Once eggs and embryos are frozen, or cryopreserved, they can remain in that state for years, or even decades, according to Dr. Jim Toner, a fertility doctor with Atlanta Center for Reproductive Medicine.
Egg freezing is in the news since the American Society of Reproductive Medicine (ASRM) just announced that egg freezing is no longer considered experimental. This is the culmination of years of scientific struggle with the difficult technical aspects of freezing eggs. While freezing sperm and embryos has been routine for many years, freezing eggs has remained a mystery until very recently.
Frozen egg banks are a new option in egg donation, Dr. Joel Batzofin, New York Fertility Services</a> explains. Egg are donated and frozen without a recipient identified. When a recipient chooses that donor, she uses the thawed eggs in an IVF cycle.
