Britain launched its national health-care program after the Second World War, doctors and politicians scrutinized common medical procedures in order to determine which ones the government should pay for. Circumcision had been in vogue there, as in the United States, for several decades, but in the absence of solid evidence for its health benefits, the postwar English government opted not to pay for it, and only a small percentage of British boys who are not Jewish or Muslim have undergone the procedure since. The American Pediatric Association has waffled on the subject for the past few decades.
Doctors tend to advise it and insurance companies cover it.
It's the crossed-legs read of the year. Both Jews and Muslims do it on scriptural authority. Sixty or so generations of uncut Christians later, in the 19th century, a few influential American and British doctors began touting circumcision as a prophylactic against everything from venereal disease and masturbation to epilepsy and paralysis. Except in the case of disorders resulting from attached or too-tight foreskins, which can't ordinarily be diagnosed until puberty anyway, the medical evidence is fuzzy. Penile cancer virtually never strikes circumcised men, but it's a rare disease in any event, and its incidence among the almost unanimously uncut men of Finland and Denmark is significantly lower than that in the United States.
