    • Abstract

       

      Sperms were isolated fromBufo melanostictus testes, by a simple technique of differential centrifugation. β-Galactosidase, N-acetyl β-D-glucosaminidase, α-L-fucosidase, neuraminidase and acid phosphatase activities were detected in the sperms. All the sugar components of the jelly glycoprotein were released when toad jelly glycoprotein was treated with sperm suspension. These facts suggest that the sperm glycosidases are involved in the penetration of jelly by the sperm at the time of fertilization.
