What is the Impact of Frozen Embryo Transfer Protocol, on Endometrial Compaction

This study aims to evaluate endometrial thickness on the day of the frozen embryo transfer, compared to endometrial thickness on the last day of assessment of the endometrium before exposure to progesterone in respect to the protocols used for endometrial preparation

247 FET cycles were included in the study. Records of all patients and their cryopreservation embryos were analyzed. Data collection included baseline parameters of age, BMI (kg/m2), type of infertility, parity, lifestyles, and cause of infertility, as well as treatment parameters, including number of embryos transferred, embryo quality and pregnancy outcomes.

To reflect the broad range of patients typically encountered in clinical practice, no inclusion/exclusion criteria were applied regarding baseline characteristics.
