A test with gonadotropin is a method of differential diagnosis of primary and secondary (i.e., caused by a violation of humoral regulation) lesions of the gonads. It is based on determining changes in the intensity of excretion of 17-ketosteroids and testosterone in the urine after the administration of human chorionic gonadotropin. An increase in the secretion of these hormones after the administration of gonadotropin indicates the secondary nature of the damage to the gonads.
If the secretion of hormones does not increase, this indicates a primary lesion of the gonads themselves. Thus, this test makes it possible to differentiate diseases caused by disruption of the hypothalamic-pituitary system and pathologies caused by damage to the gonads themselves.
