insulin resistance in women with polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is reproductive disorder and metabolic syndrome. Prevalence of insulin resistance in women with PCOS is from 44 to 70%, but IR is not present in all PCOS women. The PCOS phenotypes identified with the Rotterdam criteria Hyperandrogenism + PCO with ovulatory cycles (phenotypes Type C), and anovulation and PCO without hyperandrogenism (Phenotypes Type D) have modest or absent evidence for insulin resistance. We study a group of women with menstrual disorder and impaired fertility in our clinic and the aim of study is to evaluate the correlation of insulin resistance with different phenotype of PCOS according to Rotterdam/NIH criteria.
