To date there is not a lot of research published on the treatment of endometriosis with Chinese medicine that meets the standard required for us to draw firm conclusions on efficacy. One review has analysed findings from 10 small trials that used acupuncture to treat endometriosis pain, and randomised controlled trials have examined the use of chinese medicine to prevent recurrence and to improve pregnancy rates after surgery. A large review has analysed the effect of acupuncture on dysmenorrhoea and is included here since pelvic pain from any source is considered to represent a blockage and must be addressed in a fertility  consultation.
