Circumcision is the surgical removal of the foreskin, the skin that covers the head of the penis. It may be performed on babies, children, or adults for medical, religious, cultural, family, or personal reasons.
For some families, circumcision is mainly a religious or cultural decision. For others, it is considered because of possible health and hygiene benefits. In adults, circumcision is often performed for medical reasons, such as phimosis, recurrent balanitis, repeated foreskin infections, tearing, discomfort during sex, or difficulty keeping the area clean.
Circumcision can offer benefits for some boys and men, but it is still a surgical procedure and should be considered carefully and seriously. The possible benefits include easier hygiene, a lower risk of some infections, prevention of foreskin problems such as phimosis and paraphimosis, and a reduced risk of certain rare conditions. The possible risks include pain, bleeding, infection, swelling, cosmetic dissatisfaction, adhesions, meatal stenosis and, rarely, glans injury or the need for further surgery.
Circumcision is not medically necessary for every boy or man. The decision depends on the person’s age, symptoms, medical history, personal circumstances, cultural or religious values, and the reason for considering circumcision. Understanding both the benefits and the risks can help parents and adult men make an informed decision.
What are the benefits of circumcision?
The possible benefits of circumcision include easier hygiene, a lower risk of some infections, prevention of certain foreskin problems, and a reduced risk of some rare conditions later in life.
The main potential benefits include:
- Easier to maintain hygiene
- Lower risk of urinary tract infections, especially in infancy
- Lower risk of sexually transmitted infections
- Prevention of phimosis (tight foreskin) or Lichen sclerosus (BXO)
- Prevention of paraphimosis
- Reduced risk of recurrent balanitis or balanoposthitis
- Lower risk of penile cancer
- Possible reduction in transmission of some HPV-related infections to female partners
The importance of each benefit varies from person to person. The benefits may be more relevant for someone with a tight, painful or repeatedly inflamed foreskin than for someone with no symptoms.
1. Easier to maintain hygiene
Circumcision can make it easier to keep the penis clean because there is no foreskin to retract and clean underneath. This may reduce the build-up of moisture, bacteria and smegma around the head of the penis.
However, circumcision is not the only way to maintain good hygiene. Boys and men who are not circumcised can usually keep the area clean with normal washing once the foreskin becomes naturally retractable.
In young boys, the foreskin should not be forced back. It is normal for the foreskin to be non-retractile in early childhood, and it usually separates naturally over time.
2. Lower risk of urinary tract infections
Circumcision is associated with a lower risk of urinary tract infections, especially during infancy.
UTIs in boys are not common, but they can sometimes lead to more serious infections if they spread to the kidneys. For boys at higher risk of urinary problems, this benefit may be more important, especially under 1 year of age.
For most healthy boys, the overall risk of UTI is still low. This benefit should be considered alongside the possible risks of the procedure and the reasons for considering circumcision.
3. Lower risk of some sexually transmitted infections
Circumcision can reduce the risk of some sexually transmitted infections. The strongest evidence is for a reduced risk of HIV transmission from female to male partners in higher-risk heterosexual populations. Circumcision may also reduce the risk of some infections linked to human papillomavirus and herpes.
This benefit should not be misunderstood. Circumcision does not prevent sexually transmitted infections completely. It is not a substitute for condoms, STI testing, HPV vaccination where appropriate, or safer sexual practices.
The protective effect is not the same in every setting or for every type of sexual activity. It is best understood as a possible risk reduction, not complete protection.
4. Prevention of phimosis
Phimosis is when the foreskin is too tight to retract over the head of the penis.
In young boys, a non-retractile foreskin is often normal and does not always need treatment. In older boys and adults, however, phimosis can sometimes cause pain, tearing, infections, difficulty cleaning, ballooning during urination or discomfort during sex.
Circumcision removes the foreskin, so it prevents phimosis from recurring. It may be recommended when phimosis is severe, scarred, recurrent or not improving with other treatment. Circumcision is indicated in lichen sclerosus or BXO, which is a chronic skin condition causing phimosis, especially in diabetes
5. Prevention of paraphimosis
Paraphimosis happens when the foreskin is pulled back behind the head of the penis and becomes stuck. This can cause swelling, pain and restricted blood flow.
Paraphimosis is a medical emergency. Circumcision prevents future paraphimosis because the foreskin is removed.
6. Reduced risk of recurrent balanitis
Balanitis is inflammation of the head of the penis. Balanoposthitis is inflammation of both the glans and foreskin.
