What Happens If Circumcision Goes Wrong?

Circumcision complications range from minor bleeding that resolves with pressure to catastrophic injuries requiring reconstructive surgery. Overall complication rates in medical settings sit below one percent for serious events, though the definition of “complication” varies widely across studies. A systematic review catalogued 47 distinct complications reported in the medical literature, and how quickly a problem is caught and managed often determines whether the outcome is a brief scare or a lasting one.

How Common Are Complications, and What Counts as One

The numbers depend heavily on who is doing the counting and what they include. A large U.S. study covering circumcisions performed between 2001 and 2010 found the total adverse-event rate was slightly under half a percent, with the most frequent coded event being “repair of incomplete circumcision.” Rates of potentially serious events like stricture were far rarer, measured in single digits per million procedures.¹ That same dataset revealed a striking age effect: boys circumcised between ages one and nine had roughly twenty times the complication rate of those circumcised in infancy, and boys ten and older had about ten times the rate.

A cohort study comparing neonates and older children found a combined complication rate of about 13%, but this included minor issues like meatal web and cosmetically unsatisfactory results that many other studies would not flag. In that cohort, neonates actually had a higher rate than older children, driven by meatal stenosis, meatal web, and incomplete foreskin removal.² The seeming contradiction with the U.S. data reflects different populations, follow-up lengths, and definitions. A systematic review of 78 articles compiled a list of 47 specific complications that have been reported, from the mundane to the devastating.³

Bleeding and Early Wound Problems

Bleeding is the most common immediate complication. In emergency-department presentations after circumcision, it was the primary reason for the visit in over half of cases, followed by pain, swelling, and redness.⁴ Most post-circumcision bleeding is manageable. In a study of 90 infants who came to the emergency room after ritual circumcision with bleeding, about a third needed no treatment at all on arrival, and roughly half were managed with a hemostatic dressing. Surgical intervention was needed in about 12% of those cases, and two infants required blood transfusions.⁵

The key factor was whether bleeding was still active when the child arrived at the ER. Among those with active bleeding, nearly a quarter required surgery, compared with just 2% of those whose bleeding had already stopped. For parents, the practical lesson is straightforward: apply firm, direct pressure, and get medical attention quickly if bleeding does not slow down within several minutes.

Infection, Including Life-Threatening Cases

Wound infections after circumcision in a clinical setting are uncommon and usually mild, treatable with local wound care or a course of antibiotics. The danger comes from rare but fast-moving infections. Necrotizing fasciitis, the aggressive tissue-destroying infection sometimes called “flesh-eating disease,” has been reported in infants after circumcision, including after use of the Plastibell device.⁶ A related condition, Fournier’s gangrene, involves necrotizing infection spreading to the genital and perineal area. Case reports have linked it to circumcisions performed outside hospital settings, where sterility cannot be ensured.⁷

Signs that a post-circumcision wound has become seriously infected include rapidly spreading redness or darkening of the skin, fever, swelling well beyond the wound area, and a foul smell. These need emergency evaluation, not a wait-and-see approach.

Glans Amputation and Severe Tissue Injury

The most alarming complication is partial or total amputation of the glans (the head of the penis). Published case reports describe it happening with various devices and in various settings. In one reported case, an experienced religious practitioner who had performed thousands of circumcisions using a Mogen clamp accidentally cut proximal to the clamp, amputating the entire glans of a neonate.⁸ Another case involved a four-year-old boy who lost his glans during the procedure.⁹

If the amputated tissue is recovered and the child reaches a surgical team quickly, reimplantation can sometimes succeed. When it does not, or when the tissue is not recoverable, reconstructive surgery becomes the path forward. In a series of twelve patients who lost between 65% and 95% of their penile shaft skin, including two with partial glans loss, surgeons used full-thickness skin grafts or tissue expanders to rebuild coverage. The injuries in that group were most often traced to the Mogen clamp, though the Gomco clamp, Plastibell, and electrocautery were also implicated.¹⁰ Newer techniques using oral mucosa grafts to resurface the glans have shown promising results, with satisfactory cosmetic outcomes and urethral patency in the majority of patients, though graft loss remained a risk in some cases.¹¹

Device-Related Complications

Three devices dominate circumcision practice: the Gomco clamp, the Mogen clamp, and the Plastibell. Each carries its own risk profile. The Plastibell is a plastic ring that stays on the penis after surgery and is supposed to fall off on its own as the tissue heals, usually within a week or so. When it does not, things get complicated.

