Some parents decide to have their infants circumcised for cleanliness or religious reasons.
It used to be a routine procedure done to most newborn males. Today doctors will not usually perform it without your request unless it is medically necessary. At birth, a baby's foreskin and the glans are attached and it may take months or even years for the two to separate. Trying to pull the uncircumcised foreskin back before it is ready can cause tiny tears in the skin. If the tissue is scarred, circumcision may be necessary later in life.
