The World Health Organization (WHO) and its partners are calling for case examples of efforts to enhance uptake of voluntary medical male circumcision (VMMC) among adult men, with a deadline of 30 March 2019. A selection of the cases will be included in the new WHO guidance on VMMC to be issued later in 2019. This call is for practices that led to increased uptake and those that did not affect uptake, as part of the learning process and to guide decisions about future effective implementation. The document also provides a template for submitting case examples.
