TCM acupuncture, irrespective of treatment timing, provided significant clinical benefits for women with primary dysmenorrhea, with reductions in pain severity, duration, secondary menstrual symptoms and analgesic intake.
Conclusion of this research: acupuncture treatment reduced menstrual pain intensity and duration after three months of treatment and this was sustained for up to one year after trial entry. The effect of changing mode of stimulation or frequency of treatment on menstrual pain was not significant. This may be due to a lack of power. The role of acupuncture stimulation on menstrual pain needs to be investigated in appropriately powered randomised controlled trials.

The Cochrane review found there is insufficient evidence to demonstrate whether or not acupuncture or acupressure are effective in treating primary dysmenorrhoea, due to the large volume of low-quality studies.
