Conclusions
Acupuncture, PCOS
Acupuncture can improve not only the emotional changes in SF-36 scale scores and ChiQOL scale scores, but also lipid metabolism. There is a correlation between emotional change and lipid metabolism. Meanwhile, acupuncture can regulate the changes of serum Ca, K, and Cl ions, which may be another mechanism of acupuncture in the treatment of PCOS. Moreover, sham acupuncture may not be completely ineffective, which may be related to the improvement in some aspects of patients with PCOS through the placebo effect.
