Commentary on: Wu XK, Stener-Victorin E, Kuang HY, et al. Effect of acupuncture and clomiphene in Chinese women with polycystic ovary syndrome: a randomised clinical trial. JAMA 2017;317:2502–14.


Ovulatory dysfunction is considered to be one of the major characteristics of polycystic ovary syndrome (PCOS), which affects 5%–10% of women of reproductive age and leads to 70%–80% of anovulatory infertility. Many ovulation induction treatments, including clomiphene citrate, letrozole, exogenous gonadotropin and laparoscopic ovarian drilling, have limited effectiveness, safety and negative side effects. Acupuncture has been used in eastern Asian countries for thousands of years, and the use of acupuncture in reproductive endocrinology and infertility is becoming popular in research and clinical practice. Several clinical and animal experimental studies indicate that acupuncture may improve ovulation frequency by improving endocrine profile and normalising insulin sensitivity.1 2 However, evidence is of very low quality. Many studies have limitations, including failure to report important clinical outcomes, poor reporting of study methods, non-randomised controlled studies, small sample size and insufficient information on allocation concealment in randomised clinical trials; even the latest systematic review and meta-analysis still came to the conclusion that there is currently insufficient evidence to support the use of acupuncture for treatment of ovulation disorders in women with PCOS.3 4


This study carried out by Wu and colleagues assessed whether active acupuncture, either alone or combined with clomiphene, increases the likelihood of live births among women with PCOS. This was a randomised, multicentre, clinical trial undertaken in 27 hospitals. Double-blind (clomiphene vs placebo) and single-blind (active vs control acupuncture) factorial trials were conducted in PCOS. Live birth was the primary outcome, and adverse events were evaluated as the secondary outcomes.


Live births occurred in 29.4% of women treated with the active acupuncture plus clomiphene, 28.0% of women in the control acupuncture plus clomiphene group, 13.9% in the active acupuncture plus placebo group and 16.8% in the control acupuncture plus placebo group. There was no significant interaction between active acupuncture and clomiphene, although the live birth rate was significantly higher in the women treated with clomiphene than with placebo. Diarrhoea and bruising were more common in patients receiving active acupuncture than control acupuncture.5


These findings indicate that acupuncture, alone or with clomiphene, was not as effective as an infertility treatment in women with PCOS. In this research, circulating levels of progesterone, total testosterone, oestradiol and sex hormone-binding globulin were not significantly different between women receiving active versus control acupuncture. The results suggest that acupuncture may not improve serum indexes, although some animal experiment and clinical contrast studies suggest it may change the PCOS serum indexes, the inconsistency may be due to small simple size or confounding factors. Previous study suggested acupuncture can improve the insulin sensitivity. In this study, the author did not evaluate the changes in insulin sensitivity. The frequency of serious adverse events was very low and did not differ significantly among the groups. In the aspect of the adverse event, clomiphene was more frequently associated with back pain, while acupuncture may reduce the occurrence. Clomiphene is a first-line treatment drug in ovulation induction, and was used as positive control in this study. Many studies suggested that letrozole has the same and even better effect in ovulation induction for PCOS.6

Implications for practice

Whether acupuncture can play a synergistic role with letrozole requires further study because of different ovulation mechanisms, although clomiphene has no synergistic effect with acupuncture.

Although important clinical outcomes were explored in this study, many details still need an explanation, for example, the acupuncture points are different between active acupuncture and control groups with resultant deficiency in blinding, and the average dosage and frequency of clomiphene in ovulation induction have not been statistically analysed. In summary, this study by Wu et al prompts us to reconsider the role of acupuncture in the treatment of ovulation disorders in women with PCOS.
