Circumcision and HIV

A new study, done in Africa, where HIV/AIDS is predominantly spread through heterosexual sex, suggests that circumcision can cut a male’s risk of acquiring HIV/AIDS. The findings were that removing the foreskin removes a host for the HIV to enter the body. In addition, the removal of these cells may provide an indirect boost to the immune system. Note, however, that while the study is getting a lot of publicity, and even optimism about the further benefits of circumcision, it is only preliminary, and does not yet belong in the category of conclusive findings.
