Abstract:
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, hypertension, 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.
