Definition of Dysfunction

Dysfunction: Difficult function or abnormal function.

There is, for example:

• Constitutional hepatic dysfunction, (familial nonhemolytic jaundice),
• Dental dysfunction (abnormal functioning of dental structures),
• Minimal brain dysfunction (attention deficit disorder),
• Placental dysfunction (dysmature placenta),
• Psychosexual dysfunction, and
• Sexual dysfunction (a disturbance of sexual functioning).

Erectile dysfunction has become a common term thanks to the advent (and advertising) of Viagra. Erectile dysfunction is a consistent inability to sustain an erection sufficient for sexual intercourse.
