Undergraduates, generally 18-24 years old, are in the most active period of sexual lives. With the development of economy and Internet, students have more ways to access to sexual information, some of which are wrong. To characterize the differences and similarities among college students about their contraceptive knowledge and attitude towards sex education,anonymous questionnaire forms were sent out to undergraduates from College of Liberal Arts, Yunnan University. With the help of SO JUMP, the overall sample was randomly chosen and consisted of four grades in undergraduates. In order to analyze the gender differences in the research topics, the respondents were divided into two groups based on gender. Last, three conclusions were drawn:firstly, misleading knowledge of contraception was found in undergraduates; next, males have better contraceptive knowledge than female students; finally, not only should universities and colleges spread correct reproductive knowledge among students, but also society as a whole should popularize safe sexual practices.
