The effects of two sequential oral contraceptive preparations, Sequostat (6 days ethinylestradiol 0.05 mg, 15 days ethinylestradiol 0.05 mg + norethisterone acetate 1.0 mg) and Sequence-Ovosiston (9 days mestranol 0.1 mg, 12 days mestranol 0.08 mg + chlormadinone acetate 2.0 mg) on triglycerides, total cholesterol, HDL- and LDL-Cholesterol, glucose tolerance, total plasma proteins, plasma protein fractions, plasma transaminases, gamma-glutamyl-transferase, alkaline phosphatase and antithrombin III were studied in two groups of 46 and 29 young women respectively. Investigations were performed prior to the hormonal intake and after treatment for 3, 6 and 12 months. In nearly all parameters studied significant but minimal changes could be demonstrated which in most cases showed a minor degree in the Sequostat-group, while Sequence-Ovosiston exerted a less effect on glucose tolerance. A significant increase of HDL-cholesterol and a reduction of LDL/HDL-cholesterol relation could be demonstrated at least in the first six months, resulting from the estrogen dominance of the contraceptives.
