A study in New Zealand has shown that circumcision does not protect men from the common sexually transmitted diseases (STDs) found in the developed world. The study included 499 32-year-old men of which 40% were circumcised.
Recent evidence that circumcision protected men from contracting HIV when having sex with a woman was classified as "compelling" by the study authors, but it was never clear whether or not circumcision protected men from other STDs.
Of the circumcised men in the latest study, 23.4% of them reported having had an STD. A separate study in NZ showed that circumcised men had less STDs by 25 than their fore-skinned counterparts. There were less men involved in that study.
