Facts and Myths of Circumcision: Separating Truth from Misconception

Circumcision, the surgical removal of the foreskin from the penis, sparks curiosity and debate worldwide. Whether driven by medical, cultural, or religious reasons, it’s a procedure surrounded by questions and misconceptions. Globally, about 30-40% of males are circumcised, with rates as high as 55-60% in the U.S. and below 20% in Europe. Despite its prevalence, circumcision is surrounded by myths that cloud informed decision-making. This article distinguishes fact from fiction, examining the medical, cultural, and ethical aspects to help parents, individuals, and curious readers navigate this complex topic.

Myth # 1: Circumcision is only performed on children

This is a myth. While circumcision is commonly performed on infants, often for religious reasons, in Singapore, it can also be performed on adults for various reasons.

Medical reasons include phimosis (tight foreskin causing urinary or sexual issues), paraphimosis, balanitis (inflammation), or recurrent UTIs.

Religious reasons apply to adults converting to Judaism or Islam, where circumcision is a faith requirement. For example, immigrants to Israel from non-circumcising countries often undergo adult circumcision for religious integration.
Cultural reasons include peer pressure or social norms, as seen in South Korea, where ~85% of men aged 16-39 are circumcised, often around age 12, due to perceived modernity or hygiene.

Statistics on adult circumcision are limited, but a 2017-2018 Danish survey found 7% of men aged 15-89 were circumcised, with 5% for medical/other reasons and 2% for religious/traditional reasons. In the U.S., adult circumcision is less common, with most procedures occurring neonatally, but some men seek it for cosmetic or health reasons.

Myth # 2: Circumcision is only performed for religious reasons

This is a myth. While circumcision is significant in religions like Judaism and Islam, it is also performed for medical reasons.

Medical reasons for circumcision include:

• Phimosis: This is a medical condition that affects 1-5% of uncircumcised males, where the foreskin cannot retract, causing pain or infections
• Paraphimosis: This is a medical emergency where the foreskin is trapped beneath the glans penis which can lead to strangulation of the glans and painful vascular compromise, distal venous engorgement, edema, and even necrosis.
• Recurrent urinary tract infection: Recurrent UTIs can cause renal dysfunction by repeated bacterial infections, leading to kidney inflammation and scarring (pyelonephritis), especially with vesicoureteral reflux. Circumcision can reduce the risk of urinary tract infection in boys by limiting bacterial colonization under the foreskin, therefore, limiting the risk of chronic kidney disease.
• Reduction in the risk of sexually transmitted infections (STIs): Circumcision reduces the risk of STIs by removing the foreskin, which can harbor bacteria and viruses. The moist environment under the foreskin facilitates pathogen survival and entry through microtears during sexual activity.

Myth # 3: Circumcision eliminates the need for STI protection

This is a myth. Circumcision involves the removal of the foreskin, which can trap pathogens and is susceptible to small tears, lowering the risk of certain STIs. However, it doesn’t fully prevent STI transmission, as infections can still spread through exposed genital areas, bodily fluids, or other pathways. As circumcision does not eliminate the risk of STIs, safe sex practices remain essential. Some examples of safe sex practices include:

• Condom Use: Correct and consistent use of male or female condoms during vaginal, anal, or oral sex significantly lowers STI transmission risk (e.g., 80–95% reduction for HIV).
• Dental Dams: Using dental dams or cut latex condoms for oral sex to prevent STI transmission.
• Regular STI Testing: Routine testing for STIs, especially for sexually active individuals or those with multiple partners, to detect and treat infections early.
• Mutual Monogamy: Engaging in a committed relationship where both partners are tested and confirmed STI-free.
• HPV Vaccination: Getting vaccinated against human papillomavirus (HPV) to prevent HPV-related infections and cancers.
• Pre-Exposure Prophylaxis (PrEP): Taking daily medication to prevent HIV infection for high-risk individuals.
• Limiting Partners: Reducing the number of sexual partners to lower exposure to potential STIs.
• Open Communication: Discussing STI status, testing history, and safe sex preferences with partners before sexual activity.

Myth # 4: General anesthesia is always required for adult circumcision

This is a myth. While conventional circumcision often uses general anesthesia for comfort, modern techniques like Shang Ring and ZSR stapler circumcision are safely performed under local anesthesia with minimal pain. In general, device-based circumcision techniques such as the Shang Ring and ZSR stapler have been shown to have shorter operative times (5–15 vs. 30–60 minutes) and lower pain scores (2–3 vs. 4–5/10) than conventional methods.

Shang Ring circumcision uses a clamping device and takes 5–10 minutes to be performed. It is done under local anesthesia, and a 2013 study showed 99% success with pain scores of 2–3/10.

The ZSR Stapler circumcision can cut and seal simultaneously with staples, therefore, it takes 5–15 minutes to be performed under local anesthesia. A 2018 study reported 95% of patients had mild/no pain (<3/10).

Myth # 5: Circumcision significantly reduces sexual pleasure

The belief that circumcision greatly diminishes sexual pleasure is a myth, as evidence on its impact is mixed and inconclusive. While some studies suggest the foreskin enhances sensitivity due to its nerve endings, comprehensive reviews, including a 2013 meta-analysis, found no significant differences in sexual satisfaction, orgasm quality, or erectile function between circumcised and uncircumcised men. A 2013 randomized controlled trial in South Africa (Journal of Sexual Medicine), involving 1,388 men and their female partners, further showed that 61.6% of women reported improved sexual satisfaction post-circumcision, often attributing it to better hygiene and reduced odor. Individual experiences vary, and psychological or cultural factors may influence perceptions.

