Some men may have all the risk factors, obesity, high blood pressure, atherosclerosis, poor diet, smoke like a chimney and drink like a fish...and still not seem to have any problems in the bedroom. For most men however, the why is pretty evident. The very place you want them to be flexible and elastic to let the blood flow in when you become. Others seem to be in great health, exercise, pay attention to their diet and still have trouble.

They don't understand, at least not yet, why they are troubled. It can cause arteriosclerosis, or hardening/furring of the arteries. Lifestyle factors, diet, exercise, weight, smoking, alcohol, are right at the top of the list of what can get you into trouble. Not just the arteries in your head, heart or legs but in your penis as well. There's a big difference between why you have ED and what causes ED. But it would also be really annoying.

They thicken and become less elastic. It would be comforting to say some version of it's a mystery, and be done with it.

Yet, for some men, it is a mystery.
