I-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 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 کاملImplantation failure: molecular mechanisms and clinical treatment.
BACKGROUND Implantation is a complex initial step in the establishment of a successful pregnancy. Although embryo quality is an important determinant of implantation, temporally coordinated differentiation of endometrial cells to attain uterine receptivity and a synchronized dialog between maternal and embryonic tissues are crucial. The exact mechanism of implantation failure is still poorly un...
متن کاملendometrial receptivity to implantation in humans: biochemical and molecular aspects
the success rate of several advanced basic and clinical techniques in the field of mammalian biotechnology, including cloning, pre-implantation genetic diagnosis, and assisted reproductive techniques (art) depends mainly on the success rate of pregnancy following in vitro fertilization-embryo transfer (ivfet). the techniques used in art have advanced considerably since the first in vitro fertil...
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...
