Research progress on endometrial preparation for frozen-thawed embryo transfer cycles in patients with endometriosis
Endometriosis(EMS)is a common disease afflicting females of reproductive age and a common indication of human assisted reproductive technology.With the development of technology of vitrification,frozen-thawed embryo transfer(FET)has become an essential component of in vitro fertilization.The factors that affect the success of FET include embryo quality,endometrial receptivity,and synchronization between embry and endometrium.The preparation of the endometrium is a key step in embryo implantation and live birth.EMS is considered as an important cause affecting endometrial receptivity.At present,there are few studies and controversies on the FET endometrial preparation plan for EMS patients.This article reviews the pregnancy outcomes and maternal infant complications of FET endometrial preparation in EMS patients by analyzing existing literature,providing reference for clinical decision-making.
