Erectile dysfunction (ED, "male '''impotence'''") is [[sexual]] dysfunction characterized by the inability to [[develop]] or maintain an [http://en.wikipedia.org/wiki/Erection erection] of the penis during sexual [[performance]].

A penile erection is the hydraulic [[effect]] of [[blood]] entering and being retained in sponge-like bodies within the [http://en.wikipedia.org/wiki/Penis penis]. The [[process]] is often initiated as a result of [http://en.wikipedia.org/wiki/Sexual_arousal sexual arousal], when signals are transmitted from the [[brain]] to nerves in the penis. Erectile dysfunction is indicated when an erection is [[difficult]] to produce. There are various circulatory causes, including alteration of the [http://en.wikipedia.org/wiki/Voltage-gated_potassium_channel voltage-gated potassium channel], as in arsenic poisoning from drinking water. The most important organic causes are [http://en.wikipedia.org/wiki/Cardiovascular cardiovascular] disease and [http://en.wikipedia.org/wiki/Diabetes_mellitus diabetes], neurological problems (for example, trauma from prostatectomy surgery), [http://en.wikipedia.org/wiki/Hormones hormonal] insufficiencies (hypogonadism) and drug side effects.

[[Psychological]] impotence is where erection or penetration fails due to [[thoughts]] or [[feelings]] (psychological reasons) rather than [[physical]] impossibility; this is somewhat less frequent but often can be helped. Notably in psychological impotence, there is a strong [[response]] to placebo treatment. Erectile dysfunction, tied closely as it is about [[ideas]] of [[physical]] well being, can have severe [[psychological]] consequences.

Besides treating the underlying causes such as potassium deficiency or arsenic contamination of drinking water, the first line treatment of erectile dysfunction consists of a trial of [http://en.wikipedia.org/wiki/PDE5_inhibitor PDE5 inhibitor drugs] (the first of which was sildenafil or Viagra). In some cases, treatment can involve prostaglandin tablets in the urethra, injections into the penis, a penile prosthesis, a penis pump or vascular reconstructive surgery.

The [[Latin]] term ''impotentia coeundi'' describes simple inability to insert the penis into the [http://en.wikipedia.org/wiki/Vagina vagina]. It is now mostly replaced by more precise terms. The study of erectile dysfunction within [[medicine]] is covered by [http://en.wikipedia.org/wiki/Andrology andrology], a sub-field within [http://en.wikipedia.org/wiki/Urology urology].
