Birth control, also known as contraception or family planning, is a way for a man and woman to have sexual intercourse without the woman getting pregnant.
Some contraceptives, such as condoms, also protect a person from sexually transmitted diseases (STDs). When people use contraception to prevent STDs and pregnancy, it may be called safe sex.
Birth control is also sometimes called family planning. It means people can have babies or not as they wish. That way, babies and families do not happen by accident.
