Correctly using male (also called external) condoms and other barriers like female (also called internal) condoms and dental dams, every time, can reduce (though not eliminate) the risk of sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV) and viral hepatitis. They can also provide protection against other diseases that may be transmitted through sex like Zika and Ebola. Using male (external) and female (internal) condoms correctly, every time, can also help prevent pregnancy.
This website provides information for both consumers and public health professionals on the correct use of male (external) and female (internal) condoms and dental dams, as well male (external) condom effectiveness for STDs, and links to additional resources.
