In recent years, several large-scale randomized controlled clinical trials have demonstrated that adult male circumcision is effective in reducing the sexual transmission of human immunodeficiency virus (HIV), human papillomavirus (HPV), and herpes simplex virus type 2 (HSV-2). In 2005-2007, French and American scientists demonstrated through large-scale randomized controlled studies that male circumcision can reduce the rate of transmission of HIV from women to men by 50% to 60%. To promote male circumcision, UNAIDS and WHO published 11 conclusions and 43 recommendations on male circumcision for HIV prevention, followed by a series of policy and technical guidelines on the promotion of male circumcision.
