Contraception

Birth control, also known as contraception, is designed to prevent pregnancy. Birth control methods may work in a number of different ways:

• Preventing sperm from getting to the eggs. Types include condoms, diaphragms, cervical caps, and contraceptive sponges.
• Keeping the ovaries from releasing eggs that could be fertilized. Types include birth control pills, patches, shots, vaginal rings, and emergency contraceptive pills.
• IUDs, devices which are implanted into the uterus. They can be kept in place for several years.
• Sterilization, which permanently prevents a someone from getting pregnant or from from being able to get someone else pregnant.
