The Basics
How does birth control work?
It depends on the type of birth control you use. Here are some of the most common methods of birth control.
Abstinence
Abstinence means that you don’t have vaginal, anal, or oral sex. This is the only sure way to prevent pregnancy. It’s also the best way to protect yourself from STDs.
Barrier methods
Barrier methods work by preventing the sperm and egg from touching each other. Common barrier methods include:
- Male condoms (worn on the penis)
- Female condoms (placed on the outside and inside of the vagina)
- Birth control diaphragm (placed inside the vagina)
