I recognise aspects of religious practices was a way to keep followers healthy in the absence of what we would call modern medicine and some of the practices are environmentally driven to some degree. Circumcision is one, dusty desert like locations had limited water, making it harder to wash regularly but in hot desert like area's one's libido will increase, so its the result of trying to reduce the spread of disease. The irony is that the Langerhan cells are removed which plays a part in the immune system response, but it might be considered an attack vector for at least the HIV virus to enter the body according to other reports. What these reports show is even the medical profession are split on whose theory is correct. I've always been informed the main reason in the past has been because blokes are lazy and didnt wash enough and some religions were so anti-sex it was a way of reducing other problems with the foreskin that can arise.
