Study: Riding motorcycles may cause impotence

Japanese survey reveals 70% of male bikers have trouble getting 'wood' - and we don't mean for the campfire

TROUBLE GETTING one up? A study has revealed men that ride motorcycles are at risk of impotence and urinary problems because the vibration of the engine damages nerves in their penises.

According to the Canberra Times, one of Australia's leading newspapers, a survey of more than 230 motorcyclists who rode their bikes for about three hours every weekend found almost 70 per cent had problems gaining an erection or emptying their bladders.

The study was carried out by doctors in Japan and found most motorcycle seats put undue pressure on the perineum, that unknown area between the anus and the scrotum. The pressure can restrict blood flow to the rider's todger, which in turn causes problems when asked to stand to attention. The study also revealed vibrations from the engine caused a decrease in two growth hormones in the bladder and prostate related to bladder relaxation.

Smoking and alcohol are also known causes of impotence, which coupled with today's findings, makes the late Barry Sheene's antics even more admirable.
