(HealthDay News) — Compared with swimmers/runners, cyclists have no worse sexual or urinary functions, according to a study published in The Journal of Urology.
Mohannad A. Awad, MD, from the University of California-San Francisco, and colleagues queried cyclists and a comparison group of swimmers and runners using validated questionnaires including the Sexual Health Inventory for Men (SHIM), International Prostate Symptom Score (I-PSS), and National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI). Data were obtained for 3932 survey respondents.
The researchers found that, compared with low- and high-intensity cyclists, swimmers/runners had a lower mean SHIM score (19.5 vs 19.9 and 20.7; P=0.02 and P<0.001, respectively). There were no significant differences in I-PSS or NIH-CPSI scores or in history of urinary tract infection. Compared with swimmers/runners, cyclists had statistically higher odds of urethral stricture (odds ratio, 2.5; P=0.042). The odds of genital numbness were reduced with standing more than 20% of the time while cycling (odds ratio, 0.4; P=0.006). The odds of genital numbness and saddle sores were reduced with adjusting the handlebar higher (odds ratio, 0.8; P=0.005) or even with the saddle (odds ratio, 0.6; P<0.001).
“Cyclists had no worse sexual or urinary functions than swimmers or runners but cyclists were more prone to urethral stricture,” the authors write.
