Brief Summary

Hyperinsulinemia and insulin resistance play a key role in the pathogenesis of polycystic ovary syndrome (PCOS). Insulin resistance is significantly associated with the long-term risks of metabolic syndrome and cardiovascular disease. Acupuncture with electrical stimulation has in rats with dihydrotestosterone (DHT)-induced PCOS been shown to improve insulin sensitivity. Whether these findings can be translated into women with PCOS has not been investigated. Therefore, this study aims to evaluate whether acupuncture improves insulin sensitivity, ovulation rate and quality of life in women with PCOS. Our hypothesis is that acupuncture with combined manual and low-frequency electrical stimulation of the needles improves insulin resistance, induces ovulation and improves quality of life.

Detailed Description

This is a prospective observational study. A total of 112 women with PCOS and insulin resistance will be recruited and randomized into two groups according to their body mass index (BMI), i.e. normal weight (BMI=18.5-23Kg/m2) group and overweight or obese (BMI > 23Kg/m2) group1. The acupuncture treatment will last for six months, 3 times per week, 30 minutes per treatment. The primary outcome is changes in insulin sensitivity from baseline to after 6 months of acupuncture treatment measured by OGTT.

Exclusion Criteria

1. With other endocrine disorders such as hyperprolactinemia (defined as two prolactin levels at least one week apart 25 ng/mL or greater or as determined by local normative values), nonclassic congenital adrenal hyperplasia (17-hydroxyprogesterone <3nmol/L), and androgen secreting tumors.

2. Patients with FSH levels > 15 mIU/mL. A normal level within the last year is adequate for entry.
