The signs of ED are varied and may differ from one man to another.
The condition is very common. Although most often seen in men over the age of 40, ED can affect men of all ages. According to the Massachusetts Male Aging Study, which was the largest-ever survey of male erectile dysfunction, is even more common than once thought.
52% of all men between the ages of 40 and 70 have some degree of erectile dysfunction (classified as mild, moderate or severe).
