I can well believe we're at higher risk. The main reason I switched from my previous bike was that the twin cylinder machine was trying to purée my nads.
Even after an hour on the Fazer my groin feels slightly numb from the vibration and saddle pressure. The sensation passes after 10 minutes and there hasn't (yet) been any permanent problem, however I only average an hour a day on the bike, those who ride for a living may have noticed more symptoms.
