✦ Synopsis

The effect of low temperature on the cortical actin system and polyspermy in sea urchin eggs was studied. Eggs cold-shocked at 3°C for 1 hour formed a cortical system of polymerized actin and were polyspermic when fertilized. These effects were completely reversible following a 7-20 minute recovery period at room temperature. The present data raises the possibility that actin, or components of the egg cytoskeleton, regulate sperm entry in sea urchin eggs.
