U.S. Test-Tube Births Underreported by State, Study Finds

December 11, 2014

(Reuters) – The number of test-tube babies born each year in the United States is underreported by states, a new federal study found on Wednesday, complicating efforts by researchers to understand the risks associated with pregnancies resulting from in vitro fertilizations. The research by the National Center for Health Statistics compared birth certificate data in 27 states and Washington, D.C., with the numbers from a federal survey of the medical clinics that use assisted reproductive technology to join eggs and sperm in a laboratory dish.
