About & method

Independent · not a clinic and not affiliated with any fertility provider. Updated June 3, 2026

EggFreezingOdds is an independent editorial project with one job: tell you your honest odds of a live birth from frozen eggs, before you spend a cent. We are not a clinic, we don't take referral fees from any fertility provider, and we have no procedure to sell. That independence is the whole point — most "success rate" pages you'll find are published by clinics that profit when you book.

How the calculator works

Our Egg Freezing Success Calculator runs the peer-reviewed model published by Goldman et al. in Human Reproduction (2017) — the same counseling model behind the Brigham and Women's Hospital / NYU tool used by physicians. It takes your age at freezing and the number of mature eggs you'd bank, then works through the real biological funnel: how many eggs survive thawing, fertilize, become blastocysts, test chromosomally normal, and finally lead to a live birth. We reproduce the model's published figures and show our parameters openly on the how-it-works page.

We always show a range, not a single hopeful number. The model's authors note that real-world frozen-egg results can run about 19% lower than the estimate, because the underlying data came from women who had not yet returned to thaw their eggs. So we display both the model figure and that more conservative figure — and remind you that your clinic's lab is the real variable.

Why there's no doctor's name on our articles

Plenty of sites paste a clinician's photo on a page to look authoritative. We'd rather earn trust a harder way: every clinical claim is tied to a named, dated source you can check yourself — the Goldman model, ASRM and SART/CDC guidance, and published cohort studies. You'll find them all on our sources page. If we can't cite it, we don't claim it. (Securing a named reproductive endocrinologist to review our content is on our roadmap; until then, we lean on the institutions, not a borrowed byline.)

Our principles

  • Honesty over optimism. We lead with the figures clinics bury — that most women never use their eggs, that odds fall steeply after 40, that there's no guarantee.
  • Estimates, labeled as estimates. Numbers here are modeled ranges and cohort averages, never promises.
  • No affiliation, no kickbacks. Nothing on this site changes based on which clinic you choose.
  • Not medical advice. We're a starting point for an informed conversation with a board-certified reproductive endocrinologist — not a replacement for one.
