Egg freezing is a proactive way to take control of your fertility future. Many people don’t realize that they’re born with all the eggs they’ll ever have. Unlike other cells in the body, eggs don’t regenerate, and both their quantity and quality naturally decrease over time.
Egg freezing offers a way to safeguard your reproductive potential, giving you the flexibility to build your family on your own timeline. While the idea of fertility treatments may feel overwhelming at first, the process is often more manageable than expected. With the right guidance and support, egg freezing can be a straightforward and empowering experience.
What is egg freezing?
Egg freezing, a form of fertility preservation, involves retrieving and freezing your eggs at your current age so they can be used later when you’re ready to move forward with family building. Because egg quality and quantity decline with age, freezing eggs earlier can increase the chance of a successful pregnancy in the future.
What is the typical timeline of the treatment process?
While some circumstances may require a faster treatment path — for example, if you want to freeze eggs before starting chemotherapy or radiation — most people will first meet with a healthcare provider to review their medical history, run initial bloodwork, and complete an ultrasound to assess ovarian reserve and overall reproductive health.
The overall timeline depends on your menstrual cycle. Once your period starts, you can schedule an ultrasound and bloodwork. Based on those results, your provider will review your medication protocol and next steps. Treatment usually begins with the following menstrual cycle. Depending on your protocol, you may start with birth control pills or other medications before beginning stimulation with injectable medicines.
When it’s time to begin ovarian stimulation, you’ll start daily injections for about 9 to 12 days. During this time, you’ll have ultrasounds and bloodwork about every other day so your care team can monitor your progress. These visits usually happen early in the morning, and you’ll receive updates later that day about any medication adjustments and your next appointment.
Once the follicles (small, fluid-filled sacs in the ovary that house and nourish eggs) have grown to the appropriate size, you’ll take a “trigger shot” to help the eggs mature for retrieval — typically about 36 hours before the procedure.
You’ll then come in for the egg retrieval, which takes about 15 to 20 minutes under anesthesia. During the procedure, the care team carefully accesses the ovaries (with ultrasound guidance) through the vaginal wall to collect the fluid containing the eggs. The eggs are then evaluated under a microscope, and mature eggs are frozen for future use.
Afterward, you’ll recover for about an hour before going home. You’ll need someone to drive you and stay with you that day as you recover from anesthesia. Most people feel sore for a couple of days, while others may have mild discomfort for up to a week.
Because not every follicle contains a mature egg — and not all eggs survive the freezing and thawing process — your provider may discuss how many eggs to freeze to optimize your chances of success.
Finding support
While the treatment process can take a physical toll, it can also bring emotional challenges. Although deciding to freeze your eggs can be empowering, it’s normal to experience a range of feelings throughout the process.
Coming to the decision to freeze your eggs can be difficult, and there are often many steps between initial interest and starting treatment. Fertility journeys can sometimes feel isolating, so it’s important to build a support system you can lean on and talk about your experience with.
