| Age range | Approximate live birth rate per transfer (own eggs) |
|---|---|
| Under 35 | 50–60% |
| 35–37 | 38–45% |
| 38–40 | 25–35% |
| 41–42 | 15–25% |
| 43+ | 5–15% |
These are general, published ranges — individual clinic and patient outcomes vary. Ask any clinic for their specific age-adjusted data, not a general industry figure.
Why "success rate" needs a precise definition
Clinical pregnancy rate, live birth rate per transfer, and cumulative live birth rate across multiple cycles are all different measures — a rate quoted without specifying which one it measures isn't meaningful for comparison.
Why donor egg options change this picture
Success rates using donor eggs remain relatively stable across recipient age (typically 50–65%), since egg age — not uterine age — is the primary age-related factor. This is worth knowing as context, not a recommendation for your specific situation.

The Takeaway
Ask any clinic specifically which measure their quoted rate reflects, and for data adjusted to your specific age — a general industry number isn't a reliable predictor for you individually.
