A body of clinical evidence for acupuncture is presented on the topic of acupuncture administered for IVF or ICSI that indicates acupuncture has a significant treatment effect on clinical pregnancy and birth rate when conducted at varied time points. Research is ongoing and is not conclusive.


A 2018 systematic review and meta-analysis found acupuncture to have a significant treatment effect in improving the birth rates of subfertile women undergoing IVF or ICSI.


A summary of previous acupuncture reviews from 2009 to 2017 found acupuncture had a beneficial treatment effect on clinical pregnancy rate. However, according to GRADE assessment guidelines, the scientific methods of the studies included in this review need to be improved.


It is recommended that future acupuncture research should explore the impact of acupuncture administration during ovarian stimulation. The aim should be to improve embryo and blastocyst quality, rather than focus on acupuncture post fertilisation.


According to the British Acupuncture Council, Acupuncture may be a suitable treatment option to help reduce stress and anxiety levels for women suffering with subfertility.


Research articles on acupuncture indicate that the effectiveness of acupuncture may be dose-dependent, that is a sufficient number of acupuncture treatments are required over an adequate period of time.

What you should know about acupuncture clinical evidence

A 2018 comprehensive systematic acupuncture review and meta-analysis investigated the effects of acupuncture on subfertile women in the UK during in vitro fertilisation (IVF) or intra-cytoplasmic sperm injection (ICSI).1 A total of 3,188 subfertile women from 12 randomised controlled UK trials were included in this latest investigation. There was substantial heterogeneity (I2 70.1% P=0.000). A random effects model was applied.

What did the research find?

According to the British Acupuncture Council, significantly improved the live birth rate of subfertile patients undergoing IVF or ICSI (birth rate: RR = 1.36, 95% CI 1.09–1.69, P=0.006).

Why is this acupuncture clinical evidence important?

In the UK, the overall birth rate following assisted reproduction is only 21% to 22% (fresh and frozen transfer). The birth rate varies and decreases with age and the type of transfer.

What this means

Live birth rate can be considered the most important measure of success for subfertile people undergoing assisted reproductive treatment. Through research and reviews, acupuncture has been shown to have a significant treatment effect on live birth rates, indicating that acupuncture may complement an IVF or ICSI cycle.

What is different about this new systematic acupuncture review and meta-analysis?

Acupuncture research articles did not just focus on trials with a limited number of acupuncture treatments around the time of egg collection only or embryo transfer only.3 This systematic review was able to include studies where women had additional acupuncture treatments. Electroacupuncture was also incorporated in this review whereas it was not included in a systematic review from 2013.4 Live birth rate was an outcome measurement where sufficient data was available.

What have other acupuncture research articles indicated?

An overview of systematic reviews from 2009 up to 2017 (that does not include the most recent systematic review above) found that acupuncture given at the time of egg collection and embryo transfer improved clinical pregnancy rates. The authors did not find a treatment effect for live birth rates when acupuncture was administered around egg collection only or embryo transfer only. This evidence was graded as low quality, which means that the true effect of acupuncture administration could be substantially different from this overview’s findings. The inconclusiveness of the clinical evidence base in this overview reflects the inadequacy of the scientific methods applied so far to evaluate IVF or ICSI and acupuncture. Recommendations for the future included a focus on acupuncture during the ovarian stimulation phase to influence follicular development and egg maturity, rather than treating women post fertilisation.

Further Research Articles on Acupuncture for IVF or ICSI Outcomes in the UK

The primary outcomes of some systematic reviews and meta-analyses indicate that there are no significant treatment effects of acupuncture on clinical pregnancy rate.3,4,9* However, the primary outcomes of other systematic reviews do show a benefit.1,10 ,11,12* These reviews demonstrate either a possible significant treatment effect11 or a treatment effect of statistical significance for improved rates of clinical pregnancy.1,10,12* One interesting characteristic of the studies included in the systematic reviews where an effect was found is that acupuncture was not just focused around the time of embryo transfer only. The samples of subfertile women undergoing an IVF or ICSI cycle also received acupuncture treatment at various time points during the treatment cycle. This indicates that acupuncture may be more effective with additional treatment prior to the day of embryo transfer and after embryo transfer. More research is required.


