[Comparison of 2 steroid parameters by means of the 3 phase test in hirsutism patients]

The excretion of the C19O2-fraction of 17-oxosteroids in urine (C) and the concentration of testosterone in serum (T) have been compared in 15 women with hirsutism during tests with suppression of the adrenals and the ovary and with stimulation of the ovary. The behaviour of both parameters seemed to be only qualitatively similar in all three phases of the tests. In one of the test phases a statistically significant correlation between the percentage of decrease or increase of C and T has been observed (First phase: r = 0.242; second phase; r = 0.457; third phase r = 0.392). The mean relative changes of C in the adrenal suppression phase was more distinct (P less than 0.002) than that of T. Both parameters seem to be of different diagnostic meaning.
