Anesthesia is recommended for every circumcision, but the type used depends on the patient’s age and the clinical setting. For newborns, the standard approach is a local anesthetic injection, sometimes combined with a numbing cream and comfort measures like a sucrose pacifier. Older children and adults also receive local anesthesia in most cases, though general anesthesia is occasionally used for young children who cannot hold still. Despite clear professional guidelines, a surprising number of circumcisions worldwide are still performed with inadequate pain relief or none at all.
What Professional Guidelines Say
The American Academy of Pediatrics states plainly that adequate analgesia should be provided whenever newborn circumcision is performed. Its 2012 policy report specifies that the procedure should use effective pain management and that nonpharmacologic techniques alone, like positioning or sugar pacifiers, are not enough to prevent the pain of circumcision and should only be used as add-ons to actual anesthesia.1Pediatrics. Male Circumcision This was a significant shift from earlier decades, when many physicians believed newborns did not feel pain in a meaningful way, or that the procedure was too brief to justify anesthesia.
The turning point came from research in the late 1980s and 1990s. A landmark study published in JAMA showed that dorsal penile nerve block safely and effectively reduced both behavioral distress and the stress hormone cortisol during neonatal circumcision.2JAMA. Local Anesthesia for Neonatal Circumcision: Effects on Distress and Cortisol Response Meanwhile, research by Taddio and colleagues found that babies circumcised without any pain relief showed heightened pain responses months later during routine vaccinations, compared to uncircumcised infants or those who received a topical anesthetic cream for the procedure.3The Lancet. Effect of neonatal circumcision on pain response during subsequent routine vaccination That finding helped demolish the old notion that newborns would not remember or be affected by procedural pain.
The Main Types of Local Anesthesia for Newborns
Three local anesthesia options dominate neonatal circumcision: dorsal penile nerve block (DPNB), ring block, and topical numbing cream. Each works differently and has distinct strengths.
A dorsal penile nerve block involves injecting a small amount of lidocaine near the base of the penis to numb the two main nerve bundles that supply sensation to the foreskin. It is the most commonly used technique among physicians who provide anesthesia for circumcision.4Pediatrics. Circumcision Practice Patterns in the United States A ring block takes a slightly different approach, injecting anesthetic in a ring around the shaft of the penis. In a randomized trial comparing the two injected techniques to topical cream and no treatment, both DPNB and ring block produced significantly less crying and lower heart rates during and after the procedure compared to untreated infants. The ring block provided more consistent pain control across all stages of the surgery, while the DPNB and the topical cream were less effective during the initial foreskin separation and incision.5PubMed. Comparison of ring block, dorsal penile nerve block, and topical anesthesia for neonatal circumcision: a randomized controlled trial
Topical anesthesia, usually a lidocaine-prilocaine cream applied under a dressing for about an hour before surgery, offers a needle-free option. It does reduce pain compared to nothing: in one trial published in the New England Journal of Medicine, babies who received the cream cried less than half as much as those given a placebo, and their heart rate increases were about 10 beats per minute lower.6PubMed. Efficacy and safety of lidocaine-prilocaine cream for pain during circumcision A Cochrane review pooling multiple studies confirmed a heart rate increase of 12 to 27 fewer beats per minute in cream-treated groups versus placebo.7Cochrane Database of Systematic Reviews. Lidocaine-prilocaine cream for analgesia during circumcision in newborn boys However, head-to-head trials show the cream provides weaker pain control than an injected block. One study found significantly higher pain scores and larger heart rate jumps in babies receiving topical cream compared to DPNB during the cutting and tying steps.8PubMed Central. A comparison of anesthetic efficacy between dorsal penile nerve block (DPNB) with lidocaine and eutectic mixture of local anesthetics (EMLA) cream during neonatal circumcision
Because no single method blocks all the pain perfectly, some practitioners combine them. A randomized trial found that applying the topical cream before performing a DPNB had favorable effects on anesthesia quality and surgical ease, suggesting the combination is safe and offers added benefit.9Turkish Journal of Pediatric Surgery. Analgesic efficacy of using topical anesthetic before dorsal penile nerve block in infant circumcision: A randomized-controlled study Another study combining DPNB with topical cream and other comfort measures found that infants spent only about 18% of the procedure crying, compared to 40% with a less comprehensive approach.10Archives of Pediatrics & Adolescent Medicine. Combined Analgesia and Local Anesthesia to Minimize Pain During Circumcision
The Role of Sucrose Pacifiers and Other Comfort Measures
