30% of infertility cases fall into the "unexplained" category. After all the expensive tests are done, it is frustrating to be told, "We know something is wrong, but we don't know what it is." Many infertility specialists believe that a common cause of unexplained infertility is stress and anxiety. In Chinese medicine, Liver qi stagnation is the primary agent causing emotional disorders such as anxiety, depression and stress. Liver qi stagnation is the most common diagnosis in the treatment of unexplained infertility. Acupuncture and Chinese medicine have a very good track record for relaxing people and treating pain and stress. Scientific studies done in several countries prove that acupuncture can affect the production of neurotransmitters in the body and can actually increase serotonin and endorphin levels.
