Clinical overview
Understanding Egg Freezing
Egg freezing (oocyte cryopreservation) allows women to take control of their biological timeline. Using the same gentle ovarian stimulation protocols as IVF, mature eggs are retrieved and instantly flash-frozen (vitrified) at −196°C in liquid nitrogen. Vitrified eggs remain biologically paused at the age they were frozen, preserving their reproductive potential for years.
Is this pathway likely to be relevant for you?
Situations in which a specialist may suggest discussing this treatment:
- Women wishing to preserve their reproductive options while focusing on career, education, or personal timing
- Individuals facing medical therapies (such as chemotherapy or pelvic surgery) that could impact ovarian reserve
Step by step
What actually happens, stage by stage
Knowing the sequence in advance removes a great deal of anxiety. Timings are typical rather than fixed, and yours will be confirmed by your specialist.
-
Ovarian reserve consultation
AMH and AFC · Initial visit
Testing AMH blood level and antral follicle count to determine realistic egg retrieval numbers.
-
Gentle ovarian stimulation
Daily injections · 9–11 days
Subcutaneous injections over 9 to 11 days to stimulate multiple follicles to mature simultaneously.
-
Ultrasound monitoring
Tracking growth · 3 visits
Three quick ultrasound scans track follicle diameters to choose the optimal trigger day.
-
Egg retrieval
Painless aspiration · 15 minutes
A 15-minute ultrasound-guided retrieval under short sedation to gather mature eggs.
-
Vitrification
Flash freezing · 2 hours after retrieval
Mature eggs are submerged in cryoprotectant and flash-frozen at −196°C within seconds.
-
Secure cryostorage
Long-term safekeeping · Ongoing
Storage in monitored liquid nitrogen tanks until you decide to use them.

Questions answered
Frequently asked about Egg Freezing
Biologically, egg quantity and quality are highest from a woman’s late twenties to her mid-thirties. Women in their late thirties can also freeze eggs effectively, after evaluating their individual AMH and AFC.
Vitrified eggs can remain stored in liquid nitrogen at −196°C for many years without biological degradation in quality.
