The process for using your eggs is the same as in an in vitro fertilization (IVF) cycle. First, your eggs are thawed in a highly controlled lab environment. One sperm is injected into each surviving egg and incubated overnight. Some of the embryos will continue to grow and divide, creating blastocysts, (embryos that are ready for transfer into your uterus). The embryo transfer is a quick and easy office procedure. The estimated livebirth rate per thawed egg is 5-12% in women under 35 years of age.
