Medical Benefits from Circumcision
by Dr. Brian J. Morris
from Circ-Online
Circumcision has historically been a topic of emotive and
often irrational debate. At least part of the reason is that
a sex organ is involved. (Compare, for example, ear piercing.)
During the past two decades the medical profession have tended
to advise parents not to circumcise their baby boys. In fact
there have even been reports of harrassment by medical professionals
of new mothers, especially those belonging to religious groups
that practice circumcision, in an attempt to stop them having
this procedure carried out. Such attitudes are a far cry from
the situation years ago when baby boys were circumcised routinely
in Australia. But over the past 20 years the rate has declined
to as low as 10%.
However, a reversal of this trend is starting to occur. In the
light of an increasing volume of medical scientific
evidence (many publications cited below) pointing to the
benefits of neonatal circumcision a new policy statement was
formulated by a working party of the Australian College of Paediatrics
in August 1995 and adopted by the College in May 1996 [2] . In this document
medical practitioners are now urged to fully inform parents of
the benefits of having their male children circumcised. Similar
recommendations were made recently by the Canadian Paediatric
Society who also conducted an evaluation of the literature, although
concluded that the benefits and harms were very evenly balanced.
As discussed below the American College of Pediatrics has moved
far closer to an advocacy position.
In the present article I would like to focus principally on the
protection afforded by circumcision against infections, including
sexually transmitted diseases (STDs). I might add that I am a
university academic who teaches medical and science students
and who does medical research, including that involving genital
cancer virology. I am not Jewish, nor a medical practitioner
or lawyer, so have no religious bias or medico-legal concerns
that might get in the way of a rational discussion of this issue.
The increased risk of infection may be a consequence of the fact
that the foreskin presents the penis with a larger surface area,
the moist skin under it represents a thinner epidermal barrier
than the drier, more cornified skin of the circumcised penis,
the presence of a prepuce is likely to result in greater microtrauma
during sexual intercourse and, as one might expect, the warm,
moist mucosal environment under the foreskin favours growth of
micro-organisms.
In the 1950s and 60s 90% of boys in the USA and Australia were
circumcised soon after birth. The major benefits at that time
were seen as improved lifetime genital hygiene, elimination of
phimosis (inability to retract the foreskin) and prevention of
penile cancer. The trend not to circumcise started about 20 years
ago, after the American Academy of Paediatrics Committee for
the Newborn stated, in 1971, that there are ?no valid medical
indications for circumcision?. In 1975 this was modified to ?no
absolute valid ... ?, which remained in the 1983 statement, but
in 1989 it changed significantly to ?New evidence has suggested
possible medical benefits ...? [49]
.
Dr Edgar Schoen, Chairman of the Task Force on Circumcision of
the American Academy of Pediatrics, has stated that the benefits
of routine circumcision of newborns as a preventative health
measure far exceed the risks of the procedure [48] . During the period 1985-92
there was an increase in the frequency of postnewborn circumcision
and during that time Schoen points out that the association of
lack of circumcision and urinary tract infection has moved from
?suggestive? to ?conclusive? [48]
. At the same time associations with other infectious agents,
including HIV, have been demonstrated. In fact he goes on to
say that ?Current newborn circumcision may be considered a preventative
health measure analogous to immunization in that side
effects and complications are immediate and usually minor, but
benefits accrue for a lifetime? [48]
.
Benefits included: a decrease in physical problems such as phimosis
[36] , reduction
in balanitis (inflammation of the glans, the head of the penis)
[17] , reduced
urinary tract infections, fewer problems with erections at puberty,
decreased sexually transmitted diseases (STDs), elimination of
penile cancer in middle-aged men and, in addition, in older men,
a decrease in urological problems and infections [reviewed in:
2, 18, 30,
44, 47, 49].
Therefore the benefits are different at different ages.
Neonatologists only see the problems of the operation itself.
