In a recent study conducted by Homerton University Hospital in London 160 female patients undergoing IVF were placed into two groups; one group having four sessions of acupuncture over the course of the IVF cycle and the other having standard IVF without acupuncture. 

Results showed that 46.2% of patients in the acupuncture group became pregnant, versus 21.7% of patients in the standard IVF group. 

These results add to many previous trials showing that acupuncture combined with IVF significantly increases the chances of achieving a pregnancy. The difference with this study is that it particularly looked at acupuncture sessions over the course of the IVF cycle as opposed to just on the day of embryo transfer - preparation of the uterine environment is key to success.
