Changes

Almost all boys are born with the inner [[foreskin]] mucosa fused with the underlying [[glans penis]] by the [[synechia]].<ref name="agarwal2005" /> Most also have a narrow [[foreskin]] that cannot retract. Non-retractile foreskin is normal at birth and remains in the normal range until after [[puberty ]] (age 18).<ref name="agarwal2005" /> The non-retractile [[foreskin]] is nature's way of protecting the young boy from [[meatal stenosis]] and [[infection]] in the [[preputial sac]].

Some boys develop retractile foreskin earlier, and about 2 -4 percent of males have a non-retractile foreskin throughout life. Non-retractile foreskin is not a disease and does not require treatment.
