Hypothalamic-pituitary function in patients of 6 selected groups of amenorrhea was evaluated by performing premarin test. Selected amenorrheic patients were divided into 6 groups of Turner's syndrome(5), adrenogenital syndrome(3), Sheehan's syndrome(4), moderate hyperprolactinemia(3), severe hyperprolactinemia(9) and functional oligoamenorrhea(9) the diagnoses of which were performed according to modified our own protocol for management of amenorrheic patients. As control 20 normally cycling women in mid follicular phase determined by their symptothermal charts during last 6 months designed by WHO were compared. The premarin test which is one of the tests evaluating the hypothalamic-pituitary function by the principle of negative and positive feed back effect's of estrogen was performed by injecting 20 mg of premarin in volus intravenously. The levels of serum LH before, 24, 48, 72, 96 and 120 hours after injection of premarin were measured by double antibody technique radioimmunoassay the reagents of which were supplied by WHO. The results were as follows: 1. Both negative and positive feed back effects by exogenous estrogen were well preserved even in the patients of gonadal dysgenesis although the baseline levels were much higher than normal. 2. In the patients of Sheehan's syndrome one could observe the minimal response of feed back effect in the case with minimal pituitary function. 3, Androgens in adrenogenital syndrome and prolactin in hyperprolactinemia may suppress mainly the positive feed back effect rather than the negative one. The suppressive effect can be abolished by proper treatments which can eliminate those suppressive hormones. 4. This premarin test may be beneficial for predicting the result of clomiphene in ovulation induction.
