BS ! The major cause of impotence is cardiovascular disease. Biking reduces this greatly. Yes, a few cases of impotence will by caused by bike seats, but on balance, biking cures impotence.
Likewise, seat belts and airbags do cause some deaths, but you'd be foolish not to use them while riding in a car.
