The fine structure of spermatozoa in hypo thermic rats






Tsitologiya 25(3): 334-337

The fine structure of spermatozoa in hypo thermic rats

The cooling of rats up to +28.degree. and +20.degree. C induced considerable ultrastructural alterations of the plasma membrane, nucleus, acrosome and mitochondria of ejaculated spermatozoa. There is a correlation between the level of the artificial hypothermia and the number of changed cells. The higher percentage of pathological spermatozoa was revealed in the ejaculate of cooled rats with narcosis. The possibility of secondary ultrastructural alterations of spermatozoa in the posthypothermal period is discussed.
