The human papillomavirus (HPV) is the most common STD in the U.S. It is known to cause genital warts, and it has been implicated as the cause of [[cervical cancer ]] in womenand [[penile cancer]] in men.

Two vaccines have recently been developed to prevent HPV acquisition. In the past, [[circumcision ]] was assumed to prevent the acquisition of HPV, thus reducing the risk of cervical cancer, but this was supported by dubious studies as outlined below.

}}</ref> This study tested for HPV at three sites: the [[scrotal skin|scrotum]]/[[shaft skin]], the glans, and in [[urine ]] samples. The authors of this study found that in circumcised men, the [[scrotal skin|scrotum]]/[[shaft skin ]] contained was most often the site of HPV infection. The authors also note that many large-scale studies fail to test for HPV on [[scrotal skin|scrotum]]/[[shaft skin]].
