Modified Luteal Support for Frozen-Thawed Embryo Transfer - A Prospective Study

Summary

This study evaluates the outcomes of frozen-thawed embryo transfer (FET) success rate with modified luteal support - addition of a single injection of HCG and GnRH-agonist, on day of ET and 4 days later, respectively vs. traditional luteal support with vaginal progesterone only in ovulating women.