However, urologists who deal with the problems of uncircumcised
men cannot understand why all newborns are not circumcised [47, 48] . The demand for circumcision
later in childhood has increased, but, with age, problems, such
as anaesthetic risk, are higher. Thus Schoen states ?Current
evidence concerning the life-time medical benefit of newborn
circumcision favours an affirmative choice? [48] .
In a letter written by Dr Schoen to Dr Terry Russell in Brisbane
in 1994 Schoen derides an organization known as ?NOCIRC? for
their use of ?distortions, anecdotes and testimonials to try
to influence professional and legislative bodies and the public,
stating that in the past few years they have become increasingly
desperate and outrageous as the medical literature has documented
the benefits. For example they have compared circumcision with
female genital mutilation, which is equivalent to cutting off
the penis. In 1993 the rate of circumcision had risen to 80%
in the USA and Schoen suggests that ?Perhaps NOCIRC has decided
to export their ?message? to Australia since their efforts are
proving increasingly futile in the US?. He also noted that when
Chairman of the Task Force his committee was bombarded with inaccurate
and misleading communications from this group. Another of these
groups is ?UNCIRC?, which promotes procedures to reverse circumcision,
by, for example, stretching the loose skin on the shaft of the
retracted penis. Claimed benefits of ?increased sensitivity?
in reality appear to be a result of the friction of the foreskin,
whether intact or newly created, on the moist or sweaty glans
and undersurface of the prepuce in the unaroused state and would
obviously in the ?re-uncircumcised? penis have nothing to do
with an increase in touch receptors. The sensitivity during sexual
intercourse is in fact identical, according to men circumcised
as adults.
Another respected authority is Dr Tom Wiswell, who states ?As
a pediatrician and neonatologist, I am a child advocate and try
to do what is best for children. For many years I was an outspoken
opponent of circumcision ... I have gradually changed my opinion?
[56, 57] . This ability
to keep an open mind on the issue and to make a sound judgement
on the balance of all available information is to his credit
? he did change his mind!
The complication rates of having or not having the procedure
have been examined. Amongst 136,000 boys born in US army hospitals
between 1980 and 1985, 100,000 were circumcised and 193 (0.19%)
had complications, with no deaths [58]
. Of the 36,000 who were not circumcised the complication rate
was 0.24% and there were 2 deaths [58]
. In 1989 of the 11,000 circumcisions performed at New York?s
Sloane Hospital, only 6 led to complications, none of which were
fatal [44]
. Also no adverse psychological aftermath has been demonstrated
[46] . Cortisol
levels have registered an increase during and shortly after the
procedure, indicating that the baby is not unaware of the procedure
in its unanaesthetized state and one has to weigh up the need
to inflict this short term pain in the context of a lifetime
of gain from prevention or reduction of subsequent problems.
Anaesthetic creams and other means appear to be at least partially
effective in reducing trauma and some babies show no signs of
distress at all when the procedure is performed without anaesthetic.
The proponents of not circumcising nevertheless stress that lifelong
penile hygiene is required. This acknowledges that something
harmful or unpleasant is happening under the prepuce. Moreover,
a study of British schoolboys found that penile hygiene does
not exist [44]
. Furthermore, Dr Terry Russell, writing in the Medical Observer
states ?What man after a night of passion is going to perform
penile hygiene before rolling over and snoring the night away
(with pathogenic organisms multiplying in the warm moist environment
under the prepuce)? [44]
.
The reasons for circumcision, at least in a survey carried out
as part of a study at Sydney Hospital, were: 3% for religious
reasons, 1-2% for medical, with the remainder presumably being
?to be like dad? or a preference of one or both parents for whatever
reason [16]
. The actual proportion of men who were circumcised when examined
at this clinic was 62%. Of those studied, 95% were Caucasian,
with younger men just as likely to be circumcised as older men.
In Adelaide a similar proportion has been noted, with 55% of
younger men being circumcised. In Britain, however, the rate
is only 7-10%, much like Europe, and in the USA, as indicated
above, the rate of circumcision has always been high [16] .
