Peyronie's disease (PD) is a benign, acquired penile connective tissue disease characterized by the occurrence of fibrotic plaques within the tunica albuginea —the dense elastic covering of the corpora cavernosa. Peyronie’s disease is a connective tissue disorder of the penis that can be likened to Dupuytren’s contracture of the hand. It is characterized by the triad of bent erections, pain in the penis with erections and palpable penile plaque. Peyronie's disease occurs when a buildup of scar tissue causes curved and often painful erections. Learn the symptoms, causes, and treatment options. Peyronie's disease is a condition in which scar tissue in the penis causes the penis to bend. WebMD looks at its causes, symptoms, and treatment. Learn about Peyronie’s disease, the causes, how it develops, the risk factors, diagnosis, and treatment options, and clinical trials. Peyronie's (pay-roe-NEEZ) disease is a condition in which fibrous scar tissue forms in the deeper tissues under the skin of the penis. This causes curved, painful erections. What is Peyronie’s disease? Peyronie’s (pay-roe-NEEZ) disease is a condition in which scar tissue (plaque) in your penis causes it to bend, curve or lose length or girth (circumference). You may be able to feel the scar tissue through your skin, or you may have pain in a specific part of your penis as the scar tissue forms. If you have Peyronie's disease symptoms, you're likely to start by seeing your family doctor or general practitioner. You might be referred to a specialist in male sexual disorders called a urologist. Peyronie’s disease is a buildup of scar tissue on the penis, causing it to bend or curve during erections. This scar tissue interferes with the flexibility and stretching of the tissues in the penis, which results in a bent penis. Peyronie's disease causes your penis to curve due to plaque build-up under your skin. You can treat this condition with injections, oral medications, and, in severe cases, surgery.
