Implantation failure in assisted reproduction technology and a critical approach to treatment.

摘要: In this article, we review the literature and our personal experience regarding many factors that appear to influence implantation rate. Oocyte quality, as determined by patient age aneuploidies, probably plays a major role in RIF. However, panoply of other have been brought under investigation, quite often with contradictory results additional intriguing questions be studied. Infections vagina, cervix, endometrium, mucus aspiration washing cervix on transfer, catheter guidance for correct transfer potion embryos, effect mock hysteroscopy its timing before procedures are analyzed both opinions data from experience. Many these interlaced apparently simple issue trauma, infections immune modulation hatching implantation, biological continuum can easily identified. The impact abnormalities system homeostasis is also covered brief overview reported works These latter areas constitute common background all external that, however, skilled must equip themselves improving success.
