  • Description:

    Since the first U.S. infant conceived with assisted reproductive technology (ART) was born in 1981, both the use of ART and the number of fertility clinics providing ART services have increased steadily in the U.S. ART includes fertility treatments in which eggs or embryos are handled in the laboratory (i.e., in vitro fertilization [IVF] and related procedures). Although the majority of infants conceived through ART are singletons, women who undergo ART procedures are more likely than women who conceive naturally to have multiple-birth infants because multiple embryos may be transferred. Multiple births can pose substantial risks for both mothers and infants, including obstetric Complications, preterm birth (<37 weeks), and low birthweight (<2,500 g). This report provides state-specific information for the U.S. (including the District of Columbia and Puerto Rico) on ART procedures performed in 2017 and compares birth outcomes that occurred in 2017 (resulting from ART procedures performed in 2016 and 2017) with outcomes for all infants born in the U.S. in 2017.

    Description of System

    In 1995, CDC began collecting data on ART procedures performed in fertility clinics in the U.S. as mandated by the Fertility Clinic Success Rate and Certification Act of 1992 (Public Law 102–493 [October 24, 1992]). Data are collected through the National ART Surveillance System (NASS), a web-based data collection system developed by CDC. This report includes data from the 50 states, the District of Columbia, and Puerto Rico.


    In 2017, a total of 196,454 ART procedures (range: 162 in Alaska to 24,179 in California) with at least one embryo transferred were performed in 448 U.S. fertility clinics and reported to CDC. These procedures resulted in 68,908 live-birth deliveries (range: 67 in Puerto Rico to 8,852 in California) and 78,052 infants born (range: 85 in Puerto Rico to 9,926 in California). Nationally, the number of ART procedures performed per 1 million women of reproductive age (15–44 years) was 3,040. ART use rates exceeded the national rate in 14 states (Connecticut, Delaware, District of Columbia, Hawaii, Illinois, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, Utah, Vermont, and Virginia). ART use exceeded 1.5 times the national rate in seven states (Connecticut, the District of Columbia, Illinois, Maryland, Massachusetts, New Jersey, and New York).


    Although singleton infants accounted for the majority of ART-conceived infants, multiple births from ART still contributed to a substantial proportion of all twins, triplets, and higher-order infants born in the U.S. Variations in SET rates among states and territories were noted, reflecting variations in embryo-transfer practices among fertility clinics, which might in part account for higher multiple birth from ART observed in some states and territories.

    Public Health Action

    Reducing the number of embryos transferred and increasing use of SET, when clinically appropriate, can help reduce multiple births and related adverse health consequences for both mothers and infants. Because infants from multiple births are at increased risk for numerous adverse sequelae that cannot be ascertained from the data collected through NASS alone, long-term follow-up for ART infants through integration of existing maternal and infant health Surveillance systems and registries with data available from NASS might be useful for monitoring adverse outcomes on a population basis.
