[Basal and gonadotropin releasing hormone-stimulated gonadotropin secretion in patients with chronic uremia].

In 11 patients with chronic uremia both the basal and stimulated levels of LH and FSH in serum were determined by RIA. After renal transplantation the investigations were repeated in 2 cases. The basal levels of LH were unphysiologically increased whereas FSH was found in the normal range. The stimulation of LH by GnRH was adequate in 6 patients and in 5 there was no response. As a result of renal transplantation there was a drop of LH in serum. It is supposed that the unphysiological increase of LH in patients with chronic uremia is the cause for the disturbances of the menstrual cycle.
