The Reproductive Medicine Center offers early and late forms of embryo transfer. Specifically, we have the ability to transfer embryos on the second, third, fourth, fifth and sixth day of growth. We discuss with each patient the decision on which day to transfer the embryos. The center has had equal success in all embryo transfers. We specifically reserve our Day 5 and Day 6 embryo transfers for couples undergoing preimplantation genetic diagnosis. We also use Day 5 and Day 6 embryo transfers for couples who have a large number of high-quality embryos available for selection. There are specific circumstances in which we offer Day 5 or Day 6 culture. Most couples have very high success with Day 3 embryo transfer, as well. We treat patients as individuals and try to determine the best means and type of embryo transfer for them.
