Impotence is the failure to achieve an erection, a condition faced by an increasing number of men.
In order to diagnose the potential problems that lead to this condition, it is useful to describe what conditions must be present for erection to take place. The first component you need to achieve an erection is a normal, intact male sexual organ. Secondly, a normal amount of circulating hormones is necessary. Third, a man must have an intact nerve supply and blood flow to the male sex organ. Finally, normal erections require a healthy psychological response to the arousing stimuli, coupled with a relaxed state of mind.
