Pregnancy outcomes of women randomized to receive real versus placebo acupuncture on the day of fresh or frozen-thawed embryo transfer.

INTRODUCTION: Acupuncture is commonly used in various aspect of Western medicine in recent years including in-vitro fertilization (IVF) treatment. Although there are many clinical trials of acupuncture in IVF and the Cochrane meta-analysis did not find benefit of adjuvant acupuncture for IVF, there is no report on the pregnancy outcomes of women who had received acupuncture during their IVF treatment.

OBJECTIVES: To compare the pregnancy outcomes of women randomized to receive real versus placebo acupuncture during their IVF treatment.

METHODS: A retrospective chart review was performed on the 212 women with on-going pregnancies after receiving real or placebo acupuncture by sterile disposable stainless steel needles or Streitberger's placebo needles to the acupoints before and after the embryo transfer on the day of fresh or frozen-thawed embryo transfer. The pregnancy outcomes were obtained from the Hospital Authority Clinical Management System for deliveries in the public sector or from a self-returned questionnaire if those in the private sector.

RESULTS: No significant differences were found between the demographics of the two groups including their age, gravida, parity and the duration of subfertility. Maternal adverse outcomes including gestational diabetes and hypertensive disorder were comparable for the real acupuncture group (35.3% and 4.4% respectively) and the placebo acupuncture group (39.7% and 5.5% respectively). None of the patients had placenta accreta. The preterm delivery (<37 weeks gestation) rate in the real acupuncture group (23/86, 26.7%) was similar to that in the placebo acupuncture group (25/97, 25.8%). No statistical significant difference was found in the mode of delivery. There were no significant differences between the two groups for Apgar scores and birthweight.

CONCLUSION: Acupuncture during IVF treatment does not influence pregnancy outcomes.
