Success rates by age (own eggs)
Live-birth deliveries for patients using their own eggs, 2022. "Per intended retrieval" counts every cycle started with the goal of retrieving eggs, including cycles that did not reach transfer. It is the CDC's most complete measure. How to read these numbers.
- Under 35 26.3%
- 35–37 16.0%
- 38–40 9.7%
- Over 40 0.0%

How the FertilityList Score is built
The score combines four components from CDC data (version 1.0). Each bar shows where this clinic falls on that component, from 0 to 100.
- Age-adjusted outcomes (50%)
- 4
- Experience (cycle volume) (20%)
- 5
- Reporting consistency (15%)
- 100
- Professional standards (15%)
- 50
Age-adjusted outcome ratio: 0.63 (1.00 equals the national rate for the same age mix), based on 134 intended retrievals. Full methodology.
The CDC cautions that comparing clinics may not be meaningful, because clinics treat different patient populations and use different methods. Use these figures as a starting point for questions, not as a prediction of your own chances.