One recently published trial from Australia is not included in the reviews discussed above.6 It is the largest randomised controlled trial so far of IVF or ICSI with acupuncture. Technical issues, for example regarding the undertreatment of women with acupuncture (See Acupuncture sessions guide), and its sham control group, (See Discussion points for researchers: Control methods) make the conclusions difficult to relate to routine clinical practice.7,8

Acupuncture During Ovarian Stimulation

A 2018 RCT in China involving 169 subfertile women looked specifically at the impact of having acupuncture during the ovarian stimulation phase of an IVF or ICSI cycle. This experimental study found acupuncture improved ovarian blood supply and, in turn, both biochemical and clinical pregnancy rates. Live birth rate was not an outcome measurement in this trial. The clinical pregnancy rate was 52.6% (acupuncture group) v 33.3% (sham acupuncture group) and 32.8% (observational group). The researchers recommended that future experimental research should incorporate a larger sample of women.17

The conclusions of several systematic reviews indicate that the effectiveness of acupuncture may be dose-dependent, that is an appropriate strategy is needed with a sufficient number of acupuncture sessions over an adequate period of time.9*,12*,13


Can acupuncture improve emotional wellbeing during an IVF or ICSI cycle?

Assisted reproduction treatment can be stressful and anxiety provoking. Interventions to support the psychological impact of subfertility and fertility treatment should be offered, so that a patient can make an informed decision and a choice regarding an appropriate stress and anxiety management strategy that may help them. A study indicated that acupuncture treatment can reduce stress and/or anxiety and increase women’s ability to cope with the IVF process.18 A systematic acupuncture review that also included this study found that traditional acupuncture could be an effective strategy to alleviate stress and anxiety experienced by subfertile women.19

New research in progress

There are at least three systematic reviews registered in PROSPERO on this topic. These systematic reviews (listed below 1-3) aim to investigate the impact of acupuncture in women with poor ovarian response, update the effects of acupuncture on IVF, and explore the effect of acupuncture on hormonal markers.

Discussion points for Acupuncture researchers

Registration of a systematic review protocol

Only two systematic reviews were registered.3,4 It is preferable for authors of systematic reviews to register their research protocol with PROSPERO, the international prospective register of systematic reviews. This permits transparency and helps assessment of the outcomes based on systematic acupuncture review processes.

Risk of bias of systematic reviews primary outcomes

*denotes high risk of bias

The risk of bias of systematic reviews evaluated in this research article was assessed using the ROBIS tool. Two systematic reviews were found to be potentially at a high risk of bias regarding an acupuncture treatment effect. These were Qian et al12* which found a beneficial treatment effect, and Shen et al9* which reported no beneficial treatment effect (although the statistical interpretation is incorrect, and a significant treatment effect was evident).

Exploration of statistical heterogeneity

Subgroup analysis is generally recommended if variability is present resulting from the systematic review process and meta-analysis. A subgroup analysis should be considered and pre-specified at the systematic review protocol stage.

Subgroup analysis may be used to describe heterogeneity and assess any relationship between covariates (for example, ethnicity) and effect size (outcome). It is usually recommended that subgroup analysis should be relevant to the acupuncture research question and limited in number. However, the authors of two systematic reviews and meta-analyses conducted up to eight or more subgroup analyses.12*,9* Subgroup analyses have a high risk of findings being a consequence of chance.14 It is important to point out that meta-regression, unless there is a sufficiently large sample of studies (for example, two predictors would require 50 studies), has low power and can both produce unreliable positive results based on chance or false non-significant results. Only one systematic review contained a meta-regression on important clinical characteristics and methodological variables. A positive finding was cautioned,4 while the non-significant findings were not cautioned.

Statistical heterogeneity appears to be a common finding in the systematic reviews outlined in this document and random effect models are used. Hierarchical subgroup analysis has been proposed to be a better application to describe heterogeneity;16 meta-regression has been argued to have serious disadvantages.15

Reporting on acupuncture articles

The inclusion of graphical methods (funnel plots) in a systematic review can help the reader evaluate publication bias. Funnel plots were only evident in the publication in two4,10 of five systematic reviews.1,3,9*,11,12*

Statistical tests such as Begg’s and Egger’s may be used to identify publication bias,1 however, these tests can be unreliable with low study power.20 It is recommended that a discussion of the possible impact or not of publication bias, the reliability of assessment methods applied, along with any implications, should be outlined in systematic reviews, especially as part of the conclusion.

When a systematic review uses GRADE to appraise the quality of evidence, the meaning of this could be outlined explicitly in the discussion and the conclusion section. For example, Cheong et al3 concluded that they found no evidence of a significant effect for the primary outcomes yet did not state that ‘low quality’ means that they had limited confidence in this finding, and that true effect could be substantially different. The overview5 does not have adequate reporting, particularly around the finding of the clear effect of acupuncture on the outcome measurement (clinical pregnancy rate). It is important to improve the quality of reporting in systematic reviews and meta-analyses, as well as any future overviews.

