In studies published in the past decade, the removal of the foreskin provided a 50% reduction in HIV transmission, a threefold reduction in human papillomavirus (HPV) infections in female partners of circumcised men (HPV can cause cervical cancer), and lower rates of syphilis and chlamydia, which causes sterility and is the main sexually transmitted disease among teenagers. Circumcised infants were also roughly 10 times less likely to suffer urinary tract infections and the high fevers associated with them. And circumcision virtually eliminates serious penile cancers, which invade about 1 in 100,000 uncircumcised men.
That's why I circumcised my son.
