What is egg (oocyte) cryopreservation?

Freezing a woman’s eggs is also a new and experimental procedure. Just like embryo cryopreservation, you’ll take medications that make you produce many eggs. This takes two to three weeks. But unlike embryo cryopreservation, the eggs are not fertilized before they are frozen. Eggs that survive the freeze-thaw process will then be fertilized in the laboratory with the partner’s or donor sperm. Embryos that develop will be placed in your uterus. Unfortunately, human eggs do not survive freezing very well and this procedure has not been very successful. Doctors are still in the process of figuring out if more mature (developed) eggs freeze better than less developed (immature) eggs. The aspiration (gentle suction) of immature eggs without using stimulation medications has also been performed and some pregnancies did occur.
