Changes

When the natural protection of the [[foreskin]] for the [[glans penis]] is unavailable, the human body is noted for its ability to apply a layer of keratin to the glans penis as substitute protection. This is a late [[complication]] of [[circumcision]] and results in a partial loss of sensation in the glans penis. This process is called [[keratinization]].
