Repeated Implantation Failure

چکیده
Successful embryo implantation is a process which requires both a synchronous development and interaction between hatched blastocyst and endometrium. The process of implantation as a scheme is presented in Pic. 1, where the diagram shows a preimplantation stage of embryo and some important factors thought to be necessary for uterine receptivity: COX-2 (cyclooxygenase-2), EGF (epidermal growth factor) and LIF (leukemia inhibiting factor). From the clinical point of view, implantation is considered to be successful when gestational sac is diagnosed by ultrasound.

Background: HLA-G, as a tolerogenic molecule, expressed in cytotrophoblast cells and playing an important role in the suppression of the immune response in maternal decidua. Today Interaction of the extracellular domains of HLA-G protein with cell receptors of immune system, including CD8, LILRB1, LILRB2 and killer cell immunoglobulin-like receptor KIR2DL4, was well known. Materials and Methods...
متن کاملCytokine Profile in the Endometrium of Normal Fertile and Women with Repeated Implantation Failure
Background: Repeated Implantation Failure (RIF) is one of the most intricate obstacles in assisted reproduction. The cytokine and chemokine composition of uterine cavity seem to play important roles in the implantation process. Objective: To compare the cytokine profile in the endometrium of normal fertile women and those with repeated implantation failure. Methods: After enzymatic digestion of...

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 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-23: The Role of Hysteroscopy in Patients with Repeated IVF Failure
The success of reproduction, although gradually increasing over the years, many couples also had been left frustrated following repeated failed attempts. Implantation of the embryo, can only take place in a receptive uterus and inadequate uterine receptivity is responsible for approximately two-thirds of implantation failures. Endometrial receptivity can be reduced by morphological and/or molec...

Background: In spite of the great deal of research in assisted reproductive techniques, more than 80% of transferred embryos by IVF/ICSI methods fail to be implanted. The causes for repeated implantation failures (RIF) may be reduced endometrial receptivity or other various uterine pathologies, such as thin endometrium, altered expression of adhesive molecules or immunological factors; whereas ...
