Abstract
At fertilization the sea urchin egg undergoes a dramatic structural reorganization of its surface. Within the first few seconds there is a depolarization of the egg plasma membrane and this is followed by a transient increase in intracellular Ca++. The elevated Ca induces the exocytosis of cortical granules and the resulting fertilization membrane helps make the egg refractory to further insemination.
