Study links mountain biking to male infertility

Dec. 2, 2002 10:00 AM

CHICAGO - Men who log 3,000 miles or more a year on their mountain bikes suffer scrotal damage that could reduce their fertility, according to a study released on Monday.

The report, based on examinations of 40 ''extreme'' bikers and 35 non- cyclists, suggests that men who spend the most time on their bikes should invest in shock absorbers and suspension systems that could double the cost of a standard mountain bike, the study said.

Scrotal examinations of the bikers found that 88 percent had cysts, calcification, varicose veins and other abnormalities compared to 26 percent of the non-biking group.

Sperm samples showed that the extreme bikers had a count that was only a third that of the non-cyclists while bikers' sperm had less motility or movement than non-bikers.

''We believe that extreme mountain biking results in semen alteration, which may have an impact on fertility,'' said lead author Ferdinand Frauscher of University Hospital in Innsbruck, Austria.

''We believe that repeated mechanical trauma to the testicles results in some degree of vascular damage and may thereby cause a reduction in sperm motility,'' he said.

His report was released at the annual meeting of the Radiological Society of North America

Men who are dedicated mountain bikers may be risking their fertility if they fail to equip the bikes with protective gear, researchers report.

Nearly 90 percent of the bikers studied had lower sperm counts and sperm that was less mobile, compared with a group that did not ride the bikes, the study said.

The report was presented by Dr. Ferdinand Frauscher, a uroradiologist at University Hospital in Innsbruck, Austria, at a conference of the Radiological Society of North America.

The researchers were following up on an earlier study that found scrotum irregularities among avid mountain bikers.

For this study, the researchers looked at 40 men ages 18 to 44 who rode for more than 2 hours a day, 6 days a week.

On average, the study found, the bikers produced only a third the amount of sperm as those who were not bike riders. The researchers suggest that trauma to the testicles causes vascular damage affecting the sperm.

In an interview, Dr. Frauscher, a mountain biker himself, said that much of the damage could be prevented if the bikers outfitted their bikes with wider, padded seats and shock absorbers.

But some riders are reluctant to invest in the additions, which can double the cost of the bike and add burdensome weight.

Rack, Nutcrack, and other ball smashing possibilities

Maybe it because all of those bikers wear tight pants and are repeatedly experiencing the dreaded, nut-crush syndrome
