Tuli is often called harmless tradition or hygiene. The evidence supports a more cautious view. It is a permanent, non-therapeutic genital surgery, usually done on a Filipino boy in late childhood or adolescence, often under social pressure and before mature consent.
It carries real surgical risk (a 2021 meta-analysis pooled ~3.8% complications requiring treatment), removes specialised tissue, and raises credible — if contested — questions about sensation, sexual function, and psychological distress. Sensitivity and sexual-function findings are associations, not proof; a Filipino PTSD study is a contested source lead, not settled fact.
It does not support claims that circumcision causes cheating or hypersexuality — those are unproven and should not be repeated. The honest conclusion: uncertainty is a reason to wait until the person can decide for himself, not a reason to cut a minor.
In the Philippines, tuli — circumcision — is so common and so expected that it is often treated as a harmless tradition, a matter of hygiene, or a simple step into manhood. A careful look at the evidence supports a more cautious view. Tuli is a permanent, non-therapeutic genital surgery, usually performed on a boy in late childhood or adolescence, often under heavy social pressure and before he can give mature, independent consent. It carries real surgical risk, raises credible questions about psychological distress and sexual sensation, and removes specialised tissue. None of that requires exaggeration — and none of it depends on the false claims that circumcision causes cheating or makes boys hypersexual, which the evidence does not support.
This article separates what is well supported from what is disputed, and both from what is simply unproven. Our position is not that every circumcised man is harmed or that every tuli was traumatic. It is narrower and, we think, harder to dismiss: "harmless tradition" is not an evidence-based description of what tuli is.
Plain-English summary
Tuli is often framed as tradition, hygiene, or masculinity. The evidence supports something more careful: boys can be pressured into a permanent genital surgery before they can meaningfully consent; the surgery carries real risks; some research raises concerns about trauma and about sensation and sexual function; and a number of dramatic claims circulating online are not supported and should not be repeated as fact. Uncertainty here is not a reason to cut a minor — it is a reason to wait until the person can decide for himself.
What the evidence says
Tuli as a puberty and masculinity ritual
In the Philippines circumcision is near-universal and is usually done not in infancy but in late childhood or early adolescence: a community survey found roughly 52% of boys are cut at ages 10–14 (and about 42% younger), and it is widely framed as a rite of passage toward manhood. The strongest driver is social, not medical. In that survey — the primary source behind the WHO/UNAIDS figures — about two-thirds of boys chose to be circumcised "to avoid being uncircumcised," and 41% said it was "part of the tradition," while medical reasons were far less common. The fear of being labelled supót (uncircumcised) — used here only as a description of a stigma, never as an insult — is a recurring reason boys give. A practice can be sincerely meant, widespread, and culturally important and still deserve the same questions we would ask of any surgery on a child.
Free adult consent is not the same as adolescent social pressure
There is a meaningful ethical difference between an adult who freely chooses circumcision for himself and a twelve-year-old who agrees because everyone else is doing it and he does not want to be teased. International child-rights principles hold that a child's own views should carry weight, in line with his age and maturity, in decisions that affect his body. When the main reason to proceed is avoiding shame, the "yes" is doing less work than it appears to. This is a consent problem, not a claim about any medical outcome.
The anatomy: the prepuce is specialised tissue
The foreskin is not spare skin. Anatomical work describes the prepuce as structured, innervated, vascular mucosal tissue with mechanical and protective roles for the glans. Recognising this does not, by itself, prove any particular effect on adult sexual satisfaction — that is a separate and contested question — but it does mean that circumcision removes functional tissue rather than merely tidying an "extra" flap.
Physical complications are real, and rates depend on conditions
Circumcision is surgery, and surgery has complications: pain, bleeding, infection, scarring, problems with healing, meatal complications, and — rarely — severe outcomes. A large 2021 systematic review and meta-analysis (351 studies, roughly four million participants) pooled a complication risk requiring treatment of about 3.8% for procedures done by health-care professionals. That figure should be read carefully: complication rates vary a great deal with the boy's age, the method used, the operator's training, sterility, follow-up, and how "complication" is even defined. Procedures done quickly, in crowded settings, or by untrained practitioners are not represented by the best-case numbers.
Psychological distress: a signal that still needs verification
The experience of tuli ranges from a calm, well-managed clinical procedure to a frightening, painful one. One retrospective Filipino cohort (Boyle & Ramos, 2019) reported that 69% of ritually-cut boys met DSM-IV criteria for a PTSD diagnosis and 51% of medically-cut boys showed PTSD-like symptoms. We include this as a source lead, not an established fact: it is a single retrospective, self-report study with no intact control group (the authors' own stated limitation), drawn from one province and roughly twenty-year-old thesis data, by an advocacy-aligned author, in a journal since dropped from Scopus — and it has been independently critiqued. It needs replication and scrutiny before anyone treats those percentages as settled. The defensible takeaway is narrower — fear, pain, and lack of consent are avoidable risk factors worth taking seriously — not that tuli routinely causes PTSD.
Sexual function: contested, and honestly so
Here the evidence is genuinely mixed. Some studies report reduced sensitivity or more sexual difficulty after circumcision. A sensitivity-mapping study (Sorrells et al., 2007) reported that the circumcised glans is less sensitive to fine touch and that several sites removed by circumcision are among the most sensitive. A large self-report cohort (Bronselaer et al., 2013) reported reduced genital sensitivity. A Danish national survey (Frisch et al., 2011) found circumcision associated with frequent orgasm difficulties in men and with several partner-reported difficulties in women. Every one of these findings must be stated as reported or associated with — not proven — because they are cross-sectional or self-report designs, several have published rebuttals, and other reviews conclude there is little or no adverse effect. Association is not causation.
Chronic glans exposure: describe it precisely
Circumcision permanently changes the covering and exposure environment of the glans and removes tissue that normally protects it; keratinisation (toughening) of the exposed glans over time is described in the literature. What the evidence does not support is any leap from "the glans is more exposed" to claims about libido, infidelity, or compulsive sexual behaviour. Those behavioural claims are unproven and should not be made.
What is disputed
- Some medical reviews and pro-circumcision authors conclude circumcision has little or no adverse effect on sexual function.
- Other studies report reduced sensitivity, orgasm difficulty, discomfort, or partner-reported sexual difficulties.
- The disagreement is driven by study design, cultural context, age at circumcision, self-report bias, and what is being measured — anatomy, sensation, satisfaction, orgasm, pain, or a partner's experience are not the same outcome.
AntiCirc's reading of this disagreement is simple: uncertainty is not a reason to cut a minor. Uncertainty is a reason to wait until the person whose body it is can weigh these disputed questions and decide for himself.
What this does not prove
- This does not prove circumcision causes cheating.
- This does not prove circumcised men are immoral, sexually uncontrolled, or unsafe partners.
- This does not prove every circumcised man has sexual dysfunction.
- This does not prove every tuli was traumatic.
- This does not prove all medical circumcisions are botched.
- It does show that "harmless tradition" is not an evidence-based framing.
Country relevance: the Philippines
These questions are not abstract in the Philippines, where tuli is close to universal, is timed to the school summer break, and is promoted through free mass-circumcision drives ("Operation Tuli"). Public-health messaging that treats tuli as routine hygiene sits uneasily with the facts above: the procedure is not medically necessary for a healthy boy, the consent is often shaped by stigma rather than free choice, and "free" says nothing about whether a given drive is safe or consenting.
