title: Erectile dysfunction: a multifaceted disorder.
abstract: The cause may be vascular, neurogenic, hormonal, drug-related, psychogenic, or a combination thereof. In older men in particular, underlying causes may include life-threatening disorders. Evaluation requires directed questioning, since men often fail to volunteer important related symptoms. Clinical findings guide laboratory testing and treatment is tailored to the etiology.
