The purpose

The main aims of this study are: - to investigate and compare the effects of long lasting use (59 weeks) of vaginal and oral contraceptives on androgen secretion, insulin and glucose metabolism, lipid profile, and serum levels of SHBG and hs-CRP in women with PCOS. - to compare the metabolic effects of oral and vaginal combined contraceptives and to find out whether oral or transvaginal contraceptive can be recommended to a particular group of women, for example in women with increased metabolic risks. - to clarify whether the unfavourable effects of combined contraceptives diminish with time (after use of one year).
