Other infections

Studies evaluating the effect of circumcision on the rates of other sexually transmitted infections have, generally, found it to be protective. A 2006 meta-analysis found that circumcision was associated with lower rates of syphilis, chancroid, and possibly genital herpes. A 2010 review found that circumcision reduced the incidence of HSV -2 (herpes simplex virus, type 2) infections by 28%. The researchers found mixed results for protection against trichomonas vaginalis and chlamydia trachomatis, and no evidence of protection against gonorrhea or syphilis. It may also possibly protect against syphilis in MSM.
