The pill and sterilization are the leading methods of birth control in the U.S.

A growing percentage of U.S. women are using intrauterine devices, or IUDs, but the pill and female sterilization still lead the contraceptive pack, as they have for nearly a quarter of a century, government researchers reported Wednesday.”We seem to be stuck in a pattern here,” says lead author William Mosher, a statistician with the National Center for Health Statistics, part of the Centers for Disease Control and Prevention.
