FOXL2 and polycystic ovary syndrome: 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.
