It's a long list: barrier methods, such as the diaphragm, the "female condom," the cervical cap, the ancient pessary, very ancient Chastity Belt, and The Sponge. There are IUD's: Intrauterine Devices. Sterilization is another option. The "Rhythm Method" is also used. And there are hormonal methods, like Birth Control Pills, injections, implants and cervical rings. Sexual abstinence is also effective.
