Cavernous sclerosis is the development of fibrous tissue inside the penis, causing curvature and deformation during erection. The progression of cavernous sclerosis can cause significant pain in some men, even leading to self-consciousness and stress during sexual intercourse.

Penile curvature is a fairly common condition in men and can be treated. Penile curvature has different levels. If the curvature is mild and does not affect physiological function, no treatment is needed. However, in some cases, severe curvature affects sexual ability, urination ability and causes uncomfortable symptoms for the patient, requiring surgical treatment.
