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 | 52.4% |
| Fresh Embryos Frozen Eggs | 9 of 14transfers |
| 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.
What kind of birth, not just whether
A live birth rate tells you how often a transfer worked. It does not tell you whether the result was one baby or twins, and that difference carries most of the medical risk in IVF. The CDC publishes both figures. Clinics advertise only the first.
of donor-egg transfers here resulted in more than one baby. The average across the 329 clinics reporting this is 1.5%, and 65% of them reported none at all.
of transfers produced one baby, carried to term, at a normal birth weight. This is the outcome most people actually have in mind, and it is always lower than the headline rate. The national average is 32.7%.
Single embryo transfer has become standard practice and these numbers show it: most clinics now report no multiple births at all from donor eggs. A figure near zero is normal and good, not a sign of a weak programme.
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.
