Natural Cycle or Stimulated Cycle Versus Hormone Replaced Cycle for Pre-eclampsia Rate
March 14, 2020 updated by: Women's Hospital School Of Medicine Zhejiang University
The Live Birth Rate in Natural Cycle or Stimulated Cycle Versus Hormone Replaced Cycle in Patients Undergoing Frozen-thawed Embryo Transfer
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 trial study to compare the preeclampsia rate between the natural cycle and the hormone replaced cycle in patients undergoing FET.
