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...

Identify the precise mechanisms of implantation failure can lead to identify couples at risk and also providing appropriate therapeutic options to affected couples.

Repeated implantation failure (RIF), defined as three or more failed IVF attempts or failure of IVF after cumula- Abstracts of the 5...
متن کاملI-24: The Role of Interleukins, Integrins and Other Proteins in Recurrent Implantation Failure
Embryo implantation represents the most critical step of the reproductive process in many species. Inadequate uterine receptivity is responsible for approximately two-thirds of implantation failures. The cell adhesion molecule (CAM) such as integrins, cadherins, selectins and immunoglobulins intervene to ensure adhesiveness between the embryo and the endometrium. Some recent studies indicate th...
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...
