PCOS is complicated and affects a woman's menstrual cycle, fertility, hormones, insulin production, circulatory system, and appearance. In a small study involving 20 women, the groups that participated in moderate exercise three times a week or who received low-frequency electro-acupuncture fare better over a 16-week period than the control group that did neither. In electro-acupuncture, the needles are attached to a device that send gentle electronic pulses through them, stimulating the body points associated with ovaries even more. The two groups receiving treatment, those exercising and those who received acupuncture, had lower levels of muscle sympathetic nerve activity, which common means of monitoring the syndrome. The women who received acupuncture treatments had regular menstrual cycles as well, which is a good sign that hormonal element of the syndrome is improving.
