ResumoThe Family Planning Association of London started a clinical trial to assess the efficacy and acceptability of C-Film as a sole method of contraception. 63 subjects were instructed to use 1 C-Film for each act of intercourse, to use no other contraceptive and to keep a monthly record card on dates of menstruation, days of intercourse, which partner used C-Film, if any, and the presence of vaginal symptoms. 18 of the 63 were not included in the analysis because 3 never cards. 9 of the 45 included in the analysis experienced involuntary pregnancy during a total of 175 person-months, representing a use-effectiveness pregnancy rate of 62/100 woman-years. Only 1 woman admitted to having an unprotected intercourse. A further 25 women withdrew from the trial because of side effects, difficulties with the method or reasons not connected with the method. Due to the unacceptably high failure rate, this study was terminated and the C-Film was not recommended as a sole method of contraception.