Symptoms may include redness, soreness, swelling, itching, discharge, odour or discomfort. Some boys and men experience repeated episodes, especially when the foreskin is tight or difficult to clean.
Circumcision may reduce the risk of recurrent balanitis by removing the foreskin and reducing areas where moisture and irritation can build up.
7. Lower risk of penile cancer
Penile cancer is rare, but it is less common in men who have been circumcised, particularly when circumcision was performed in infancy.
This does not mean circumcision is necessary for every boy or man. Good hygiene, avoiding smoking, HPV prevention, and seeking medical advice for persistent penile changes are also important.
Any persistent lump, ulcer, bleeding, thickened skin, colour change, discharge, or unexplained soreness should be assessed by a doctor.
8. Possible benefits for female partners
Circumcision may reduce transmission of some high-risk types of HPV, which are linked with cervical cancer. Some research has also suggested reduced risks of certain infections in female partners of circumcised men.
This should be seen as a possible health benefit rather than a guaranteed individual outcome. Cervical screening, HPV vaccination and safer sex remain important whether a male partner is circumcised or not.
What are the risks of circumcision?
Circumcision is generally safe when performed by an experienced clinician in a suitable clinical setting with sterile technique and appropriate pain relief. However, complications can still happen.
The possible risks of circumcision include:
- Pain and discomfort
- Bleeding
- Infection
- Swelling and bruising
- Sensitivity of the head of the penis during healing
- Too much or too little foreskin removal
- Adhesions or skin bridges
- Meatal stenosis
- Cosmetic dissatisfaction
- Delayed healing
- Rare injury to the penis or urinary opening
- Need for revision surgery in some cases
Most complications are minor and treatable, but the possibility of complications should be understood before the procedure.
1. Bleeding
A small amount of bleeding after circumcision can be normal. Persistent bleeding, bleeding that soaks dressings, or bleeding that does not stop with gentle pressure should be checked urgently.
The risk of bleeding is higher if the person has a bleeding disorder or is taking medication that affects blood clotting. A medical history should be checked before the procedure.
2. Infection
Infection is uncommon but possible. Warning signs include increasing redness, swelling, worsening pain, pus, foul-smelling discharge or fever.
Good aftercare helps reduce this risk. The area should be kept clean and dry, and aftercare instructions should be followed carefully.
3. Pain and discomfort
Circumcision can cause pain during and after the procedure. Appropriate pain relief should always be used.
For babies and children, this usually involves local anaesthesia and comfort measures. For adults, circumcision may be performed under local anaesthetic, local anaesthetic with sedation, or general anaesthetic depending on the clinical situation.
After the procedure, soreness, swelling and sensitivity are expected while the area heals.
4. Swelling, bruising and sensitivity
Swelling and bruising are common after circumcision, especially in older boys and adults. The head of the penis may also feel very sensitive at first because it is newly exposed.
This usually improves gradually as healing progresses. In adults, swelling and sensitivity may take several weeks to settle fully.
5. Too much or too little skin removal
One possible complication is removing too much or too little foreskin.
If too little skin is removed, there may be a loose fold of remaining foreskin or a need for revision. If too much skin is removed, it may cause tightness, discomfort or cosmetic dissatisfaction.
This is one reason why circumcision should be performed by an experienced clinician.
6. Adhesions or skin bridges
Sometimes the remaining skin can stick to the head of the penis during healing. Minor adhesions may resolve or be treated conservatively, but more significant adhesions or skin bridges may require medical treatment.
Correct aftercare and follow-up can reduce this risk.
7. Meatal stenosis
Meatal stenosis is the narrowing of the urinary opening at the tip of the penis. It is an uncommon complication.
Signs may include a narrow urine stream, spraying, straining, pain when passing urine, or irritation around the tip of the penis. These symptoms should be assessed by a doctor.
8. Unsatisfactory cosmetic result
Some patients or parents may be unhappy with the final appearance after circumcision. This may relate to scarring, uneven skin, excess remaining skin, tightness, or a result that does not match expectations.
A consultation before the procedure can help explain what is realistic and what the area may look like during healing.
9. Rare serious complications
Serious complications are rare but can include significant infection, injury to the glans, urethral injury, severe bleeding or the need for further surgery.
The risk is lower when circumcision is performed in a proper clinical setting by a trained and experienced clinician using sterile technique and appropriate pain control.
Do the benefits of circumcision outweigh the risks?
For some people, the benefits of circumcision may outweigh the risks. This may apply when circumcision is needed for a medical reason such as recurrent balanitis, scarred phimosis, paraphimosis, repeated infections or foreskin-related pain.
