[Preventive action of catecholamine and serotonin synthesis inhibitors and of adrenergic blockaders on the occurrence of the anovular syndrome in neonatally androgenized rats. I].

Administration of catecholamine synthesis inhibitors (alpha-methl-p-tyrosine) or serotonin (parachlorphenylalanine) simultaneously with testosterone propionate prevented the anovular sterility in the majority of the neonatally androgenized rats. Preventive action of adrenoblockers (droperidol and propranolol) on the effects of early androgenization were weak. The data obtained pointed to the participation of catecholamines and serotonin in the realization of the masculinizing action of androgen on the neuroendocrine centres of the gonadotropin hormones secretion control.
