Ischemia after only 4 to 6 hours can lead to fibrosis and possible permanent erectile dysfunction. It can be due to sickle cell disease, medications, or illicit drugs. High-flow priapism is often due to a traumatic arteriocavernosal fistula and, although alarming, has a low risk for ischemia due to the preservation of oxygenated blood flow to the penis.
