It sounds a bit strange, what is the relationship between needle in women with pregnancy? But research shows that acupuncture can improve pregnancy if done right before or after embryos are placed in the uterus.

"Acupuncture requires the placement of very thin needles at specific points on the body to try to manage pain and reduce stress. In fertility treatments, acupuncture can be expected to increase blood flow to the uterus, relax the cervix and prevent the emergence of stress hormones that can make the uterus more hard for the embryo to stick, "said Eric Manheimer, the leader of this analysis and a researcher at the University of Maryland School of Medicine.

But a surprising discovery has not yet been proven, and only just a theory of how and why acupuncture might work. However, some fertility specialists say they expect that this way is not expensive and simple treatment may ultimately prove useful in addition to traditional methods.

Although no evidence, but according to Dr. William Gibbons, who runs the fertility clinic in Baton Rouge, Los Angeles, said no problem to try and be handled more seriously. In addition more doctors are trained for it.

This analysis led by Eric Manheimer was funded by a federal agency, the National Center for Complementary and Alternative Medicine. The result was announced in the British Medical Journal (BMJ).

Poll analysis involving 1366 women in the United States, Germany, Australia, and Danish, the artificial insemination program. Sperm and egg cells in the laboratory to arrange a meeting at which the embryo is formed and then inserted back into the womb.

Women randomly assigned to receive self insemination, insemination with acupuncture during the planting day embryos, or implantation plus fake acupuncture, the needles are placed too shallow or in a place that has no effect.

Individually, only three of the studies found benefit from acupuncture, three showed a tendency to gain, and one found no benefit. When the results of smaller studies be polled, the researchers found pregnancy increases to 65% for women given acupuncture.

But a study led by Dr. Zev Rosenwaks, director of infertility treatment at New York-Presbyterian Hospital / Weill Cornell Medical Center, reported finding no acupuncture can help with pregnancy. Even so, he added that acupuncture is not dangerous.

Dr. Ann Treviño, a family physician 37-year-old, who is also pregnant believe acupuncture benefits. She has three times failed pregnancy by using artificial insemination before trying acupuncture.

"I've read about acupuncture, probably like everyone else on the internet. I'm just trying to do whatever possible to improve our opportunities," she said. "With acupuncture, I felt very warm and relaxed, when the embryos enter."
