A long-acting, highly effective contraceptive method called the levonorgestrel intrauterine system (LNG-IUS) was first approved for use almost thirty years ago. Since then, it has become popular and widely used in high-income countries. However, until recently, the high cost of existing products has limited availability of the method in low-resource settings. Now, new and more affordable LNG-IUS products are becoming available. In 2015, USAID convened a new working group comprised of a diverse group of donors, manufacturers, research and service delivery partners to help accelerate introduction of the method. Through this platform, FHI 360 and other members contributed to the development of a global learning agenda – a series of research questions that donors and implementing agencies agreed are priorities to evaluate the potential impact of the LNG-IUS. Working group members then implemented a simple but innovative approach to making limited research dollars go farther in addressing the learning agenda questions.
