How many eggs should you freeze?

A quick, education-only estimate of how many mature eggs it typically takes to reach a chosen chance of a future live birth — based on published fertility research, not a personal prediction. Adjust the sliders below to see how age, your family goals, and how "sure" you want to be all change the number.

to give you an estimated 90% chance of at least 2 future live births, based on a 34-year-old's published outcomes.

This combination lands well outside what published studies have measured directly — treat it as a rough, extrapolated ballpark and talk it through with a reproductive endocrinologist.

How this changes with age

Same family goal and confidence level, shown across ages — your age is highlighted.

Bars above ~100 eggs are capped and labeled — at that point, most patients and physicians are weighing multiple retrieval cycles, donor eggs, or other paths, not just "freeze more."

Where these numbers come from & what they don't mean

The core estimate models each mature frozen egg as an independent chance at a future live birth, with that chance declining by age — calibrated to published live-birth-probability data from Goldman et al., Human Reproduction 2017, and cross-checked against Doyle et al., Fertility and Sterility 2016 (the study ASRM's own 2021 guideline cites). Ages roughly 32–42 are close to directly-published data points; ages under ~28 and over ~43 are extrapolated using the shape of published age-vs-egg-quality curves, since few studies report outcomes at those extremes.

The cycles estimate uses rough eggs-per-cycle bands from a 2025 Human Reproduction yield-prediction model (age + AMH + AFC + FSH, ~915 cycles) — it's a planning ballpark, not a personal prediction, since actual yield varies a lot by clinic protocol and cycle-to-cycle.

What this tool intentionally does not do: adjust the core number for BMI, smoking, PCOS, or endometriosis. Those factors have real evidence tying them to how many eggs one retrieval cycle produces — but not to how many eggs you need banked for a given live-birth chance, independent of age. ASRM's guideline is explicit that there's insufficient evidence to make that second kind of adjustment, so we'd rather show you an honest age-based number than a falsely precise one.

This is an educational estimate built from population-level research, not a personalized medical prediction. Your own numbers can differ based on factors this tool doesn't capture. Please review your specific situation with a reproductive endocrinologist.
