Identification and characterisation of phosphorylation events taking place during human sperm capacitation

Male infertility affects one in every twenty Australian males and one third of all infertile couples worldwide. The most common cause of human infertility is not a failure to produce sperm, but a failure of these cells to express a normal capacity for fertilization. The cause of this loss of functional competence is unclear. We are going to use our technical expertise in proteomics to characterize the molecular pathways responsible for the defective sperm function seen in infertile patients.
