Overview. Peyronie's (pay-roe-NEEZ) disease is the development of fibrous scar tissue inside the penis that causes curved, painful erections.
In Peyronie's disease, scar tissue makes the penis bend or curve during an erection. When a guy gets an erection, chambers on the side of the penis fill with blood. But with Peyronie’s, scar tissue (also called plaque) on the sheath keeps your penis from standing straight.
Many men have a slight curve in the penis. As long as there is no pain or problem with sexual performance, men with a slightly curved penis should not be concerned. In Peyronie's disease, inflammation and scar tissue form along the shaft of the penis.
