Roughly a third of all males worldwide are circumcised, and the practice spans every inhabited continent for reasons that range from ancient religious commandments to modern HIV-prevention campaigns. A 2016 analysis in Population Health Metrics estimated global prevalence at about 37 to 39 percent, with approximately half of those circumcisions performed for religious or cultural reasons and the rest driven by medical, public-health, or secular cultural norms.1PubMed Central. Estimation of country-specific and global prevalence of male circumcision The countries that practice circumcision, and the reasons they do so, vary enormously, and the picture keeps shifting as public-health evidence, insurance policy, and cultural attitudes evolve.
Where Circumcision Is Nearly Universal
In majority-Muslim countries, circumcision rates approach 100 percent. That includes a broad swath of nations across North Africa, the Middle East, Central Asia, and Southeast Asia: Egypt, Saudi Arabia, Iran, Turkey, Indonesia, Malaysia, Bangladesh, Pakistan, and many others. In Islam, circumcision (khitan) is widely regarded as part of the fitrah, a set of practices associated with natural cleanliness and the prophetic tradition. There is theological debate over whether it is strictly obligatory or strongly recommended, but in practice, virtually all Muslim families circumcise their sons, typically in early childhood.2PubMed Central. Bodily integrity and male circumcision: an islamic perspective The global prevalence study assumed 99.9 percent circumcision among Muslim males when country-specific survey data were unavailable, and acknowledged that if the real figure were lower, some national estimates would drop accordingly.1PubMed Central. Estimation of country-specific and global prevalence of male circumcision
Israel is the other country where circumcision is nearly universal. In Judaism, circumcision on the eighth day of life (brit milah) is a covenantal obligation rooted in the Book of Genesis, and it carries enormous religious and communal significance. The procedure is traditionally performed by a mohel, a trained ritual circumciser, though some families now arrange for it to be combined with a hospital surgical setting.2PubMed Central.

Circumcision as a Cultural Rite of Passage
Outside the Abrahamic religious context, circumcision persists as an initiation rite in many communities across sub-Saharan Africa and the Pacific Islands. Among the Xhosa people of South Africa, the ritual known as ulwaluko marks the transition from boyhood to manhood and has been practiced for centuries. The circumcision itself is only one component of a broader initiation process that typically occurs between the ages of 16 and 26, involving seclusion, instruction by elders, and endurance of physical hardship.3PubMed Central. Gay Xhosa men’s experiences of ulwaluko (traditional male initiation) Similar coming-of-age ceremonies, each with their own rituals and timing, exist among Zulu, Sotho, Maasai, Luo, and other ethnic groups across the continent.
In these settings, circumcision carries social weight that has nothing to do with medicine. An uncircumcised adult male may face stigma, exclusion from community leadership, or difficulty finding a marriage partner. These cultural pressures make circumcision rates high in specific ethnic communities even in countries where national rates are otherwise moderate. The practice also developed independently in parts of Aboriginal Australia and pre-Columbian Central and South America, suggesting that the impulse to ritualize the procedure arose in multiple unconnected societies.4Elsevier (Urology).

The English-Speaking Secular Tradition
The United States is the most prominent example of a country where circumcision became widespread for reasons that are neither strictly religious nor tied to a tribal rite of passage. Routine neonatal circumcision took hold in the late 19th and early 20th centuries, initially promoted on Victorian-era hygiene grounds and later reinforced by military medicine and the institutional culture of American hospitals. At its peak in the 1960s and 1970s, the newborn circumcision rate in the U.S. exceeded 80 percent. It has since declined but remains high compared to most of Europe, hovering around 55 to 60 percent nationally in recent years.
Other English-speaking countries followed a similar arc but pulled back earlier. The United Kingdom, Australia, Canada, and New Zealand all saw sharp increases in routine neonatal circumcision through the mid-20th century, followed by steep declines once national medical bodies concluded that the evidence did not support universal recommendation. Today, circumcision rates in England, Australia, and New Zealand sit in the low single digits among non-Muslim, non-Jewish populations, while Canada’s rate is somewhat higher but well below the American figure. The divergence between the U.S. and its cultural peers remains one of the more striking features of the global circumcision map.
