Quantitative detection using a spectrophotometer indicated that the ROS intensity in the PCOS-GH group (1.10 ± 0.21) was significantly lower than that in the PCOS-C group (2.78 ± 0.35) (P < 0.05), but no difference with non-PCOS controls (1.00 ± 0.21) (P > 0.05). This evidence concerns the gene GH1 and polycystic ovary syndrome.
