For a sperm to fertilize an egg, the sperm must first mature in a man's epididymis. Now, an international team of researchers has identified a chain of events in which a protein secreted by the testis travels in the luminal fluid, binds to a receptor on the epididymis to induce its differentiation and secretion of a second protein that matures the sperm and enables each sperm to be motile in females.
