There are reasons to get it done. I was amazed at some of them. Here is an example
There is a higher risk of gonorrhea and inflammation of the urethra (the tube that carries the urine from the bladder outside) in uncircumcised men. It has also been reported that other sexually transmitted diseases (such as chancroid, syphilis, human papillomavirus, and herpes simplex virus type 2 infection) are more frequent in uncircumcised men.
Then there were the other problems like Phimosis,Paraphimosis,Balanitis and posthitis,balanoposthitis etc. I never knew about any of these. If you care to read more the link I learned about this stuff is http://www.medicinenet.com/circumcision_the_medical_pros_and_cons/article.htm
Personally I believe it is a matter of choice but from the feedback I got from my sons they were happy to have it done.
The standard of care used for all other pediatric surgery requires the medical benefits of the surgery to significantly outweigh the medical risks and harms or for the surgery to correct a congenital abnormality. Elective non-therapeutic circumcision of boys is the only surgery that violated that standard of care.
Using the same logic used in the article you cited, there are reasons to circumcise girls. If a girl's labia minora is cut off when she is a child, she will never get cancer of the labia and she will never get infections of the labia. However these small potential medical benefits do not significantly outweigh the medical risks and harms of the surgery.
If someone used that line of reasoning to justify female genital cutting of girls, no one would fall for it. Why do we as a society give it credibility when it is used to justify male genital cutting of boys?
It is past time for American doctors to start using the same standard of care for a boy's foreskin that they now use for a girl's labia and for all other parts of a child's body, i.e. surgery is only performed when the medical benefits of the surgery significantly outweigh the medical risks and harms or the surgery corrects a congenital abnormality.
I also believe it is a matter of choice. I believe it should be the choice of the male himself once he is old enough to give his own informed consent about whether or not he wants to have a normal, healthy, functional part of his penis cut off for social or cultural reasons.
How much do you sons know about circumcision and the normal male anatomy? For example do they know the following facts?
