Birth Control

There are many types of contraceptive techniques in use today - none of which are 100% effective. Many concentrate on keeping sperm out of the uterus. For example diaphragms and condoms are designed to provide a physical barrier. Spermicides or sponges provide a chemical barrier. Natural Family Planning (NFP) modifies the sexual act itself. Other techniques, hormonal methods, concentrate on interfering with the ovum. The oral contraceptive pill affects the ovum's development and release, an injection type such as Depro-Provera and Lunelle suppresses ovulation or an implant such as Norplant also suppresses ovulation. The Intrauterine devices (IUD) help to prevent the fertilized egg from implanting in the uterus. When used correctly condoms are just as effective.
