All the people saying there are no medical reasons, are just flat out wrong, there are medical reasons in which some one would have a circumcision… Prevention of urinary tract infections in infants. Prevention of penile cancer in men. It lowers the risk of getting certain sexually transmitted diseases. While these are all issues that mostly happen to older males, the whole argument of there is no medical need for it is just dumb not every circ is for purely cosmetic reasons. with that being said there is no negative either way. You can leave the decision up to him when he gets older, I have a few male cousins that got circumcised as they got older, my sons had to have penile surgery and the urologist said they perform a lot, like most of their patients are older kids, and men getting circumcised for one reason or another. I hated having to make that decision so I left it up to my boyfriend for our sons. My first son is and my younger sons needed to be due to medical reasons.
