A study was conducted in Dakar, Senegal, to measure reproductive health knowledge and contraceptive use among young adults, and access to family planning services. A household survey was conducted with 1973 single and married women aged 15–24 and 936 single men aged 15–19. Two focus groups and a simulated client study were also conducted. The survey and focus groups noted gaps in knowledge of family planning methods and reproductive health. There were misconceptions about methods and only one-third of men and women aged 15–19 correctly identified the time of the menstrual cycle when a women is most likely to get pregnant. Contraceptive use at time of first premarital sexual experience was less than 30%. The simulated client study noted many barriers to services. ‘Clients’ felt uncomfortable in the clinics and felt that providers were reluctant to take care of them. None of the ‘clients’ who requested contraception received it.
