• Birth control pills prevent pregnancy through several mechanisms, mainly by stopping ovulation. If no egg is released, there is nothing to be fertilized by sperm, and the woman cannot get pregnant. Most birth control pills contain synthetic forms of two female hormones: estrogen and progestin. Barrier methods of birth control block sperm from entering the uterus.
• Barrier methods include the diaphragm, cervical cap, cervical shield, male condom, and female condom and spermicidal foam, sponges, and film.
• Vasectomy is a surgical procedure for male sterilization or permanent contraception. During the procedure, the male vasa deferentia are severed and then tied/sealed in a manner so as to prevent sperm from entering into the seminal stream (ejaculate) and thereby prevent fertilization.
• The Copper-T IUD does not affect ovulation, but it can prevent sperm from fertilizing an egg. It may also prevent implantation of a fertilized egg.
