Sponsor's own description

Fresh embryo transfer is a routine procedure in vitro fertilization (IVF) treatment. Since the first live birth after an IVF-FET (frozen embryo transfer), recent years have seen a dramatic rise in the number of FET cycles. Three endometrial preparation protocols for frozen-thawed embryo transfer, including artificial, natural, modified natural protocol, have been studied and applied to maximize treatment outcomes. However, those methods are being applied empirically as their efficacy and safety are yet to be determined. The objective of this study is to compare the effectiveness and safety of those protocols.
