Plasma selenium levels in Turkish women with polycystic ovary syndrome

Objective(s): To evaluate selenium (Se) levels in serum and their relation with hyperandrogenism and insulin resistance (IR) in women with polycystic ovary syndrome (PCOS) and in control subjects. Study design: Women with any gynecological problem who presented to the Kahramanmaras Sutcuimam University Medical Faculty Gynecology and Obstetric Outpatient Clinic were invited to participate. Group 1 consisted of 36 cases with a diagnosis of PCOS according to the 2003 Rotterdam Consensus Criteria, and Group 2 (control group) consisted of 33 age- and BMI-matched healthy women. In all cases, serum total testosterone (tT), dihydroepiandrostenedione-sulfate (DHEAS), follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), insulin, glucose (mg/dL), total cholesterol (TC) (mg/dL), high density lipoprotein-cholesterol (HDL-C) (mg/dL), low density lipoprotein-cholesterol (LDL-C) (mg/dL), triglyceride (TG) (mg/dL) and Se levels were measured. Results: The level of FSH was significantly lower, and the levels of LH, E2, tT, and DHEAS were significantly higher in group 1 than in group 2 (p < 0.05). The hirsutism score was significantly higher among PCOS women compared to the control group (p < 0.05). Although insulin levels and HOMA-IR were markedly increased in the PCOS group compared to the control group, the differences were not significant (p > 0.05). The plasma Se level was significantly lower in PCOS women compared to the control group (p < 0.05). When we combined the all women in two groups, regarding them as one group (combined group, n = 69), a negative correlation between Se and LH and tT was present (p < 0.05). Conclusion(s): Our results show decreased plasma concentrations of Se and a negative correlation between Se and LH, tT in women with PCOS. These results indicate that Se May play a role in the pathogenesis of PCOS related with hyperandrogenism. (C) 2013 Elsevier Ireland Ltd. All rights reserved.