Neonatal urinary tract infections
A study by Wiswell of 400,000 newborns over the period 1975-84
found that the uncircumcised had an 11-fold higher incidence
of urinary tract infections (UTIs) [58]
. During this decade the frequency of circumcision in the USA
decreased from 84% to 74% and this decrease was associated with
an increase in rate of UTI [61]
. UTI was lower in circumcised, but higher in uncircumcised.
In a 1982 series 95% of UTI cases were in uncircumcised [60] . A study by Roberts
in 1986 found that 4% of uncircumcised boys got UTI, compared
with 0.4% of girls and 0.2% of circumcised boys [42] . This indicated a 20-fold higher
risk for uncircumcised boys. In a 1993 study by Wiswell of 200,000
infants born between 1985 and 1990, 1000 got UTI in their first
year of life [59]
. The number was equal for boys and girls, but was 10-times higher
for uncircumcised boys. Of these 23% had bacteraemia. The infection
can travel up the urinary tract to affect the kidney and higher
rate of problems such as pyelonephritis is seen in uncircumcised
children [43,
52] . These
and other reports [e.g., 21, 43,
52] all point to the benefits of circumcision
in reducing UTI.
Indeed, Wiswell performed a meta-analysis of all 9 previous studies
and found that every one indicated an increase in UTI in the
uncircumcised [59]
. The average was 12-fold higher and the range was 5 to 89-fold,
with 95% confidence intervals of 11-14 [59] . Meta-analyses by others have
reached similar conclusions. Other studies, including one of
men with an average age of 30 years, have indicated that circumcision
also reduces UTI in adulthood [51]
. The fact that the bacterium E. coli , which is pathogenic
to the urinary tract, has been shown to be capable of adhering
to the foreskin, satisfies one of the criteria for causality
[52, 62, and refs in 18]. Since the absolute risk of UTI in uncircumcised
boys is approx. 1 in 25 (0.05) and in circumcised boys is 1 in
500 (0.002), the absolute risk reduction is 0.048. Thus 20 baby
boys need to be circumcised to prevent one UTI. However, the
potential seriousness and pain of UTI, which can in rare cases
even lead to death, should weigh heavily on the minds of parents.
The complications of UTI that can lead to death are: kidney failure,
meningitis and infection of bone marrow. The data thus show that
much suffering has resulted from leaving the foreskin intact.
Lifelong genital hygiene in an attempt to reduce such infections
is also part of the price that would have to be paid if the foreskin
were to be retained. However, given the difficulty in keeping
bacteria at bay in this part of the body [38, 48]
, not performing circumcision would appear to be far less effective
than having it done in the first instance [48] .
Sexually-transmitted diseases
Early studies showed higher rates of gonococcal and nonspecific
urethritis in uncircumcised men [39,
48] . Recent
studies have yielded similar findings. In addition, the earlier
work showed higher chancroid, syphilis, papillomavirus and herpes
[53] . However,
there were methodological problems with the design of these studies,
leading to criticisms. As a result there is still no overwhelming
agreement. In 1947 a study of 1300 consecutive patients in a
Canadian Army unit showed that being uncircumcised was associated
with a 9-fold higher risk of syphilis and 3-times more gonorrhea
[55] . At
the University of Western Australia a 1983 study showed twice
as much herpes and gonorrhea, 5-times more candidiasis and 5-fold
greater incidence of syphilis [39]
. In South Australia a study in 1992 showed that uncircumcised
men had more chlamidia (odds ratio 1.3) and gonoccocal infections
(odds ratio 2.1). Similarly in 1988 a study in Seattle of 2,800
heterosexual men reported higher syphilis and gonnorrhea in uncircumcised
men, but no difference in herpes, chlamidia and non-specific
urethritis (NSU). Like this report, a study in 1994 in the USA,
found higher gonnorhea and syphilis, but no difference in other
common STDs [12]
. In the same year Dr Basil Donovan and associates reported the
results of a study of 300 consecutive heterosexual male patients
attending Sydney STD Centre at Sydney Hospital [16] . They found no difference in
genital herpes, seropositivity for HSV-2, genital warts and NSU.
