The United States Food and Drug Administration (FDA) lifts the 32-year-old, lifetime ban on blood donations from gay and bisexual men. Men can donate if they haven't had sex with another man in the previous year. The FDA stance is in line with other countries, such as Australia, Brazil, Canada, New Zealand, and the U.K., and is consistent with rules on recent blood transfusion or accidental exposure to another individual's blood.
