This technique for fertility became highly accepted after the American Society for Reproductive Medicine published the study "Influence of Acupuncture on the Pregnancy Rate in Patients Who Underwent ART" in the Fertility and Sterility®
journal (April 2002). Their findings suggest acupuncture seems to increase the pregnancy rate considerably, by about 42.5%.
There are also many articles on acupuncture and infertility. The show Sex and the City
even aired an episode where one of the main characters received acupuncture for infertility.
