title: Tonic and dynamic gonadotropin secretion in depressive and normothymic phases of affective disorders.
abstract: Baseline follicle stimulating hormone (FSH) and luteinizing hormone (LH) plasma levels and their responses to luteinizing hormone releasing hormone (LHRH) stimulation were investigated in 72 patients who met Research Diagnostic Criteria for affective disorders and in 72 healthy volunteers. Fifty-six patients were examined during a depressive phase and 16 during a normothymic phase. LH-FSH basal levels were significantly lower in postmenopausal depressed and normothymic women than in controls. In fertile women and men, concentrations of the two gonadotropins were also lower in patients than in controls, but the phenomenon did not generally reach statistical significance. LHRH-induced LH rises were lower in postmenopausal and fertile depressed and normothymic women than in controls, while FSH rises were reduced only in postmenopausal depressive women in both depressed and normothymic phases. The impairment underlying the gonadotropin secretory deficiency remains to be elucidated.
