THE prevention of polyspermy in sea urchin eggs is accomplished in two steps: a “fast” block, occurring within a few seconds of the entry of the fertilising sperm, and a “slow” block, associated with the cortical reaction (compare refs 1–4 with 5 and 6). Results presented here confirm the existence of the fast block and demonstrate that it is caused by the… CONTINUE READING
