It was evaluated knowledge, attitude and practice concerning contraceptive pills and preservatives among teenagers at a public University of São Paulo. A questionnaire was applied for 295 students. We verified that teenagers presented a positive attitude as to contraceptive practices because 92,6% of them said that adolescents should use contraceptive methods, and among those who had already initiated their sexual activities, 82% answered that they always used some type of contraceptive during their sexual intercourses. They showed higher knowledge than practice. Comparing the pill to preservative, we noticed that adolescents presented a greater knowledge and practice regarding preservatives. It was concluded that although they have corrects knowledge and practice, they need modified some of their practices for an effective contraception.
