Levels of total antioxidant capacity and 8-hydroxy-2′-deoxyguanosine of serum and follicular fluid in women undergoing in vitro fertilization: focusing on endometriosis

This study was designed to evaluate the levels of oxidative stress (OS) markers, total non-enzymatic antioxidant capacity (TAC) and 8-hydroxy-2′-deoxyguanosine (8-OHdG) in the serum and follicular fluid (FF) of patients undergoing in vitro fertilization (IVF). The impact of these biomarkers on IVF outcome was also analysed. Samples were obtained from 61 patients (age: 36.40 ± 4.99 years; BMI: 22.54 ± 2.46; infertility: 3.7 ± 2.5 years [mean ±...
