Egg Freezing - Cryopreservation, for Fertility Preservation

We are currently freezing eggs using the highly successful vitrification method at the Advanced Fertility Center of Chicago

We offer egg freezing for:

  • Fertility preservation for women with cancer that will soon start chemotherapy or radiation
  • Fertility preservation for women that want to store "younger" eggs for the future

When should a woman consider freezing eggs?

We also offer frozen eggs for egg donation

Cryopreservation of oocytes - what is egg freezing?

Human egg (oocyte) freezing, or cryopreservation, has been done since the 1980s. However, its use has become much more widespread since about 2007.

Starting in about 2007, egg freezing moved more into the "mainstream" of what is being offered at fertility centers in the US. It is being marketed and utilized as a method for "preserving fertility" for women that are concerned that they are aging - but not ready to have children yet.

  • Advancing female age is a major factor causing infertility

In October 2012 the Practice Committee of the American Society for Reproductive Medicine (ASRM) issued a report saying that in young patients egg freezing techniques have shown pregnancy rates and births of healthy babies that are comparable to IVF cycles using fresh eggs. They therefore removed the "experimental" designation for egg freezing at that time.

Since then, many women have chosen to freeze their eggs in an attempt to preserve their fertility for the future.

Potential reasons for freezing eggs

Chemotherapy and fertility

Sometimes women of reproductive age are diagnosed with breast cancer or other cancers that require treatment with toxic chemotherapy or radiation. Many of the powerful drugs used to kill cancer cells are also toxic to eggs. Likewise for radiation to the pelvic area.

Therefore, chemotherapy or radiation treatments will often result in premature menopause, or will severely reduce the woman's ovarian reserve (egg supply for the future).

Egg freezing (also called oocyte cryopreservation) to attempt fertility preservation in cancer patients should usually be discussed if they want children in the future. In such a scenario, the woman would have some of her eggs frozen prior to starting cancer treatment. She could use the frozen eggs in the future after being cured of cancer, if needed.

Women delaying starting a family for personal reasons

The other, and much larger group of women that will use egg freezing for fertility preservation are women that are freezing eggs because they are not ready to have children yet. This has been referred to as "social egg freezing" in the past.

These women choose to freeze some eggs at a "younger" age (often in the late 20's or early to mid 30's) for use later when they are ready to have children. They are hoping to "freeze the biological clock" for those eggs.

Some of these women would like to start a family soon but want to wait until they are in a stable long-term relationship. Otherwise, women often want to delay childbearing because they are busy pursuing education, or focusing on their career, or they are just are not ready to have kids yet.

Laboratory techniques and egg freezing methods

Vitrification (ultra-rapid freezing) of eggs is a more successful technique as compared to the older technique of "slow freezing". Many US clinics (including ours) have been utilizing vitrification to freeze eggs and are seeing excellent results.

At our clinic we have extensive experience with both freezing and thawing eggs as well as fertilizing the thawed eggs and transferring the embryos. We have years of experience through our frozen donor egg program with high pregnancy and live birth rates resulting after transfer of embryos from the frozen eggs.

Many fertility clinics can freeze eggs but far fewer have much experience with freezing and then thawing and fertilizing eggs and transferring the embryos.

I am so grateful for Advanced Fertility Center. I just had my son Leland. I want to thank Dr. Catenacci and all of the nurses that helped us. Especially Ashley in the Crystal Lake office. You made this process easier by being supportive and positive. Thank you very much!


Dr. Sherban and his staff are the most amazing, compassionate, and supportive people. After almost 5 years of trying to conceive, going through numerous tests and meeting with another clinic closer to home, who told me my chances even with IVF were still very low, a good friend recommended advanced fertility center of Chicago. Best decision we ever made! We now have 2 amazing children who are now 5 and 3 years old! I cannot stress enough how amazing this staff is, they make you feel like family!


Our experience was amazing with Dr. Cantanucci and all of the nurses (especially Ashley). After ttc for 4 years and at 41 years of age, we became pregnant after 1 round of IVF, and had our beautiful boy this past October. Can't thank them enough!


2/7/15 our son was born all thanks to the assistance of Dr. Sherbahn and his staff. Everyone was so helpful and here for all our questions, worries, etc. They want this for you just as much as you want this for you! Handled with pure professionalism and care from the very start! Thank you advanced fertility!
