Correlation between urinary testosterone or estrogen excretion levels and interstitial cell-stimulating hormone concentrations in normal postmenopausal women.

The purpose of the present study was to find out whether there is a correlation between the urinary levels of testosterone or of estrogens (estrone and estradiol) and ICSH urinary concentration in normal postmenopausal women. Examination of 35 normal subjects at different postmenopausal ages (from one year to over 10 years after menopause) showed a highly significant inverse correlation between ICSH and testosterone urinary excretion levels (coefficient of correlation "r" equals minus 0.548), but none between the urinary estrogen excretion levels and ICSH urinary concentrations.
