what is current in the IID arena
      • Post questions for Dr Peters and I to respond to and,
      • Interact with other patients on a separate discussion board dedicated to this.

      We look forward to hearing from you!
