Franik G, et al. - Researchers analyzed data of 76 PCOS (41 obese) and 67 Non-PCOS (40 obese) women in this cross-sectional study in order to analyze interrelations between estradiol/testosterone (E2/T) and estradiol/androstenedione (E2/A) indexes and nutritional status, insulin resistance among these patients. As per observation, nutritional status more affected the E2/A index than E2/T index. They noted the lower value of both indices in PCOS women with normal body mass. This suggests the relation of nutritional status with aromatase activity in PCOS.
