Quercetin Inhibits ROS-p53-Bax-caspase-3 axis of apoptosis and augments gonadotropin and testicular hormones in chronic unpredictable stress-Induced testis injury

Int. j. morphol; 39 (3), 2021
SUMMARY: A large body of evidence supports the protective role of the flavonol antioxidant compound quercetin in mammals. We tested the hypothesis that quercetin can protect against the hypothalamus-pituitary-gonadal (HPG) axis defect like a reduction in gonadotropins and testicular hormones and abnormal...
