LDHB and polycystic ovary syndrome: Additionally, CHO showed a significant positive correlation with the expression of LDHB (r = 0.35, p = 0.04), as shown in Fig. 7C. Elevated LDHB levels in individuals with higher cholesterol could reflect an increased reliance on anaerobic glycolysis, which might be associated with metabolic stress or lipid dysregulation in PCOS patients.
