The aim was to investigate oxidative stress indicators in the blood of women with PCOS without and with metabolic syndrome (MS) and their dependency on lipids, comparing with healthy women. To our knowledge, this is the first study on this topic.


This was a cross-sectional study, and blood tests performed were double-blind. Within 3 months, 205 PCOS patients, from whom 55 also had MS, and 65 healthy women (control) were recruited. Malondialdehyde (MDA) was assessed as an important oxidative indicator, and superoxide dismutase (SOD), total antioxidant activity (TAA), vitamin C (VC), vitamin E (VE) and retinol (RET) as antioxidative indicators. Their correlation with features of MS was analyzed including their dependency on lipid pattern.


SOD, TAA, VE and RET in the PCOS group and PCOS + MS group were lower and MDA higher than in the control group (p < 0.05). SOD, VE and RET were the lowest in PCOS + MS group (p < 0.05). Thus, patients in this group had the highest oxidative stress levels but the lowest antioxidative capacity. SOD and TAA significantly decreased with increase of triglycerides (TG) and LDL-C in the PCOS + MS group (p < 0.05), but without dependency on HDL-C. Stepwise multiple linear regression analysis confirmed the different expression of oxidative stress in the three groups and decrease of SOD from control to PCOS group to PCOS + MS group, being associated with an increase of TG.


MS can accelerate the oxidative stress process in patients with PCOS and decrease the antioxidative capacity. The decreased antioxidant capacity in PCOS with MS is related to increased TG and LDL-C.
