FIGURE 1 Number of patients with serum hyperandrogenemia as shown by increased levels of A (□), DHEAS (■), and total T (TT) ( ) either permanently or in the first phase (days 2–5) or the second phase (days 22–25) determinations.

FIGURE 2 Number of patients with transient hyperandrogenemia as shown by phase-related increased levels of A (□), DHEAS (■), and total T (TT) ( ), considered separately for patients with ovulatory and delayed or anovulatory cycles. Fertility and Sterility 1998 70, 664-670DOI: (10.1016/S0015-0282(98)00258-1)

FIGURE 3 Regression between first-phase (I) (days 2–5) and second-phase (II) (days 22–25) determinations of DHEAS (n = 48, r = 0.681, P < 0.001). Both the regression line and the 95% confidence interval for the mean of individual observations are presented. Individual observations are shown for patients with ovulatory cycles (•) and delayed or anovulatory cycles (▿). Fertility and Sterility 1998 70, 664-670DOI: (10.1016/S0015-0282(98)00258-1)
