Comparative study on ultrastructure and motility parameters of spermatozoa of tetraploid and hexaploid Siberian sturgeon Acipenser baerii

Original language description

Siberian sturgeon is supposed to be species of functionally tetraploidy (4n) producing diploid (2n) sperm. Large-scale screening of ploidy levels revealed one hexaploid (6n) male specimen producing triploid spermatozoa. This sperm was compared in terms of ultrastructure and motility features. All evaluated morphometrical characteristics showed significantly higher values in spermatozoa of 6n in comparison with 4n Siberian sturgeon males. Mean values of velocities at the beginning of activation differedhighly significant between spermatozoa of 6n and 4n males in time 15 and 30 s post activation. Nevertheless their velocities did not show significant differences in 45 and 60 s post activation. It was supposed that the bigger head of 6n male spermatozoainhibited motility at the beginning of activation, but later the longer flagellum and bigger midpiece with higher number of mitochondria can balance the increased sizes of heads in spermatozoa movement of male with higher ploidy level.
