Twenty-nine patients with polycystic ovary syndrome (PCOS) and 30 normal women had lipoprotein lipid and androgen profiles compared after a 12-h fast. Both PCOS and normal women were evaluated in the proliferative phase of the cycle. PCOS patients had higher serum LH to FSH ratios [2.0 +/- 1.3 (+/- SEM) vs. 0.6 +/- 0.1), higher testosterone (T; 66 +/- 5 vs. 33 +/- 2 ng/ml), higher free T (1.1 +/- 1 vs. 0.4 +/- 0.02 ng/dl), and higher dehydroepiandrosterone sulfate (291 +/- 28 vs. 140 +/- 12 micrograms/dl) levels, and lower T-estrogen-binding globulin-binding capacity (1.5 +/- 0.2 vs. 2.2 +/- 0.1 micrograms/dl) than normal women (all P less than 0.05). The PCOS patients had higher mean serum triglycerides [122 +/- 11 (+/- SEM) 63 +/- 3 mg/dl] and very low density lipoprotein cholesterol levels (24 +/- 2 vs. 13 +/- 1 mg/dl), but lower high density lipoprotein cholesterol levels (43 +/- 2 vs. 58 +/- 2 mg/dl; P less than 0.05). While PCOS patients were heavier and more sedentary and their diets were higher in saturated fat and lower in fiber (P less than 0.01, respectively), the differences in lipoprotein lipid concentrations could not be attributed to body weight. T-estrogen-binding globulin-binding capacity correlated with high density lipoprotein cholesterol in PCOS patients (r = 0.42; P = 0.025) after adjusting for weight. We conclude that hyperandrogenemia in women may result in a male pattern of lipoprotein lipid concentrations. These findings suggest that PCOS patients may have increased atherogenic potential.
