History

A history of confidently wrong advice

It's tempting to treat "the current medical advice" as timeless truth, medical knowledgde is ever evolving. Medical advice about the foreskin has a documented track record of reversals, quiet deletions, and instructions that later had to be explicitly retracted. Knowing that history is not anti-medicine — it's the opposite. It's how you hold current claims to the standard the old ones failed.

Every item below is sourced. This is a page about misinformation; it would be self-defeating to add any.

Before the 1870s

The baseline: circumcision was rare

Before American physicians took an interest in it, routine circumcision barely existed in the United States — much as it still doesn't across most of the world today. Outside specific religious communities, the general population was, by default, left intact.[11]

1870

The theory that got American medicine interested in the first place

Orthopedic surgeon Lewis Sayre presented a theory to the American Medical Association that genital irritation, including from an unretractable foreskin (normal in children — see Care), could act on the nervous system and cause unrelated problems elsewhere in the body, with circumcision offered as the fix.[30] Sayre later served as AMA president, and the idea, however dated it looks now, is a significant part of why American medicine started recommending circumcision at all. It was a theory of disease, not a hygiene or infection argument, that got this started.

1888

The anti-masturbation rationale, in print

In Plain Facts for Old and Young, John Harvey Kellogg recommended circumcision of boys as a remedy for masturbation — and specified it be done without anesthetic, because the pain was, in his framing, part of the point.[1]

Sayre's theory (above) got doctors' attention; this is what took the practice to a mass audience — not as infection control, but as behavioral control, resting on a theory of disease that was entirely false. The practice survived both rationales; each one was quietly swapped out for the next.

1914–1940s

The government told parents to retract infants US Government

The U.S. Children's Bureau published Infant Care (Bureau Publication No. 8) from 1914 onward — a federal parenting manual distributed to millions of American families and revised for decades.

On the care of an intact infant it instructed parents directly. Under "Genital Organs," it advised that a physician should check for adhesions "between the foreskin and the glans which should be separated," and then told parents to retract:

Infant Care, 1940 — what it told parents

Two or three times a week the foreskin should be drawn back until the raised edge of the glans is visible, and the organ then cleansed. A physician should decide whether adhesions "should be separated" and "whether circumcision is needed."[2]

What every pediatric body now says

Never retract an infant's foreskin. It is fused to the glans by design and separates on its own over years. Forcing it causes pain, bleeding, scarring, and infection.[3]

The significance is not just that the advice was wrong. It's that the advice was harm-causing. Forcing separation of a naturally-fused foreskin tears the tissue, and the resulting scarring can produce pathological phimosis — the exact condition then used to justify circumcision giving the foreskin the appearance of being problematic. Generations of parents were instructed to create the problem the surgery was sold to fix. See how natural separation actually works and why forced retraction is harmful.

1941

The anti-masturbation case goes mass-market

Johns Hopkins obstetrician Allan Guttmacher took the 1888 rationale (above) straight to parents, in Parents Magazine — a mass-circulation title with a readership in the hundreds of thousands, approaching a million by 1946. His argument: circumcision "causes some blunting of male sexual sensitivity," and that blunting was the point, since a less sensitive penis meant a boy was less likely to handle himself and "masturbation is considered less likely."[17]

1949

The paper that changed British practice UK / medicine

Douglas Gairdner's 1949 British Medical Journal paper "The Fate of the Foreskin" documented that the infant foreskin is normally non-retractable, separates over years, and that routine circumcision carried real risks including death. It is widely credited with helping end routine infant circumcision in Britain.[5]

The UK and the US had access to the same evidence at the same time. One country changed course; the other did not. That divergence is hard to explain on purely medical grounds.

1971

"No valid medical indication" — then decades of drift AAP / medicine

The American Academy of Pediatrics stated in 1971[15], and reaffirmed in 1975[16], that there was no valid medical indication for routine neonatal circumcision. Yet US rates remained high for decades, and hospital practice lagged far behind the stated position — an early, clear example of the gap between what the guidance said and what was actually done to newborns.

The lesson worth carrying forward: "the official position" and "what hospitals routinely do" are two different things, and they can diverge for a very long time.

Until 1977

Insurance was still paying for the female version of this Insurance / medicine

Female circumcisions were performed by American physicians well into the twentieth century, medically justified on much the same anti-masturbation grounds used for the male procedure (see 1888, above), alongside diagnoses like "hysteria". The practice was mainstream enough that Blue Cross Blue Shield covered it as a routine medical procedure until 1977 — nearly two decades before any form of female genital cutting was federally banned in the United States.[10]

The point isn't to equate the two procedures or their severity. It's narrower: the same country's medical establishment gave institutional, insured legitimacy to a genital-cutting practice that today we view as cruel, and eventually stopped.

