In what way, other than out of medical necessity, is male circumcision ever ok?

Many ways: There are a number of things that can happen in an uncircumcised male. Urinary tract infections and renal scarring are possible, while in circumcised men the risk is nearly zero. The foreskin can close over the tip of the penis, or around the shaft, and be very painful. We lost almost 300-500k of men from wwii due to emergent circumcision due to those. Plus, we use anesthesia now, minimizing pain.

Circumcision: This is a personal choice. I let the parents of the child decide whether or not to do it. I don't feel it isn't place to deter someone from doing the procedure if that is what they want (religious reasons or any other).

Data: Analysis of all the available research data by the american academy of pediatrics demostrated a benefit of doing it versus the detriment of the risk. The benefit was described as "small", but this does mean there is an advantage to performing it than the risk of not.

Religious reasons: Circumcision is part of being a muslim, jew, or some other religion. Circumcision is also a right of passage from chid to manhood with many african tribes. It is also ok if father or brothers are circumcised and johnny doesn't or might not want to look different to them.

Because it is: The foreskin, like the appendix, offers no benefit to modern man.It may have helped shield the penis when he was running naked through the wilderness, but not today.The pro-con battle has raged for more than 4 decades and research does show health benefits. Why Muslims and Jews knew this so long ago is hard to say. It is still an option you can choose to accept or reject.
