Male Infertility & Germ Cell Biology Laboratory
Professor Moira O'Bryan
We study sperm development and function and the causes of human male infertility.
Approximately 1 in 20 Australian men are infertile and for the majority of these individuals, there is no specific diagnosis. Sperm development is a fascinating process that requires the co-ordinated activation of thousands of genes. It involves stem cell renewal, meiosis, cell changes and complex post-translational mechanisms, which regulate sperm function. We use models of infertility and cell biology assays to define key proteins and pathways for fertility. This research has direct implications for the diagnosis of human infertility, and the development of therapies and contraceptives.
