Circumcision

The neonatal circumcision rate in Finland is zero. The rate of circumcision later in life is 1 in 16667. . This puts an upper bound on the number of medically necessary circumcisions at 0.006%  There is no reason to be believe that Finnish men are less susceptible to foreskin related problems than other men (not even environmental temperatures) so we may reasonable conclude that no more than 0.006% of men will need a circumcision in their life if their foreskin is not removed without their consent.
