Embryo transfers (ET) on day 2 or day 3 following fertilization have been the standard of practice since the initial days of human in vitro fertilization (IVF). Recent advances in culture media, as well as embryo culture techniques, have prompted in a shift in strategy to day 5 blastocyst transfers following IVF. However blastocyst transfers, although resulting in slightly better pregnancy rate, are known to be associated with certain disadvantages, such as higher costs, higher cycle cancellation rates, and in vitro damage to embryos. Thus we reviewed our results with day 2 and day 3 ETs to see whether outcomes were adequate to justify a return to day 3 embryo transfer policy. Our data shows a 46% clinical pregnancy rate and 1.9% incidence of multiple pregnancy rate with cleavage transfers. Thus in our setting with a lot of poor resource patients, we feel day 2 or 3 transfer provides a good strategy for IVF cycles.
