Oocyte Cryopreservation

The single most important factor affecting fertility in women is age. In the 21st century women are focusing on education, travel, and career in turn postponing starting a family. In addition, many single women opt to freeze their eggs before they meet their life partner. Eden Centers for Advanced Fertility (Eden) understands priorities change and we would be happy to provide you with options to preserve your fertility.

What is egg freezing?

An egg freezing cycle (mature oocyte cryopreservation) is the process where eggs are retrieved from your ovaries, frozen and stored for your future use. This process allows you to pause your biological clock, providing you the opportunity to use your “younger” eggs that have been preserved.  To complete an egg freezing cycle you undergo controlled ovarian stimulation with fertility drugs, and an egg retrieval. Once the eggs are retrieved they are cryopreserved and stored in our highly advanced IVF laboratory.

Who should freeze their eggs?

  • Women who have not yet found a partner and are not interested in single parenthood.
  • Women interested in delaying pregnancy until they are ready
  • Women with cancer prior to cancer treatment (chemotherapy, radiotherapy)
  • Women at risk for premature ovarian failure
  • Women with a family history of early menopause

How does egg freezing work?

Step 1: Evaluation: Our expert physicians will conduct an evaluation which includes a physical exam, ultrasound, and blood tests. The evaluation assesses your health and ovarian reserve.  

Step 2: Ovarian Stimulation: Based on your results your doctor will develop a stimulation protocol for you. During this process you will administer hormone injections to stimulate your ovaries in order to recruit multiple eggs to be retrieved. Normally your body releases 1-2 eggs each month, however, our goal is to safely retrieve multiple eggs. The stimulation phase lasts approximately two weeks.

Step 3: Monitoring:  Your doctor will monitor the development of your follicles through a series of ultrasounds and blood tests.

Step 4: Retrieval: Once your follicles are ready you will take a “trigger” shot 34-36 hours prior to your retrieval. The egg retrieval process is conducted in a surgery center under light sedation.

Step 5: Freezing: The retrieved mature eggs will be cryopreserved using an advanced freezing method called vitrification to minimize the freezing injury.

Step 6: Storage: Your eggs are stored in liquid nitrogen tanks onsite at Eden. The tanks are monitored 24/7 and back-up systems are used to ensure the care of your eggs.

Other fertility preservation options include embryo freezing, sperm freezing, and ovarian tissue freezing.
