Erectile dysfunction (ED) is the inability of a male to attain or sustain an erection sufficient for sexual intercourse.

It can be a persistent condition; however, almost half of all men experience ED only occasionally. ED can have physical, psychological, or drug-induced causes.¹ Although some doctors used to believe differently, most researchers and doctors now believe that physical factors are responsible for the majority of ED cases.

Several conditions may contribute to ED by impairing blood flow to the penis. These include atherosclerosis, diabetes, hypothyroidism, multiple sclerosis, and chronic alcohol abuse.
