Real women. Real outcomes.
A plain-numbers calculator built on real return-to-thaw outcomes — women who electively froze their eggs and later came back to use them in IVF.
Adjust the inputs below for your personal estimate.
A woman is born with all the eggs she will ever have. The number falls steadily from before birth, and the proportion of chromosomally normal eggs falls faster — most sharply between 35 and 40. By 42, most retrieved eggs are aneuploid.
Egg freezing is not a guarantee. It is a way of preserving the cells you have today against the certainty of the cells you'll have in ten years. The earlier you do it, the better the eggs you bank, and the fewer cycles you need to bank enough.
The hardest fact: the women who benefit most from egg freezing are those who do it before 35. The women who consult most often are those who are already past 38. We can do it at any age that has eggs to retrieve. We owe you the honest math either way.
One stimulation cycle takes about two weeks from the first injection to the day of retrieval. The egg retrieval itself is a 15-minute outpatient procedure under light sedation. Eggs are vitrified within hours of retrieval and stored in liquid nitrogen at −196°C, where they remain biologically static indefinitely.
The eggs that come out are the eggs that go in — vitrification preserves them with survival rates above 95% in modern labs. Babies born from eggs frozen for 10+ years show the same outcomes as those from fresh eggs of the same age.
Before 35, the curve is forgiving. 12-15 mature eggs gives you a strong shot at one baby. After 38, the same 12 eggs gives you about half that probability. The numbers in the calculator above are calibrated to your exact age — adjust the slider to see how much it shifts.
Each additional child roughly doubles the eggs you'll need. Most patients freezing in their early 30s for one child end up wanting two. Plan for the family you might want, not the family you think you should want.
A high responder in her early 30s can bank 18-22 eggs in one cycle. A 38-year-old with low ovarian reserve may need three cycles to bank the same number. The calculator estimates this for you. If your AMH is known, plug it in for a more honest number.
The published return-to-thaw rate among elective freezers is 12-15% over 5-10 years. The Cobo cohort, which we use for these calculations, includes only women who did return. If you're freezing as a hedge and might never use them, the cost-per-live-birth math is different. We'll talk through it honestly in consultation.
Indefinitely, biologically. At −196°C all metabolic activity stops, so eggs frozen for 12 years behave like eggs frozen for 12 months. Babies have been born from eggs stored over a decade with the same outcomes as fresh eggs of the same age. Storage in Kuwait is regulated and renewed annually with consent.
Most contemporary Sunni and Shia jurisprudence councils permit egg freezing for a married woman within her marriage, with consent of the husband, where the eggs are eventually used in IVF with the husband's sperm. Freezing while unmarried is more debated; we discuss this with each patient individually and can refer to specific fatwas if helpful.
Cycle pricing in Kuwait varies between clinics and medication doses. A single stimulation cycle inclusive of medication, monitoring, retrieval, vitrification, and the first year of storage typically falls in a published range that we confirm at consultation, where we also outline storage fees beyond year one and any multi-cycle package options.
The calculator gives an evidence-based estimate. Your actual outcome will be shaped by several factors the calculator can't see:
The injections sting briefly — most patients describe them as easier than expected. The retrieval itself is done under light sedation and takes about 15 minutes; you won't feel it. The day after retrieval, expect mild bloating and cramping like a heavy period for 1-3 days. Most women return to work within 24-48 hours.
No. Each natural cycle, your body recruits a cohort of eggs and selects one for ovulation; the others are reabsorbed. Stimulation rescues those eggs that would otherwise be lost. You don't lose ovarian reserve from a stim cycle — you simply harvest eggs that were already destined for that month.
Low AMH means fewer eggs per cycle, but it does not change the quality of the eggs we do retrieve. Plenty of women with AMH below 1.0 ng/mL successfully bank enough eggs across two or three cycles. We assess this individually and may recommend specific protocols (estrogen priming, antagonist with growth hormone) that maximise yield in low responders. See our /amh tool for context on what your number means.
Roughly 85-88% of women who freeze electively do not return to use their eggs — most go on to conceive naturally or change their plans. This is normal. The eggs can be discarded with consent at any time, or kept stored indefinitely. Egg freezing is insurance, and many people pay for insurance they never claim.
