Resumo

PURPOSE: To determine whether tension in the spermatic cord of rats causes lesions in the testis, epididymis or vas deferens. METHODS: Forty Wistar rats were randomly allocated into four groups. A traction force of 1.6 Newton (N) in group I and 1 N in group II was applied to the right spermatic cord. Group III was the sham, and group IV served as the control. RESULTS: Testicular lesions occurred on the right side in 66.7% of the rats and on the left side in 46.1% of the rats. The testes showed a decreased number of Sertoli cells, necrosis and a decreased number of germ cells in the seminiferous tubules. Anatomopathological changes in the vas deferens were not identified. There was no decrease in the thickness of the muscle wall of the vas deferens. In the right epididymis, 71.8% of the animals showed a reduction and 5% showed an absence of intraluminal sperm. In the left epididymis, 37.5% of the rats showed a reduction. The volume and the final testicular weight of the right side in group IV was different from those in the other groups. CONCLUSIONS: Anatomopathological lesions were found in the testis and epididymis.(AU)
