计划生育
Family planning has been of practice since the 16th century by the people of Djenné in West Africa. Physicians advised women to space their children, having them every three years rather than too many and too quickly. Other aspects of family planning include sex education, prevention and management of sexually transmitted infections, pre-conception counseling and management, and infertility management. Family planning, as defined by the United Nations and the World Health Organization, encompasses services leading up to conception. Abortion is not a component of family planning, although access to contraception and family planning reduces the desire for abortion.
