Information on Birth Control Pills »
What are birth control pills and how do they work?
Birth control pills are also known as oral contraceptives (OCs) or, simply, “the pill.” They offer protection against pregnancy by blocking the union of sperm and egg, thereby preventing conception.
Oral contraceptives or birth control pills contain synthetic female hormones. They work largely by preventing the release of an egg from an ovary, or ovulation. If no egg is released, there can be no pregnancy.
Stopping ovulation is not the only way birth control pills can work. The progestin or synthetic progesterone in birth control pills also changes the physical and chemical environment of the female reproductive tract, making it hostile for sperm.
What are the different types of birth control pills?
The active ingredients in birth control pills are synthetic versions of the female hormones estrogen and progesterone. Combination oral contraceptives are birth control...

Regular use of the "mini-pill" prevents the release of an egg (ovulation) in about half of the women who use it.
While the "mini-pill" is more effective than certain other methods of birth control (e.g., condom...
