Cleave-stage Transfer on Day 3 Versus Day 5 Transfer When Only One Embryo Available

Transfer of Single Embryo on Day 3 or 5 When Only One Embryo Transfer

When only one embryo is available after in vitro fertilization, the option is to transfer either day 3 or day 5. There is no randomized trial compared the day 3 to day 5 for this subgroup.

Recruitment is very slow. The TSC will discuss termination next meeting with the DMC.
