What is the function of circumcision?

The medical benefits of male circumcision outweigh its risks for heterosexual males. These include:

- Reduced risk of sexually transmitted infections (STIs): Male circumcision has been shown to reduce the risk of acquiring several sexually transmitted infections, including HIV, herpes simplex virus (HSV), human papillomavirus (HPV), and syphilis. Circumcised men are also less likely to develop urethral stricture, a narrowing of the urethra that can cause difficulty urinating.

- Reduced risk of penile cancer: Male circumcision has been shown to reduce the risk of penile cancer by about 50%. Penile cancer is a rare cancer, but it is often deadly if not caught early.

- Improved hygiene: Male circumcision can make it easier to clean the penis, which can help to prevent infection.

- Potential benefits for female sexual partners: Male circumcision has been shown to reduce the risk of certain STIs in female sexual partners, including trichomoniasis, bacterial vaginosis, and cervical cancer.

There is no evidence that male circumcision has any negative health effects. In fact, some studies have shown that circumcision may actually have some health benefits, such as reducing the risk of urinary tract infections (UTIs) and balanitis (inflammation of the glans penis).

For all of these reasons, the American Academy of Pediatrics (AAP) recommends that all male infants be circumcised.
