Male circumcision is the surgical removal of the foreskin. The foreskin is the fold of skin covering the end of the penis, which can be gently pulled back.
Circumcision may be performed for:
This article focuses on the medical aspects of circumcision.
During the 19th century, many medical practitioners believed that being circumcised was more hygienic than not being circumcised.
As a result, the routine medical circumcision of all boys, regardless of religious faith, became a widespread practice. However, routine male circumcision gradually became less common as many members of the medical community began to argue that it had no real medical benefit in the vast majority of cases.
Routine circumcision may offer a number of potential benefits, such as reducing the risk of some types of infections. However, most healthcare professionals now agree that the risks associated with routine circumcision, such as infection and excessive bleeding, outweigh any potential benefits.

In rare cases, circumcision may be considered for the following health conditions:
However, these conditions are extremely rare in children and other treatments are often preferred.
Circumcision may also be considered in some cases for adults with the following health conditions:
Read more about why circumcision may be necessary.
Circumcision for medical reasons is usually carried out on a day-patient basis. This means that you or your child will not have to stay overnight in hospital.
If a baby boy needs to be circumcised, he will usually be given a local anaesthetic because it is safer than a general anaesthetic. Local anaesthetic is a numbing medicine, which can be injected into the base of the penis or applied as a cream.
Older children and adults who are circumcised are usually given a general anaesthetic, where they are put to sleep.
The circumcision procedure is relatively simple. The foreskin is removed with a scalpel, scissors or a surgical clamp. Any bleeding is cauterised (closed using heat), and the remaining edges of skin are stitched together using dissolvable stitches.
After circumcision, there may be some pain and swelling, and the penis will be easily irritated until it heals. The healing process can take up to 7 to 10 days in babies, and up to 4 to 6 weeks in older boys and men. Read more about recovering from circumcision.
If there are signs of any bleeding or infection after a circumcision, speak to your doctor. Complications are rare when circumcision is performed for medical reasons, but there are some risks of circumcision which should be considered.
As with all types of surgery, circumcision has some risks. However, complications from circumcisions carried out for medical reasons are rare.
Bleeding and infection are the most common problems associated with circumcision.
Other complications can include:
Problems with circumcisions carried out for religious or cultural reasons may go unreported.
This section describes only the medical reasons why circumcision may be necessary. It is outside the scope of this article to discuss religious or cultural reasons for circumcision.
Paraphimosis is a medical emergency. The foreskin is pulled back underneath the tip of the penis, becomes trapped and cannot be returned to its original position.
Paraphimosis sometimes happens as a complication of a medical procedure that involves pushing back the foreskin for a prolonged period of time. Such procedures include:
Paraphimosis causes a band of swelling to develop around the penis, which can block the blood supply. If paraphimosis is not treated, the lack of blood supply will mean that the tissue of the penis will begin to die.
In most cases, paraphimosis can be treated using medication to reduce the swelling, or minimally invasive surgery to return the foreskin to its original position.
Paraphimosis is extremely rare in children and other treatments are preferred. Circumcision is usually only required in adults in rare cases when medication and surgery fail. Occasionally, circumcision may be recommended if someone has repeated episodes of paraphimosis.
Balanoposthitis is inflammation of the foreskin, usually caused by a bacterial infection.
Symptoms of balanoposthitis include:
Balanoposthitis can be successfully treated using antibiotics. Most people do not have further infections. Circumcision is usually recommended only in adults in rare cases where someone has repeated infections (recurrent balanoposthitis).
A urinary tract infection (UTI) is an infection of the urinary system.
About 4% of boys have at least one UTI before they are 16.
Research has found that circumcised boys are 10 to 14 times less likely to catch a UTI than uncircumcised boys. This is because many UTIs are thought to be caused by bacteria that gather inside the foreskin before spreading to the urinary system.
