The AMPPA network as a successful model for public-private or private-private partnership

In 1997, the Rockefeller Foundation and the Ernst Schering Research Foundation (a subsidiary of Schering AG, Germany, on a non-profit basis) mounted a multi-year global collaborative effort, involving a network of top-level research institutions to intensify research on the regulation of the male reproductive system with special emphasis on post-testicular activity, utilizing new approaches in molecular pharmacology (application of molecular pharmacology for post-testicular activity (AMPPA) network). The new venture proved a success as a public-private sector partnership, as a collaborative scientific program, and as an approach to identify new targets applicable and suitable for drug finding for male fertility regulation.
