New Scientific Data on Male Circumcision
Circumcision Protects Against Several Sexually Transmitted Infections
By C. Vidya Shankar, MD
MEXICO CITY (Reuters Health) Aug 07 - Male circumcision has a protective effect against HIV, human papilloma virus and trichomonas vaginalis infections, researchers reported at the International AIDS Conference here.
Dr. Robert C. Bailey from the University of Illinois at Chicago and his team from Kenya reported 42-month follow-up results on the protective effects of male circumcision. They had previously reported encouraging results after 24 months of their randomized trial, which was stopped in December 2006 due to significant protective benefits, with the controls also being offered circumcision.
The cumulative incidence of HIV infection over 42 months among circumcised men was 2.6% as compared to 7.4% among controls, the researchers observed. The protective effect of circumcision was 64% (i.e., relative risk of infection, 0.36), they noted.
Male circumcision provides a sustained protective effect against HIV, Dr. Bailey's team concludes.
In another study, Dr. Bertran Auvert from Universite de Versailles, France and his team from South Africa analyzed the protective effect of male circumcision against other sexually transmitted infections.
In their randomized study of men aged between 18 and 24, the prevalence of human papilloma virus and trichomonas vaginalis was lower in the circumcised group with odds of 0.57 and 0.54, respectively, after 21 months follow up, they report. There was no effect on gonorrhea rates.
"Circumcision could therefore be an indirect way of limiting the risk of genital cancers caused by HPV in women," Dr. Auvert said during a related press conference.
Male circumcision can prevent between 2 to 8 million new HIV infections in the sub-Saharan Africa, resulting in savings of around $2 billion over the next 20 years, Dr. Auvert said.
Male circumcision is safe, with minimal side effects, and can be promoted as a universal preventive measure against HIV, Dr. Dirk Taljaard, one of the co-authors of the second study told Reuters Health.
"The studies of male circumcision have opened up a whole new era in the fight against AIDS: we now potentially have a new method of prevention," Professor Jean-Francois Delfraissy concluded during the press conference.