1888–1979

The masturbation rationale still needed debunking, in print, nine decades later

Kellogg's 1888 rationale (see above) never had a medical basis, and it didn't quietly disappear once doctors knew better. A 1970 urology textbook was still advising it on those grounds, and even Dr. Spock's Baby and Child Care — the best-selling parenting manual in America — was still arguing parents out of it directly as late as a 1979 printing.[8][9]

1979–1981

The peak: roughly 65% of newborn boys

The most reliable year-by-year figures available (CDC hospital-discharge records) peak right around here, at roughly 65%.[14]

1982

California becomes the first state to stop paying for it California / Medicaid

In 1982, California became the first state to end Medicaid coverage for routine infant circumcision — treating it as the elective procedure it is, rather than medically necessary care the public should subsidize.[12]

The effect was immediate and measurable: among Medicaid-covered births in the western United States, circumcision rates fell from roughly 56% in 1979–81 to about 27% in 1983–85, a drop tied directly to the funding change, not a broader regional trend.[12] But the natural experiment is about as clean as this debate ever gets: remove the subsidy, and a large share of parents who would otherwise have had it done didn't.

1984 → later editions

The AAP pamphlet that lost its paragraph AAP

The 1984 AAP parent pamphlet Care of the Uncircumcised Penis contained a passage describing what the foreskin actually does — that it protects the glans throughout life, and that removing that protection can expose the glans and urinary opening to irritation, meatitis, and meatal stenosis, problems it noted "virtually never occur in uncircumcised" boys.

1984 pamphlet — included

Described the foreskin's protective function explicitly, and noted that certain problems of the exposed glans "virtually never occur" in intact males.[4]

Later editions — removed

The paragraph describing the foreskin's benefits was deleted. When asked why, AAP staff stated they were unable to determine the reason it had been taken out.[4]

When a researcher pressed the AAP on the deletion, the documented correspondence shows the organization could not or would not explain who removed it or why; one reviewer response attributed it to a "reorganization" that a comparison of editions did not bear out.[4] Draw your own conclusion — but a professional body removing an accurate description of a body part's function, and then being unable to say why, is at minimum a strange thing to have on the record.

1997–1999

The survey that found infants were still cut without pain relief AAP / medicine

A national survey of US physicians performing newborn circumcision found that a majority — 55% — used no pain relief of any kind. Not "no general anesthesia": nobody puts a newborn to sleep for this. No pain relief at all — no numbing shot, no numbing cream, nothing. The procedure was still routinely carried out on the old assumption that a newborn doesn't feel or remember pain.[6]

The AAP's 1999 circumcision policy statement was the first to explicitly recommend that adequate analgesia be provided whenever the procedure is performed. Read the other way, that recommendation is an admission: for essentially the entire history of routine neonatal circumcision in the US up to that point, it had been standard practice to perform it on an unanesthetized infant.[7]

Sit with the timeline for a second. The debate over whether to circumcise had run for over a century before the profession's own guidance caught up to the plain fact that the newborn having it done to him could feel it happening.

2012 → 2017

The position statement quietly expires AAP / medicine

The AAP's 2012 policy — the same one that first claimed circumcision's "health benefits… outweigh the risks" — carried its own five-year expiration clause: AAP policy statements automatically lapse unless reaffirmed, revised, or retired. It was never reaffirmed. The Academy has issued no replacement since, meaning the most heavily criticized circumcision statement it ever published[18] is also, technically, an expired one it has never officially superseded.[19]

In 2024–2025, two members of the task force that wrote it were asked, on the record, whether they'd stand behind it today. Neither would.[19]

Dr. Andrew Freedman, pediatric urologist — 2012 AAP task force

“Maybe the AAP should get out of the [circumcision] business, since it's not really a medical practice. It's only a ‘medical procedure’ in the sense that medical professionals are performing it.”[19]

2022

The rate drops below half CDC / medicine

National hospital data puts newborn circumcision at 49.3% in 2022, down from 54.1% a decade earlier[13] — most American infant boys are now left intact.

The pattern

Misinformation that outlives its correction

Notice what recurs: grand claims of benefit and bad practical advice both eventually get discredited — but rarely all at once, and almost never with an announcement. Sometimes nothing even happens: a position statement just lapses, unrenewed, with no replacement and no verdict either way. What ties these together isn't which direction the correction ran. It's that however it happened, it happened quietly, while the version already absorbed by a generation of parents and doctors carried on regardless.

That's why the bad information keeps moving through families and training lineages long after the institutions that issued it have changed course or simply gone quiet.

