One of the most fundamental questions of fertilization is how do sperm locate eggs? In many animals and lower plant groups, sperm are guided by chemo-attractants released from eggs. In this issue of Nature Cell Biology, Kaupp and colleagues now examine the very early events of this process in the sea urchin Arbacia punctulata.
