Abstract:The influence on the fertility of sea urchin spermatozoa of homologous and heterologous jelly substance was investigated.It was found that the jelly substance diminishes the fertilizing capacity of the sperm. This also diminishes the incidence of polyspermy. These effects of the jelly substance are in keeping with previous results which showed that the jelly coat in situ or in solution acts as an inhibitor of fertilization.