However, most UTIs are mild and do not cause serious damage. Circumcision is usually only recommended if a boy has a risk factor that increases the likelihood of repeated UTIs. Repeated UTIs can cause kidney damage.
An example of a pre-existing risk factor is a birth defect that causes urine to leak back up into the kidney. This carries the risk of bacteria spreading from the foreskin, through the urine, and infecting the kidney. In such circumstances, circumcision may be recommended.
Circumcision is known to reduce the risk of catching three sexually transmitted infections (STIs). These are:
Research in Africa found that heterosexual circumcised men are 38-66% less likely to contract HIV than uncircumcised men.
It is thought that the foreskin contains special cells that attract the cells of the HIV virus. This means that uncircumcised men who have vaginal sex with an HIV positive woman are more likely to develop the infection.
However, it is still unclear whether circumcision has the same protective effect for homosexual men who have unprotected anal sex. There also seems to be no protective benefits for female sexual partners of heterosexual circumcised men.
Circumcision is known to reduce the risk of a man getting syphilis and chancroid. This is thought to be because:
It is estimated that uncircumcised men are:
However, circumcision is nowhere near as effective as condoms in preventing STIs. If used correctly, condoms are 98% effective in preventing STIs.
Research has shown that men who are circumcised in childhood are three to four times less likely to develop penile cancer than men who are uncircumcised. This is because many cases of penile cancer develop in the foreskin.
However, cancer of the penis is very rare. On average, 400 new cases are diagnosed each year in the UK. It would, therefore, be very difficult to justify routine circumcision as a method for preventing penile cancer.
However, in some rare cases a person may be more at risk, for example if they have a family history of penile cancer or a weakened immune system. In such cases, circumcision is recommended as a preventative measure.
Balanitis xerotica obliterans (BXO) is a skin condition that can only be cured with circumcision. Howeer, the condition is rare in children and usually affects adults.
BXO can cause hardening and inflammation of the penis, usually affecting the foreskin and tip of the penis. It causes symptoms such as:
In cases of BXO that primarily affect the foreskin, circumcision is usually the most effective treatment, and often results in a complete cure.
In babies who are circumcised, the foreskin usually takes about 7 to 10 days to heal. In older boys and men, the healing process can take up to four to six weeks.
As circumcision is a painful procedure, painkillers such as paracetamol or ibuprofen will need to be taken for at least the first three days after the operation. Children who are 16 years old or younger should not take aspirin.
Circumcision exposes the sensitive skin of the tip of the penis (glans). In babies, nappies can rub against the glans, making it sore. Therefore, make sure that you tuck down your baby’s penis before putting the nappy in place.
After circumcision, the penis will be red and swollen for a few days. You or your child may find it more comfortable to wear loose clothing for a while. Putting petroleum ointment directly on to the area can also reduce irritation.
After a boy has been circumcised, make sure that he does not ride a bike or use other sit-on toys until the swelling has completely gone down. If he is of school age, he should be able to return to school about a week after being circumcised. However, let his teacher know that he has had the operation.
The tip of the penis should not get wet for 48 hours after a circumcision, after which it is important to keep it clean with showers or baths once or twice a day. Do not use scented products and leave the penis to dry naturally.
For adults, the surgeon will give advice about sexual activity. Usually, sex should be avoided until the wound has healed, to avoid it reopening.
After a child has been circumcised, speak to your doctor if:
Older boys and men should also see their doctor if they have any problems after circumcision.
There are several potential advantages and disadvantages associated with circumcising boys shortly after they are born.
Read about why circumcision is necessary for more details about the potential advantages of circumcision.
Most healthcare professionals maintain that the potential benefits of circumcision are not strong enough to justify routine childhood circumcision. Critics of circumcision argue that it has disadvantages, such as:
Critics have also argued that routinely circumcising baby boys on medical grounds violates the principle of consent to treatment. They say that circumcision should only be performed when a boy is old enough to make an informed decision about whether he wishes to be circumcised.
