Erectile dysfunction, formerly called impotence, is the inability to obtain an adequate erection for satisfactory sexual activity. It’s more common in men over 50years, but it can occur at any age.
Erectile dysfunction (ED, “male impotence”) is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis sufficient for satisfactory sexual performance. An erection occurs as a hydraulic effect due to blood entering and being retained in sponge-like bodies within the penis.
The process is most often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the pelvis. Erectile dysfunction is indicated when an erection is consistently difficult or impossible to produce.