Sub-Saharan Africa and the HIV Prevention Campaign
The single biggest shift in the global circumcision landscape over the past two decades has been the massive scale-up of voluntary medical male circumcision (VMMC) in eastern and southern Africa. Three randomized controlled trials conducted in South Africa, Kenya, and Uganda between 2005 and 2007 found that circumcision reduced a man’s risk of acquiring HIV through heterosexual sex by roughly 53 to 60 percent.5PubMed Central. Male circumcision for the prevention of acquisition and transmission of sexually transmitted infections: the case for neonatal circumcision That effect was large enough and consistent enough that the World Health Organization and UNAIDS endorsed VMMC as a key HIV-prevention tool in 2007, specifically for countries with high HIV incidence and low baseline circumcision rates.
Since then, tens of millions of men and adolescents in countries like Kenya, Tanzania, Zambia, Zimbabwe, Malawi, Mozambique, and South Africa have been circumcised through government-sponsored programs, often with substantial international funding. Field effectiveness in real-world rollout has been estimated to exceed 60 percent reduction in HIV acquisition for circumcised men.6PubMed Central. Voluntary Medical Male Circumcision to Reduce HIV Acquisition and Transmission Modeling studies have found that continuing VMMC for even five additional years produces cost savings and health benefits in most sub-Saharan settings, and the intervention is cost-effective in the vast majority of scenarios where HIV incidence is above a moderate threshold.7The Lancet Global Health. Cost-effectiveness of continuation of voluntary medical male circumcision for HIV prevention in sub-Saharan Africa: a modelling study
The protection is not limited to HIV. Evidence from the same landmark trials and subsequent reviews indicates that circumcision also lowers a man’s risk of acquiring herpes simplex virus type 2 by about 28 to 34 percent and reduces the prevalence of human papillomavirus by roughly 32 to 35 percent.5PubMed Central. Male circumcision for the prevention of acquisition and transmission of sexually transmitted infections: the case for neonatal circumcision Broader literature reviews have additionally linked circumcision to a reduced incidence of urinary tract infections.8Journal of Education, Health and Sport. Male Circumcision and Its Long-Term Impact on Infections and Sexual Health: A Literature Review And a meta-analysis of penile cancer risk found a strong protective effect of circumcision performed in childhood or adolescence, with circumcised males roughly a third as likely to develop invasive penile cancer.9PubMed Central. Male circumcision and penile cancer: a systematic review and meta-analysis Penile cancer is rare in any population, but the association is striking because it is almost exclusively a disease of uncircumcised men.10Advances in Urology.

Device Innovation and Task-Shifting
Scaling circumcision to millions of men in resource-limited settings required rethinking how the procedure was delivered. Traditional surgical circumcision demands a trained surgeon, sutures, and a sterile operating environment, all of which are in short supply in rural Africa. Two devices have been central to the scale-up effort: the Shang Ring and the PrePex.
The Shang Ring, a disposable clamp-like device that eliminates the need for suturing, has been on the Chinese market since 2005 and was subsequently tested in multiple African clinical trials. Studies found that it had an excellent safety profile and was relatively easy to teach to non-physician health workers such as nurses and clinical officers, making it well suited for task-shifting in settings with doctor shortages.11PubMed Central. Clinical trials using the Shang Ring device for male circumcision in Africa: a review The PrePex device works differently, using an elastic ring to cut off blood supply to the foreskin without a surgical incision, and was similarly found to be safe and effective for circumcision in adult men across pilot studies in Mozambique, South Africa, Zambia, and Uganda.12PubMed Central. Safety and Efficacy of the PrePex Male Circumcision Device: Results From Pilot Implementation Studies in Mozambique, South Africa, and Zambia13PubMed Central. Adverse events profile of PrePex a non-surgical device for adult male circumcision in a Ugandan urban setting These devices allowed programs to circumcise far more men per day than conventional surgery would have permitted, and they made it feasible to offer the procedure in mobile clinics and community health centers rather than hospitals.