You will sometimes hear that giving a baby a sugar-dipped pacifier during circumcision helps with pain. It does, but only modestly. In one trial, control infants who received no treatment cried about 67% of the time during the procedure. A water-moistened pacifier brought that down to 49%, and a sucrose-flavored pacifier reduced it further to 31%.11Pediatrics. Sucrose as an Analgesic for Newborn Infants Sucrose also provided statistically significant relief compared to no treatment throughout most of the procedure in another trial, though the DPNB in the same study reduced heart rate elevation by nearly three times as much as sucrose did.12PubMed. Neonatal circumcision. Randomized trial of a sucrose pacifier for pain control
The takeaway is that sucrose pacifiers, swaddling, skin-to-skin contact, and white noise genuinely improve infant comfort, but they are not substitutes for anesthesia. The AAP’s position is that these measures should accompany pharmaceutical pain management, not replace it.1Pediatrics. Male Circumcision
How Pain Management Works for Older Children and Adults
When circumcision is performed on older boys or men, local anesthesia remains the standard first-line approach. Adults typically receive a penile nerve block, a ring block, or a combination of the two. A study of 250 adult patients compared five different injection-based techniques and found that a subcutaneous ring block or a dorsal nerve block combined with frenulum infiltration provided reliable surgical anesthesia with low complication rates and extended post-operative pain relief.13PubMed. Regional anaesthesia for circumcision in adults: a comparative study
A more recent retrospective study of adult circumcisions under DPNB alone reported that about two-thirds of patients experienced no procedural pain at all, and none required conversion to general anesthesia. Roughly 87% said they were satisfied with the local anesthetic’s pain control.14PubMed Central. Efficiency and Patient Satisfaction of Local Anesthesia Use in Surgical Circumcision in Adults-A Retrospective Cohort Study For young children who cannot cooperate with a local injection, general anesthesia or sedation is sometimes used. The decision usually depends on the child’s age, anxiety level, and the practitioner’s judgment.
In resource-limited settings where traditional injection equipment is scarce, needle-free jet injection devices have been tested. One study using a jet injector to deliver lidocaine found that over 85% of men did not require any supplemental anesthesia, and the anesthetic took effect in about 45 seconds.15PubMed. No-needle local anesthesia for adult male circumcision This kind of innovation matters in regions where large-scale voluntary circumcision programs run in settings with limited supplies.
Why Many Circumcisions Still Happen Without Proper Pain Relief
Despite the evidence, a substantial gap persists between guidelines and practice. A survey of U.S. physicians found that only 45% of those performing circumcisions used anesthesia at the time of the study. The rates varied dramatically by specialty: 71% of pediatricians used it, compared to 56% of family practitioners and just 25% of obstetricians. Among those who skipped anesthesia, the most common reason cited was concern over adverse drug effects (54%), followed by the belief that the procedure simply did not warrant it (44%).4Pediatrics. Circumcision Practice Patterns in the United States
Those numbers predate the AAP’s strongest statements on the issue and have likely improved, but incomplete anesthesia use remains a concern globally. A review noted that many neonatal circumcisions worldwide are still performed without anesthesia, particularly in traditional or religious settings where the procedure is carried out by non-physician practitioners.16PubMed. Anesthesia for ritual circumcision in neonates In Jewish ritual circumcision (bris), traditionally performed on the eighth day of life by a mohel, anesthetic use varies by practitioner and community. Muslim circumcisions are more flexible in timing and are more often performed in clinical settings with standard anesthesia, though this also varies by region.
After the Procedure: Managing Post-Operative Pain
Anesthesia during circumcision addresses the surgical pain, but discomfort continues afterward as the local block wears off. Post-operative pain management is a separate challenge that many parents understandably worry about.
Acetaminophen (the active ingredient in infant Tylenol) is widely given, but its track record is mixed. One study found that acetaminophen did not meaningfully reduce pain during or immediately after the procedure, though it seemed to offer some benefit in the hours following.17Pediatrics. Acetaminophen Analgesia in Neonatal Circumcision: The Effect on Pain A quality improvement project that implemented a standardized protocol, including pre-circumcision acetaminophen, white noise during the procedure, structured pain assessment, and acetaminophen or comfort measures during recovery, showed a significant drop in neonatal pain scores, from about 3.1 down to about 1.1 on a standardized scale.18PubMed. Implementing an Evidence-Based Neonatal Circumcision Pain Management Protocol: A Quality Improvement Initiative The lesson is that post-operative care works best when it combines multiple approaches rather than relying on a single medication.
Risks of the Anesthesia Itself
One reason some practitioners historically avoided anesthesia was concern about complications from the drugs themselves. Those concerns are not baseless, but the risks are small and manageable when dosing guidelines are followed.
