What is an oral contraceptive pill?

An oral contraceptive ('The Pill') is taken by mouth with the objective of preventing pregnancy. Currently oral contraceptives are taken by women only.

In 1921 it was suggested that extracts from ovaries could be used as oral contraceptives. Diosgenin was first extracted from the Mexican yam in 1941 and this continues to provide a source for the production of sex steroids including norethisterone (norethindrone in the USA) and progesterone (Progest progesterone and progestogen in PMS; progesterone replacement therapy) and Crinone (progesterone and progestogen in PMS).
