Circumcision is the removal of the foreskin from the human penis. In the most common procedure, the foreskin is opened, adhesions are removed, and the foreskin is separated from the glans. After that, a circumcision device may be placed, and then the foreskin is cut off. Topical or locally injected anesthesia is used to reduce pain and physiologic stress. The procedure is most often an elective surgery performed on babies and children for religious or cultural reasons. Medically, circumcision is a treatment option for problematic cases of phimosis and balanoposthitis that do not resolve with other treatments, and for chronic urinary tract infections (UTIs).
