Comparison of Standard versus Personalised Luteal Phase Support in patients undergoing frozen-thawed embryo transfer cycles: an open labelled randomised controlled trial

The primary objective of our study is to compare the clinical pregnancy rates between women receiving personalised serial progesterone-guided rescue luteal phase support and those receiving standard luteal phase support during frozen-thawed embryo transfer cycles. The secondary objectives include 1. comparison of other pregnancy outcomes, including biochemical pregnancy rates, miscarriage rates, and ongoing pregnancy rates between women receiving personalised serial progesterone guided rescue luteal phase support and those receiving standard luteal phase support during frozen-thawed embryo transfer cycles 2. To study the trend of serum progesterone level at different time points- day of embryo transfer, day 7 of ET, day of pregnancy test (day 14 of embryo transfer), at 6 weeks of gestation in both the groups across various protocols of Frozen thawed embryo transfer cycles.
