Product Licensing

The Population Council collaborates with pharmaceutical companies to develop, manufacture, and distribute contraceptives and other products to the global market. In keeping with the Council’s mission, these partnerships include provisions to ensure that products are offered to people in less-developed countries at public-sector prices.

The Council has developed and licensed some of the most widely used long-acting, reversible contraceptives in the world. To date, more than 120 million women worldwide have used Population Council–developed products for family planning, including the Copper T intrauterine device; Mirena®, the levonorgestrel-releasing intrauterine system; and the implants Jadelle® and Norplant®.

The Council has contraceptive and HIV prevention products in various stages of development. Products for which we are currently soliciting licensing partners include:
