Potential role of the acrosome of sturgeon spermatozoa in the fertilization process

Original language description

Sturgeon gametes are unique in that their spermatozoa possess acrosome whereas their eggs are perforated by numerous micropyles. Thus the function of acrosome is unclear. The acrosomal reaction of Acipenser ruthenus spermatozoa was induced by solution containing Ca2+ and high pH. The rate of affected spermatozoa was evaluated using Soybean Trypsin Inhibitor-Alexa conjugate fluorescent staining. Fertilization and hatching test proofed necessity of acrosome integrity for fertilization. Increasing percentage of spermatozoa with disrupted acrosome highly decreased percentage of hatching, in spite of electron microscopy verification that the spermatozoa bearing such disrupted acrosomes were able to reach the micropyle. In addition the significant positive correlation between the ability of spermatozoa to induce acrosomal reaction by activation solution and sperm fertilizing ability suggested that spermatozoa, which are able to activate the acrosomal reaction, are more successful in fertiliz
