I'm an RN and it is actually done at various ages for various reasons. When it's a younger boy, such as the above, typically it's done due to phimosis, a condition in which the foreskin never retracted like it should have as the infant boy gets older. Normally, for older men, it's done for cosmetic reasons. Either way, they are ALL performed under general anethesia. Our OR schedule typically has 1-2 scheduled per week.
Well I understand if there is a health concern what has to be done has to be done. It looked like the article was saying that health professionals were recommending it so but it did not say why.
