Circumcision is the surgical removal of the skin covering the tip of the penis. The procedure is fairly common for newborn boys in certain parts of the world, including the United States. Circumcision after the newborn period is possible, but it's a more complex procedure.
For some families, circumcision is a religious ritual. The procedure can also be a matter of family tradition, personal hygiene or preventive health care. For others, however, circumcision seems unnecessary or disfiguring.