As mentioned above, 62% were circumcised and the two groups had
a similar age, number of partners and education. Gonorrhea, syphilis
and hepatitis B were too uncommon in this Sydney study for them
to conclude anything about these. Thus on the bulk of evidence
it would seem that at least some STDs may be more common in the
uncircumcised, but this conclusion is by no means absolute and
the incidence may be influenced by factors such as the degree
of genital hygiene, availability of running water and socioeconomic
group being studied.
Cancer of the penis
The incidence of penile cancer in the USA is 1 per 100,000 men
per year (i.e., 750-1000 cases annually) and mortality rate is
25-33% [27,
31] . It
represents approximately 1% of all malignancies in men in the
USA. This data has to be viewed, moreover, in the context of
the high proportion of circumcised men in the USA, especially
in older age groups, and the age group affected, where older
men represent only a portion of the total male population. In
a study in Melbourne published in Australasian Radiology
in 1990, although 60% of affected men were over 60 years of age,
40% were under 60 [45]
. In 5 major series in the USA since 1932, not one man with penile
cancer had been circumcised neonatally [31] , i.e., this disease only occurs
in uncircumcised men and, less commonly, in those circumcised
after the newborn period. The proportion of penile malignancies
as a fraction of total cancers in uncircumcised men would thus
be considerable. The predicted life-time risk has been estimated
as 1 in 600 in the USA and 1 in 900 in Denmark [27] . In under-developed countries
the incidence is higher: approx. 3-6 cases per 100,000 per year
[27] .
The so-called ?high-risk? papillomavirus types 16 and 18 (HPV
16/18) are found in a large proportion of cases and there is
good reason to suspect that they are involved in the causation
of this cancer, as is true for most cases of cervical cancer
(see below). HPV 16 and 18 are, moreover, more common in uncircumcised
males [35]
. These types of HPV produce flat warts that are normally only
visible by application of dilute acetic acid (vinegar) to the
penis and the data on high-risk HPVs should not be confused with
the incidence figures for genital warts, which although large
and readily visible, are caused by the relatively benign HPV
types 6 and 11. Other factors, such as poor hygiene and other
STDs have been suspected as contributing to penile cancer as
well [8, 31] .
In Australia between 1960 and 1966 there were 78 deaths from
cancer of the penis and 2 from circumcision. (Circumcision fatalities
these days are virtually unknown.) At the Peter McCallum Cancer
Institute 102 cases of penile cancer were seen between 1954 and
1984, with twice as many in the latter decade compared with the
first. Moreover, several authors have linked the rising incidence
of penile cancer to a decrease in the number of neonatal circumcisions
[13, 45] . It would thus
seem that ?prevention by circumcision in infancy is the best
policy?.
Cervical cancer in female partners of uncircumcised men
A number of studies have documented higher rates of cervical
cancer in women who have had one or more male sexual partners
who were uncircumcised. These studies have to be looked at critically,
however, to see to what extent cultural and other influences
might be contributing in groups with different circumcision practices.
In a study of 5000 cervical and 300 penile cancer cases in Madras
between 1982 and 1990 the incidence was low amongst Muslim women,
when compared with Hindu and Christian, and was not seen at all
in Muslim men [22]
. In a case-control study of 1107 Indian women with cervical
cancer, sex with uncircumcised men or those circumcised after
the age of 1 year was reported in 1993 to be associated with
a 4-fold higher risk of cervical cancer, after controlling for
factors such as age, age of first intercourse and education [1] . Another study
published in 1993 concerning various types of cancer in the Valley
of Kashmir concluded that universal male circumcision in the
majority community was responsible for the low rate of cervical
cancer compared with the rest of India [14] . In Israel, a 1994 report of
4 groups of women aged 17-60 found that gynaecologically healthy
Moshav residents had no HPV 16/18, whereas healthy Kibbutz residents
had a 1.8% incidence [24]
. Amongst those with gynaecological complaints HPV 16/18 was
found in 9% of Jewish and 12% of non-Jewish women. HPV types
16 and 18 cause penile intraepithelial neoplasia (PIN) and a
study published in the New England Journal of Medicine
in 1987 found that women with cervical cancer were more likely
to have partners with PIN, the male equivalent of cervical intraepithelial
neoplasia (CIN) [6]
. Thus the epidemic of cervical cancer in Australia, and indeed
most countries in the world, would appear to be due at least
in part to the uncircumcised male and would therefore be expected
to get even worse as the large proportion that were born in the
past 10-20 years and not circumcised reach sexual maturity.
