Immediate Versus Postponed Single Blastocyst Transfer in Programmed or Stimulated Cycle Frozen Embryo Transfer
Sponsor: Rigshospitalet, Denmark
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.
