Comparison of Vaginal and Intramuscular Progesterone in Vitrified-warmed Blastocyst Transfer Cycles

Summary

The aim of this study is to test the hypothesis that the pregnancy rates of women (ages 18-50 years) undergoing transfer of vitrified-warmed blastocysts (frozen at less than 41 years of age) as part of their IVF treatment are not different with respect to the administration of progesterone (Crinone® 8% vaginal gel versus intramuscular progesterone).