AIDS virus
In the USA the estimated risk of HIV per heterosexual exposure
is 1 in 10,000 to 1 in 100,000. If one partner is HIV positive
and otherwise healthy then a single act of unprotected vaginal
sex carries a 1 in 300 risk for a woman and as low as a 1 in
1000 risk for a man [9]
. (The rates are very much higher for unprotected anal sex and
intravenous injection). In Africa, however, the rate of HIV infection
is up to 10% in some cities. (A possible reason for this big
difference will be discussed later.) In Nairobi it was first
noticed that among 340 men being treated for STDs they were 3-times
as likely to be HIV positive if they had genital ulcers or were
uncircumcised (11% of these men had HIV) [50] . Subsequently another report
showed that amongst 409 African ethnic groups spread over 37
countries the geographical distribution of circumcision practices
indicated a correlation of lack of circumcision and high incidence
of AIDS [7]
. In 1990 Moses in International Journal of Epidemiology
reported that amongst 700 African societies involving 140 locations
and 41 countries there was a considerably lower incidence of
HIV in those localities where circumcision was practiced [33, 34] . Truck drivers, who generally
exhibit more frequent prostitute contact, have shown a higher
rate of HIV if uncircumcised. Interestingly, in a West African
setting, men who were circumcised but had residual foreskin were
more likely to be HIV-2 positive than those in whom circumcision
was complete [40]
.
Of 26 cross-sectional studies, 18 have reported statistically
significant association [e.g., 15, 23,
25, 54], by univariate and
multivariate analysis, between the presence of the foreskin and
HIV infection, and 4 reported a trend. The findings have, moreover,
led various workers such as Moses and Caldwell to propose that
circumcision be used as an important intervention strategy in
order to reduce AIDS [9, 19,
23, 26, 32-34].
Perhaps the most interesting study of the risk of HIV infection
imposed by having a foreskin is that by Cameron, Plummer and
associates published as a large article in Lancet in 1989
[10] . This
had the advantage of being prospective. It was conducted in Nairobi.
These workers followed HIV negative men until they became infected.
The men were visiting prostitutes, numbering approx. 1000, amongst
whom there had been an explosive increase in the incidence of
HIV from 4% in 1981 to 85% in 1986. These men were thus at high
risk of exposure to HIV, as well as other STDs. From March to
December 1987, 422 men were enrolled into the study. Of these,
51% had presented with genital ulcer disease (89% chancroid,
4% syphilis, 5% herpes) and the other 49% with urethritis (68%
being gonorrhea). 12% were initially positive for HIV-1. Amongst
the whole group, 27% were not circumcised. They were followed
up each 2 weeks for 3 months and then monthly until March 1988.
During this time 8% of 293 men seroconverted (i.e., 24 men),
the mean time being 8 weeks. These displayed greater prostitute
contact per month (risk ratio = 3), more presented with genital
ulcers (risk ratio = 8; P <0.001) and more were uncircumcised
(risk ratio = 10; P <0.001). Logistic regression analysis
indicated that the risk of seroconversion was independently associated
with being uncircumcised (risk ratio = 8.2; P <0.0001),
genital ulcers (risk ratio = 4.7; P = 0.02) and regular
prostitute contact (risk ratio = 3.2; P = 0.02). The cumulative
frequency of seroconversion was 18% and was only 2% for men with
no risk factors, compared to 53% for men with both risk factors.
