Polycystic ovaries are common in women with hyperandrogenic chronic anovulation but do not predict metabolic or reproductive phenotype.

Polycystic ovary syndrome (PCOS) is a heterogeneous disorder of unexplained hyperandrogenic chronic anovulation. Experts have recommended including the morphology and volume of the ovary in the diagnostic criteria for PCOS. We performed this study to determine whether there was an association between the morphology and size of the ovaries and markers of insulin sensitivity as determined by dynamic testing within women with PCOS or compared with a group of control women.
