Figure 10. Relationship between the levels of reduced glutathione (GSH) and total glutathione (tGSH) in the blood and the number of mature oocytes. (A) Significant negative correlation between GSH levels in the blood and the number of mature oocytes, indicating increased consumption of systemic antioxidants during the metabolically demanding oocyte maturation process. (B) Significant negative correlation between tGSH levels in the blood and the number of mature oocytes, reflecting a reduction in overall antioxidant capacity due to heightened oxidative stress and metabolic activity. r=Spearman’s correlation coefficient. Significant differences are noted when p-value<0.05.
