The average basal luteinizing hormone (LH) levels, the LH to FSH ratio, and the serum testosterone concentrations in PCOS patients were elevated more than in the control group (7.5 ± 3.59 vs. 5.4 ± 2.77, 1.4 ± 0.87 vs. 0.9 ± 0.55, and 2.2 ± 1.18 vs. 1.5 ± 0.85, respectively). Here, PLOD1 is linked to polycystic ovary syndrome.