Randomised controlled trials (RCTs)

There appears to be some confusion as to whether a trial is randomised or non-randomised in design. Cheong et al3 exclude Omodei (2010) and Feliciani (2011) for apparently being non-randomised, while Manheimer et al4 include these studies as randomised designs. When study eligibility has been predetermined to be a randomised controlled trial design, the inclusion of non-randomised trials is an error. For example, Qian et al’s12* inclusion of Magarelli et al (2009), a cohort study. Non-randomised designs may overestimate an effect.

Acupuncture method

In terms of intervention, some researchers impose questionable, ambiguous treatment restrictions, for example no moxibustion for patients with polycystic ovarian syndrome11 (which possibly limited data for analysis). In other cases, a systematic review may have a well-designed search strategy, but be poor in terms of the inclusion criteria for an acupuncture intervention. For example, the inclusion of randomised controlled trials to assess the impact of acupuncture on clinical pregnancy rate using acupuncture designed for pain relief around the time of egg collection.3 This is technically inappropriate. The acupuncture intervention should be well considered, and future randomised controlled trials should be designed to be appropriate in terms of an adequate amount of treatment, frequency and timing.

Control method for randomised controlled trials

The comparator group in efficacy trials should now be considered very carefully with a relevant, properly validated control. To date, controls to determine the efficacy of acupuncture in two- armed randomised controlled trials compare for example, acupuncture penetration by needling away from specific acupuncture points, ‘mild needling’ (pricking)21 or ‘pressure’ (apparently telescoping the skin).22 The Streitberger placebo needle was developed to explore the mechanism of pain and acupuncture 21 rather than for the subfertile population. Further, a limitation of the Park sham validation study was the likelihood of abnormal sensation in study participants due to a recent stroke anddisorientation.22

Sham acupuncture needling controls have been found to be physiologically active, with varied effect sizes relative to the type of sham. Therefore, the effect size of the sham control (if applied) should now be considered in future sample size calculations.23 Sham needling controls may underestimate the effect of acupuncture, leading to the unnecessary withdrawal of a potentially effective intervention that supports subfertile patients’ reproductive treatment. Cheong et al. (2013) advocated that randomised controlled trials should therefore consist of three study arms for comparative purposes.3 These arms could be (1) an adequate acupuncture intervention, (2) a validated control method, and (3) usual care. It is recommended that a pragmatic trial design24 with comparisons to usual care that include other therapies should be used to investigate the effectiveness of acupuncture on live birth rates.

Acupuncture sessions guide

A comprehensive acupuncture treatment management approach may be required prior to an IVF or ICSI cycle, for example lasting three to six months pre-treatment, to influence folliculogenesis.25 Acupuncture should be administered at the start of an assisted reproduction cycle, and frequently during the beginning of ovarian stimulation up to egg maturation. The aim should be to influence the response and development of ovarian follicles via improved blood flow, and embryo or blastocyst quality. Male factor subfertility could also be addressed. A recent RCT study is limited by the fact that one acupuncture session, adopted on day 6 to 8 of ovarian stimulation and before and after embryo transfer, did not reflect the recommendation of their consulted experts on the required amount and frequency of acupuncture to produce an intended result. The acupuncture intervention used in this study was below a minimal threshold.6 As with the same author’s 2006 trial,26 which followed a similar three- session treatment model, there was a tendency favouring acupuncture when compared to sham acupuncture for clinical pregnancy rate, but this did not reach statistical significance (Figure 1). Researchers should not undertreat subfertility patients by delivering a deficient number of treatments.

The British Acupuncture Council advocates that IVF or ICSI patients who wish to have acupuncture should receive an appropriate number of acupuncture treatments based on a thorough consultation and review.

Practitioners and their patients together could consider carefully the nature of the body of research outlined in this resource when devising a treatment plan. Currently, research indicates that acupuncture at the time of embryo transfer only should be a small part of an overall treatment strategy. Acupuncture can be provided post-transfer in the early luteal phase to possibly influence implantation, and during the two-week wait prior to a pregnancy test to help manage stress and anxiety resulting from uncertainty.

The evidence base for the exact number and frequency of acupuncture sessions on birth rate has not yet been robustly determined. Nevertheless, currently, research supports the findings that acupuncture at varied time points for an IVF or ICSI cycle, with increased frequency during ovarian stimulation as well as around the time of transfer, can have a statistically positive treatment effect on clinical pregnancy and live birth rate.
