主 题：frequency intercourse erectile dysfunction outpatients cross-sectional study
摘 要：This study was aimed to investigate the influence of coital frequency and masturbation on erectile dysfunction （ED） in Chinese patients. A total of 332 male outpatients with or without ED and volunteers were recruited from Zhongnan Hospital, Wuhan University, China. ED was assessed by using the five-item International Index of Erectile Function scale and the frequency of intercourse by patients＇ self-report. After adjusting for lifestyle factors and diseases-related factors, the analyses showed that coital and masturbation in a certain frequency tended to decrease the risk of ED. Men reporting intercourse once a week had lower risk of ED than those did less than once a week, with age, hyperlipidemia, hy-pertension, diabetes, body mass index, smoking, and drinking as covariates （P=0.67, adjusted odds ratio [OR] = 0.84; 95% confidence interval [CI]： 0.37-1.88）. For those reporting coital frequency two times per week and three or more times per week, there were 63% （adjusted OR = 0.37; 95% CI： 0.18-0.77） and 85% （adjusted OR = 0.15; 95% CI： 0.07-0.35） lower risk of ED than those reporting intercourse frequency less than once per week, respectively （P〈0.05）. Results indicated that maintaining a regular frequency of intercourse can reduce the risk of ED for males aged among 30 to 75 years.
