Today, in its Morbidity and Mortality Weekly Report, the U.S. Centers for Disease Control and Prevention released its Assisted Reproductive Technology Surveillance Summary for 2009.
In 2009, a total of 146,244 ART procedures were reported to the CDC and they resulted in 45,870 live-birth deliveries and 60,190 infants, or 1.4 % of U.S. births.
The average number of embryos transferred was 2.1 among women <35 years, 2.5 among women 35–40 years, and 3.0 among women >40 years. Elective single-embryo transfer rates were approximately 7% among women <35 years, 3% among women 35–40 years, and 0.5% among women >40 years. Among infants conceived with ART, 33.4% were born preterm, compared with 12.2% of the general birth population.
The summary identifies as a public health action the promotion of single-embryo transfer, where feasible, to reduce multiple births and related adverse consequences of ART. However, it concludes that because ART accounts for a relatively small fraction of total births, the overall prevalence of low birth weight and preterm births cannot be explained solely by the use of ART, and therefore non-ART causes of these adverse outcomes must be examined, including the monitoring of non-ART infertility treatments.
