New research has revealed a steady increase in the number of donor eggs used for in vitro fertilization in the US between 2000 and 2010, with improved birth outcomes. This is according to a study published in JAMA.
Researchers from the Emory School of Medicine in Atlanta, GA, used data from the Center for Disease Control and Prevention's National Assisted Reproductive Technology (ART) Surveillance System (NASS). This system includes data on more that 95% of all in vitro fertilization (IVF) cycles performed in the US.
The researchers analyzed the data to determine whether there has been an increase in the annual number of donor oocyte cycles during the 10-year period, and whether there has been improved perinatal outcomes.
Good perinatal outcome was defined as a single live-born infant delivered at 37 weeks or later, and weighing 5.5 pounds or more.
