Erectile dysfunction (ED), in other words, the lack of potency, which can be characterized as inability to achieve or sustain an erection for satisfactory sexual activity. ED  stays apart from other conditions that interfere with male sexual intercourse, such as lack of sexual desire and problems with ejaculation and achieving orgasm.

Erectile dysfunction can have different forms: it can be mild, moderate or severe. The last form is when men have a total inability to achieve an erection. People with moderate ED have an inconsistent ability to achieve an erection. Mild form of ED is the easiest to treat and can be associated with taking certain medications or having conditions interfering with normal erectile process.

Estimating ED frequency is extremely difficult and hardly possible to find out the real number of men suffering from this disorder.  The reason is that men fear to discuss erectile dysfunction with their doctors due to embarrassment. That is why experts can’t say for sure how many men erectile dysfunction affects.

ED problems can occur at any age, but it is uncommon among young men (younger than 40) and more common in the elderly. With age most men experience problems with potency more often.

According to recent study which associated ED with aging, ED increases from 5% among men 40 years of age to 15% among men 70 years and older. Erectile dysfunction occurs in 20% of men between ages 50-54, and in 50% of men between ages 70-78. As for the severity of ED, studies have noted that 35% of men 40-70 years of age suffer from moderate to severe ED, and an additional 15% may have milder forms.