Only one circumcised man with no ulcer seroconverted. Thus 98%
of seroconversion was associated with either or both cofactors.
In 65% there appeared to be additive synergy, the reason being
that ulcers increase infectivity for HIV. This involves increased
viral shedding in the female genital tract of women with ulcers,
where HIV-1 has been isolated from surface ulcers in the genital
tract of HIV-1 infected women.
It has been suggested that the foreskin could physically trap
HIV-infected vaginal secretions and provide a more hospitable
environment for the infectious innoculum. Also, the increased
surface area, traumatic physical disruption during intercourse
and inflammation of the glans penis (balanitis) could aid in
recruitment of target cells for HIV-1. The port of entry could
potentially be the glans, subprepuce and/or urethra. In a circumcised
penis the dry, cornified skin may prevent entry and account for
the findings.
In this African study the rate of transmission of HIV following
a single exposure was 13% (i.e., very much higher than in the
USA). It was suggested that concomitant STDs, particularly chancroid
[9] , may
be a big risk factor, but there could be other explanations as
well. Studies in the USA have not been as conclusive. Some studies
have shown a higher incidence in uncircumcised men. Others do
not. In New York City, for example, no correlation was found,
but the patients were mainly intravenous drug users and homosexuals,
so that any existing effect may have been obscured. A study in
Miami, however, of heterosexual couples did find a higher incidence
in men who were uncircumcised, and, in Seattle homosexual men
were twice as likely to be HIV positive if they were uncircumcised
[28] .
The reason for the big difference in apparent rate of transmission
of HIV in Africa and Asia, where heterosexual exposure has led
to a rapid spread through these populations and is the main method
of transmission, compared with the very slow rate of penetration
into the heterosexual community in the USA and Australia, now
appears to be related at least in part to a difference in the
type of HIV-1 itself [29]
. In 1995 an article in Nature Medicine discussed findings
concerning marked differences in the properties of different
HIV-1 subtypes in different geographical locations [37] . A class of HIV-1
termed ?clade E? is prevalent in Asia and differs from the ?clade
B? found in developed countries in being highly capable of infecting
Langerhans cells found in the foreskin, so accounting for its
ready transmission across mucosal membranes. The Langerhans cells
are part of the immune system and in turn carry the HIV to the
T-cells, whose numbers are severely depleted as a key feature
of AIDS. The arrival of the Asian strain in Australia was reported
in Nov 1995 and has the potential to utilise the uncircumcised
male as a vehicle for rapid spread through the heterosexual community
of this country in a similar manner as it has done in Asia. It
could thus be a time-bomb about to go off and should be a major
concern for health officials.
To summarize:
Lack of circumcision:
- Is the biggest risk factor for heterosexually-acquired AIDS
virus infection in men (8-times higher risk by itself, and even
higher when lesions from STDs are added in).
- Is responsible for a 12-fold higher risk of urinary tract
infections.
- Carries a higher risk of death in the first year of life
(from complications of urinary tract infections: kidney failure,
meningitis and infection of bone marrow).
- One in ~600-900 uncircumcised men will die from cancer of
the penis or require at least partial penile amputation as a
result. (In contrast, penile cancer never occurs in men
circumcised at birth). (Data from studies in the USA, Denmark
and Australia, which are not to be confused with the often quoted,
but misleading, annual incidence figures of 1 in 100,000).
- Often leads to balanitis (inflammation of the glans), phimosis
(inability to retract the foreskin) and paraphimosis (constriction
of the penis by a tight foreskin). Up to 18% of uncircumcised
boys will develop one of these by 8 years of age, whereas all
are unknown in the circumcised.
- Means problems that may result in a need for circumcision
late in life: complication risk = 1 in 100 (compared with
1 in 1000 in the newborn).
