title: [Ultrastructure of the spermatozoa of rats undergoing hypothermia].
abstract: It has been found that the cooling of rats up to +28 degrees and +20 degrees C induced considerable ultrastructural alterations of the plasma membrane, nucleus, acrosome and mitochondria of ejaculated spermatozoa. The data obtained show 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 without narcosis. A possibility of the secondary ultrastructural alterations of spermatozoa in the posthypothermal period is discussed.
