Acupuncture and Exercise Decrease Symptoms of PCOS

Polycystic ovary syndrome (PCOS) is associated with high muscle sympathetic nerve activity. Below is the asbtract o the study and results. Although the study was completed in rodents, it may have application to further human study and treatment.

"Twenty women with PCOS were randomly allocated to one of three groups; low-frequency electro-acupuncture (n=9), physical exercise (n=5) or to an untreated control (n=6) group during 16 weeks. Biometric, hemodynamic, endocrine and metabolic parameters were measured. Results: Low-frequency electro-acupuncture (P = 0.036) and physical exercise (P = 0.030) decreased MSNA burst frequency compared to the untreated control group. Low-frequency electro-acupuncture group reduced sagittal diameter (P = 0.001), while physical exercise group reduced body weight (P = 0.004) and body mass index (BMI) (P = 0.004) as compared to the untreated control group. Sagittal diameter was related to MSNA burst frequency (Rs = 0.58, P < 0.005) in the EA group. No correlation was found for BMI and MSNA in the exercise group. There were no differences between the groups in hemodynamic, endocrine and metabolic variables. Conclusions: For the first time we demonstrate that low-frequency EA and physical exercise lowers high sympathetic nerve activity in women with PCOS. Thus, treatment with low-frequency EA or physical exercise with the aim to reduce MSNA may be of importance for women with PCOS."
