That is true, but if not cleaned away regularly, bacteria and fungus are allowed to build up. Smegma itself is not unclean it is basically dead skin cells and sebum (oil). It actually protects the glans against infection on a normal penis.

There is no accurate study to prove that circumcision reduces infection. Modern science in fact dictates otherwise. It is very similar to tonsil removal, 99% of the time not required. The foreskin, like the tonsils, is actually there to act as an infection trap.
