BRD2 and ovarian disorder: After adjusted for age, infertility types, infertility duration, FSH, LH, T, ovarian surgery and ovarian disorders, correlations between the number of oocytes retrieved and overweight (OR: 0.925, 95%CI: 0.876–0.977, P = 0.005), high TC (≥5.18 mmol/L) (OR: 1.103, 95%CI: 1.046–1.162, P = 0.001), TG (OR: 1.137, 95%CI: 1.083–1.193, P < 0.001), LDL-C (≥3.37 mmol/L) levels (OR: 1.162, 95%CI: 1.093–1.235, P < 0.001), low HDL-C (OR: 1.103, 95%CI: 1.048–1.160, P < 0.001) were all significant (Table 2).
