IVF Success Rates by Age (2026 Data)

IVF success rates decline significantly with age.

For women using their own eggs: under 35 — 50–55% live birth rate per cycle; 35–37 — 40–45%; 38–40 — 25–35%; 41–42 — 15–20%; 43+ — 5–10%.

These are per-cycle rates — cumulative success rates over multiple cycles are higher. Clinics are required to report outcomes to the CDC's ART Surveillance System. Always ask for a clinic's live birth rate (not just pregnancy rate) for your age group, as this is the most meaningful metric..
