Egg Freezing

Many people would like to have a child, but there are circumstances when delaying pregnancy is best.

Thanks to egg freezing, Drs. Nurit Winkler and Marc Kalan can help preserve a woman's fertility to delay starting a family.

What Is Egg Freezing?

Egg freezing, also known as oocyte cryopreservation, is a groundbreaking method for women to preserve their reproductive potential. The process quickly has become the most popular form of fertility preservation in the United States.

During the process, viable eggs are harvested from the ovaries and frozen at sub-zero temperatures. When the patient is ready to have a child, the preserved ovum is thawed and used in an in vitro fertilization (IVF) cycle.

Fresh vs. Frozen Eggs Success and Live Birth Rates

Comparing Numbers

Since initially attempted in the 1980s, the methods and success rates of egg freezing have improved dramatically. That said, studies have found that the use of unfrozen eggs still yields higher live birth rates than frozen eggs. According to the Centers for Disease Control and Prevention (CDC), fresh ova have a live birth rate of 57.1 percent, while frozen ova have a live birth rate of 44.2 percent.

Techniques Continue to Improve

As studies continue to confirm the efficacy of egg freezing, the American Society of Reproductive Medicine (ASRM) has declared that oocyte cryopreservation is no longer an experimental process. We can discuss if fresh or frozen eggs are better for you during a consultation at our offices serving the Los Angeles and Encino area.

I came here and let me tell you dr. winkler is the best. I had infertility issues for years. I thought I wasn’t going to be able to have kids and thanks to her I conceived within months with injectable medication and IUI. I am very happy now I’m 17 weeks pregnant. The staff was also nice very understanding. I recommend this place if you’re trying to conceive, give them a try

Dr. Kalan is the best doctor we have ever met. He’s a professional, ability, knowledgeable, friendly, patience and responsible doctor. We are so lucky to find him. We went and worked with serval IVF clinics before we found Dr. Kalan. I remembered one IVF that we only met that doctor first time. Then he disappeared for our next visits. The nurse, Ivanna and Joana are very nice, friendly and patient. They always replied my email very quickly. My husband and I very appreciate Dr. Kalan and his nurses give us help and support. We have very happy IVF journey with Dr. Kalan's clinic.
