Are most men have circumcised?

Varies: In the us circumcision is commonplace, 65-80 %, france 30%, australia 30%, great britain 10% (not covered by national health insurance). There is data suggesting increased life risks of UTI & std if not & i remember it being the most requested elective surgery among young enlisted men during my navy years. If it is done at all it is easiest and heals quickest in newborns.
