One acupuncture and fertility study in the U.S. where 51% of the women who received acupuncture treatments with their in-vitro fertilization treatments became pregnant, while only 36% of those without acupuncture treatments became pregnant. In the German in-vitro fertilization study (consisting of 160 women) – half were given acupuncture and half were not. Of the ones that received acupuncture, 30 became pregnant. Of the women who did not receive acupuncture, only 21 became pregnant.
There have been instances where conception occurred from using only a combination of acupuncture and herbal medicines and without traditional medical interventions such as in-vitro fertilizations. However, since these events are isolated and happened outside of a test environment, no one can say that if the conception was due to acupuncture and herbs or whether the conception was simply a matter of luck.