Fact # 1: Circumcision can reduce the risk of sexually transmitted infections.

This is a fact. Circumcision offers protective benefits against sexually transmitted infections (STIs) such as HIV, Human Papillomavirus, Herpes Simplex Virus, and bacterial STIs.

• HIV: Randomized controlled trials in Africa showed circumcision reduces HIV acquisition risk in heterosexual men by 50–60%. The foreskin’s inner lining contains many cells that HIV can easily infect, making it more vulnerable to the virus; therefore, circumcision is protective against HIV acquisition.
• Human Papillomavirus (HPV): Circumcision lowers human papillomavirus (HPV) prevalence by 30–40%, reducing transmission and related cervical cancer risk in partners. Studies indicate a 35% lower HPV infection rate in circumcised men.
• Herpes Simplex Virus (HSV): Circumcision is associated with a 25–30% reduced risk of HSV-2 infection. Circumcised men clear HPV infections faster, with studies showing a 50% higher clearance rate of high-risk strains compared to uncircumcised men due to decreased viral load under the foreskin and less favorable conditions for HPV survival on the exposed glans.
• Bacterial STIs: Circumcision may decrease the risk of bacterial infections like chancroid and syphilis, but data is less conclusive, with some studies showing modest reductions (10–20%).

Fact # 2: Circumcision is protective against penile cancer

Circumcision lowers the risk of penile cancer, particularly squamous cell carcinoma, which accounts for most cases. Studies estimate a 3–5-fold reduced incidence in circumcised men compared to uncircumcised men. The protective benefits of circumcision are primarily due to its effects on hygiene and HPV infection rates.

• Hygiene: The foreskin can trap smegma and bacteria, potentially leading to chronic inflammation or balanitis, both risk factors for penile cancer. Circumcision improves genital hygiene, reducing these risks.
• HPV Reduction: Circumcision decreases human papillomavirus (HPV) prevalence by 30–40%. High-risk HPV strains are linked to 50% of penile cancer cases.

Fact # 3: Sutureless techniques can be used for circumcision

A common misconception holds that all circumcision procedures necessitate sutures for wound closure. However, advancements in medical technology have introduced sutureless circumcision techniques. Unlike traditional and laser circumcision methods, which rely on stitches to approximate skin edges for healing, innovative devices such as the Shang Ring and ZSR stapler enable foreskin removal without sutures. These minimally invasive approaches offer substantial advantages, enhancing patient outcomes and procedural efficiency.

Sutureless circumcision significantly reduces operating time to 5–15 minutes, compared to 30–60 minutes for conventional methods. Patients also experience less discomfort, with pain scores averaging 2–3 on a 10-point scale, as opposed to 4–5 for sutured techniques. Conducted under local anaesthesia, these procedures maintain a low complication rate of approximately 2%, ensuring a safety profile comparable to traditional methods. The absence of sutures facilitates faster recovery, allowing patients to resume normal activities sooner.

Fact #4: Circumcision has a low complication rate

Circumcision is generally a safe procedure with consistently low complication rates. Studies show that circumcision has a complication rate of approximately 1–2%. Common complications, such as minor bleeding or infection, are typically mild and easily managed with proper care. Severe complications, like excessive scarring or injury to the penis, are exceedingly rare, occurring in less than 0.1% of cases. Techniques like sutureless circumcision (using devices such as the Shang Ring or ZSR stapler) further enhance safety by reducing procedure time and minimizing tissue trauma, maintaining complication rates comparable to traditional methods.

Performed under local or general anesthesia, depending on the patient’s age and preference, circumcision is designed to prioritize safety and comfort. Post-procedure care, including hygiene and follow-up visits, further reduces risks.

Factor #5: Circumcision can improve premature ejaculation and erectile dysfunction

Circumcision has been shown to offer sexual health benefits, particularly in addressing premature ejaculation (PE) and, to a lesser extent, erectile dysfunction (ED). Research suggests that by removing the foreskin, circumcision exposes the glans, leading to a gradual reduction in penile sensitivity. This desensitization can enhance ejaculatory control, helping men extend their sexual performance. Studies have reported that circumcised men experience improved sexual stamina, with some clinical trials indicating a 20–30% reduction in PE symptoms compared to uncircumcised men. While individual outcomes vary due to psychological and physiological factors, the potential for circumcision to alleviate PE makes it a compelling option for men seeking long-term solutions.

Beyond PE, emerging evidence suggests circumcision may positively influence erectile function. The removal of the foreskin can improve penile hygiene and reduce chronic irritation or inflammation, conditions sometimes linked to ED. A 2013 study observed that men circumcised for medical reasons, such as phimosis, reported enhanced erectile confidence and performance post-procedure, likely due to improved genital health and reduced anxiety about sexual function. Additionally, the psychological boost from addressing foreskin-related discomfort may contribute to better sexual outcomes. While circumcision is not a direct treatment for ED, its indirect benefits—through improved hygiene, reduced sensitivity, and increased confidence—can support erectile performance.

Myth Busted and Benefits Revealed

Circumcision, the surgical removal of the foreskin, is a widely practiced procedure often misunderstood due to myths. Globally, 30–40% of males are circumcised, with varying rates across regions. This article debunks misconceptions, clarifying that circumcision isn’t solely for children or religious purposes, doesn’t eliminate STI risks, and doesn’t always require general anesthesia. Facts highlight its low 1–2% complication rate, protection against penile cancer and STIs like HIV (50–60% reduced risk), and potential to improve premature ejaculation and erectile dysfunction by reducing penile sensitivity and enhancing hygiene. Modern sutureless techniques further improve outcomes, making circumcision a safe, multifaceted option.
