American clinics call it the CDC report. Reporting is federal law, and the law was passed because clinics were advertising their own numbers.

What every reporting fertility clinic in the United States did in a year, and what came of it. "The Fertility Clinic Success Rate and Certification Act of 1992 mandates that clinics performing ART annually provide data to CDC for ART procedures they perform", and the CDC calculates standardised success rates from the returns. The most recent final year is 2022: "In 2022, there were 435,426 ART cycles performed on 251,542 unique patients at 457 reporting U.S. clinics."

The story Cited · cdc-nass

Those cycles produced 94,039 live-birth deliveries and 98,289 live-born infants, about 2.6% of all infants born in the United States that year. A further 184,423 of the reported cycles were egg or embryo banking, where everything was frozen for later.

Compliance is not complete: "A small number of clinics do not report data to CDC and are listed as nonreporters", and because most of those are small the CDC estimates the system "contains information on about 98% of all ART cycles in the United States". A register with a statute behind it still names the clinics that will not answer.

And like its British counterpart the CDC publishes the table under a warning: "Comparison of success rates across clinics may not be meaningful", and "Clinic success rates do not reflect any one patient's chance of success". Its reasons are the ones that defeat every clinic league table — different patients, different selection, different methods, rates that reflect cycles more than a year old, and small clinics whose numbers swing on a handful of cases.

Inference — for this site the series is a benchmark rather than a destination record. It gives a dated, statutory, per-clinic figure for the country most fertility travellers leave rather than enter, which makes it the sharpest available measure of what a patient gives up by travelling to a market that publishes nothing comparable.

Notes

ART is defined narrowly: treatments in which eggs or embryos are handled. Treatment in which only sperm are handled — intrauterine insemination — is outside it, as is ovulation induction with drugs alone.

countsEvery ART cycle performed at a reporting United States clinic in the calendar year — cycles, patients, transfers, live-birth deliveries and infants — reported clinic by clinic and nationally. National figures are noncumulative and cover only cycles performed in the reporting year.
does not countAnything done outside a United States clinic. A US resident who travels to Mexico, Spain, Greece or the Czech Republic for IVF is outside the system entirely, and no American series counts them. It counts no intrauterine insemination and no ovulation induction, because neither is ART by CDC's definition; it counts nothing from the clinics listed as nonreporters, about 2% of cycles by CDC's own estimate; and its clinic rates describe cycles more than a year old, which the CDC says plainly should not be read as any individual's chance of success.
