In Slopien et al. study they found no difference in glucose and insulin levels between obese PCOS patients and their BMI and age matched control group but only test ester on and LH levels were higher in PCOS group.12 In Kebapcilar’s research, WBC, HOMA IR, fasting glucose level, insulin and MPV levels were significantly higher in PCOS group.11 In our study we observed no significant difference in glucose, insulin, WBC, HOMA IR and MPV levels between groups so we assume that the difference observed in Kebapcilar’s study might be due to obese patients with PCOS. The gene discussed is INS; the disease is polycystic ovary syndrome.
