Circumcision is the surgical removal of the foreskin of the penis (the fold of skin that covers the tip of the penis dle). It involves cutting a portion of the foreskin covering the glans, leaving it permanently exposed. In the case of adults, it is usually performed for medical reasons, primarily as a treatment for phimosis and paraphimosis. Although there are cases of adult circumcision on religious grounds. The treatment can be performed with a dorsal incision technique where the specialist makes a small cut in the top of the foreskin. Another option is to cover technique by which a line is carried around the base of the foreskin that serve as a guide for the incision.
