Ovulatory and Metabolic Effects of d-Chiro-Inositol in the Polycystic Ovary Syndrome

Abstract
Women with the polycystic ovary syndrome have insulin resistance and hyperinsulinemia, possibly because of a deficiency of a d-chiro-inositol–containing phosphoglycan that mediates the action of insulin. We hypothesized that the administration of d-chiro-inositol would replenish stores of the mediator and improve insulin sensitivity.
