Gene expression of growth factors in GLC and GCs (median + 95% CI). (A) AMH expression did not differ between PCO and control GCs. AMH was negligible in GLCs (****P < 0.0001). (B) AMHR2 expression did not differ between PCOS and control GCs. (C) FST (follistatin) expression did not differ between PCOS and control GCs and was higher in GCs than GLCs (****P < 0.0001, ****P < 0.0001). (D) INHBA was higher in PCO GCs compared with controls (*P < 0.05). (E) INHBB was higher in control and PCO GCs compared with control and PCOS GLCs (****P < 0.0001, ****P < 0.0001).