South Korea and Shifting Cultural Tides
South Korea is a fascinating case because it adopted widespread circumcision relatively recently and for reasons that do not fit neatly into any of the usual categories. The practice appears to have been introduced through American military influence during and after the Korean War, and by the early 2000s, South Korea had one of the highest circumcision rates in the world among non-Muslim, non-Jewish countries. A 2002 survey found that about 86 percent of males aged 14 to 29 were circumcised. But the trend has reversed sharply. By 2012, the rate in that same age group had fallen to about 76 percent, and among boys aged 14 to 16, the rate plummeted from 88 percent to 56 percent in a single decade.14PubMed Central. Decline in male circumcision in South Korea
The Korean experience demonstrates how quickly circumcision norms can change when the motivation is cultural rather than religious. Once public discussion about medical necessity increased and younger parents began questioning the assumption that circumcision was a standard part of growing up, rates dropped fast. Religious circumcision traditions tend to be far more resistant to change because they are embedded in theological identity rather than medical fashion.
Complications and Procedural Risks
Circumcision is common enough that its risks sometimes get glossed over, but like any surgery, it carries the potential for complications. A systematic review of complications from male circumcision concluded that complications from neonatal procedures are common enough that healthcare providers need to be better informed about them when counseling families.15PubMed Central. Systematic review of complications arising from male circumcision The most frequent issues are minor: bleeding is the most common early complication, while narrowing of the urethral opening (meatal stenosis) is the most common late one.16PubMed Central. A comprehensive comparison of the early and late complications of surgical circumcision in neonates and children
Severe complications are rare but real. A case analysis of 48 severe complication cases found that the most common was tissue fusion between the foreskin remnant and the glans, followed by meatal stenosis, urethral fistula, and partial amputation of the glans.17Journal of Pediatric Urology. Severe complications of circumcision: An analysis of 48 cases These outcomes are overwhelmingly linked to procedures performed by undertrained practitioners, in non-sterile settings, or without adequate follow-up care. In the context of traditional initiation rites performed in rural areas, complications including infection and even death have been documented, which is one reason public health authorities in countries like South Africa have pushed for greater medical oversight of traditional circumcision practices.
Pain management in neonatal circumcision has also evolved. Decades ago, it was common to perform the procedure with no anesthesia at all, based on the mistaken belief that newborns did not experience pain the way older children and adults do. Current evidence strongly supports combining local anesthesia with non-drug comfort measures like swaddling and sucrose solutions to reduce procedural pain.18PubMed Central. Management of pain in newborn circumcision: a systematic review The extent to which adequate pain control is actually used in practice varies widely by country and provider.
Does Circumcision Affect Sexual Function?
This is one of the most emotionally charged questions in the circumcision debate, and the evidence is clearer than the online arguments suggest. A systematic review that included the highest-quality studies found that circumcision had no overall adverse effect on penile sensitivity, sexual arousal, erectile function, premature ejaculation, orgasm difficulty, sexual satisfaction, or pain during penetration.19PubMed. Does male circumcision affect sexual function, sensitivity, or satisfaction?–a systematic review Some individual studies have reported modest differences in specific outcomes, such as a Danish review that found slightly increased difficulty reaching orgasm in some circumcised men, though it also reported decreased premature ejaculation and some increase in penile sensitivity. Men circumcised at a younger age appear less likely to report any sexual dysfunction than those circumcised later in life.20International Journal of Impotence Research. Circumcision in childhood and male sexual function: a blessing or a curse?
The bottom line from the systematic evidence is that circumcision does not ruin sexual function, but no study can tell any individual man what his subjective experience would have been had the procedure gone differently. That gap between population-level data and individual experience is part of what keeps the debate alive.
