Egg Freezing

Many people would like to have a child, but there are other goals they want to accomplish before becoming parents.

Thanks to egg freezing, Drs. Nurit Winkler and Marc Kalan can help preserve a woman's fertility so she can have a family when she is ready.

Our double board-certified doctors provide oocyte freezing at our Encino and Bakersfield, CA, offices...

What Is Egg Freezing?

Egg freezing, also known as oocyte cryopreservation, allows women to preserve their reproductive potential. The process has quickly 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. Our fertility clinic serving Greater Los Angeles is glad to help you explore this option.

Drs. Kalan and Winkler

Helping Los Angeles-Area Patients Plan and Grow Their Families

"[Dr Kalan] was very sweet, responsive, knowledgeable, and caring about his work and his patients. If there was a problem he wanted to be thorough and would talk to you about any additional testing he recommended to be done. He spoke in ways that helped me understand things." Melie Sin

The Egg Freezing Process

It typically takes about two menstrual cycles to complete the egg freezing process at our practice serving Encino, Bakersfield, and Greater Los Angeles.
It is typically recommended that patients freeze about 10-20 eggs per cycle. Because not every fertilized egg will result in an embryo, this helps you have a better chance of pregnancy during the IVF process.

Your doctor will prescribe medications like birth control and hormone injections. This will help with timing your cycle for retrieval and halt the body's natural production of certain hormones.

Ovarian Stimulation

After a few weeks, you will begin taking medications to stimulate egg production. The body naturally only produces one egg during a cycle. This will stimulate your body to produce multiple mature eggs during a single cycle.


Your doctor will monitor you throughout the process to ensure proper egg development. Monitoring may include vaginal ultrasounds so your doctor can see the follicle development.

Egg Retrieval

After using fertility drugs to stimulate development, mature eggs are harvested directly from the ovaries. Multiple eggs are retrieved during this process to increase your chances of a healthy embryo later. During the egg retrieval process, patients are sedated in order to minimize discomfort.


The harvested ova are flash-frozen and kept well below freezing temperatures to prevent the breakdown of cells. Once you freeze your eggs, they can remain viable for many years.

IVF Cycle

When the patient is ready to have children, the frozen eggs are thawed and used in an IVF cycle. The frozen eggs can be fertilized by sperm from a partner or a donor to create an embryo. 

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 in Bakersfield and Encino.

Is There an Ideal Age
for Freezing Eggs?


Many women consider freezing eggs before age 35 to ensure peak viability. We encourage you to read our egg freezing FAQs or contact our team of fertility specialists if you have more questions regarding this or other infertility treatments.

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.
