Motility initiation of sterlet sturgeon (Acipenser ruthenus) spermatozoa: Describing the propagation of the first flagellar waves
Original language description
In the present study, for the first time in fish spermatozoa, we describe the precise chronology of motility initiation of sterlet (sturgeon) sperm from completely immotile flagella to regular full wave propagation. The successive activation steps were investigated by high-speed video microscopy, using specific experimental situation, where sperm motility initiation was delayed in time up to several seconds (10 +/- 2.68 seconds). Starting from fully immotile, the flagellum shows some trembling for a brief period, soon followed by appearance of the first real bend (so-called "principal bend") with a large wave amplitude 4.28 +/- 0.65 mu m, then by the "reverse bend," the latter presenting a lower (P < 0.05) wave amplitude (1.14 +/- 0.32 mu m). This couple of first bends formed at the basal region begins to propagate toward the flagellar tip but gradually fades when reaching the midflagellum, wherein consequently the sperm cell remains nonprogressive. This behavior repeats several times
