Research conducted in part by Dr. Allan Ronald and the University of Manitoba, long ago showed reduced risk of AIDS transmission in circumcised men. Despite subsequent recommendations by the World Health Organisation, countries have been slow to take up circumcision programming. One of the arguments was that men might be less responsible in their sexual decisions. New research shows that is not the case. Let’s hope the natural protection circumcision offers, combined with good practices, makes a dent in AIDS transmission.
