In the most common procedure, the foreskin is opened, natural adhesions are removed in the case of infants and young children, and the foreskin is separated from the glans. After that, a circumcision device may be placed, and then the foreskin is cut off. The frenulum, which is highly sensitive, is often partially or fully removed in circumcision. The surgery is often performed without pain medication. It is important to note that the foreskin does not naturally retract from the head of the penis until around 6 years of age up to the onset of puberty and sometimes after. This makes opening the foreskin and removal of adhesions more invasive.
Three common methods of circumcision are the Gomco clamp, the Plastibell device, and the Mogen clamp. All three pinch the foreskin to cut off circulation and prevent bleeding while the doctor cuts the foreskin. The surgery lasts 15-30 minutes. Specifically, the Gomco Clamps works by inserting a a hollow bell portion on top of the exposed glans. The foreskin is rolled over the bell, and is severed by clamping it between the exterior portion of the device and the bell beneath the foreskin.
