Natural Cycle Versus Hormone Replaced Cycle
Sponsor: Women's Hospital School Of Medicine Zhejiang University
Summary
Recent sutdies indicate that the existence of corpus lutein in the ovary is a key point to prevent preeclampsia, and patients undergoing FET with hormone replaced cycle have no corpus lutein and the absence of corpus lutein significantly increases the risk of preeclampsia in these patients. We aim to conduct a single center randomized controlled non-inferiority trial to compare the live birth rate and gestational hypertention disease rate between the natural cycle and the hormone replaced cycle in women undergoing FET.
