this study shows that an lhrh agonist has no direct effect on the morphology of the seminiferous tubules in the absence of the pituitary gland and strongly suggests that the atrophy observed in the testis after lhrh agonist treatment in intact animals is mediated by the lhrh agonist-induced changes in luteinizing hormone secretion and/or direct action of the peptide on leydig cells .
