What is Peyronie’s Disease?
Peyronie’s (pay-roe-NEEZ) disease is the development of fibrous scar tissue inside the penis that causes curved, painful erections. Penises vary in shape and size, and having a curved erection isn’t necessarily a cause for concern. But Peyronie’s disease causes a significant bend or pain in some men.
This can prevent you from having sex or might make it difficult to get or maintain an erection (erectile dysfunction). For many men, Peyronie’s disease also causes stress and anxiety.
Peyronie’s disease sometimes goes away on its own. But in most cases, it will remain stable or worsen. Treatment might be needed if the curvature is severe enough that it prevents successful sexual intercourse.
Peyronie’s disease signs and symptoms might appear suddenly or develop gradually. The most common signs and symptoms include:
- Scar tissue. The scar tissue (plaques) associated with Peyronie’s disease can be felt under the skin of the penis as flat lumps or a band of hard tissue.
- A significant bend to the penis. Your penis might be curved upward, downward or bent to one side. In some cases, the erect penis might have narrowing, indentations or an hourglass appearance, with a tight, narrow band around the shaft.
- Erection problems. Peyronie’s disease might cause problems getting or maintaining an erection (erectile dysfunction).
- Shortening of the penis. Your penis might become shorter as a result of Peyronie’s disease.
- Pain. You might have penile pain, with or without an erection.
The cause of Peyronie’s disease isn’t completely understood, but a number of factors appear to be involved.
It’s thought Peyronie’s disease generally results from repeated injury to the penis. For example, the penis might be damaged during sex, athletic activity or as the result of an accident. However, most often, no specific trauma to the penis is recalled.
During the healing process, scar tissue forms in a disorganized manner, which might then lead to a nodule that you can feel or development of curvature.
Each side of the penis contains a sponge-like tube (corpus cavernosum) that contains many tiny blood vessels. Each of the corpora cavernosa is encased in a sheath of elastic tissue called the tunica albuginea (TOO-nih-kuh al-BYOO-JIN-e-uh), which stretches during an erection.
When you become sexually aroused, blood flow to these chambers increases. As the chambers fill with blood, the penis expands, straightens and stiffens into an erection.
