The Development of Retractile Foreskin
in the Child and Adolescent
in the Child and Adolescent
A guidance for healthcare providers from Doctors Opposing
Circumcision
Introduction. There
is much uncertainty among health care workers about when the foreskin of a boy
should become retractable.1 This has caused many false diagnoses of phimosis, followed
by unnecessary circumcision, when, in fact, the foreskin is developmentally
normal.
History. The first data on
development of retractile foreskin were provided in 1949 by the famous British
paediatrician, Douglas Gairdner.2 His data have been incorporated into many textbooks and
still is repeated in the medical literature today. 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.2
Unfortunately, Gairdner’s data are inaccurate,3-5 so most healthcare providers have been taught inaccurate
data.4 Retractability usually occurs much later than previously
believed.3-10 This page provides accurate data, derived from newer and
better studies, for healthcare providers.
Current View
Almost all boys are born with the foreskin fused
with the underlying glans penis. Most also have a narrow foreskin that cannot
retract. Non-retractile foreskin is normal at birth and remains common until
after puberty (age 18). 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.
There are three possible conditions that cause
non-retractile foreskin:
·
Fusion of the foreskin
with the glans penis
·
Tightness of the
foreskin orifice
·
Frenulum breve (which is
rare and cannot be diagnosed until the previous two reasons have been
eliminated)
The first two reasons are normal in childhood
and are not pathological in children. The third can be treated
conservatively, retaining the foreskin.
Infants and pre-school. Kayaba et al. (1996) reported that before
six months of age, no boy had a retractable prepuce; 16.5 percent of boys aged
3-4 had a fully retractable prepuce.6 Imamura (1997) examined 4521 infants and young boys. He
reported that the foreskin is retractile in 3 percent of infants aged one to
three months, 19.9 percent of those aged ten to twelve months, and 38.4 percent
of three-year-old boys.7 Ishikawa & Kawakita (2004) reported no retractability at
age one, (but increasing to 77 percent at age 11-15).8 Non-retractile foreskin is the more common condition in this
age group. Compare these data with Gairdner’s data!
Percentage of boys with fused foreskin by age according to Øster
School-age and adolescence. Jakob Øster, a Danish physician who conducted school
examinations, reported his findings on the examination of school-boys in
Denmark, where circumcision is rare.9 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.9 Kayaba et al. (1996) also investigated the
development of foreskin retraction in boys from age 0 to age 15.6 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 11-15.6 Imamura (1997) reported that 77 percent of boys aged 11-15
had retractile foreskin.7 Thorvaldsen & Meyhoff (2005) conducted a survey of 4000
young men in Denmark.10 They report that the mean age of first foreskin retraction
is 10.4 years in Denmark.10 Non-retractile foreskin is the more common condition until
about 10-11 years of age.

Discussion. 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.8,9 There is no “right” age for the foreskin to become
retractable. Non-retractile foreskin does not threaten health in childhood and
no intervention is necessary. Many boys only develop a retractable foreskin
after puberty. Education of concerned parents usually is the only action
required.11
Avoidance of premature retraction. Care-givers and healthcare providers must
be careful to avoid 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 problems,
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.3
Making the foreskin retractable. Occasionally a male reaches adulthood with a non-retractile
foreskin. Some men with a non-retractile foreskin happily go through life and
father children. Other men, however, may want to make their foreskin
retractile.
The foreskin can be made retractable by:
Male circumcision is outmoded as a treatment for
non-retractile foreskin, but it is still recommended by many urologists because
of lack of adequate information, and perhaps because of the fees associated
with circumcision. Nevertheless, circumcision should be avoided because of
pain, trauma, cost,17.18complications,19 difficult recovery, permanent injury to the appearance of
the penis, loss of pleasurable erogenous sensation,20 and impairment of erectile and ejaculatory functions.21-23
A website exists where
knowledgeably individuals give free advice to adults and teens on stretching
one's foreskin to make it retractable.
