Definition
By Mayo Clinic staffPriapism is a prolonged erection of the penis. The unwanted, persistent erection isn't caused by sexual stimulation or arousal, and priapism is usually painful.
Priapism is an uncommon condition that needs immediate medical attention. 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 boys between ages 5 and 10 years old and in men from ages 20 to 50 years.
