Does Bicycle Riding Impact the Development of Lower Urinary Tract Symptoms and Sexual Dysfunction in Men?

PURPOSE This study was designed to determine whether men who engaged in recreational bicycle riding are more likely to be affected by lower urinary tract symptoms (LUTS) and sexual dysfunction than are man who exercised by amateur marathon running with less perineal impact. MATERIALS AND METHODS A total of 22 healthy male amateur bicyclists and 17 healthy male amateur marathoners were enrolled in the study. We evaluated questionnaires including the International Prostate Symptom Score (IPSS) and the International Index of Erectile Function (IIEF), serum prostate-specific antigen (PSA), uroflowmetric values, postvoid residual (PVR) urine volume, and transrectal ultrasound of the prostate in all subjects. We also compared the prevalence of urination disorders (UD) and erectile dysfunction (ED). RESULTS There were no significant differences between the two groups in age, body mass index, comorbidities, or exercise habits (p>0.05). Mean total and subscale scores of the IPSS and IIEF and the prevalence of UD (8/22 vs. 4/17, p=0.494) and ED (11/22 vs. 10/17, p=0.748) were not significantly different between the two groups. Also, there were no significant differences between the two groups in uroflowmetric parameters such as peak urinary flow rates, voided urine volume, PVR urine volume, prostate volume, or serum PSA level. CONCLUSIONS Bicycle riding seems to have no measurable hazardous effect on voiding function or sexual function in men who cycled recreationally.
