A birth control device is a tool used to prevent pregnancy. Examples include condoms, which are worn on the penis to catch sperm; diaphragms and cervical caps, which are placed inside the vagina to block sperm from reaching the egg; and intrauterine devices (IUDs), which are inserted into the uterus to prevent a fertilized egg from attaching. These devices help prevent pregnancies and can also offer protection against sexually transmitted infections (STIs), depending on the type.
