RT Journal Article SR Electronic T1 Programme science research on medical male circumcision scale-up in sub-Saharan Africa JF Sexually Transmitted Infections JO Sex Transm Infect FD BMJ Publishing Group Ltd SP 345 OP 349 DO 10.1136/sextrans-2012-050595 VO 89 IS 5 A1 Ronald H Gray A1 Maria J Wawer A1 Godfrey Kigozi YR 2013 UL http://sti.bmj.com/content/89/5/345.abstract AB Three randomised trials demonstrate that voluntary medical male circumcision (MMC) reduces male HIV acquisition by 50–60%, and post-trial surveillance has shown that the effects are long lasting. Scale-up of services has been initiated in 14 high-priority sub-Saharan African countries with high rates of HIV and low prevalence of MMC. However, circumcision coverage in the region remains low. Challenges to MMC rollout include suboptimal demand among higher-risk men, the need to expand access and reduce costs of MMC through personnel task shifting and task sharing, assuring and maintaining a high quality of service provision, and the testing and introduction of non-surgical devices. In addition, early infant male circumcision has not been adequately evaluated in Africa. Here, we describe challenges to implementation and discuss the ongoing and future role of implementation and programme science in addressing such challenges.
