BRD2 and polycystic ovary syndrome: Although FSH remained unchanged across groups, the elevated LH/FSH ratio in PCOS mice (0.6 ± 0.1 vs. 0.3 ± 0.1) was attenuated by low-dose BSTJF (0.4 ± 0.1, P < 0.05), high-dose BSTJF (0.4 ± 0.1, P < 0.01), and FPS-ZM1 (0.4 ± 0.1, P < 0.01), indicating improved ovarian reserve.
