Abstract


OBJECTIVE
To investigate the relationship between serum dehydroepiandrosterone sulfate (DHEAS) or free testosterone (FT) levels and aging.
METHODS
One hundred and thirty one women without androgen excess symptoms such as oligomenorrhea or amenorrhea or hirsutism were recruited for measuring serum DHEAS, FT levels by radioimmunoassay. A P-value <0.05 was considered to be significant statistically.
RESULTS
The levels of DHEAS were 211.39+/-33.01 microg/dL (twenties, n=10), 127.99+/-11.79 microg/dL (thirties, n=31), 94.30+/-7.49 microg/dL (forties, n=57) and 71.79+/-5.71 microg/dL (over fifties, n=33) respectively (mean+/-SE, P<0.001). The levels of FT were 3.98+/-0.94 pg/ml (twenties, n=10), 3.37+/-0.47 pg/mL (thirties, n=31), 2.68+/-0.30 pg/mL (forties, n=57) and 1.97+/-0.28 pg/mL (fifties, n=33) respectively (mean+/-SE, P=0.030). Mean value declining of DHEAS (r=-0.48865, P<0.0001) was bigger than those of FT (r=-0.29334, P<0.0007).
CONCLUSION
Both DHEAS and FT levels decline with age and DHEAS decreases more steeply than FT.
