Abstract:A method is described by means of which fertilized sea urchin eggs can be re-fertilized at various intervals after the first insemination. During the nuclear division the possibility for additional sperm to enter the egg is diminished.Further experiments have indicated causal relationship of the breakdown of the cortical granules and the formation of the hyaline layer to the establishment of the block to polyspermy.
