The 10 articles featured in this collection, published in the journal Global Health: Science and Practice, offer insights on the introduction of early infant male circumcision (EIMC) services in Cameroon, Lesotho, Senegal, Swaziland, Tanzania, and Zimbabwe. The collection also highlights important considerations for policy, service delivery, cost, and demand creation as countries plan for and begin implementing EIMC services to help sustain the gains made by voluntary medical male circumcision programmes.