For reference: lobotomies (performed on tens of thousands of Americans, with full professional backing) were still being carried out as late as 1967, not some distant historical practice. They were never formally banned; the profession simply abandoned them once the harm became undeniable. This isn't to equate the two, but to note that the medical system can get things horribly wrong sometimes.

A track record of past errors does not automatically make today's pro-circumcision claims wrong. That would be a logical error of its own — "they were wrong before, so they're wrong now" is not a valid argument, and we're not making it.

What the history does establish is narrower and fair: that official confidence on this subject has repeatedly outrun the evidence, that corrections have tended to be silent rather than announced, and that harm-causing advice has been issued by the highest authorities and then quietly withdrawn. That justifies reading current claims critically rather than deferentially: checking the numbers yourself, asking what the absolute risk is when only relative risks are given, noticing when a position has quietly expired.

The takeaway isn't "never trust doctors." It's "trust is earned per claim, not granted per institution." A body that removed a true paragraph and couldn't say why has to earn back the benefit of the doubt — by showing its work, explaining why it doesn't align with other western medical organizations, which is all this site is asking anyone to do.

In context

How other countries compare

The circumcision-rate data behind the corner box that appeared over the timeline above — US, Canada, and UK, every figure sourced. Treat these numbers as a rough idea based on the data that is available, not exact figures. Australia is included below too, for reference, but isn't part of the corner box.

The United States is unusual in having a dense, continuous, hospital-record-based series of newborn circumcision rates going back to 1979 (see above). Other countries were never tracked as consistently, so the picture below is necessarily patchier — a handful of dated points per country rather than a smooth line. Most are hospital or health-records data; a few older figures marked * come from historical estimates or secondary compilations rather than a contemporaneous count, and are included only because they're in the right ballpark of the stronger data around them — see the reference for what kind of source each one actually is. As you scroll through the timeline above, the box in the corner ticks through the year continuously and draws a straight line between each country's two nearest real points to estimate that year's rate — marked when it's landed between two known points rather than on one. It's a linear guess between real data, not a third kind of record.

United States

  • ~10%* — 1880 (estimate)[26]
  • ~30%* — 1930s (estimate)[27]
  • 64.5% — 1979 (national, hospital records)[14]
  • 64.9% — 1981, series peak[14]
  • 55.4% — 2007[14]
  • 54.1% — 2012[13]
  • 49.3% — 2022[13]

CDC hospital-discharge series from 1979 on — the most complete contemporaneous dataset of any country here; the two starred points before it are rough historical estimates, not counted records. (An AMA report also claims a rate near 80% "by the early 1970s," but doesn't cite a source for it and conflicts with the CDC series' own 65% peak a few years later — the same problem as the Laumann self-report figure discussed above, so it's left out here rather than repeated.)

Canada

  • 67.5% — 1971 (Alberta)[20]
  • 47.4%* — 1973 (national, estimate)[28]
  • ~20% — 1996/97 (national)[21]
  • 13.9%* — 2003 (national, estimate)[28]
  • 9.2% — 2005 (national)[21]

Provincial and national hospital-procedure data; the 1971 figure is one province, not a national rate.

United Kingdom

  • ~35%* — 1930s (estimate)[29]
  • ~20% — 1949 (Gairdner's national estimate)[5]
  • ~10%* — 1963 (estimate)[29]
  • ~6%* — 1975 (estimate)[29]
  • Near 0% — today, non-therapeutic infant circumcision[25]

No agency has tracked a UK newborn-rate series with hospital-record precision — even the 1930s–1975 figures are a historian's estimates, not a counted series like the US or Canadian data.

Australia

  • 49% — 1973–74 (national)[22]
  • 39% — 1979–80 (national)[22]
  • 9.8% — 1994 (Western Australia, <6 months)[23]
  • 7.9% — 1999 (Western Australia, <6 months)[23]
  • 12.7% — 2004 (national, Medicare claims)[24]
  • 9.66% — 2015/16 (national, Medicare claims)[24]

Mixes national and Western-Australia-only figures — real regional variation, not a data error, but don't read it as one smooth national line. A widely-circulated 2024 article claims a mid-century Australian peak near 85%, but its own citations don't actually support that number, so it's left out here.

Every figure above is a newborn/infant circumcision rate specifically — not a lifetime adult-prevalence estimate, and not a per-1,000-children procedure count. Those are real, published numbers for these countries too, but they measure something different and would make the rates look artificially comparable if mixed in here; see the references for what was left out and why. Figures marked * are historical estimates or secondary compilations rather than a hospital record or contemporaneous survey — they're included because they're broadly consistent with the stronger data on either side of them, not because they're independently precise.
