The book "Treatment Strategy for Unexplained Infertility and Recurrent Miscarriage" offers a comprehensive and informative guide to the treatment of unexplained infertility and recurrent miscarriages. It highlights specific treatment strategies that focus on uterine conditions such as chronic endometritis and disorders of endometrial decidualization. Additionally, it addresses the issue of maternal immunological rejection of an embryo as a semi-allograft. Unexplained infertility is a condition that often cannot be detected through general screening tests, and the causes frequently remain undiscovered even with assisted reproductive techniques like IVF. The book is aimed at gynecologists and provides valuable insights into the pathological conditions associated with unexplained infertility and recurrent miscarriages, facilitating better identification and explanation for affected couples.
