Ischemic priapism can cause serious complications. The blood trapped in the penis is deprived of oxygen. When an erection lasts for longer than four hours, this oxygen-poor blood can begin to damage or destroy tissues in the penis. As a result, untreated priapism may cause:

  • Erectile dysfunction, the inability of the penis to become or stay erect with sexual arousal
  • Disfigurement of the penis
