A survey questionnaire was prepared,and students voluntarily and anonymously filled it out for statistical analysis. Results The correct recognition rate of AIDS was the highest（96.11%）,while genital chlamydial infections was the lowest（29.13%）,and there was a statistically significant difference in correct recognition scores of STD between different grades and places of origin（both P<0.05）. The knowledge demand for STD prevention measures was the highest（41.12%）,20.61% of students believed that acquiring STD knowledge was difficult,regular health education was the most effective way to acquire relevant knowledge（26.90%）. 40.97% of students had a strong willingness to actively acquire knowledge,and 36.92% of students had a high willingness to offer relevant courses in school,and there had statistical differences between different grades（χ²=8.712,H=8.952, both P<0.05）. The proportions of female students who considered the family had higher necessity and importance of gender knowledge education were 61.65% and 64.24%,respectively,which were significantly higher than male students（53.46% and 55.30%）（χ²=3.981,4.831,both P<0.05）.