For babies and children, the decision is often more personal. Circumcision may offer some health benefits, but it is not medically necessary for every child. Parents may also consider religious, cultural, family and ethical factors.
The balance of benefits and risks is different for each person. It depends on age, symptoms, medical history, risk factors, personal values and the reason circumcision is being considered.
Is circumcision safer in babies or adults?
Circumcision is usually simpler in newborns than in adults. Babies generally heal faster, and the complication rate is usually lower.
Adult circumcision can still be safe and effective, but recovery takes longer. Adults usually need more wound care, more time away from strenuous activity, and a longer period before returning to sexual activity.
For adults, circumcision may be recommended for:
- Phimosis
- Recurrent balanitis or balanoposthitis
- Paraphimosis
- Recurrent foreskin infections
- Foreskin scarring
- BXO or lichen sclerosus
- Pain, tearing or tightness during sex
- Hygiene difficulties caused by a tight foreskin
Recovery after circumcision
Recovery depends on age, technique, general health and individual healing.
In babies, healing is often complete within 7 to 10 days. Mild swelling, redness, sensitivity and a yellowish film during healing can be normal.
In adults, recovery is longer. Many men can return to light work within several days, but swelling, bruising and sensitivity can continue for a few weeks. Full healing commonly takes around 4 to 6 weeks.
Sexual activity and masturbation should usually be avoided for around 6 weeks, or until the wound has fully healed and a clinician confirms it is safe.
When to seek medical advice after circumcision
Medical advice should be sought urgently if there is:
- Bleeding that does not stop
- Fever
- Increasing redness, swelling or pain
- Pus or foul-smelling discharge
- Difficulty passing urine
- No urination within the advised time after the procedure
- Worsening colour change of the penis
- Severe pain not controlled with medication
- Wound opening
- Significant swelling that is getting worse
Does circumcision affect sexual function or sensation?
Many men worry that circumcision may affect sensitivity, erections, orgasm or fertility.
Circumcision does not usually cause problems with fertility, erections or sexual function. Individual experiences can vary. Some men report little or no change, some notice changes in sensitivity, and some feel improvement if circumcision has treated pain, tightness, tearing or recurrent inflammation.
Adult men considering circumcision should discuss this before the procedure, especially if the reason is pain, tightness or sexual discomfort.
Is circumcision a personal choice?
Circumcision is a personal decision unless there is a clear medical reason for it.
Some families choose circumcision for religious, cultural or family reasons. Others prefer not to circumcise unless a medical problem develops. Both decisions should be based on clear information about benefits, risks, aftercare and alternatives.
Medical views can also differ depending on the country, healthcare system and individual circumstances. Some medical organisations recognise that circumcision has potential health benefits, while others emphasise that the benefits may not be strong enough to recommend routine circumcision for every child.
For adults, the decision is made by the patient after considering symptoms, recovery, risks, personal preference and possible alternatives.
Are there alternatives to circumcision?
There may be alternatives to circumcision depending on the problem.
For mild foreskin tightness, treatment may include time, gentle stretching advice or steroid cream under medical supervision. For inflammation or infection, treatment may involve hygiene advice and antifungal or antibiotic therapy, depending on the cause.
However, alternatives may not be suitable for everyone. Circumcision may be recommended if the foreskin is scarred, repeatedly infected, causing significant symptoms, or if previous treatments have not worked.
Is circumcision medically necessary?
Circumcision is not medically necessary for every boy or man.
For babies and children, the decision may involve religious, cultural, family and health considerations. For adults, circumcision is more commonly considered when there is a medical problem affecting the foreskin.
In the UK, circumcision may be performed for medical, religious, cultural or personal reasons depending on the setting and the patient’s circumstances.

Who should not have a circumcision immediately?
Circumcision may need to be delayed or avoided if there are certain medical concerns, including:
- Premature birth or unstable health in a newborn
- A bleeding disorder or family history of abnormal bleeding
- Certain penile abnormalities, such as hypospadias
- Active infection
- Medical conditions that make surgery or anaesthesia unsafe
A clinical assessment is important before circumcision.
Making an informed decision
Before circumcision, it is important to consider:
- The reason for circumcision
- The person’s age
- Any symptoms or medical conditions
- Possible alternatives
- The expected recovery
- Pain control
- Aftercare requirements
- The experience of the clinician
- Personal, cultural or religious values
Circumcision can be beneficial for some boys and men, especially when there is a medical reason affecting the foreskin. For others, the benefits may be less significant. The decision should be based on balanced information, realistic expectations and individual circumstances.
