Impact of different endometrial preparation protocols on pregnancy outcomes in patients at high risk for ovarian hyperstimulation syndrome: a propensity score matched retrospective cohort study.

ABSTRACT:

Background

Few studies have analyzed the endometrial preparation protocols for frozen-thawed embryo transfer (FET) in patients at high risk of ovarian hyperstimulation syndrome (OHSS). This study aimed to investigate the optimal protocol for endometrial preparation in FET cycles for patients at high risk of OHSS.

Methods

This study included women who underwent assisted reproductive technology treatment between January 2021 and December 2022 at the Center for Assisted Reproductive Technology of Northwest Women's and Children's Hospital, China.Patients were categorized into three groups based on their endometrial preparation protocols: hormone replacement therapy (HRT), natural cycle (NC), and ovarian stimulation (OS).
