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

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...

Frozen-thawed embryo transfer cycles

In order to reduce the chance of multiple pregnancy during in-vitro fertilisation (IVF)– embryo transfer treatment, there is an increasing trend towards transferring a lower number of embryos. Surplus good-quality embryos are then transferred in frozen-thawed embryo transfer (FET) cycles. The first pregnancy after FET was reported in 1983.1 It has been estimated that in IVF programmes in which ...

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

BACKGROUND Human chorionic gonadotropin (HCG), one of the initial embryonic signals, is probably a major regulator of the embryo-endometrial relationship. This study aims to assess the advantage of HCG supplementation during the secretory phase of hormonally prepared cycles for the transfer of cryopreserved-thawed embryos. MATERIALS AND METHODS This study was a randomized clinical trial. Infe...
