title: [Importance of determining gonadotropin levels in the serum in secondary amenorrhea].
abstract: On the basis of the results of the analysis of FSH, LH, and prolactin values in the serum of patients with secondary ammenorrhea, four groups of patients were formed: group 1 with low values of both gonadotropin hormones, group 2 with low FSH and high LH values, group 3 with high FSH and high LH values, and group 4 with the basdal gonadotropin values within normal. The use of functional tests proved helpful in the differentiation of the causes of amenorrhea. The use of the LH-RH test is of particular significance in the differentiation of the degree of changes in patients from group 1 and 4. To determine adequate therapy, the determination of estrogen in patients from group 1 and 3 is imperative. A successful treatment of secondary amenorrhea depends on its duration and a timely detection of its causes.
