There is no scientific need to circumcise male babies, and the procedure is becoming less common in the United States. Most Jewish and Islamic parents circumcise their sons for religious reasons.
As of 2009, approximately a third of American boys undergo circumcision. The American Academy of Pediatrics neither encourages nor discourages circumcision, but recommends that parents learn more before making the decision for their children. Some adults with inflammation or constriction of the foreskin may require circumcision. As of 2015, the majority of men in Asia, Europe, and South and Central America do not receive circumcision, while the Canadian Paediatric Society recommends against circumcision for medical and ethical reasons.
