I-16: The Immunological Aspect of Implantation Failure
The success of reproduction, although gradually increasing over the years, many couples also had been left frustrated following repeated failed attempts. Clinicians who treated unsuccessful couples often face a challenge. The probable causes of repeated IVF failures classified as: reduced endometrial receptivity, embryonic defects or multifactorial causes. Intrauterine and endometrial integrity...
متن کاملPolymorphism of Genes and Implantation Failure
Implantation failure is the most frequent cause of pregnancy loss in couples who try to conceive, either in a natural way or using assisted reproductive techniques (ART). Identify the precise mechanisms of implantation failure can lead to identify couples at risk and also providing appropriate therapeutic options to affected couples. Despite the high prevalence of this disorder, a few causing f...
متن کاملI-40: Implantation Failure
Background: The process of implantation involves the interaction of the human embryo and the uterine epithelium. Failure of implantation is a major reason for infertility in women and the inability to achieve endometrial receptivity is responsible for much of the failure of reproductive technologies. Management of repeated implantation failure despite transfer of good-quality embryos still rema...
متن کاملI-24: Recurrent Implantation Failure
Recurrent implantation failure (RIF) has many definitions, but usually authors consider RIF, the failure to achieve a pregnancy fallowing 2-6 IVF cycles in which more than 10 high grade embryos were transferred to the uterus. There are a lot of causes for RIF but two main causes of that are related to embryo and endometrium. Chromosomal abnormalities, zona hardening and problems in culture medi...
متن کاملImplantation: can immunological parameters of implantation failure be of interest for pre-eclampsia?
We restate briefly why we consider that the Th1/Th2 paradigm, as useful as it has been, is now no longer adequate and is obsolete. We take as an example the role of IL-18, abortifacient at high doses but cardinal for the control of natural killer (NK) cell effects on spiral artery remodelling in mice, and likely also in humans. We then describe briefly our recent studies on cytokine defects and...
