Egg Freezing in the UK: Costs, Success Rates and What Nobody Tells You
Egg freezing has shifted from a niche medical procedure to something your colleagues discuss at lunch. Clinics market it as an insurance policy. Employers offer it as a benefit. The message is simple: freeze your eggs now, use them later, problem solved. The reality is more nuanced than that, and the numbers deserve a clear-eyed look.

What it actually costs
A single egg freezing cycle in the UK typically costs £3,000 to £5,500 for the procedure itself. Add medication (£500–£1,500), initial consultations and blood tests (£300–£600), and sedation or anaesthesia for egg collection (often included, sometimes not). Then there's annual storage: £150–£400 per year, every year, until you use them or decide not to.
Most women under 36 need one to two cycles to bank enough eggs for a reasonable chance of a future pregnancy. Over 36, you may need two to three. So the real cost isn't one cycle — it's potentially £8,000 to £15,000 before you've even attempted to use the eggs.
The age question
This is the part that gets glossed over. Egg freezing works best when you do it youngest, but you're least likely to need it then. The sweet spot — if there is one — is between 30 and 35. Before 30, most women produce plenty of eggs but are statistically likely to conceive naturally anyway. After 37, egg quality drops significantly, meaning you need more cycles to get fewer viable eggs.
Freezing at 38 is not the same as freezing at 32. A 32-year-old might get 12–15 eggs per cycle with a reasonable expectation that 60–70% will survive thawing. A 38-year-old might get 6–8 eggs per cycle with lower survival and fertilisation rates. The maths changes dramatically.
Survival, fertilisation and live birth — the funnel
Here's where the marketing diverges from the data. If you freeze 15 eggs at age 33, roughly 80% survive the thaw (12 eggs). Of those, maybe 70% fertilise with ICSI (8 embryos). Of those, perhaps 40–50% develop to a viable blastocyst (3–4 embryos). And the implantation rate per blastocyst transfer is around 30–40%. Run the numbers and 15 frozen eggs give you a roughly 70–80% cumulative chance of at least one live birth.
Those are decent odds — but they require 15 good-quality eggs from a woman in her early thirties. Change any of those variables (fewer eggs, older age, lower quality) and the probability drops fast. Freezing 6 eggs at 38 might give you a 20–30% chance. Not nothing, but not the insurance policy the brochure implied.
The storage rule change
Until 2022, UK law limited egg storage to 10 years. That created an absurd situation where women who froze at 28 had to use or discard their eggs by 38 — exactly when they might need them. The law has since changed to allow storage for up to 55 years, which removes that particular pressure. You'll still pay annual storage fees, but the clock is no longer ticking in the same way.
What clinics don't always mention
Most women who freeze their eggs never use them. Studies consistently show that only 10–15% of women return to use their frozen eggs. Some conceive naturally. Some decide not to have children. Some use donor eggs instead because their frozen eggs, collected at an older age, don't yield enough embryos.
That doesn't make egg freezing pointless. For many women, the psychological value of having options is real and worth the cost. But it's important to go in understanding that this is a probability game, not a guarantee — and the probabilities depend heavily on age at freezing and the number of eggs banked.
Comparing clinics for egg freezing
When choosing a clinic, look at the total package cost (not just the headline cycle price), the number of cycles other patients typically need, and whether storage fees are included in the first year. Ask about their egg survival rates after thawing — this varies between labs and reflects the quality of their vitrification technique. On Vero Fertility, you can filter clinics by egg freezing services and compare all-in pricing side by side.