The Ethics Debate
In Europe and parts of the Anglosphere, an increasingly vocal debate has emerged over whether parents should be allowed to circumcise infants who cannot consent to an irreversible procedure. The arguments line up on two fairly clear sides. One position holds that every infant has a right to bodily integrity, that removing healthy tissue is only permissible when there is an immediate medical need, and that because circumcision can be deferred until the person is old enough to consent, performing it on a newborn is ethically unjustifiable.21PubMed. Circumcision of male infants as a human rights violation
The counterargument holds that bodily integrity is routinely breached in infancy for the child’s benefit, as in vaccination and other medical interventions, and that the documented health benefits of circumcision are sufficient to place it in that category.22PubMed Central. Non-therapeutic infant male circumcision: Evidence, ethics, and international law perspectives This position is more common among medical bodies in the United States, Israel, and parts of Africa, where the weight of evidence on HIV and STI prevention is factored into the ethical calculus. European medical bodies have generally been more skeptical, with several issuing statements that the benefits are not sufficient to recommend routine circumcision.
Neither side has won the argument, and the debate is unlikely to be resolved by evidence alone because it is fundamentally about values: how much weight to give autonomy versus parental decision-making, how to weigh a small but real surgical risk against a statistical reduction in future disease, and whether religious tradition should factor into medical decisions about a child’s body. These are ethical questions that science can inform but not answer.
How Insurance Policy Shapes Circumcision Rates in the U.S.
In the United States, whether a family’s insurance covers the procedure turns out to be a powerful predictor of whether their son gets circumcised. Neonates with private insurance have roughly double the odds of being circumcised compared to those on public insurance.23PubMed. State-Level Public Insurance Coverage and Neonatal Circumcision Rates Over the past several decades, 18 states have dropped Medicaid coverage for newborn circumcision, and the effects have been immediate and measurable. When Florida and North Carolina stopped covering the procedure through Medicaid, circumcision rates among publicly insured newborns dropped by 30 to 40 percent.24PubMed Central. Impact of Health Insurance Type on Trends in Newborn Circumcision, United States, 2000 to 2010 California’s 1982 decision to defund Medicaid circumcision was associated with a 25 to 31 percentage point decrease in circumcision rates among Medicaid-covered births, the earliest documented evidence that funding coverage directly affects rates and magnifies healthcare disparities.25PubMed. The 1982 Medicaid Funding Cessation for Circumcision in California and Circumcision Rates
This creates an unusual dynamic. Much of the decline in U.S. circumcision rates over the past two decades turns out to be less about changing attitudes and more about changing insurance. As the share of births covered by Medicaid has risen, and as more states have stopped covering the procedure, the national rate has drifted down even though circumcision rates among privately insured families have remained relatively stable. The implication is that for many American families, circumcision is less a firmly held belief and more a default choice that is easily disrupted when the out-of-pocket cost becomes visible.
Countries Where Circumcision Is Rare
Most of Europe, East Asia (excluding South Korea and the Philippines), and Latin America have circumcision rates in the low single digits among the general non-Muslim population. In countries like Japan, China, most of South America, and Scandinavia, circumcision is essentially unheard of outside of small religious minorities or specific medical indications like phimosis. These regions never adopted the 19th-century Anglo-American medicalization of the procedure, and there has been no public-health rationale to introduce it because HIV transmission patterns differ from those in sub-Saharan Africa.
The Philippines is a notable exception in East Asia. Near-universal circumcision (locally called tuli) persists as a cultural norm unrelated to Islam in most of the population, driven by peer pressure, perceived hygiene benefits, and a coming-of-age tradition. Boys who have not been circumcised by their early teens often face social ridicule, making the practice self-reinforcing even without a formal religious mandate.
Understanding the global map of circumcision requires holding multiple explanations in mind simultaneously. No single reason accounts for the practice in all the places it exists. Religious law drives it across the Muslim world and in Jewish communities. Ancient initiation traditions sustain it in parts of Africa and the Pacific. A century of medical culture embedded it in the English-speaking world. And a 21st-century public health emergency catalyzed its expansion across a dozen African nations where it had not been widespread before. Each of these motivations produces a different relationship to the procedure: unquestioned sacred obligation in one context, a contested parental choice in another, a life-saving intervention in a third.
