Erectile Dysfunction is not a disease but a symptom of many other health problems. It is sometimes called impotence and is a condition in which a man experiences his inability to get and keep erections firm enough for sexual activity. Sometimes having an issue with an erection does not necessarily mean erectile dysfunction. Still, when it becomes persistent, it is a cause for concern.
It is one of the most common sexual problems in men, and with advancing age, it has become more common. A combination of physical and psychological factors is usually responsible for the inability to keep or get an erection. Sexual arousal is a complex process and involves emotions, blood vessels, the brain, hormones, and muscles. Problems with any of these could lead to the development of erectile dysfunction.
