Egg freezing is about two weeks of hormone injections and monitoring, ending in a sedated egg-collection procedure, with most patients under 38 collecting 7 to 14 eggs.
The process mirrors the front half of IVF. Testing first: AMH bloodwork and an ultrasound to plan doses. Then roughly 10 to 14 days of daily self-injected hormones to mature multiple eggs, with monitoring scans and blood draws every few days. A trigger shot times ovulation, and about 36 hours later the eggs are collected through the vaginal wall under sedation or general anesthesia, a 15 to 30 minute procedure with same-day discharge and a couple days of cramping. Eggs are vitrified (flash-frozen) and stored in liquid nitrogen until you want them, at which point they are thawed and fertilized. Know the risks plainly: stimulation side effects are usually mild, but ovarian hyperstimulation syndrome is the rare dangerous one, so learn its warning signs. And freezing preserves a chance, not a promise: thaw survival, fertilization, and pregnancy each take their share, and the age you freeze shapes the odds more than any other factor.
What to do
Common questions
What is egg freezing like?
Egg freezing is roughly a two-week process structured like the first half of IVF, minus the embryo part. It starts with testing: bloodwork (including AMH) and an ultrasound to estimate your egg supply and plan medication doses. Then comes stimulation: about 10 to 14 days of daily self-injected hormone shots that push your ovaries to mature many eggs at once instead of the usual one, with monitoring appointments every few days (blood draws and transvaginal ultrasounds) to watch follicle growth and adjust doses. When the eggs are ready, a trigger shot times the finish, and about 36 hours later comes collection: a needle procedure through the vaginal wall under sedation or general anesthesia, typically 15 to 30 minutes, same-day discharge, and a day or two of cramping after. The eggs are flash-frozen (vitrification) and stored in liquid nitrogen. Most patients under 38 have around 7 to 14 eggs collected, though low reserve yields fewer. Honest caveats: side effects from stimulation are usually mild (bloating, mood shifts, soreness), but ovarian hyperstimulation syndrome is the rare serious risk, so learn its symptoms. And frozen eggs are not a guarantee: survival on thawing, fertilization, and pregnancy each carry their own attrition, and age at freezing matters more than almost anything else.
