Clinical Trial Summary

The objective of this proof of concept clinical trial is to evaluate the impact of two different progesterone treatments for endometrial preparation (25 mg/twice-a-day, subcutaneous injection, and 200 mg/three times a day, vaginal administration) on the clinical pregnancy rate in women undergoing frozen embryo transfer (FET) at blastocyst stage.
