Dr. Brian Morris, Professor of Molecular Medical Sciences. “Here are the Main Benefits of Circumcision”. Opposing Views – It reduces by 3-fold the risk of inflammation and infection of the skin of the penis. One in 10 uncircumcised men get inflammation of the head of the penis (which is covered by the foreskin). This rises to 1 in 3 if the uncircumcised man is diabetic. (Diabetic men also have other severe problems.) In contrast only 2% of circumcised men get this condition.
