A researcher at Kansas University Medical Center has received a five-year, $7.5 million grant to oversee a nationwide effort to study male contraceptives.The grant from the National Institutes of Health will establish the Interdisciplinary Center for Male Contraceptive Research and Drug Development. The goal is to develop reversible male contraceptives including further work on Gamendazole, a compound developed in recent years at KU that is designed to cause temporary infertility by stopping sperm production.The center will be directed by Joseph Tash, professor of molecular and integrative physiology at KUMC, and associate director Gunda Georg, who previously worked at KU and is now chairwoman of medicinal chemistry at University of Minnesota.Other collaborators in the project include Duke University, the University of California-San Francisco, Robert Wood Johnson Medical School, and the University of Medicine and Dentistry of New Jersey.
