Erectile dysfunction (ED) affects the lives of many middle-aged men and their partners to one degree or another. The term erectile dysfunction covers a range of disorders, but usually refers to the inability to obtain an adequate erection for satisfactory sexual activity.

Although erectile dysfunction, formerly called impotence, is more common in men older than 65, it can occur at any age. An occasional episode of erectile dysfunction happens to most men and is normal. As men age, it's also normal to experience changes in erectile function. Erections may take longer to develop, may not be as rigid or may require more direct stimulation to be achieved. Men may also notice that orgasms are less intense, the volume of ejaculate is reduced and recovery time increases between erections.

When erectile dysfunction proves to be a pattern or a persistent problem, it can interfere with a man's self-image as well as his and his partner's sexual life. Erectile dysfunction may also be a sign of a physical or emotional problem that requires treatment.

Erectile dysfunction was once a taboo subject, but more men are seeking help. Doctors are gaining a better understanding of what causes erectile dysfunction and are finding new and better treatments.
