Description
| - The aim of this study was to investigate the response of Russian sturgeon (Acipenser gueldenstaedtii) sperm to external cations (Na+, K+, Ca2+, and Mg2+) and their susceptibility on the induction of motility and swimming behavior. An in vitro spermatozoa motility assay was used by a computer-aided Motion-Analysis system. Sperm motility was inhibited by 60 mm NaCl (similar to 140 mOsm/kg) and 0.7 mm KCl solutions (similar to 21.4 mOsm/kg). The Ca2+ and Mg2(+) ions were not able to inhibit spermatozoa motility. By contrast, Na+ within a limited concentration range (between 45 and 55 mm) was able to reverse the inhibitory effect of K+ at the critical concentration (0.7 mm). Ca2+ and Mg2+ were also able to reverse the K+-mediated spermatozoa motility restriction at concentrations starting at 0.01 and 0.1 mm, respectively. These results provide evidence for the role of K+ in suppressing spermatozoa motility, and suggest that Ca2+, Mg2+, and possibly Na+ trigger motility in Russian sturgeon sperm.
