Causes of Impotence Impotence has many causes perhaps 100 or more. Any one of them can affect a man with diabetes. The most common causes of impotence in men with diabetes are physical problems like blood vessel disease and nerve disease. If you have either of these side effects of diabetes, you may have to deal with impotence at some time. But there are tests to find the cause of the problem, and there are treatments for nearly all men who want them.
Impotence is either a psychological or a physical problem.
Your doctor will try to find out which kind of problem is causing your symptoms. It may be hard to decide where the problem lies, because sex requires that the mind and body work together. Sexual desire begins in the brain and results in responses in the nervous system and blood vessels that cause an erection. The male sex hormone testosterone also plays a major role both in sexual desire and in being able to have an erection. You may be worried or stressed, so your brain is not alert to the signals of the testosterone hormone.
