Effects of sex hormone binding globulin capacity and pregnancy zone protein of treatment with combinations of ethinyl-oestradiol and norethisterone.
Sex hormone binding globulin (SHBG) and pregnancy zone protein (PZP) are two highly oestrogen-inducible serum proteins. SHBG capacity and PZP level were measured in 49 women treated with three different combinations of ethinyloestradiol and norethisterone. SHBG capacity and PZP were measured before and after 6 mth of treatment and both serum factors significantly increased during treatment for all three groups. PZP induction was found to be more sensitive and mainly to reflect the oestrogen component of a combined preparation while SHBG capacity was more sensitive to the modulating effect of the progestogen.
