Development of retractable foreskin: Difference between revisions

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 percent of males have a non-retractile foreskin throughout life. Non-retractile foreskin is not a disease and does not require treatment.  

[[Jakob Øster]], a Danish physician who conducted school examinations, reported his findings on the examination of school-boys in [[Denmark]], where [[circumcision]] is rare.<ref name="Øster1968">{{OesterJ 1968}}</ref> Øster (1968) found that the incidence of fusion of the [[foreskin]] with the [[glans penis]] steadily declines with increasing age and foreskin retractability increases with age.<ref name="Øster1968"/> Kayaba et al. (1996) also investigated the development of foreskin retraction in boys from age 0 to age 15.5 Kayaba et al. also reported increasing retractability with increasing age. Kayaba et al. reported that about only 42 percent of boys aged 8-10 have fully retractile foreskin, but the percentage increases to 62.9 percent in boys aged 11-15.<ref name="kayaba1996" /> Imamura (1997) reported that 77 percent of boys aged 11-15 had retractile foreskin.<ref name="imamura1997" /> Thorvaldsen & Meyhoff (2005) conducted a survey of 4000 young men in [[Denmark]]. They reported that the mean age of first foreskin retraction is 10.4 years in [[Denmark]].<ref name="thorvaldsen2005">{{REFjournal

The findings reported by Ko et al. are consistent with the findings reported by Øster (1968), by Kayaba et al. (1996), and by Thorvaldsen & Meyhoff (2005)

Boys are born with a non-retractile foreskin.<ref name="agarwal2005" /> The [[foreskin]] gradually becomes retractable over a variable period of time ranging from birth to 18 years or more.<ref name="Øster1968"/><ref name="Thorvaldsen"/> There is no “right” age for the foreskin to become retractable. Non-retractile foreskin does not threaten health so no intervention is necessary. Many boys only develop a retractable foreskin after puberty. Education of concerned parents usually is the only action required.<ref>{{REFjournal

In a few cases, the [[Synechia| synechial]] fusion of childhood lingers past puberty. After puberty, the synechial fusion should be about ready to spontaneously release the [[foreskin]] from the [[glans penis]]. One may try gently peeling the [[foreskin]] away from the glans penis by using one's thumbs. It may take one several tries to get it all separated. Do ''not'' force anything and do ''not'' cause cause yourself pain.

The answer to this question depends on the relative length of the [[foreskin]] in relation to the length of the [[penis]]. If the foreskin is shorter than the erect penis, then it will retract automatically on [[erection]]. On the other hand, if the foreskin is longer than the erect penis, then automatic retraction will not occur. This condition is not viewed as a problem.

Many men think a longer foreskin or [[acroposthion]] is better than a shorter foreskin for both functional and esthetic reasons.
