Changes in the flagellum morphology of intact and frozen/thawed Siberian sturgeon Acipenser baeri sperm during motility

Popis výsledku v původním jazyce

Morphological investigations on the changes in flagellar beating was carried out on native (taken from the milt) and thawed sperm of the Siberian sturgeon Acipenser baeri (Brandt). Immediately after activation, the pattern of flagellar wave formation anddistribution was the same in native and thawed sperm but, after 27-42 s, depending on the samples, the thawed flagella showed asymmetric and poorly developed waves. The swimming trajectories recorded during 1-s exposure were much shorter in thawed thanin native sperm after 26-28 s motility.In native sperm, the flagella remained in the same axis as the head during the entire motility course,while the head of thawed sperm showed a right angle after 47 s. It is concluded that the freezing/ thawing procedure induces some alteration in the dynamics of flagellar beating in many sperm, but these sperm still show progressive displacement. Therefore, the chang in morpgology of the flagellum during motion is a parameter that should be taken int
