[Cyto-physiologic indicators of the status of the reproductive organs of male rats after 7-day immobilization stress and 7-day hypokinesia].
The effect of repeated immobilization (7 days for 2.5 hours a day) and 7-day hypokinetic exposure on the reproductive organs of male rats of Wistar strain was investigated. In immobilized rats the weight of reproductive organs (testes, epididymidis and seminal vesicles) was reduced. In animals of both subgroups the spermatozoid concentration in the epididymal suspension was lowered and the relative content of spermatozoids with morphologically abnormal heads in suspension smears was increased. Cytological analysis of cell elements of the spermatogenic epithelium revealed a slight decrease in the number of spermatogonia, spermatocytes and Leydig's cells. In all experimental animals the number of multinuclear sexual cells of essentially every generation was significantly increased. It is concluded that the above stressogenic conditions produce stronger changes in reproductive organs than space flight per se.
