===Foreskin in infancy and childhood===

Baby boys are born with the foreskin fused with the [[glans penis]] by the balanopreputial lamina, a [[synechia| synechial membrane]], which prevents retraction. In addition, the tip of the foreskin ([[acroposthion]]) is usually too narrow to allow [[retraction of the foreskin]]. The preputial cavity is closed by the synechia and cannot be infected.<ref name="fleiss-hodges-vanhowe1998"/>

===Foreskin in adolescence===

The foreskin is in a transitional state during puberty and adolesence in which it is changing from the non-retractile foreskin of childhood to thh fully retractable foreskin of adulthood. Many adolescents complain of a non-retractable foreskin. Many need to do manual [[stretching]]. They usually achieve full retraction by age 16.
