Reproductive health (RH) problems account for a significant part of the burden of disease suffered by poor people in developing countries. Poor women and men are more afflicted with RH problems and often lack access to minimal RH care even when average levels of RH in the country are good. Many RH problems are most cost-effectively managed by prevention - serious problems are costly and very difficult to solve once manifest. This article covers the types of interventions needed to sustain reproductive health including increasing girls' education, preventing and managing sexually transmitted disease, providing contraception to avoid abortion, improving pre-natal and delivery care, increasing the number of skilled providers of health care, post-abortion care, bolstering maternal health services, and reducing practices that increase reproductive health risks such as unsafe sex, female genital mutilation, and domestic violence.
