Priapism

Priapism is a potentially painful medical condition in which the erect penis does not return to its flaccid state, despite the absence of both physical and psychological stimulation, within four hours. Priapism is considered a medical emergency, which should receive proper treatment by a qualified medical practitioner. There are two types of priapism: low-flow (ischemic) and high-flow (nonischemic); 80% to 90% of clinically presented priapisms are low-flow disorders. Low-flow involves the blood not adequately returning to the body from the penis. High-flow involves a short-circuit of the vascular system partway along the penis. Treatment is different for each type. Early treatment can be beneficial for a functional recovery.

Not all sources give four hours as the guideline for priapism occurring: "The duration time of a normal erection before it is classifiable as priapism is still controversial. Ongoing penile erections for more than 6 hours can be classified as priapism."

The name comes from the Greek god Priapus (Ancient Greek: Π"ίαπος), a fertility god often represented with a disproportionately large and permanent erection.
