[Changes in the seminiferous parenchyma of rams after experimental ischemia].
The changes induced by experimental ligature of a. testicularis and its effect on the parenchyma of the testes were studied in juvenile rams. Short-term ligature (four days) causes destructive changes on gonocytes and precursors of Sertoli's cells which show considerable vacuolization of cytoplasm. The later post-operative period is characterized by the cytolysis and caryolysis of all cells. In a period of three to four months there is fibration of the necrotically altered organ. Traumatic damage caused to the sexual gland leads to a disorder in the circulation of blood, resulting in the necrosis of all components of testicular parenchyma, except tunica albuginea.
