The CDC publishes this as a count rather than a percentage, because it rests on fewer than twenty transfers. That works out at 31.3%, but at this sample size one extra birth moves the figure by several points. Treat it as a rough signal, not a measurement, and weigh it against clinics doing hundreds of cycles.
By type of cycle
The CDC splits donor results by what was actually transferred. Frozen embryo transfer is the dominant modality in current practice.
| Frozen Embryos | 5 of 16transfers |
| Fresh Embryos Frozen Eggs | Not reported |
| Fresh Embryos Fresh Eggs | Not reported |
| Donated Embryosembryo donation, not egg donation | Not reported |
Using her own eggs, by age
The same measure at this clinic for patients using their own eggs. The gap that opens after 40 is the reason donor eggs exist.
Every figure on this page is published by the CDC, not by the clinic and not by us. Source: CDC Assisted Reproductive Technology (ART) Success Rates, 2022 final release. A cell the CDC suppressed shows “Not reported” rather than 0%, and a rate from fewer than twenty transfers is shown as a count rather than a percentage. This page is not a recommendation, a ranking or a quality judgement, and no clinic can pay to change it. See how we read the data.
