The ability to determine if and when to become pregnant, is vital to a woman's autonomy and well being, and contraception can protect girls and young women from the risks of early pregnancy and older women from the increased risks of unintended pregnancy. Adequate access to contraception can limit multiple pregnancies, reduce the need for potentially unsafe abortion and reduce maternal and infant mortality and morbidity. Some barrier forms of contraception such as condoms, also reduce the risk of STIs and HIV infection. Access to contraception allows women to make informed choices about their reproductive and sexual health, increases empowerment, and enhances choices in education, careers and participation in public life. At the societal level, access to contraception is a key factor in controlling population growth, with resultant impact on the economy, the environment and regional development.[58][59] Consequently, the United Nations considers access to contraception a human right that is central to gender equality and women's empowerment that saves lives and reduces poverty,[60] and birth control has been considered amongst the 10 great public health achievements of the 20th century.[61]

Women with ovaries but no uterus may be able to use a gestational carrier. This may also be an option for women who shouldn't become pregnant because of a serious health problem. In this case, a woman uses her own egg. It is fertilized by the man's sperm and the embryo is placed inside the carrier's uterus. The carrier will not be related to the baby and gives him or her to the parents at birth.
