RESULTS: A total of 367 valid questionnaires were collected and the mean age of respondents was 20.5 ± 1.8 years. The reproductive physiology knowledge and contraceptive knowledge score of the subjects were lower, but there was no significant difference between men and women (P> 0.05). The STD / AIDS knowledge score was higher, and the median male score (76.9) was higher than that of women (69.2) , The difference was statistically significant (P <0.05). The main sources of sexual and reproductive health knowledge of the respondents were television / radio / books / magazines / newspapers, schools, peers and the internet. Multivariate analysis showed that the awareness of reproductive health among male and female subjects was related to whether they acquired sexual and reproductive health knowledge from specialized agencies / communities / work units.
