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

    Dr. Geoffrey Sher answered

    In my opinion this is almost certainly an implantation dysfunction. Bear in mind that in 30% of cases, endometriosis is associated with an immunologic implantation dysfunction. Implantation dysfunction is often overlooked as a significant reason for IVF failure. This is especially true when IVF failure is unexplained, or…
