Latest research found : Acupuncture really do nothing for IVF

How acupuncture works as a cure for infertility is still debatable.

Is this true? No, Not really......One research says

Latest research from Reprod Biomed Online
Acupuncture performed at the time of embryo transfer does not improve the pregnancy or live birth outcome after treatment.[1]

Patients undergoing true acupuncture had differing sensory experiences compared with patients in the sham arm.
