SOD1 and endometriosis: In our study, we assessed oxidative stress biomarkers critical for antioxidant defense, including SOD, GPx, Vit E, and 8-iso-PGF2α.[45,46] Lower 8-iso-PGF2α levels indicate reduced oxidative stress, potentially linked to endometriosis pathogenesis and ectopic endometrial cell growth.[47] GPx protects the cell membranes from oxidative damage.
