BMI was positively correlated with MMP-9 (p < 0.001) and MMP-1 (p < 0.01) and negatively correlated with MMP-2 (p < 0.0001), MMP-10 (p < 0.001), MMP-12 (p < 0.005), ADAM-9 (p < 0.05), ADAMTS-5 (p < 0.05), and IGFBP-1 (p < 0.0001) in subjects with PCOS, as shown in Table 3 and Figure 2. This evidence concerns the gene MMP9 and polycystic ovary syndrome.
