Birth control pill and other hormonal contraceptives
Oral contraceptives have been used in Canada since 1960 to help prevent unwanted pregnancy. Today the pill is the most popular form of birth control in Canada and the United States, used by nearly 20% of women aged 15–49.
The birth control pill contains manufactured versions of 2 female hormones – estrogen and progesterone. This type of pill is called combined hormone contraception. The hormones work together to prevent pregnancy by inhibiting the release of eggs from the ovary.