In a study of about 1,000 Plastibell circumcisions, the retained ring was the single most common complication, occurring in roughly 5% of cases. The stuck ring caused constriction and swelling of the glans and had to be cut off manually.¹² Worse outcomes occur when the ring migrates proximally (slides down the shaft). In a review of cases where the Plastibell slipped, all infants showed signs of painful urination, nearly three-quarters had extensive skin loss on the penis or glans, about 40% developed urethrocutaneous fistulae (an abnormal opening between the urethra and the skin), about a quarter developed sepsis, and roughly one in six had partial death of glans tissue.¹³

Too Much or Too Little Skin Removed

Getting the amount of tissue removal right is one of the hardest parts of the procedure. Taking too much penile shaft skin can leave the remaining skin painfully tight during erections later in life and may require skin-graft reconstruction.¹⁴ In one large study from Iran, excessive skin removal was found in about 1.3% of circumcised boys.¹⁵

Removing too little skin creates its own set of problems. When enough inner foreskin is left behind, the remnant can scar and readhere to the glans, producing secondary phimosis, which is essentially a return to the tight, non-retractable state the procedure was meant to prevent. One study found that secondary phimosis was more common when circumcision was done at a younger age and when thermal cautery was used rather than a scalpel blade.¹⁶ In the U.S. data, the single most frequently coded adverse event was “repair of incomplete circumcision,” suggesting that under-resection is far more common than over-resection.¹

Meatal Stenosis and Urinary Stream Problems

One of the more common late complications is meatal stenosis, a narrowing of the urethral opening at the tip of the penis. After circumcision, the meatus loses the protective coverage of the foreskin and becomes exposed to friction from diapers and clothing. Over time, irritation can cause scarring that narrows the opening. Meatal stenosis was the most common late complication in both age groups in the neonatal-versus-children cohort study, affecting about 4% of neonates and about 2% of older children.²

Interestingly, what looks like meatal stenosis is not always true narrowing. Research has found that many boys diagnosed with a pinpoint-appearing meatus actually have a meatal web, a thin tissue bridge on the underside of the opening that deflects the urine stream upward without truly blocking flow. In those cases, the urethra can still be calibrated to a normal size, and a minor outpatient procedure to snip the web resolves the problem.¹⁷ True meatal stenosis, where fibrosis or scarring has genuinely narrowed the opening, is defined by visible loss of the meatus’s normal elliptical shape and confirmed narrowing.¹⁸ The distinction matters because the treatment differs: a web can be dealt with quickly, while true stenosis may need a more involved meatoplasty.

Adhesions, Skin Bridges, and Buried Penis

After the wound heals, the raw inner surface of the remaining skin can stick to the glans, forming adhesions. These are among the most common post-circumcision findings. In one study, adhesions were circumferential (wrapping most of the way around) in over 80% of affected patients. About two-thirds of families initially chose a home-care approach involving gentle retraction, but only about a third of those saw the adhesions resolve after six months. Most families who started with home care eventually opted for an in-office lysis procedure.¹⁹ Success with conservative management depended on how extensive the adhesions were: mild ones covering less than a quarter of the glans had the best chance of resolving on their own.

If adhesions are left long enough, they can mature into firmer skin bridges, actual bands of tissue connecting the shaft skin to the glans with a visible tunnel underneath. A study of 95 patients with glanular-preputial adhesions found that simple fibrinous adhesions (in about 58% of cases) could be managed medically, while well-formed skin bridges (the remaining 42%) required surgical adhesiolysis.²⁰

Buried penis is a condition in which the penile shaft retracts beneath the surrounding skin, leaving little or no visible shaft. It can occur after circumcision when scar contracture pulls the skin forward, particularly in infants with a prominent suprapubic fat pad. One case series found buried penis in 100% of affected patients under one year old, dropping to about 32% in the one-to-three age range, and about 7% over age three, suggesting that many mild cases self-correct as children grow and the fat pad recedes.²¹ Persistent cases can require surgical correction to free the shaft and prevent further adhesion formation.

Where and By Whom It Is Done Matters Enormously

The single biggest risk factor for a bad outcome is the setting in which the circumcision takes place and the training of the person performing it. A systematic review found that traditional circumcision performed as a rite of passage carries substantially greater risks and more severe complications than medical circumcision or traditional circumcision of neonates.²² A comparative study looking at circumcisions done in hospitals versus those done by unlicensed traditional practitioners found that every complication parameter was higher in the out-of-hospital group, sometimes dramatically so.²³

This does not mean hospital-based circumcisions are risk-free. The glans amputation case mentioned earlier involved an experienced practitioner. But sterile conditions, proper instruments, trained personnel, and immediate access to emergency care reduce both the likelihood and the severity of complications. For families considering circumcision, the credentials and setting of the provider are the most controllable variables.

