Three types of sexually transmitted infections were investigated among 150 family planning clients using different methods of contraception and 50 controls. For oral contraception, intrauterine contraceptive device, medroxyprogesterone acetate (depo-provera) and controls, the incidence of trichomonas was 0%, 6%, 8% and 4%; for gonorrhoea it was 0%, 8%, 2% and 6%; for syphilis it was 4%, 34%, 16% and 12%. Only the difference in prevalence of syphilis among intrauterine contraceptive users and control was statistically significant (P less than 0.3).
