While estradiol, prolactin, and thyroid-stimulating hormone (TSH) levels were similar in both groups, the follicle-stimulating hormone (FSH) level was statistically significantly lower and the ­luteinizing hormone (LH) level was statistically significantly higher in the PCOS group compared to the control group (p=0.303, p=0.201, p=0.649, p=0.011, and p<0.001, respectively). This evidence concerns the gene PLOD1 and polycystic ovary syndrome.
