The PCOS women showed statistically significant increase in serum BPA levels as compared to healthy women (p = 0.0046). The BPA level was also significantly associated with the clinical, hormonal, metabolic and haematological parameters as follows: waist circumference p = 0.027, BMI p = 0.039, TST p = 0.001, blood glucose fasting p = 0.001, blood glucose −1 h p = 0.032, blood glucose −2 h p = 0.005, serum total cholesterol p = 0.011, triglycerides p = 0.011, insulin fasting p = 0.002, HOMA-IR p <0.0001, QUICKI p = 0.0009, HCT p = 0.048 and MCV p = 0.011. Here, INS is linked to polycystic ovary syndrome.
