However, BMI, Mean arterial pressure (MAP), ovarian volume, serum LH, T and the LH/FSH ratio of the patients with PCOS were higher than the controls (BMI, 23.38 ± 3.87 kg/m2 vs. 21.71 ± 3.07 kg/m2; MAP, 90.90 ± 11.33mmHg vs. 85.41± 9.01mmHg; ovarian volume, 8.33 ± 3.79 cm3 vs. 4.82 ± 2.04cm3; LH,10.19 IU/L ± 7.66 vs. 4.28 ± 1.61 IU/L; T, 0.67 ± 0.29 vs. 0.42 ± 0.14; LH/FSH, 1.70 ± 1.18 vs. 0.63 ± 0.23; P< 0.05). Here, BRD2 is linked to polycystic ovary syndrome.