The most discussed risk with topical lidocaine-prilocaine cream is methemoglobinemia, a condition where the blood cannot carry oxygen efficiently. It is rare but can be serious in newborns, whose immature enzyme systems are less able to cope with the chemical changes the drugs cause. Case reports document it occurring after excessive or prolonged application: one involved a six-week-old who developed the condition after the cream was left on for 15 hours, far longer than recommended.19PubMed Central. Acquired Methemoglobinemia in an Infant: Consequence of Prolonged Application of Eutectic Mixture of Local Anesthetics (EMLA) Cream for Spontaneous Abscess Drainage Another case involved a 12-day-old who developed severe methemoglobinemia (a blood level of nearly 50%, versus the normal below 1.5%) after receiving both injected lidocaine and topical cream for circumcision.20PubMed Central. A 12-Day-Old Boy with Methemoglobinemia After Circumcision with Local Anesthesia (Lidocaine/Prilocaine) The AAP recommends using penile nerve block rather than topical cream for low-birth-weight infants, who face a higher risk of skin irritation from the cream.1Pediatrics. Male Circumcision
For injected blocks, the main risks are minor: local bruising or hematoma occurs in a small percentage of cases (about 2.6% in one large series), along with mild swelling.21PubMed. Circumcision in children with penile block alone Local anesthetic systemic toxicity, where too much drug enters the bloodstream, is extremely rare but more dangerous. It can cause seizures or cardiac arrest. A case report described a two-month-old former premature infant who developed ventricular fibrillation after a caudal block with bupivacaine during combined hernia repair and circumcision, illustrating that the risk is highest in very young or premature babies with immature liver function.22PubMed Central. Local Anesthetic Systemic Toxicity in an Infant Following a Caudal Block: A Case Report and Review of Literature These cases are uncommon precisely because the doses used for penile blocks are small, and the technique is straightforward for trained practitioners.
Does the Circumcision Device Matter for Pain?
Circumcision can be performed using several devices, most commonly the Gomco clamp, the Mogen clamp, and the Plastibell device. Parents sometimes wonder whether the choice of device affects how much pain their baby experiences. The answer is yes, at least somewhat. A study comparing all three found statistically significant differences in subjective pain reports between them, though complication rates and emergency department return rates did not differ.23PubMed. Comparative Analysis of Postoperative Outcomes Following Various Neonatal Circumcision Techniques: Mogen Clamp, Gomco Clamp, and Plastibell Device
One important practical factor is speed. The Mogen clamp allows a much faster procedure, averaging about 81 seconds compared to about 209 seconds for the Gomco. In a trial comparing the two clamps with and without DPNB, the Mogen clamp was associated with less crying and smaller changes in heart rate and breathing rate. Anesthesia use independently reduced crying time and oxygen saturation changes regardless of which clamp was chosen. The best outcome was the combination: over half of babies circumcised with the Mogen clamp and a dorsal penile nerve block did not cry at all during the procedure.24Pediatrics. A Comparison of the Mogen and Gomco Clamps in Combination With Dorsal Penile Nerve Block in Minimizing the Pain of Neonatal Circumcision
What Parents Should Ask Before the Procedure
Research consistently shows that parents often lack access to clear, accurate information about circumcision. A study of parental decision-making found that personal and cultural beliefs played an equal or larger role than medical information in the decision, and some parents noted that good information about risks and benefits was hard to find.25PubMed Central. Parental Decision Making in Male Circumcision Another study found that satisfaction rates were significantly higher among parents who received thorough pre-procedure counseling from a healthcare provider.26PubMed.

If you are considering circumcision for your child, the anesthesia conversation is one of the most concrete things you can ask about before consenting. Useful questions include what type of pain relief will be used and why, whether the practitioner combines techniques, how post-operative pain will be managed at home, and what signs of a complication to watch for. If a provider says they do not use any anesthesia, that is a red flag worth pushing back on. The evidence is clear that circumcision causes significant pain and that safe, effective options exist to reduce it.
Circumcision Pain and Longer-Term Effects
The Taddio vaccination study mentioned earlier raised an important question: does the pain of circumcision leave a lasting imprint? That study found a graded pattern. Uncircumcised infants showed the lowest pain responses during later vaccination, followed by those circumcised with topical anesthetic, followed by those circumcised with a placebo cream who showed the highest pain scores.3The Lancet. Effect of neonatal circumcision on pain response during subsequent routine vaccination The implication was that even brief, intense pain during the neonatal period can alter pain processing in the months afterward, and that anesthesia partially but not completely buffered this effect.
Whether neonatal circumcision produces measurable psychological effects years later is far more contentious and much harder to study. One survey-based study reported small statistical differences between circumcised and uncircumcised men on measures of attachment style and emotional stability, with circumcised men scoring slightly higher on avoidance and anxiety in relationships.27PubMed Central. Neonatal male circumcision is associated with altered adult socio-affective processing But the effect sizes were tiny, the study was cross-sectional and relied on self-report, and it could not determine whether circumcision itself, the pain of the procedure, cultural factors, or something else entirely drove the associations. No differences were found in empathy, trust, or the “Big Five” personality traits. This is an area where a single study gets cited far beyond what its design can support, and the honest assessment is that the evidence for lasting adult psychological effects is thin and inconclusive. What is better established is the short-term finding: neonatal pain can heighten subsequent pain sensitivity, and anesthesia during circumcision reduces that effect.
