Teenage pregnancy refers to pregnancy in a female under the age of 20. A pregnancy can take place at any time after puberty, with menarche (first menstrual period) normally taking place around the ages 12 or 13, and being the stage at which a female becomes potentially fertile.

Rates vary between countries because of differences in levels of sexual activity, general sex education provided and access to affordable contraceptive options.
Many health educators have argued that comprehensive sex education would effectively reduce the number of teenage pregnancies, although opponents argue that such education encourages more and earlier sexual activity.
