The Assisted Reproductive Technology Surveillance - United States, 2015 summary in CDC's Morbidity and Mortality Weekly Report (MMWR) released today presents state-specific data on assisted reproductive technology (ART) use and outcomes.

The report compares ART infant outcome data with outcomes for all infants born in the U.S. in 2015. It also provides data on the contributions of ART to total infants born, multiple birth infants, low birth weight infants, and preterm infants for each U.S. state, the District of Columbia, and Puerto Rico. In addition, the report looks at elective single embryo transfer procedures that can help reduce multiple births from ART treatments, and can be considered an important approach for improving outcomes for moms and babies.

Findings include:

In 2015, 1.7% of all infants born in the United States were conceived with ART.

Approximately, 35% of ART infants were born in multiple births compared with 3% among infants born in the general population.

A greater proportion of ART infants were low birth weight (26%), and preterm (31%), compared with infants in the birth population overall (8% and 10%, respectively), mainly due to a higher rate of multiple births.

Nationwide, the percentage of elective single embryo transfer increased from 7.4% in 2009 to 34.7% in 2015 among women aged <35 years. From 2014 to 2015, the percentage of elective single embryo transfer among women aged <35 years increased by approximately 22.0%.
