Peyronies disease causes the penis to bend.

Peyronie's disease isn't a disease, but a condition that affects the penis. A plaque or hard lump forms on the upper or lower side of the penis in the layers of erectile tissue. The plaque may begin as inflammation (redness and swelling) and harden into a scar. It is not cancerous. Researchers aren't sure what causes the plaque to form. Some have suggested it comes from injuring the penis by hitting it or bending it, especially during intercourse, but this doesn't explain why most cases develop slowly or why many cases go away on their own.
