Abstract
To evaluate the relationship between the secretion of gonadotropins and adrenal and rogens, patients with gonadal agenesis were evaluated by (a) administering human luteinizing hormone (hLH) for 5 days with or without estrogen pretreatment to agonadal patients who had prepubertal LH levels; (b) correlating circulating gonadotropin levels with adrenal androgens in 45 patients; and (c) comparing adrenal androgens with gonadotropins after long-term administration of estrogen or androgens. Results are as follows: (a) No alteration in serum concentrations of dehydroepiandrosterone (DHA), dehydroepiandrosterone sulfate (DHAS), estrone (E,), testosterone (T), or in excretion of urinary 17-ketosteroid (17 KS) occurred after the administration of hLH. (b) No clearcut relationship between endogenous level of LH or FSH and DHA or DHAS was demonstrated although a coincident increase of all hormones with age occurred, (c) Administration of estrogen to patients with gonadal agenesis did not affect their levels of DHA and DHAS although those patients given androgen developed higher DHAS, but not DHA, levels. Hence, increasing gonadotropin concentrations would not appear to be a primary etiologic factor in the maturation of the adrenal.
