Brief Summary
The purpose of this small-scale pilot study (10 patients) is to test the study protocol for an RCT comparing IVF outcomes between day 3 and day 5 embryo transfer in patients with five or fewer embryos in a fresh embryo transfer in vitro fertilization (IVF) cycle. Information derived from this RCT would allow us to maximize the chances of success for these patients undergoing IVF.
