Immediate Versus Postponed Single Blastocyst Transfer in mNC-FET
Sponsor: Rigshospitalet, Denmark
Summary
The purpose of this randomized controlled trial is to investigate if immediate single blastocyst transfer (in the first menstrual cycle following oocyte retrieval) is non-inferior to standard postponed single blastocyst transfer (in the second or subsequent menstrual cycle following oocyte retrieval) in modified natural cycle frozen-thawed embryo transfer (mNC-FET) in terms of live birth rate.
