To explore the differences in the hormone imbalance and characterize the roles of AR and FOXL2 in patients with PCOS, we analyzed the PCOS-related hormone levels in follicular fluids and the expression of AR, FOXL2, and FOXL2 downstream genes, including CYP19A1, FST (follistatin), and STAR (steroidogenic acute regulatory protein) in human primary GCs. This evidence concerns the gene STAR and polycystic ovary syndrome.
