Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The association between serum progesterone (P) levels, measured on the day of ovulation trigger, and the outcome of in vitro fertilization cycles, has been one of the major controversies in the field of ovarian stimulation endocrinology.

This is a single-center retrospective cohort study. Study duration period is from January 2012 to December 2016.

All fresh embryo transfer (ET) both at cleavage stage and blastocyst stage, performed in Humanitas Fertility Center during the study period, were included.
