Why have male Circumcision rates in the US dropped by 10% in the last 32 years? There are three main reasons that from 1979 to 2010 circumcision rates have fallen from 65 percent to 55 percent in the US.

The circumcision data only reflects males circumcised in hospitals and does not account for circumcisions performed outside of hospitals or those done following a newborn's discharge from its birth hospital, but the data definitely reflects a change in attitudes towards the procedure and and societal changes.

The reasons for the drop in circumcision rates are health plans not covering the procedure, parents being more aware of  the surgery and not just taking doctors words at face value, and the acceptance of uncircumcised penises in American society.

Medicaid has stopped funding the procedure in 18 states, many of which are in the West, including Arizona, California, Oregon and Washington. So much more less parents are willing to spend thousands of dollars on a procedure that is not totally needed.

Also, approval of uncircumcised penises amongst children has added to the decline.

Thomas McInerny, president of the American Academy of Pediatrics, told Bloomberg News, I've been in practice for over 40 years and there wasn't any question about whether to circumcise in the 'good old days' because parents were worried about what might happen in the locker room in middle school or high school.

 "But circumcision is less frequent in Europe and Asia, so in time as more immigration has occurred, there are more uncircumcised floating around in locker rooms, so you're not going to get an embarrassing situation."

Parents are more informed of the negative impacts of the procedure, instead of it just being considered the norm.

"Parents are more thoughtful about circumcision now than they were a decade or two ago when circumcision was a given," McInerny said.

"It's a brutal and unnecessary procedure to inflict on a baby that can't consent," Georganne Chapin, the executive director of the anti-circumcision advocacy group Intact America, told Bloomberg News.

"The biggest reason people have moved from circumcising their children, moving toward leaving their children as they're born, is they've realized circumcision isn't necessary and it's painful."
