Embryo-endometrial interaction.

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...

Effect of Adding Human Chorionic Gonadotropin to The Endometrial Preparation Protocol in Frozen Embryo Transfer Cycles

Biomarkers Related to Endometrial Receptivity and Implantation

Implantation is a process requiring the delicate interaction between the embryo and a receptive endometrium. This intricate interaction requires a harmonized dialogue between embryonic and maternal tissues. [Aghajanova et al., 2008; Simon et al., 2000] The three stages of implantation are: apposition, adhesion, and invasion. Apposition describes trophoblast cells adhering to the receptive endom...

P-191: A Comparison of The Effects of Transdermal Estradiol and Estradiol Valerate on Endometrial Receptivity in Frozen-Thawed Embryo Transfer Cycles: A Randomized Clinical Trial

Background: The aim of this prospective randomized clinical trial was to determine the optimal endometrial preparation protocol by comparing the clinical outcome of two methods of endometrial preparation in FET cycles, that is, oral estradiol and 17 β-estradiol transdermal patch. Materials and Methods: A total number of 90 patients were scheduled for FET. In the study group (n=45), 17-B estradi...

Effect of adding human chorionic gonadotropin to frozen thawed embryo transfer cycles with history of thin endometrium

BACKGROUND Embryo implantation process is a complex phenomenon and depends on fetal and maternal factors interaction. Endometrial thickness is needed for successful implantation. OBJECTIVE We designed this study in order to assess adding human chorionic gonadotropin (HCG) to the conventional protocol in endometrial preparation in women with thin endometrium and a history of in vitro fertiliza...

I-27: Different Regimens for Endometrial Preparationl

Freezed embryo transfer increases the cumulative pregnancy rate, reduces costs, is relatively simple to undertake and can be accomplished in a shorter time period compared to repeated Fresh cycle. There are different protocols for endometrial preparation. Although frozen embryo replacement cycles, have been used for several years, there is no agreement about the optimal way to prepare the endom...
