The influence of body weight on lipoprotein lipids in patients with polycystic ovary syndrome.

Lipoprotein lipid and androgen profiles were compared after a 12-hour fast that involved 13 women with polycystic ovary syndrome and 13 who did not have the syndrome. All women were matched for percent ideal body weight. As expected, patients with polycystic ovary syndrome had significantly higher luteinizing hormone--to--follicle-stimulating hormone ratios, higher testosterone levels, higher free testosterone levels, higher dehydroepiandrosterone sulfate levels, and lower testosterone-estradiol-binding globulin binding capacity than the other women. Patients with polycystic ovary syndrome had significantly higher mean serum triglyceride levels, very-low-density lipoprotein cholesterol levels, and lower high-density lipoprotein cholesterol levels. Differences in body weight do not explain the male pattern of lipoprotein lipid concentrations in women with polycystic ovary syndrome. The association of hyperandrogenism with lipoprotein lipid abnormalities should be evaluated in regard to the influence of endogenous sex steroids on differences between the sexes in incidence of cardiovascular disease.
