All Birth Control pills contain an artificial progestin, which provides most of the contraceptive effect. The progestin thickens cervical mucus to help block sperm from getting to the egg; inhibits ovulation; affects the sperm to make fertilization difficult; and affects the tubes to make it harder for sperm to get to the egg.

Combination birth control pills also contain estrogen, which helps control bleeding and has some impact on ovulation as well.
