[Disorders of spermatogenesis in chronic emotional stress in rats]

The experiments on rats demonstrated that chronic emotional stress led to spermatogenesis impairment. The animals were put into restrainers and subjected to subcutaneous electrical stimulation 3 hours daily for 7 days. As a result of this stress the weight of thymus significantly decreased and weight of adrenal glands increased. Also there was a tendency of testes and seminal vesicles to weight decrease. Light microscopy showed significantly more plugs of degenerated spermatids and spermatocytes in seminiferous tubules of stressed animal tested in comparison with control rats. Spermatogenesis index was also reduced in experimental group. The present study showed that germ cells injury took place at the stage of spermiogenesis.
