After the FSH injection, inhibin B levels increased significantly in the PCOS women and this was independent of the progesterone treatment (Exp 1 and Exp 2) (p < 0.05 and p < 0.001 respectively) with no significant difference between the two experiments; however, in the controls (Exp 3), inhibin B levels did not increase after the FSH injection (Figure 2B). Here, BRD2 is linked to polycystic ovary syndrome.