Anesthesia Reactions

Circumcision is sometimes performed with local anesthesia, such as a dorsal penile nerve block or topical lidocaine cream. Serious reactions are rare, but they exist. One case report described an infant who developed generalized tonic-clonic seizures and a diffuse skin rash after lidocaine injection, consistent with systemic local-anesthetic toxicity.²⁴ A network meta-analysis of local anesthetic techniques for neonatal circumcision found that, across the trials analyzed, no cases of systemic toxicity, anaphylaxis, or ischemia were reported, and methemoglobin levels after EMLA cream were either slightly elevated or statistically similar to controls.²⁵ The takeaway is that while individual case reports of toxicity exist, clinical-trial data suggest it is genuinely uncommon when dosing guidelines are followed.

Revision Surgery for Unsatisfactory Results

Not all complications require major reconstruction. Many men and boys who have an unsatisfactory circumcision end up needing a relatively straightforward revision. In one case series of adults seeking revision, the most common complaints were scar hypertrophy (thickened, raised scarring), scar wrinkling, and incomplete circumcision. Sleeve resection to remove the scar and complete the circumcision produced a good aesthetic and functional result in 96% of patients on the first revision attempt.²⁶ Two patients in that series needed a second revision, and two had partial wound gaping that healed with daily dressing.

This is worth knowing because many families and men assume that a botched circumcision is unfixable. For cosmetic dissatisfaction, scarring, and incomplete removal, corrective surgery is usually successful. The more severe injuries involving significant tissue loss or urethral damage require specialized pediatric urological reconstruction, but even those techniques continue to improve.

Functional and Sensitivity Changes

Beyond the acute surgical risks, a question many people have is whether a circumcision that “goes wrong” in a subtler way, removing tissue that affects sexual function, counts as a complication. A large cohort study found that circumcised men reported decreased sexual pleasure at the glans, lower orgasm intensity, and more effort required to reach orgasm compared to uncircumcised men. They also reported higher rates of unusual sensations like burning, prickling, and numbness.²⁷ A qualitative study of men and their partners after voluntary adult circumcision found similar reports: both men and women described decreased sensitivity and longer time to orgasm, which some viewed positively (helping with premature ejaculation) while others found it worsened erectile difficulties.²⁸

These findings remain contested in the medical literature. Other large studies, particularly randomized trials of adult circumcision in Africa, have reported no significant difference in sexual satisfaction. The honest read is that some men notice reduced sensitivity after circumcision and some do not, and the science has not fully sorted out why. What is clear is that complications involving nerve damage, excessive tissue removal, or painful scarring make functional problems more likely than an otherwise uneventful procedure.

The Legal Side of Circumcision Complications

When things go seriously wrong, families sometimes pursue litigation. A review of U.S. legal databases identified 77 unique circumcision-related cases. The most common basis for a lawsuit was negligent surgical performance, accounting for about half of all cases. The most frequently cited complications in those lawsuits were aesthetic dissatisfaction, pain, impaired sexual function, and surgical trauma. Most patients were minors both at the time of the circumcision and at the time of the lawsuit. When physicians prevailed, they won about 59% of the time, but when verdicts went against them, the median payout was $175,000.²⁹

An analysis of supreme court decisions in Turkey found a similar pattern, with negligence as the leading reason for malpractice claims in circumcision cases, followed by carelessness and faulty surgical technique.³⁰ One notable finding from the U.S. data: lawsuits based on inadequate informed consent were significantly more likely to be decided in the physician’s favor than lawsuits based on negligent surgical performance. In practical terms, this means that documentation of risks before the procedure protects the physician legally but does not protect the patient physically.

Psychological Dimensions

A less-discussed dimension of circumcision complications involves psychological effects. A study comparing neonatally circumcised men with uncircumcised men found that the circumcised group reported higher levels of attachment avoidance and anxiety, lower emotional stability, and higher stress levels.³¹ The effect sizes were small, and the study cannot establish causation. It is also worth noting this research compared routine circumcision to no circumcision, not botched procedures to successful ones. For men who have experienced a genuinely traumatic complication, the psychological burden is likely compounded. Support groups and specialized counseling exist for men dealing with distress related to circumcision outcomes, though awareness of these resources remains low.

The broader point for families weighing the decision is that complications are not just physical events. A boy who grows up with visible scarring, needs repeated corrective procedures, or experiences functional difficulties may carry psychological effects well into adulthood, and those effects deserve consideration alongside the surgical risk statistics.
