 Results from the Decision Makers Program Planning Tool DMPPT models, performed in 2011, suggest that scaling up adult voluntary medical male circumcision VMMC to reach 80 coverage in the 13 countries by 2015 would entail performing 20.34 million circumcisions between 2011 and 2015 and additional 8.42 million between 2016 and 2025. Such a scale-up would result in averting 3.36 million new HIV infections through 2025. In addition, while the model shows that this scale-up would cost a total of US2 billion between 2011 and 2025, it would result in net savings due to averted treatment and care costs amounting to US16.51 billion.
