Both actual acupuncture and simulated (sham) acupuncture produced similar results in women with polycystic ovary syndrome (PCOS), according to a recent study. PCOS is a condition affecting approximately six percent of women of reproductive age and is characterized by missed or irregular menstrual periods, an increased ratio of luteinizing hormone to follicle-stimulating hormone, and insulin resistance. PCOS is often a cause of infertility. Previous studies have suggested that acupuncture may be effective in restoring regular menstrual periods and ovulation, and achieving pregnancy. The current study, funded in part by NCCAM, was published in The Journal of Clinical Endocrinology and Metabolism.
