2. FIGURE 1
Comparison of the serum IGF-1, IGFBP-3, GH, and insulin concentrations, and of the glucose/insulin ratio, of the different patient groups with those of the control group. Values are means ± SEM. IH = idiopathic hirsutism; FOH = functional ovarian hyperandrogenism; FAH = functional adrenal hyperandrogenism. ∗P <.001 vs. the control, IH, and FOH groups, by one-way ANOVA and the least significant difference test. †At least P <.05 vs. the control group, by one-way ANOVA and the least significant difference test.

3. FIGURE 2
Comparison of the activity of adrenal enzymes of the patient groups with those of the control group. Values are means ± SEM. The molar ratios of the increments in serum steroid levels in response to ACTH stimulation signify the following adrenal enzyme activities: overall P450c17α (A) = ΔA/ΔP ratio; 17-hydroxylase (B) = Δ17-OHP/ΔP ratio; 17,20-lyase (C and D) = ΔA/Δ17-OHP and ΔA/ΔF ratio; 21α-hydroxylase (E) = Δ17-OHP/ΔF; and 11β-hydroxylase (F) = ΔS/ΔF. IH = idiopathic hirsutism; FOH = functional ovarian hyperandrogenism; FAH = functional adrenal hyperandrogenism; 17-OHP = 17α-hydroxyprogesterone; P = progesterone. ∗At least P <.05 vs. the control group by one-way ANOVA and the least significant difference test.

4. FIGURE 3
Comparison of the activity of ovarian enzymes among the groups of hirsute patients. Values are means ± SEM. The molar ratios of the increments between baseline and day 1 in serum steroid levels in response to triptorelin signify the following ovarian activities: overall P450c17α (top) = ΔA/ΔP ratio; 17-hydroxylase (middle) = Δ17-OHP/ΔP ratio; and 17,20-lyase (bottom) = ΔA/Δ17-OHP. IH = idiopathic hirsutism; FOH = functional ovarian hyperandrogenism; FAH = functional adrenal hyperandrogenism; 17-OHP = 17α-hydroxyprogesterone; P = progesterone. ∗At least P <.05 vs. the IH and FOH groups by one-way ANOVA and the least significant difference test.
