Men are more prone to suffer urethral stricture if they cycle a lot.
Male cyclist health issues
A recent report suggested that the sport could have a detrimental effect on men including erectile dysfunction, however, now it appears that they were no more prone than runners and swimmers, research from the University of California-San Francisco found
The study, which was published in the Journal of Urology, asked question about urinary tract infections, numbness and sores.
Dr Benjamin Breyer, co-author of the study, found that cyclists didn't have it any worse than other fitness maniacs.
He wrote in the paper: ''Cyclists had no worse sexual or urinary functions than swimmers or runners but cyclists were more prone to urethral stricture.''
However, Benjamin did suggest that they were more prone to the thinning of the urethra and suggest cyclist should consider seat designs to put less pressure on the perineum.
