Men who are circumcised have a lower chance of becoming infected with HPV.  Men who have not been circumcised are more likely to be infected with HPV  and pass it on to their partners. The reasons are unclear, researchers theory is that the surface of the foreskin (which is removed by circumcision) is easily infected by HPV. Although, Circumcision does not completely protect against HPV infections, men who are circumcised can still be infected and pass it to their partners.