- Is associated with higher incidence of cervical cancer in
the female partners of uncircumcised men.
There is no evidence of any long-term psychological harm arising
from circumcision. The risk of damage to the penis is extremely
rare and avoidable by using a competent, experienced doctor.
Surgical methods use a procedure that protects the penis during
excision of the foreskin. As an alternative, for those who might
prefer it, a device (PlastiBell) is in use that clamps the foreskin,
which then falls off after a few days, and so eliminates the
need to actually cut the foreskin off [20] . For some, cultural or religious
beliefs dictate the method.
Sociological aspects
Finally, a brief mention of other findings relating to circumcision
in the setting of Australia.
In a survey of circumcised vs uncircumcised men and their partners
that was conducted by Sydney scientist James Badger [4, 5] (who regards himself as neutral
on the issue of circumcision) it was found that:
- 18% of uncircumcised males underwent circumcision later in
life anyway.
- 21% of uncircumcised men who didn't, nevertheless wished
they were circumcised. (There were also almost as many men who
wished they hadn?t been circumcised and it could be that at least
some men of either category may have been seeking a scapegoat
for their sexual or other problems. In addition, this would no
doubt be yet another thing parents could be blamed for by their
children, whatever their decision was when the child was born.)
- No difference in sexual performance (consistent with Masters
& Johnson).
- Slightly higher sexual activity in circumcised men.
- No difference in frequency of sexual intercourse for older
uncircumcised vs. circumcised men.
- Men circumcised as adults were very pleased with the result.
The local pain when they awoke from the anaesthetic was quickly
relieved by pain killers (needed only for one day), and all had
returned to normal sexual relations within 2 weeks, with no
decrease in sensitivity of the penis and claims of 'better
sex'. (Badger?s findings are, moreover, consistent with every
discussion I have ever had with men circumcised as adults. The
only case to the contrary was a testimonial in a letter I received
in the mail from a member of UNCIRC.)
- Women with circumcised lovers were more likely to reach a
simultaneous climax.
- Women with uncircumcised lovers were 3 times as likely to
fail to reach orgasm. (These data could, however, possibly reflect
behaviours of uncircumcised males that might belong to lower
socio-economic classes and/or ethnic groups whose attitudes may
differ from groups in which circumcision is more common.)
- Circumcision was favoured by women for appearance and hygiene.
(Furthermore, some women were nauseated by the smell of the uncircumcised
penis, where, as mentioned above bacteria and other micro-organisms
proliferate under the foreskin.)
- The uncircumcised penis was found by women to be easier to
elicit orgasm by hand.
- The circumcised penis was favoured by women for oral sex.
Why are human males born with a foreskin?
The foreskin probably protected the head of the penis from long
grass, shrubbery, etc when humans wore no clothes, where evolutionarily
our basic physiology and psychology are little different than
our cave-dwelling ancestors. However, Dr Guy Cox from The University
of Sydney has recently supplemented this suggestion with a novel
idea, namely that the foreskin could be the male equivalent of
the hymen, and served as an impediment to sexual intercourse
during adolescence [11]
. The ritual removal of the foreskin in diverse human traditional
cultures, ranging from Muslims to Aboriginal Australians, is
a sign of civilization in that human society acquired the ability
to control through education and religion the age at which sexual
intercourse could begin. Food for thought and discussion!
Conclusion
The information available today will assist medical practitioners,
health workers and parents by making advice and choices concerning
circumcision much more informed. Although there are benefits
to be had at any age, they are greater the younger the child.
Issues of ?informed consent? may be analogous to those parents
have to consider for other medical procedures, such as whether
or not to immunize their child. The question to be answered is
?do the benefits outweigh the risks?. When considering each factor
in isolation there could be some difficulty in choosing. However,
when viewed as a whole, in my opinion the answer to whether to
circumcise a male baby is ?yes?. Nevertheless, everybody needs
to weigh up all of the pros and cons for themselves and make
their own best decision. I trust that the information I have
provided in this article will help in the decision-making process.
