Infections of the kidney, bladder and urethra happen in uncircumcised baby boys at ten times the rate of circumcised boys, and over a lifetime uncircumcised men are four times more likely to experience one, according to a new analysis of past research. Urinary tract infections (UTIs) are most common in boys' first year of life, and circumcision was already known to make a difference in their risk, but how much and whether that carried through to adulthood was unclear, Australian researchers say. They found that circumcision "provides considerable protection and over the lifespan makes about a three- to four-fold difference by our prediction, which is quite striking in public health terms," lead study author Brian Morris, professor of molecular medical science at the Sydney Medical School, University of Sydney, told Reuters Health. Morris and a colleague examined 22 studies published between 1987 and 2012 that included a total of 407,902 males across the globe, a quarter of whom were uncircumcised. Breaking down the results by age, they calculated that the likelihood of a UTI between birth and one year of age is 9.9 times higher in uncircumcised boys compared to circumcised boys. Between ages 1 and 16, uncircumcised boys are at 6.6 times higher risk, and after age 16 their risk is 3.4 times that of uncircumcised men. Based on those findings, the researchers projected that doctors could prevent one UTI with every four circumcisions, "which is astronomical," Morris said. The younger the infant, the more serious a UTI can be, the researchers note in their report, which is published in the Journal of Urology. Side effects of a UTI in infants can include kidney scarring, fever, pain and blood infections. Health experts have mostly framed circumcision as a public health preventive measure focused on HIV and other sexually transmitted diseases.
