Why people freeze eggs
Egg freezing preserves mature eggs for future use. Reasons include planning around age-related fertility changes, preserving fertility before medical treatment that may affect ovarian function, and preserving eggs before gender-affirming care.
The process
A typical elective cycle takes about two weeks and involves ovarian stimulation, monitoring, egg retrieval, and cryopreservation of mature eggs by vitrification. Most patients continue normal activities during the cycle with modifications around retrieval.
Age and outcomes
Egg quality and quantity change with age. Freezing eggs earlier generally yields more usable eggs per cycle. Your physician will review your ovarian reserve testing and discuss realistic expectations before you decide whether to proceed.
Using frozen eggs later
When you are ready to try for pregnancy, frozen eggs are thawed, fertilized in the lab (typically with ICSI), and cultured to embryos for transfer. Frozen eggs do not guarantee a future pregnancy — success depends on multiple factors your physician will review with you.
Questions to ask
What is my ovarian reserve today? How many mature eggs are we aiming to bank, and why? What are storage, thaw, and future-use costs? What are the medical and emotional considerations of doing one cycle versus two?
What to expect
- 01
Initial evaluation
Ovarian reserve testing (AMH, antral follicle count), a baseline hormone panel, and a review of your medical history set the plan and the target number of eggs to bank.
- 02
Cycle start
The cycle begins with either the natural period or a short priming step. Injectable hormones develop multiple follicles over roughly ten to twelve days.
- 03
Monitoring visits
Short ultrasound and blood-work visits confirm response and adjust medication doses. Most patients can continue school or work with modest schedule flexibility.
- 04
Trigger and retrieval
A precisely timed trigger injection is followed by egg retrieval under sedation about 36 hours later. The retrieval itself takes about 15–20 minutes.
- 05
Vitrification and storage
Mature eggs are vitrified within hours of retrieval and stored in the cryopreservation lab. You receive a summary of how many mature eggs were banked.
- 06
Future use
When you are ready, eggs are thawed, fertilized (typically with ICSI), and cultured to embryos for transfer. Any remaining embryos can be frozen.
