The recent decline in the percentage of U.S. boys who are circumcised may lead to an increase in future healthcare costs and sexually transmitted infections, according to a new study.

The decrease in the circumcision rate occurred over the same time period in which researchers found increasing evidence of the procedure's health benefits, the researchers said.
Studies conducted in Africa have shown that circumcision reduces the risk of acquiring HIV by about 60 percent, and the risk of acquiring human papillomavirus (HPV), by about 50 percent, said Dr. Stephen Moses, a medical microbiology professor at the University of Manitoba in Canada, who was not involved in the new study. Women whose male partners have been circumcised also have a lower risk of some vaginal infections, Moses said.
"If you put all that together, it's a pretty substantial healthbenefit overall," Moses said.
Studies conducted in the United States, although less rigorous in their design, have found similar benefits.
But so far, 18 states have abolished Medicaid coverage for male infant circumcision, the researchers said.
In the new study, Dr. Aaron Tobian of Johns Hopkins University and colleagues created a computer program that assumed 10 percent of males born in a given year were circumcised. The researchers said they chose 10 percent because that is the percentage of boys circumcised in Europe, where insurance coverage for circumcision is limited.
Under this scenario, HIV infections would increase by an estimated 12.2 percent, compared with the current number of cases among sexually active men. HPV infections would increase by an estimated 29.1 percent, and genital herpes infections would increase by 19.8 percent. Additionally, 26,800 more boys would develop urinary tract infections during infancy than currently do, the researchers found.
Among women, cases of bacterial vaginosis would be expected to increase by 51.2 percent, and cases of infection with high-risk HPV types would increase by 18.3 percent.
These results are based on the current prevalence of sexually transmitted infections in the United States. If there was a new treatment available, such as a vaccine for HIV, then the benefit of circumcision would have to be recalculated, Moses said.
