title: [Dynamic tests with GN-RH L-dopa, clomiphene, HCG and HMG in normal adult men].
abstract: The plasma levels of gonadotrophins, androgens (expressed as testosterone) and 17beta-oestradiol in response to GnRH, L-dopa, clomiphene, HCG and HMG administration have been assayed by radioimmunological mehtods in 70 normal adult males. In keeping wih findings reported in the literature, the results obtained confirm the usefulness of dynamic stimulation with GnRH, clomiphene, and HCG in andrology for the purpose of evaluating the efficiency and integrity of the hypothalamic-pituitary-testicular system and of its individual glandular components. On the other hand, the administration of L-dopa and HMG does not appear to yield clinically useful findings.
