title: Biochemical basis for evaluating oral contraceptives.
abstract: Oestrogens stimulate and increase HDL cholesterol concentration while progestogens decrease it; quite marked differences in effect on HDL can be demonstrated between the various oestrogen-progestogen combinations. Similar differences can be shown in their effect upon blood coagulation factors and upon the renin-angiotensin aldosterone axis. It is suggested that the selection of an oral contraceptive, in terms of cardiovascular risk, can be made from a consideration of comparative biochemical data.
