How Many IVF Cycles to a Baby?
Cumulative probability of a live birth after 1 through 5 IVF cycles, by patient age band. Based on national weighted-average live birth rates from 452 CDC-reporting clinics (2022 data).
National average cumulative success by cycle count
| Age band | Per-cycle LBR | 1 cycle | 2 cycles | 3 cycles | 4 cycles | 5 cycles | Expected cycles |
|---|---|---|---|---|---|---|---|
| Under 35 | 49.3% | 49.3% | 74.3% | 86.9% | 93.4% | 96.6% | 2.0 |
| 35–37 | 35.7% | 35.7% | 58.7% | 73.4% | 82.9% | 89.0% | 2.8 |
| 38–40 | 23.0% | 23.0% | 40.7% | 54.4% | 64.9% | 73.0% | 4.3 |
| Over 40 | 7.9% | 7.9% | 15.1% | 21.8% | 27.9% | 33.6% | 10.0 |
Cumulative probability = 1 - (1 - per-cycle LBR)^n. Expected cycles = 1 / per-cycle LBR. National averages are weighted by each clinic’s reported cycle volume.
