Yes in accordance to the Quran and Prophetic traditions whilst tattooing and certain other cosmetic surgeries and procedures are forbidden, circumcision is commanded upon Muslim males. And as Muslims, all we can actually say to this is God alone, in His infinite knowledge and wisdom, knows why He commanded us with such and such and forbid us from such and such. It's upon us to follow orders, which AlHamdulillah does have its worldly benefits as well.
