Abstract
Serum proteins of 30 women were estimated before, and 6 months after, regular intake of contraceptive pills (0.1 mg mestranol and 5 mg megestrol). A highly significant rise of increasing degree was observed for α2-macroglobulin, lipoproteins, transferrin, plasminogen, α1-antitrypsin, thyroxine-binding globulin (cortisol), and ceruloplasmin. The immunoglobulins were unchanged, but albumin, haptoglobins, and orosomucoid showed a highly significant decrease. The fall of orosomucoid and haptoglobins was greater than during pregnancy, while the rise of α1-antitrypsin, α2-macroglobulin, lipoproteins, and transferrin was less. It is concluded that the metabolic effects of contraceptive steroids has not been properly explored. This study implies that these metabolic effects are only in partial agreement with the alterations occurring during normal pregnancy.
