Effects of mesencephalic lesion on testes, seminal vesicles and adrenal glands of albino rats.

The role of mesencephalic reticular formation on testicular structure, seminal vesicles, adrenal glands and kidneys of albino rats was investigated. Mesencephalic reticular formation lesions were produced using two epoxy-coated stainless steel electrodes. Electrolytic lesions resulted in atrophy of the testes, seminal vesicles and adrenal glands. The degree of atrophy was statistically significant in these organs (P < 0.01). However, there were no significant changes in the kidneys of lesioned animals. This study strongly suggests that the mesencephalic reticular formation influences the histomorphology of testes, seminal vesicles and adrenal glands.
