To evaluate the effects of the combination of d-chiro inositol and alpha lipoic acid on menstrual cycles and insulin sensitivity in women with polycystic ovary syndrome (PCOS). Forty-one women with PCOS and 31 controls have been enrolled in the study. The menstrual cycle, BMI, homeostasis model assessment index (HOMA-I), and insulin secretion in response to an OGTT were evaluated before and after 6 months of treatment. During the observation period, the patients have been asked to not modify their diet and physical activity. The menstrual cycle length improved in 76.7% of the women. Ovulation was restored in 40%. During treatment, BMI significantly decreased (p<.002). The HOMA-I and insulin secretion were unchanged by treatment. However, when women were divided according to the presence of insulin resistance (IR; HOMA-I > 2.5), in those with IR the HOMA-I and the insulin secretion significantly decreased (p<.05 and p<.006). The association of d-chiro-inositol and alpha lipoic acid improves menstrual cycle length, restoring ovulation in the majority of women. Insulin sensitivity improved in women with IR only, confirming that in presence of IR the d-chiro-inositol has a role in restoring the insulin action overcoming the inactivity of epimerase in transforming myo-inositol to d-chiro inositol.
