Egg Freezing

Our cryopreservation (sperm, egg, embryo, and ovarian tissue storage) program is one of the best in the world. We have a 55% pregnancy rate per cycle with frozen embryos, which is no different than for fresh, or unfrozen, embryos. Our frozen embryo survival is almost 99%. Therefore, if you have "extra" viable embryos resulting from your IVF procedure, you can feel comfortable allowing us to freeze them.

We can now also offer egg freezing for women who wish to delay childbearing, and who want to preserve their fertility for the future. Although the freezing of embryos has been quite reliable, the freezing of eggs was for a long time only experimental, and, until recently, not very successful. However, the Infertility Center of St. Louis has begun a partnership with the Kato Ladies Clinic in Tokyo to bring an exciting new technique, egg vitrification [see technical video], to the United States. With this method, we can 'flash-freeze' unfertilized eggs with a remarkable effectiveness, and then thaw them at any later date for reimplantation. We can also offer ovarian tissue freezing for women who do not want to undergo IVF in the future but who just want to conceive naturally.
