PLOD1 and polycystic ovary syndrome: In PCOS women, we observed significantly higher BMI (p = 0.001), AMH levels (p < 0.001), LH levels (p = 0.02), LH/FSH ratio (p < 0.001), DHEAS (p < 0.001), and androstenedione levels (p < 0.001), whereas age (p < 0.001), 25(OH)D (p = 0.019), FSH (p < 0.001), and estradiol levels (p < 0.001) were lower compared to healthy women without PCOS.
