Birth Control Methods: Intrauterine device: An intrauterine device (IUD) is a small device that is placed in the uterus to prevent pregnancy. There are two main types of IUDs: copper IUDs (such as ParaGard) and hormonal IUDs (such as Mirena or Skyla). When an IUD is in place, it can provide birth control for 3 to 10 years, depending on the type. BarBarrier methods (including the diaphragm; cervical cap; male condom; female condom; and spermicidal foam, sponge, gel, suppository, or film) prevent sperm from entering the uterus and reaching the egg. Typically, barrier methodsare not highly effective, but they generally have fewer side effects than hormonal methods or IUDs. Spermicides and condoms should be used together or along with another method to increase their effectiveness. Barrier methods can interrupt sex, because they must be used every time you have sex. Periodic abstinence or natural family planning. Withdrawal (pulling out) is a behavioral form of birth control where the man removes his penis from the vagina before ejaculating. Condoms are a barrier method designed to capture ejaculate before it enters the vagina.
