In the United States, circumcision in infant boys is performed for social, medical, or cultural/religious reasons. Once a routine operation urged by pediatricians and obstetricians for newborns in the middle of the twentieth century, circumcision has...

become an elective option that parents make for their sons on an individual basis. Families who practice Judaism or Islam may select to have their sons circumcised as a religious practice. Others choose circumcision for medical benefits.

Female circumcision (also known as female genital mutilation) is usually performed for cultural and social reasons by family members and others who are not members of the medical profession, with no anesthesia. Not only is the prepuce of the clitoris removed but often the vaginal opening is sewn to make it smaller. This practice is supposed to ensure the virginity of a bride on her wedding day. It also prevents the woman from achieving sexual pleasure during coitus. This practice is not universally approved by the medical profession and is considered by many to be a human rights violation.

Some of the medical reasons parents of male infants choose circumcision are to protect against infections of the urinary tract and the foreskin, prevent cancer, lower the risk of getting sexually transmitted diseases, and prevent phimosis (a tightening of the foreskin that may close the opening of the penis). Though studies indicate that uncircumcised boys under the age of five are 20 times more likely than circumcised boys to have urinary tract infections (UTIs), the rate of incidence of UTIs is quite low and treatable with antibiotics. There are also indications that circumcised men are less likely to suffer from penile cancer, inflammation of the penis, or have many sexually transmitted diseases. Here again, there is a low rate of incidence. Good hygiene usually prevents most infections of the penis. Phimosis and penile cancer are very rare, even in men who have not been circumcised. Education and safe sex practices can prevent sexually transmitted diseases in ways that a surgical procedure cannot because these are diseases acquired through risky behaviors.

In 2002, however, new research indicated that circumcised men may be less at risk for contracting HIV infections than uncircumcised men, whose foreskins have higher concentrations of cells that are targeted specifically by HIV. Genital hygiene and safe sex practices are still crucial to preventing the spread of HIV.

Another study during that same year found that circumcised men who engaged in risky sexual behaviors were less likely to contract penile human papillomavirus (HPV), which has been implicated in the incidence of cervical cancer in women. There was little difference between circumcised and noncircumcised men's incidence of the virus if the men were in a monogomous relationship.

With these factors in mind, the American Academy of Pediatrics has issued a policy statement that maintains that though there is existing scientific evidence that indicates the medical benefits of circumcision, the benefits are not strong enough to recommended circumcision as a routine practice.
