Objective To better understand the knowledge, attitude, practice status of sexual dysfunction (SD) in medical staffs in field of reproductive health in Tianjin. Methods Using random, stratified and clustered sampling ap-proach, we selected 507 medical staffs in field of reproductive healthcare in Tianjin. Self-administered questionnaire on sex-ual dysfunction KAP was employed to survey the general condition, to understand SD knowledge and their attitude to SD, to perceive SD prevalence of the medical staffs and their demand to sexual dysfunction training. Results The people who re-spond to our survey had high awareness to SD, but they are lack of knowlege in mechanism on sexual behavior and female SD related knowledge. Multiple-factor analysis indicated that young age group respondants(β=-0.827,P=0.018)and medical staffs from high-tier medical institutions (β=-0.223, P=0.048) showed higher awareness. When they suffered SD, 49.28%re-spondants would see doctor immediately, 36.85% informants chosen temporary observation, and 9.73% informants shown negative altitude. Minority (17.14%) of medical staff are able to confirmed SD to themselves and 90.48% of medical staff de-mand training on SD related knowledge. Conclusion It’s necessary to perform continuing education to medical staffs via different intervention, so as to improve their cognitive level and attitude to SD, and these can help them providing better ser-vice to their patients and the public.
