How to read this data
Success rates vary by patient age, diagnosis, and treatment protocol. Figures are clinic-wide averages for patients using their own eggs — your personal outcome depends on factors a board-certified reproductive endocrinologist can assess. National averages are computed across all ~370 reporting US clinics in our directory with published 2022 CDC data. 0% values may reflect too few cycles to report reliably at that age band.
