Circumcision not only protects against HIV in heterosexual men, but it also helps prevent two other sexually transmitted infections, a large new study found. Circumcised males reduced their risk of infection with HPV, or human papillomavirus, by 35 percent and herpes by 28 percent. However, researchers found circumcision had no effect on the transmission of syphilis.
Landmark studies from three African countries including Uganda previously found circumcision lowered men’s chance of catching the AIDS virus by up to 60 percent. The new study stems from the Uganda research and looked at protection against three other STDs. The findings are reported in Thursday’s New England Journal of Medicine
“Evidence now strongly suggests that circumcision offers an important prevention opportunity and should be widely available,” Drs. Matthew Golden and Judith Wasserheit of the University of Washington wrote in an accompanying editorial.
HPV can cause cervical cancer and genital warts. Herpes greatly increases the chances of infection with HIV.
The American Academy of Pediatrics previously said there was not enough evidence to recommend routine circumcision of infants. The doctor’s group is reviewing its position based on recent studies. About 2,800 herpes cases in newborns occur in the U.S. every year transmitted from mothers to infants that can lead to disability or death.
The latest research involved 3,393 HIV-negative heterosexual adolescent boys and men from Uganda who were part of the original HIV study. About half were randomly selected to undergo circumcision right away while the rest had the procedure 2 years later. All had physical exams and were offered voluntary HIV counseling and condoms.
