Abstract:
The author investigated the influence of immobilization stress on spermiogenesis in rats. After 96 h immobilization, histological changes began to manifest in the form of a practically complete disappearance of the cell population of the wall of seminiferous tubule as well as a markedly increased number of cells with pathologic mitoses. Enzymological investigations have shown in particular groups (24, 48 and 96 h immobilization) various changes of activity (of acid and alkaline phosphatase, nonspecific esterase and glucose-6-phosphatase) which, after temporary negativity, became positive again in the last group.
