OBJECTIVE: To investigate the relationship between 8 endocrine-disrupting chemicals in the serum and insulin resistance in patients with polycystic ovary syndrome (PCOS).
METHODS: This study was conducted among 60 patients with PCOS, including 23 with insulin resistance (PCOS-IR) and 37 without insulin resistance (PCOS-NIR), and 29 non-PCOS women seeking medical attention for infertility or menstrual disorder (control group). The serum levels of 6 phthalic acid esters (PEAs), bisphenol A (BPA) and octylphenol (OP) were measured in all the subjects.
RESULTS: The levels of PAEs, BPA and OP showed no significant differences between PCOS patients and the control group (P>0.05). The serum level of OP was significantly lower in patients PCOS-IR than in those with PCOS-NIR (47.89 ng/ml vs 60.24 ng/ml, P<0.05).
CONCLUSION: PEAs and BPA do not produce obvious effect on the pathogenesis of PCOS or contribute to insulin resistance, but OP may play a role in insulin resistance in PCOS patients.
