Impotence is the inability of a man either to have an erection or to keep the penis erect long enough to have sexual intercourse.
This is a common problem affecting as many as 10 million men in the United States alone. By the time most men are 40 they have already experienced impotence at some time in their lives.
When just a single incident occurs, the best thing to do is forget about it. Problems arise when this difficulty starts occurring regularly.
Men afflicted with repeated impotence tend to be middle-aged and older, with such a condition most common in men 60 years of age and older. Regardless of the age, however, many men who have this problem can be treated successfully.
Impotence can result from a wide variety of problems. For example, cardiovascular problems, diabetes, injuries to the spinal column, and side effects from high blood pressure medicine are among the physical conditions that can lead to impotence.
An erection occurs when the nervous system activates a rapid increase in blood flow.
The vascular muscle in the spongy area becomes engorged with blood and outflow of blood is cut off.
Erection can be elicited by the so-called reflex erection as we see in spinal cord patients, or can be caused by psychogenic stimulation. In order to get an erection, the blood flow must increase and, at the same time, the blood has to be prevented from leaving the penis.
With regular penis exercising, you can help to increase the bloodflow to the penis and this can be helpful in some cases of impotency.
