Positive Clinical and Hormonal Effects of Ethinylestradiol Combined With Drospirenone (EE/DRSP) in Women With Polycystic Ovary Syndrome (PCOS): Impact of Body Weight and Relevance to Hyperandrogenism
Clinically, polycystic ovary syndrome (PCOS) is a heterogeneous disorder of functional
androgen excess and the features of PCOS can run through a spectrum of severity. The
optimal modality for long-term treatment of PCOS should positively influence androgen
synthesis, sex hormone binding globulin (SHBG) production, insulin sensitivity, the lipid
profile, and clinical symptoms including hirsutism and irregular menstrual cycles. Combined
oral contraceptives have been a key component of the chronic treatment of women with PCOS;
improving androgen excess and regulating menstrual cycles. The effect of OCs on ovarian
folliculogenesis significantly decreases androgen production. This mechanism was confirmed
in both healthy women and women with PCOS. In obese patients with PCOS, it is likely that
the suppression of androgen production is not as significant. It is thus possible to
hypothesize that the effects of OCs in PCOS could be dependent on body weight and what is
needed is a head-to-head comparison. The aim of this study is to compare the effect of 6
months of a low-dose oral contraceptive regimen of 24/4 DRSP 3 mg/EE 0.02mg/levomefolate
calcium 0.451 mg on androgen profiles, cardiometabolic measures, B-vitamin status, and
menstrual cycle regulation in three groups, normal (BMI 18-24.9 kg/ m2) overweight (BMI
25-29.9 kg/ m2) and obese (BMI 30-35 kg/ m2) women with PCOS.
