Hypothalamic-pituitary-gonadal function in relation to liver function in men with alcoholic cirrhosis

Serum concentrations of oestrone, oestradiol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and sex hormone-binding globulin (SHBG) were significantly (P less than 0.01) raised in men with alcoholic liver cirrhosis (no. = 42) compared with age-matched controls (no. = 20). No significant difference was observed when comparing serum testosterone concentrations. Patients were divided into three groups in accordance with the severity of liver cirrhosis, using biochemical and clinical criteria. Patients with the best-preserved liver function (no. = 11) and patients with moderately affected liver function (no. = 18) had significantly (P less than 0.05) raised serum concentrations of testosterone, FSH, and LH when compared with both controls and patients with severely affected liver function (no. = 13). Serum concentrations of testosterone, FSH, and LH in the latter group showed no significant differences from the controls. Serum concentrations of oestrone and oestradiol were significantly (P less than 0.05) increased in all patient groups, and serum oestrone increased with decreasing liver function. No significant differences were observed concerning SHBG concentrations in the three groups of patients. Dexamethasone suppression did not change the concentration of testosterone significantly, but oestrone and oestradiol concentrations decreased significantly (P less than 0.01) in controls and patients. In patients, but not in controls, a significant (P less than 0.01) increase in FSH and LH concentrations was observed after dexamethasone suppression. The mean percentage increase of FSH and LH was higher the greater the severity of liver cirrhosis.
