Tiki, except that study was shown to be false. The fact that HIV infections are much higher in the US where circumcision is the norm as compared to countries like the UK where circumcision is not the norm. Penile cancer in uncircmcised men is less likely than Breast Cancer in men. For these reason all medical associations have found there are no significant health benefits for circumcision.
Please don't take this as a personal attack. I just feel you have gotten hold of some info that has been discredited in recent years.
