No results posted yet for this study

Summary

The aim of this randomized controlled trial is to examine whether single blastocyst transfer in the first cycle after oocyte retrieval (immediate) is non-inferior to single blastocyst transfer in a subsequent cycle (postponed) in stimulated or programmed cycle frozen embryo transfer (FET). The primary outcome is live birth rate.
