A systematic review of 25 trials covering 4800 participants, suggests that acupuncture improves pregnancy rates in IVF. The authors calculated a pooled clinical pregnancy rate across all the acupuncture groups in 25 trials, of 44%. By contrast, the equivalent figure for the control groups was 33%.
Across 11 trials, the pooled live birth rate across the acupuncture groups was 38%, versus 29% across the control groups.
