“Changes of estradiol levels during the menstrual cycle correlated positively with the changes of ascorbic acid levels and total antioxidant plasma status (p<0.05).”
“Furthermore, estradiol levels correlated positively with ascorbic acid levels (p<0.05, r<0.5), ascorbic–dehydroascorbic acid ratio (p<0.05, r<0.5), and total antioxidant plasma status (p<0.05, r<0.8) in all menstrual phases.”
