Priapism is a prolonged erection of the penis. The persistent erection continues hours beyond or isn't caused by sexual stimulation. Priapism is usually painful.
Although priapism is an uncommon condition overall, it occurs commonly in certain groups, such as people who have sickle cell anemia. Prompt treatment for priapism is usually needed to prevent tissue damage that could result in the inability to get or maintain an erection (erectile dysfunction).
Priapism is most common in men in their 30s.
