Abstract

The results of seven gonadotropin releasing hormone (GnRH) loading tests are presented with special respect to the changes of melatonin level. The tests were carried out after a withdrawal bleeding triggered by progesterone (100 mg for 5 days) and plasma FSH, LH, prolactin and melatonin level were determined. The initial melatonin values were between 3.9 and 35.7 pg/ml and were in inverse ratio with the basal gonadotropin levels. In the case of reactive hypophyseal response the melatonin level decreased in every case in inverse ratio with the increase of gonadotropins. In one case, after the GnRH administration there was no increase in gonadotropin production and at the same time the melatonin secretion remained unchanged. According to our examinations the melatonin secretion during the GnRH loading test showed a good correlation with the changes of gonadotropins.
