Is accupuncture good for infertiliy?

Yes. It's been said to improve uterine and ovarian bloodflow and help the communication of the pituitary with the uterus and ovaries. Also one of the other effects is an amazing calming and balancing feel it has on the person during the infertility treatment and after.
Yes. Dr chin provided an exceptional answer. The world health organization classifies acupuncture infertility treatments under "diseases, symptoms or conditions for which the therapeutic effect of acupuncture has been shown but for which further proof is needed".
