Different swimming behaviors of sterlet (Acipenser ruthenus) spermatozoa close to solid and free surfaces
Original language description
Spermatozoa tend to swim near surfaces. Such attraction toward surface vicinity was approximated by the force-dipole theoretical approach and hydrodynamic modeling, but the physical parameters of surfaces have not usually been included in these models and their effect on sperm mobility remains unknown. In spermatozoa, changes in wave parameters, together with rotation around their longitudinal axis and circling appear when movement takes place close to surfaces. Here we show, by analysis of microscopy images (including high-speed video), a strong influence of the liquid-solid interface on sterlet spermatozoa motility characteristics compared with motility near the liquid-gas interface. Sperm cells swam at 16% lower velocity near a liquid-solid interface, rotating at a stable frequency of 25 Hz, each 180 degrees rotation corresponding to one beat cycle and circling clockwise (when observed from top). In case of spermatozoa close to a water-air interface, rotation and circling were spora
