ABSTRACT Numerous randomised studies have reported pregnancy outcome in women who received acupuncture during their in vitro fertilisation (IVF) treatment cycle.
The objective of this study was to conduct a systematic review with meta-analysis of the trials of acupuncture during IVF treatment on the outcomes of clinical pregnancy and live birth rates.
Searches were conducted in MEDLINE, EMBASE, Cochrane Library, ISI Proceedings and SCISEARCH.
All randomised controlled trials that evaluated the effects of acupuncture compared with no treatment or sham acupuncture in women undergoing IVF-intracytoplasmic sperm injection treatment were included.
Study selection, quality appraisal and data extraction were performed independently and in duplicate. A sensitivity analysis was conducted where the meta-analysis was restricted to trials in which sham acupuncture was used in the control group. Meta-regression analysis was used to explore the association between study characteristics and pregnancy rates.
Thirteen relevant trials, including a total of 2500 women randomised to either acupuncture or control group, were identified. No evidence of publication bias was found (Begg's test, P = 0.50). Five trials (n = 877) evaluated IVF outcome when acupuncture was performed around the time of transvaginal oocyte retrieval, while eight trials (n = 1623) reported IVF outcome when acupuncture was performed around the time of embryo transfer (ET). Meta-analysis of the five studies of acupuncture around the time of egg collection did not show a significant difference in clinical pregnancy (relative risks [RR] = 1.06, 95% CI 0.82-1.37, P = 0.65). Meta-analysis of the eight studies of acupuncture around the time of ET showed no difference in the clinical pregnancy rate (RR = 1.23, 95% CI 0.96-1.58, P = 0.1). Live birth data were available from five of the eight studies of acupuncture around the time of ET. Meta-analysis of these studies did not show a significant increase in live birth rate with acupuncture (RR = 1.34, 95% CI 0.85-2.11). Using meta-regression, no significant association between any of the studied covariates and clinical pregnancy rate was found (P > 0.05 for all covariates).
Currently available literature does not provide sufficient evidence that adjuvant acupuncture improves IVF clinical pregnancy rate.

    ABSTRACT: Introduction The comprehensive review was to appraise the current evidence from both randomized and non-randomized trials by using both Chinese and western databases and to highlight the issues which could guide future trial design. Many infertile couples have chosen acupuncture as an adjunct when they undergo in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment. More than forty trials have emerged since the first clinical research published in 1999 explored the effects of acupuncture on the outcomes of IVF. However, the current evidence makes it difficult for clinical practitioners and patients to make a decision on whether to choose acupuncture as an adjunct when undergoing IVF or ICSI treatment. Methodology A total of thirty-three randomized and 5 non-randomized controlled trials were included in the review. Results Based on this comprehensive review and analysis of all the relevant trials, the authors identify the factors which have contributed to these inconsistencies, and which should be considered in the design of future studies. Discussion/conclusions These items included in the review could provide useful recommendations and guidelines, which will in turn promote better trial design and improve the evidence base for the use of acupuncture for IVF.

    ABSTRACT: The aim of this paper was to provide reliable evidence by performing a systematic review and meta-analysis for evaluating the role of acupuncture in assisted reproductive technology. All randomized controlled trials that evaluated the effects of acupuncture, including manual, electrical, and laser acupuncture (LA) techniques, on the clinical pregnancy rate (CPR) and live birth rate (LBR) of in vitro fertilization (IVF) or artificial insemination were included. The controlled groups consisted of no acupuncture and sham acupuncture groups. The sham acupuncture included sham acupuncture at acupoints, sham acupuncture at non- or inappropriate points, sham LA, and adhesive tapes. Twenty-three trials (a total of 5598 participants) were included in this paper. The pooled CPR from all acupuncture groups was significantly higher than that from all controlled groups, whereas the LBR was not significantly different between the two groups. However, the results were quite distinct when the type of control and/or different acupuncture times were examined in a sensitivity analysis. The results mainly indicate that acupuncture, especially around the time of the controlled ovarian hyperstimulation, improves pregnancy outcomes in women undergoing IVF. More positive effects from acupuncture in IVF can be expected if a more individualized acupuncture programs are used.

    ABSTRACT: The role of somatosensory stimulation (acupuncture and related techniques) as an adjunct to assisted reproductive technology (ART) has been hotly debated over the past decade. In the last 6 years there have been no fewer than 12 meta-analyses of 34 randomised controlled trials (table 1). Systematic and narrative reviews of the literature often report conflicting findings and opinions. Despite this controversy, subfertility remains one of the most common reasons that women consult an acupuncturist.47 Meta-analysis of acupuncture trials is often challenging due to methodological diversity, and this is especially true for in vitro fertilisation (IVF) due to marked differences in timing (treatment given during the follicular phase, at the time of oocyte retrieval and/or embryo transfer (ET), and/or as luteal phase support) and the variety of interventions including manual acupuncture, electroacupuncture (EA), transcutaneous electrical acupuncture point stimulation (TEAS) and laser acupuncture. Various outcome measures have been used ranging from biochemical pregnancy rate to live birth rate (LBR), depending on the duration of follow-up. LBR (‘take home baby rate’) is considered to be the ideal primary outcome measure and is clearly most important to patients. Interestingly, concordance between studies with respect to point location is relatively high. The acupuncture points targeted generally correspond anatomically to the segmental innervation of the uterus and ovaries, irrespective of whether the primary approach to point selection is traditional or neurophysiological. … [Full text of this article]
