Infant boys are born with a non-retractable [[foreskin]]. The '''development of retractable foreskin''' occurs gradually over a widely-variable number of years. In the majority of adult men, the [[foreskin]] normally retracts to reveal the [[glans penis| head of the penis]]. In newborns, it is common normal for the foreskin to be fused to the head of the penis by the [[synechia]], thus rendering it non-retractable. The [[preputial sac]] is sealed by the [[synechia]].<ref name="fleiss-hodges-vanhowe1998">{{TaylorJR LockwoodAP TaylorAJ 1996}}</ref> The [[foreskin ]] usually separates from the glans and becomes retractable with increasing age. There is much uncertainty among health care workers about when the foreskin of a boy should become retractable.<ref>{{REFjournal

}}</ref> The mistaken belief that the foreskin was supposed to be retractable at the time of birth of the infant has led to a characterization of the genitalia of most infant males as defective at birth. This has led to many false diagnoses of [[phimosis]], followed by unnecessary [[circumcision]], when, in fact, the [[foreskin ]] is developmentally normal. There is no one correct age for the foreskin to become retractable.

Normally, developmental non-retractability does not cause any problems, in fact, it is protective of the [[glans penis]] and protects against [[meatal stenosis]]. Non-retractability may be deemed pathological if it causes problems, such as difficulty urinating or performing normal sexual functions, but even then, this is rare, and, if the non-retractability itself is not caused by pathological inflammation, it cannot be called "pathological" or "true phimosis." A foreskin that is so narrow it will retract very little or not at all, but is not the result of a pathological inflammation, is accurately termed ''preputial stenosis'' (narrow prepuce), and will respond to treatment including steroid creams, manual [[stretching]], and changing [[masturbation]] habits.

The first data on development of retractile foreskin were provided in 1949 by the famous British paediatrician, [[Douglas Gairdner]].<ref name="Gairdner">{{REFjournal |last=Gairdner |first=D. |author-link=Douglas Gairdner |title=The fate of the foreskin: a study of circumcision |journal=Br Med J |volume=2 |issue= |pages=1433-7 |url=https://europepmc.org/backend/ptpmcrender.fcgi?accid=PMC2051968&blobtype=pdf |quote= |pubmedID=15408299 |pubmedCID=2051968 |DOI=10.1136/bmj.2.4642.1433 |date=GairdnerDM 1949 |accessdate=}}</ref> His data have been incorporated into many textbooks and is still being repeated in the medical literature today. [[Douglas Gairdner|Gairdner]] said that 80 percent of boys should have a retractable foreskin by the age of two years, and 90 percent of boys should have a retractable prepuce by the age of three years.<ref name="Gairdner"/>

Almost all boys are born with the inner [[foreskin ]] mucosa fused with the underlying [[glans penis]] by the [[synechia]]. Most also have a narrow [[foreskin ]] that cannot retract. Non-retractile foreskin is normal at birth and remains common in the normal range until after puberty (age 18). 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.

The first two reasons are normal in childhood and are not pathological in children. The third can be treated conservatively, retaining the [[foreskin]].

Boys usually are born with a non-retractile foreskin. 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 in childhood and 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

Care-givers and healthcare providers must be careful to avoid [[forced retraction|premature retraction]] of the foreskin, which is contrary to medical recommendations, painful, traumatic, tears the attachment points (synechiae), may cause [[infection]], is likely to generate medico-legal problemsissues, and may cause [[paraphimosis]], with the tight foreskin acting like a tourniquet. The first person to retract the boy’s [[foreskin ]] should be the boy himself.<ref name="Wright1994"/> <ref>{{REFweb

See [[Phimosis]] for more information. ===Fixing a fused foreskin=== 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. Apply petroleum jelly after separation occurs for about two weeks to prevent re-adhesion.  If one is unsuccessful, then one may need to consult a urologist. ===Issues with circumcision as treatment=== [[Adolescent and adult circumcision| Male circumcision ]] is outmoded as a treatment for non-retractile foreskin, but it is still recommended by many [[Issues with American urologists and the practice of male circumcision| urologists ]] because of lack of adequate information, and perhaps because of the [[Financial Incentive|profit to the doctor]] associated with circumcision. Nevertheless, [[Adolescent and adult circumcision | circumcision]] should be avoided whenever possible because of [[pain]], [[trauma]], cost,<ref name="Van Howe">{{REFjournal

}}</ref>and adverse [[Sexual effects of circumcision| sexual]] and [[Psychological issues of male circumcision| psychological]] effects. ==Adult foreskin=====Should the foreskin retract automatically when the penis becomes erect?===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. A very few of the longest foreskins will not stay retracted when manually retracted. Instead, they will spontaneously [[gliding action| glide]] forward when released. This condition is believed to be very rare.
