− | 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. | + | A penile erection is the hydraulic [[effect]] of [[blood]] entering and being retained in sponge-like bodies within the [https://en.wikipedia.org/wiki/Penis penis].

| [[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. | | [[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.

− | 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. | + | 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 [https://en.wikipedia.org/wiki/PDE5_inhibitor PDE5 inhibitor drugs] (the first of which was sildenafil or Viagra).
