Peyronie's Disease

Peyronie's disease is where plaques (segments of flat scar tissue) form under the skin of the penis. These plaques can cause the penis to bend or become indented during erections. The plaques can often be felt through the skin and can be painful.

Overview

The main roles of the penis are to carry urine and sperm out of the body. There are 3 tubes inside the penis. One is called the urethra. It is hollow and carries urine from the bladder through the penis to the outside. The other 2 tubes are called the corpora cavernosa. These are soft, spongy tubes that fill with blood to make the penis stiff during an erection. The 3 tubes are wrapped together by a very tough fibrous sheath called the tunica albuginea. During sex, the stiffness of the penis makes it hard enough for sex. Then the urethra acts as a channel to carry semen into the vagina.

Peyronie's disease plaques mostly (70% of the time) form on the top (or dorsal side) of the penis. The plaques make the tunica albuginea less flexible and may cause the penis to bend upwards when it stiffens. When plaques form on the bottom or side of the penis, the bend will be downward or sideways. Some men have more than one plaque, which may cause complex curves.
