Decreasing serum estradiol level on day of progesterone start in programmed frozen embryo transfer cycles and the pregnancy outcomes.

High serum estradiol levels may reduce the success of conception and live birth in both in vitro fertilization and frozen embryo transfer (FET). This retrospective study sought to determine whether an association exists between decreasing the serum estradiol level and the clinical outcome following programmed FET cycles. The analysis retrieved the data of patients who underwent programmed FET cycles at the Center of Reproductive Medicine of Weifang People's Hospital from January 2022 to March 2023.
