Currently riding SMP saddles on my single and tandem, however...
ED can be caused by excessive smoking, diabetes, and a number of other causes that go along with a compromised cardio vascular system. If you were to do a study on whether there was a connection between ED and heart disease, I'm sure you could end up with more couch potato smokers than high mileage cyclists.
I'm still sticking with my SMP saddles.
