2. FIGURE 1
Algorithm of 132 consecutive patients seen prospectively to determine the prevalence of idiopathic hirsutism. Patients with the polycystic ovary syndrome (oligoovulation, and hirsutism and/or hyperandrogenemia) and women with hirsutism and hyperandrogenemia but apparently normal ovulatory function, were considered as having functional androgen excess. If the diagnosis of idiopathic hirsutism is based solely on the presence of hirsutism and regular ovulation, regardless of androgen levels, then 29% of our total untreated hirsute population could be considered affected. However, only 17% of all hirsute patients can be diagnosed as having the disorder, if idiopathic hirsutism is defined as hirsutism, regular ovulation, and normal androgen levels. BBT = basal body temperature chart; P4 = progesterone level.
