Erectile Dysfunction (ED)

Erectile Dysfunction (ED) is defined as "the inability of the male to achieve an erect penis as part of the overall multifaceted process of male sexual function." In the past, ED was regarded as the inability to get and/or keep an erection for satisfactory sexual intercourse. The current definition de-emphasizes intercourse as the main aspect of sexual life and gives equal importance to other aspects of male sexual behavior.

ED can become present in most men somewhere between the ages of 35 and 65.
