With normal fasting glucose levels, these PCOS patients had decreased SHBG levels than the control (21.1 ± 8.3 vs. 48.1 ± 7.8 nmol/L, p < 0.05), the insulin levels higher (24.4 ± 17.2 vs. 7.9 ± 6.7 uU/ml, p < 0.05) and the homeostasis model assessment index for insulin resistance (HOMAIR) higher (5.21 ± 3.73 vs. 1.59 ± 0.65 units, p < 0.05) (Table 1). This evidence concerns the gene SHBG and Insulin resistance.
