Persistent, painful erection of the penis without sexual arousal. Priapism occurs when blood does not drain from the spongy tissue of the penis, thus keeping the penis erect. This may be caused by clotting in the blood vessels due to a blood disorder or as a result of treatment for impotence. Urgent treatment is needed in order to avoid permanent damage. The treatment may involve withdrawal of blood from the penis with a needle.
