What about men's testicular/prostate health though? Bike seats are specially designed for cycling ergonomics; desk chairs are design for sitting upright in an ergonomic _stationary_ position.

I say this because I had some prostate bruising (I recovered from that quickly doing yoga), but I attribute it to sitting too long; I don't even want to think what a pedaling motion in my chair would do down there! Granted, I have never pedaled in my chair so I accept that maybe it is fine—I'm just not willing to take the risk.

Personally, I'd go more for a walking desk or something where the motion is natural, but the desired cardio effect is the same.

I haven't experienced, nor done anything to avoid, any sort of pain or injury like this. Maybe I'm just lucky?
