title: Effect of oral contraceptives on markers of hyperandrogenism and SHBG in women with polycystic ovary syndrome.
abstract: BACKGROUND
  This randomized study's aim was to compare the effect of four oral contraceptives (OCs) containing 30 mcg of ethinylestradiol (EE) and different progestogens [drospirenone, (DRSP), chlormadinone acetate (CMA), desogestrel (DSG), gestodene (GSD)] on biochemical and hormonal parameters of hyperandrogenism and sex hormone-binding globulin (SHBG) in women with polycystic ovary syndrome (PCOS).
  
  
  METHODS
  Forty women with PCOS (age 16-35 years) were recruited and randomly assigned to one of four treatment groups of 10 women each, treated, respectively, with 3 mg DRSP/30 mcg EE (Yasmin, Bayer Shering), 2 mg CMA/30 mcg EE (Belara, Grunenthal), 75 mcg GSD/30 mcg EE (Minulet, Wyeth Lederle) and 150 mcg DSG/30 mcg EE (Practil 21, Organon Italia). Blood samples were obtained on day 6-8 of the control cycle and day 6-8 of the third treatment cycle for assay of the following hormones: androsteredione (A), total testosterone (T), free T, SHBG, dehydroepiandrosterone sulphate (DHEAS).
  
  
  RESULTS
  In all groups, mean concentrations of free T, total T and A dropped by 40-60%, and concentrations of DHEAS dropped by 20-50%. Formulations with DRSP and CMA caused a greater reduction of androgens and a progressive increase in serum concentrations of SHBG than those with DSG and GSD.
  
  
  CONCLUSIONS
  Clinical studies need to be performed to determine effects of these OCs upon clinical signs of hyperandrogenism.
