Abstract

Estrogen and progestins have been used by millions of women as effective combined oral contraceptives. Oral contraceptives (OCs) modify surrogate markers such as lipoproteins, insulin response to glucose, and coagulation factors, that have been associated with cardiovascular and venous risk. Ethinyl-Estradiol (EE) exerts a stronger effect that natural estradiol (E2) on hepatic metabolism. New progestins with high specificity have been designed to avoid interaction with other receptors and prevent androgenic, estrogenic or glucocorticoid related side-effects. The risks and benefits of new progestins used in contraception depend upon their molecular structure, the type and dose of associated estrogen, and the delivery route. The lower impact of E2-based combinations on metabolic surrogate markers may result in an improved safety profile, but only clinical outcomes are relevant to assess the risk. Large surveillance studies are warranted to confirm this hypothesis.
