Peyronie’s Disease | Causes & Risk Factors


What causes Peyronie's disease?

Scar tissue under the skin of the penis causes the curve. No one knows why the scar tissue starts. Some men who have Peyronie's disease have had a penis injury that causes scar tissue. The scar tissue feels like a ridge or a row of tiny bumps. The scar tissue can keep getting worse during the first few years, making the penis curve more and more. You might notice this more during an erection. After a few years, the scar tissue usually stops getting worse, but it doesn't go away.
