The egg freezing process is relatively simple.
Consultation - Your doctor will check your ovarian reserve with a blood test that looks at your Follicle Stimulating Hormone (FSH), Estradiol, and Anti-Mullerian Hormone (AMH) levels. You may also undergo a transvaginal ultrasound for an antral follicle count. Each of these tests are used to determine if you have a sufficient number of oocytes (eggs) awaiting maturation and can be retrieved.
Drug Regimen - For 7 to14 days, you will begin using fertility drugs. This depends on how well you respond to the self-administered hormone injections. During this time, as your follicles begin to grow, you will feel some bloating. This is perfectly normal and your doctor will monitor you regularly using blood tests and ultrasounds.
Retrieval and Freezing - This is the easy part. While you are under anesthesia, your doctor will use an ultrasound guided needle to aspirate the mature eggs from the follicles. This process only takes around 30 minutes. Afterward, you might feel some cramping and will be instructed to take it easy for the next couple of days. The eggs recovered from the retrieval are immediately frozen using a process called vitrification used at technologically advanced clinics. By using vitrification your eggs will be "flash frozen" to keep the eggs from forming ice crystals, which can cause damage. Eggs frozen this way can be successfully used to achieve pregnancy for up to ten years or more.
