Birth control refers to methods by which an unplanned or unwanted pregnancy can be prevented. Today various forms of birth control are in existence such as condoms, diaphragms, oral pills, patches and vaginal rings to name a few. While birth control has been around since ancient times, effective and safe methods have only become available in the 20th century.
One such option for birth control in women is the combined oral contraceptive pill (COCP), often referred to as the birth-control pill or colloquially as "the Pill". This is a birth control method that includes a combination of hormones found in women which when taken by mouth have the potential to inhibit pregnancy.
Oral birth control pills were first approved for contraceptive use in the United States in 1960, and are a very popular form of birth control. They are currently used by more than 100 million women worldwide and by almost 12 million women in the United States.
