Mechanism of action/effects of androgens on lipid metabolism.
The strongest predictors of cardiovascular disease in women have been shown to be diabetes, high blood pressure, cigarette smoking, and, to a lesser degree, hypertriglyceridemia. The difference in risk between men and premenopausal women has been explained by the following widely held hypothesis: androgens lower plasma concentrations of high-density lipoprotein (HDL), particularly the HDL-2 subfraction, and increase plasma concentrations of low-density lipoprotein (LDL). In contrast, estrogens have the opposite effect, raising plasma concentrations of HDL, particularly HDL-2, and lowering plasma concentrations of LDL. After the menopause, it is believed that the protective effect of estrogens in women is lost and the incidence of heart disease rises to equal that in men. This paper provides a brief review of the effect of endogenous and exogenous androgens on lipoprotein metabolism in men and women, and considers the relevance of these findings to the choice of progestogens used in oral contraceptive preparations.
