dc.description.abstractOwing to the problem of male infertility in the domesticated shrimp Penaeus monodon, this study was conducted to reveal the morphological events of an acrosome reaction (AR) of sperm of this highly valuable species. The AR observed in an in vitro incubation of sperm with egg water (EW) and that during actual spawning was compared. Under transmission and scanning electron microscopy, sperm taken from the female thelycum was composed of a posterior main body, a central cap and an anterior single spike. Upon contact with EW, the sperm underwent two phases of AR: acrosomal exocytosis and spherical mass formation. The former was composed of a degeneration of the spike, swelling of the cap region and rupture of the acrosomal pouch. The latter began with polymerization of materials within the subacrosomal region and ended with re-configuration of the subacrosomal region into an electron-dense spherical mass. The AR of the sperm observed during spawning revealed similar morphological events, with degeneration of the spike upon contact with the vitelline envelope and formation of the spherical mass while penetrating into jelly material produced by protruding cortical rods. The results suggest the presence of AR inducers derived from the vitelline envelope and cortical rods of the egg. This study forms the basis for an evaluation of infertility regarding to AR in the domesticated P. monodon male.en_US
