In 1992, the US Congress passed the Fertility Clinic Success Rate and Certification Act. This law requires the Centers for Disease Control and Prevention (CDC) to publish pregnancy success rates for assisted reproductive technology (ART) fertility clinics in the United States. More details about the law are available online at CDC’s Fertility Clinic Success Rate and Certification Act website.

Since 1995, CDC has worked in consultation with the Society for Assisted Reproductive Technology and the American Society for Reproductive Medicine to report ART success rates. This report is based on the latest available data on the type, number, and outcome of ART cycles performed in US clinics.

The 2020 Assisted Reproductive Technology Fertility Clinic and National Summary Report has four major sections:

Commonly Asked Questions About the US National ART Surveillance System

This section provides background information on infertility and ART; an explanation of the data collection, analysis, and publication processes; and links to resources for people experiencing infertility or people interested in ART.

How to Access and Interpret Fertility Clinic Success Rates

This section provides information on how to access and interpret fertility clinic success rates presented online for each reporting fertility clinic in the United States. It provides an overview of services and a profile for each reporting fertility clinic, the characteristics of the patient population, and detailed explanations about success rates covering various aspects of fertility treatments.

The National ART Summary section displays ART results and success rates from data combined from all US clinics. The summary table and figures use ART data from all reporting clinics to answer specific questions related to ART use and outcomes.
