Egg & Embryo Freezing:


What is Cryopreservation?

Cryopreservation is a technologically advanced method to preserve and save harvested eggs or embryos for future use.

Egg freezing might be an option if you're not ready to become pregnant now but want to try to make sure you can get pregnant later.

Embryo freezing (fertilized oocyte) freezes and stores fertilized eggs for later use. It’s often used with fertility treatments that create embryos, such as in vitro fertilization (IVF). It also can help people preserve fertility and get pregnant in the future.

How successful is this procedure?

The success rates for an egg or embryo surviving the freezing and thawing process are higher using the newer vitrification technology and are closer to the success rates of using fresh embryos for implementation. The embryology team at PMH Fertility Center has extensive experience with the technique of fertilizing previously vitrified eggs.

They have achieved egg survival rates of approximately 80%, fertilization rates of over 80%, and pregnancy rates above 50%.
