Success rate lookup

Choose a clinic and an age band. You get the CDC-reported percentage of intended egg retrievals that ended in a live birth, the cumulative rate for patients new to ART, the number of retrievals behind the first figure, and the US figure for the same band.

US figures by age band (2022)

The CDC's national aggregate, the same numbers the tool compares against:

Age band	Live births per intended retrieval	New patients: live birth after all retrievals
Under 35	49.7%	60.8%
35–37	36.3%	49.9%
38–40	23.1%	35.2%
Over 40	7.7%	13.4%

How it works

The tool reads a 28 KB table embedded in this page, generated from the CDC National ART Surveillance System 2022 Final release (released Dec 18, 2024): for each clinic and age band, the live-birth rate per intended egg retrieval, the number of intended retrievals, and the cumulative live-birth rate for new patients after all intended retrievals. Where the CDC printed a fraction (it does so for rates with denominators less than 20) the tool prints the same fraction; where the CDC suppressed a cell it prints a dash; where it reported no cycles it prints “No cycles reported”. Nothing is estimated and no clinic is scored. Open the clinic's page for every other measure, donor-egg rates and the cycle summary.

CDC: ART success rates is the primary source. This site is an index of public data, not medical advice. Nothing here can tell you which clinic is right for you; discuss your own history, diagnosis and options with a reproductive endocrinologist.

What the measures mean

Intended egg retrieval: A cycle started “with the plan to retrieve eggs”, counted whether or not any eggs were retrieved, so cancelled cycles stay in the denominator. Rates per intended retrieval are cumulative: they count live births from every embryo transfer within 1 year after that retrieval, fresh or frozen.
Egg retrieval (actual): “A procedure to collect the eggs contained in the ovarian follicles.” Rates per actual retrieval are cumulative in the same way but leave out cycles cancelled before retrieval, so they are never lower than the rate per intended retrieval.
Transfer: “Placement of embryos into a woman's uterus through the cervix after IVF.” A rate per transfer counts each transfer on its own, so cycles that never reached a transfer are not in it. It is not always the highest rate: in 2022 the US figure for patients under 35 was 49.1% per transfer against 49.7% per intended retrieval. In the older bands, where many cycles never reach a transfer, it is usually higher (over 40: 25.4% per transfer, 7.7% per intended retrieval).
Live-birth delivery: “The delivery of one or more infants with at least one born alive.” A singleton live-birth delivery is “the delivery of a single infant born alive.”
New patients: cumulative outcomes: Patients with no prior ART, followed through one, two, or all of their intended retrievals, counting transfers of fresh or frozen embryos from those retrievals. This is the closest the report comes to “my chance of a baby from starting treatment”.
Age bands: The CDC groups patients using their own eggs as under 35, 35 to 37, 38 to 40, and over 40, because egg quality falls with the patient's age. Donor-egg rates are not split by age: the donor's age drives them, not the patient's.
