microscope2By investigating the unique mechanisms of immunoregulation in the testis and the effects of inflammation and infection on male reproductive function, Associate Professor Hedger and his team wish to better understand the relationship between the male reproductive tract and the immune system. This will provide them with clues about autoimmune infertility, inflammation, and infections of the male reproductive tract, and may eventually hold the key to the development of male contraceptives and immunotherapeutics for transplant patients.
