Peyronie's disease. Peyronie's disease or Peyronie disease (/peÉªroÊËniË/), also known as induratio penis plastica (IPP) or chronic inflammation of the tunica albuginea (CITA), is a connective tissue disorder involving the growth of fibrous plaques in the soft tissue of the penis affecting an estimated 5% of men.
What Causes Peyronie's Disease? The cause of Peyronie's is not fully understood, but it may result from damage to the penis. The penis has a sponge-like tube (corpus cavernosum) on each side that consists of small blood vessels. When a man is aroused, blood flows through the corpus cavernosa and causes the penis to stretch and stiffen.
