OBJECTIVES: To investigate young male students' behaviour, knowledge, attitudes, and needs related to sexual and reproductive health (SRH). Differences between students on vocational and academic study programmes were also investigated. METHOD: A questionnaire consisting of 87 multiple choice questions was distributed to 253 male students attending three upper secondary schools in a single Swedish county. RESULTS: A response rate of 76% (n = 192) was achieved. Vocational students displayed more risk behaviour than those in academic study programmes regarding use of tobacco and sexual behaviour. Eighteen percent of those who were sexually experienced had suggested or provided the emergency contraception pill (ECP) to a girl. Insufficient knowledge of sexually transmitted infections (STIs) was identified, especially among the vocational students. No one reported the upper secondary school as their main source of knowledge and both groups requested more information about both genders' reproductive systems, and STIs. Some discriminatory attitudes regarding gender equality in SRH matters were identified. Both groups stated that male-friendly Youth Health Clinics (YHCs), easier access to condoms and Internet-service for Chlamydia test are important. CONCLUSIONS: Improvements in the quality and quantity of sex education in upper secondary schools are needed; they should be tailored to the spectrum of students' situations and needs. A structure of the YHC adapted to male youths' needs and alternative, easily accessible STI tests are important factors for reaching young men and having them participate in a responsible way in protecting their own and their partners' SRH.
