Patients with PCOS (n = 59) had significantly higher BMI (22.29 ± 1.26 vs. 23.12 ± 1.06), TESTO (0.40 ± 0.17 vs. 0.60 ± 0.24), LH/FSH (1.07 ± 0.56 vs. 2.39 ± 0.90), and AMH (4.2 ± 3.0 vs. 9.4 ± 4.8) than the control group (n = 56; P < 0.001; Fig. 3A). Here, PLOD1 is linked to polycystic ovary syndrome.
