Analysis of Pro- and Antioxidant Status in Women with Endocrine Infertility

Abstract

The aim of our study was to identify the changes in the indicators of lipid peroxidation (LPO) and antioxidant defense (AOD) in women with endocrine infertility. Methods and Results: The study included 358 women of reproductive age. Based on clinical and laboratory data, two groups were formed: the control group (CG) and the main group (MG). CG consisted of 61 healthy fertile women (mean age of 22±2.3 years). MG consisted of 297 women (mean age of 26±5.6 years) with endocrine infertility. The blood levels of antioxidant parameters (total antioxidant activity [TTA], SOD activity, α-tocopherol and retinol) and primary/secondary products of LPO (conjugated dienes [CD], ketodienes and conjugated trienes [KD-CT], and thiobarbituric acid reactants [TBARs]) were determined using spectrophotometric and fluorometric methods. The levels of sex hormones and cortisol were determined by radioimmunoassay and EIA. In MG, we found a significant increase in the blood levels of total lipid, DB, CDs, KD-CT, and TBARs, compared to CG. The results of a comparative analysis of the AOD parameters showed a significant increase in the total AOA level by 31% in MG, while the levels of α-tocopherol and retinol significantly decreased by 22% and 15%, respectively, compared to CG. In women of MG, the serum level of prolactin increased by 2 times. Conclusion: The results obtained reflect the adaptive and disadaptive mechanisms of LPO-AOD participation in the formation of female infertility of endocrine origin. The complex changes in the LPO-AOD system (increased levels of the substrates of oxidation and all intermediates of the LPO process amid falling values of the AOD parameters) indicate the presence of OS in women with endocrine infertility.
