The membrane, which is called the <i>balanopreputial lamina</i>, is common to both parts, so retraction of the boy's foreskin is prevented by nature. There is good reason for this, since the [[foreskin]] provides protection to the [[penis]] while in the diaper, which usually contains feces, urine, and ammonia. Boys with a protective foreskin do not develop [[meatal stenosis]]. | ||
The fusion of the balanopreputial lamina gradually breaks down over a widely variable period of years, so the foreskin can be retracted. Thorvaldsen & Meyhoff (2005) reported the mean age of first foreskin retraction to be 10.4 years.<ref name="thorvaldsen2005">{{REFjournal | |||
