Study and introduction of family planning methods in developing countries.

Research in developing countries is essential for the evaluation of the safety, efficacy and acceptability of both new and already available contraceptives. Research conducted by scientists in developing countries has also played an essential role in the development of new contraceptives. The continuous delivery of progestin at a low dose, copper IUDs, contraceptive implants, monthly injectables and vaginal rings are examples of new methods developed with the input of research conducted largely in developing countries. When research in developing countries is funded or coordinated by international agencies, local scientists have to be involved not only in its implementation, but in the planning, analysis and dissemination of such research. The World Health Organization, the Population Council and Family Health International have played an important role in supporting collaborative studies for the development, introduction and evaluation of family planning methods in developing countries.
