Effects of osmolality on sperm morphology, motility and flagellar wave parameters in Northen pike (Esox lucius L.)

Original language description

Northern pike (Esox lucius L.) spermatozoa are uniflagellated cells differentiated into a head without acrosome, a midpiece and a flagellar tail region flanked by a fin structure. Total, flagellar, head and midpiece lengths of spermatozoa were measured and show mean values of 34.5, 32.0, 1.32, 1.17 um, respectively, with anterior and posterior widths of the midpiece measuring 0.8 and 0.6 um, respectively. The osmolality of seminal plasma ranged from 228 to 350 mOsmol kg-1 (average: 283.88 +/- 33.05). After triggering of sperm motility in very low osmolality medium (distilled water), blebs appeared along the flagellum. At later periods in the motility phase, the tip of the flagellum became curled into a loop shape which resulted in a shortening of the flagellum and a restriction of wave development to the proximal part (close to head). Spermatozoa velocity and percentage of motile spermatozoa decreased rapidly as a function of time post activation and depended on the osmolality of activ
