About This Condition
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.
ED is defined by the symptoms listed above. Symptoms may also include loss of sexual desire (libido), premature ejaculation, or inability to achieve orgasm.
Depending on the cause, therapy may include psychological and behavioral counseling, treatment of underlying cardiovascular disease, and avoidance of medications such as cimetidine, antihypertensives, and MAO inhibitors. Penile vacuum devices and surgical options, such as penile implants and vascular repair, are usually limited to those who have not responded to other treatments.
