Male cycling fans, rejoice! New research suggests cycling will not affect your sex life or impact your ability to get and sustain an erection, despite previous reports on the contrary.
In a new report in The Journal of Urology, researchers found neither recreational nor intense cycling appear to have a negative impact on men’s sexual and urinary function.
“This is the largest comparative study to date, exploring the associations of cycling, bike and road characteristics with sexual and urinary function using validated questionnaires,” explained lead investigator Benjamin Breyer, of the department of urology at the University of California, San Francisco.
“We believe the results will be encouraging for cyclists. Cycling provides tremendous cardiovascular benefits and is low impact on joints. We believe the health benefits enjoyed by cyclists who ride safely will far out weight health risks.”
Some studies have suggested cycling negatively affects erectile function, caused by the prolonged perineal pressure and micro-trauma during cycling.
However, according to the American scientists, these studies lacked the use of validated measures or comparison groups, and were limited by small sample sizes.
In this multinational study, a cross-section of three athletic groups - cyclists, swimmers, and runners - was surveyed using Facebook ads and outreach to sporting clubs for athletes.
Participants included 2,774 cyclists, 539 swimmers, and 789 runners, who completed questionnaires on various aspects of sexual health, plus urinary tract infections (UTIs), urethral strictures (a narrowing of the urethra caused by injury), genital numbness and saddle sores.
In addition to the comparisons between similar athletic activities with and without perineal pressure, the researchers examined how cycling intensity, bicycle configuration and even road conditions might impact sexual and urinary functions.
Cyclists were asked about their bike type, saddle type, saddle angle, frequency of wearing padded shorts while cycling, percent of time standing out of the saddle, handlebar height and the type of surface on which they usually ride.
Cyclists were then divided into a high intensity group (cycling more than two years more than three times per week and averaging more than 25 miles per day) and a low intensity group meeting none of these criteria. Non-cyclists were defined as those who swim and/or run but do not cycle on a regular basis.
In general, when compared to swimmers and runners, cyclists’ sexual and urinary health was similar, although some cyclists were more prone to urethral strictures.
Interestingly, high intensity cyclists had overall better erectile function scores than low intensity cyclists. Neither bicycle nor road characteristics appeared to have a negative impact on cyclists.
Standing more than 20% of the time while cycling significantly reduced the odds of genital numbness. Adjusting handlebar height lower than the saddle height did increase the likelihood of genital numbness and saddle sores.
“The comparison across athletes sampled in a similar way with validated instruments is what this study adds to the literature,” said Dr Breyer.
“We’re looking more closely at those who reported numbness to see if this is a predictor for future problems.”
