Acupuncture involves placing very thin needles at specific points on the body to try to control pain and reduce stress. In fertility treatment, it is thought to increase blood flow to the uterus, relax the cervix and inhibit “fight or flight” stress hormones that can make it tougher for an embryo to implant, Manheimer said.
The analysis pools results from seven studies on 1,366 women in the United States, Germany, Australia and Denmark who are having in vitro fertilization, or IVF. It involves mixing sperm and eggs in a lab dish to create embryos that are placed in the womb.
Women were randomly assigned to receive IVF alone, IVF with acupuncture within a day of embryo transfer, or IVF plus sham acupuncture, in which needles were placed too shallowly or in spots not thought to matter.
Individually, only three of the studies found acupuncture beneficial, three found a trend toward benefit and one found no benefit. When results of these smaller studies were pooled, researchers found that the odds of conceiving went up about 65 percent for women given acupuncture.
