Millions of ART treatment cycles occur annually, with live-birth rates below 50%.

The Claim

Each year, millions of people undergoing infertility treatment use assisted reproductive technology (ART), and most of those people do not have a live birth.

Verified by Lenz ·

The Short Version

The claim is broadly supported when read as an annual statement. International and national ART registries show millions of treatment cycles each year worldwide, making millions of patients plausible, and annual live-birth success rates are generally well under 50%. The main caveat is that global data usually count cycles rather than unique people, and cumulative success after multiple cycles can be higher than annual results.

Caveats

  • Global ART totals usually measure treatment cycles, not unique patients, so the "millions of people" figure is an informed estimate rather than a directly reported worldwide count.
  • "Most do not have a live birth" is strongest when interpreted per year or per cycle; it is not the same as lifetime success after multiple cycles.
  • Older linked-cycle studies in some populations show that more than half of patients may eventually achieve a live birth after several cycles, so the claim should not be read as a statement about ultimate outcomes.
