Weill Cornell Medical Center -- With the recent endorsement by the World Health Organization (WHO) and scientists worldwide of adult male circumcision as an important strategy for HIV prevention, there is increased urgency to develop safe and cost-effective circumcision services. This is especially the case in Africa where HIV/AIDS continues to spread at an epidemic rate. Studying this method are Dr. Marc Goldstein and physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, who are evaluating an innovative circumcision device developed in China and will initiate a study of the device in Africa in the coming months.
