Acupuncture or auricular electro-acupuncture as adjuncts to lifestyle interventions for weight management in PCOS: protocol for a randomised controlled feasibility study.

Polycystic ovary syndrome (PCOS) affects many women and can make weight management especially challenging. Carrying extra weight can worsen PCOS symptoms, including irregular periods, hormonal imbalances, and insulin resistance — making weight loss both important and frustratingly difficult for those living with the condition.

A research team in Australia designed a study to explore whether acupuncture or a specialised technique called auricular electro-acupuncture (AEA) could help women with PCOS lose weight when combined with lifestyle coaching. AEA involves applying gentle electrical stimulation to specific points on the outer ear, and researchers believe it may help regulate the nervous system in ways that address some of the root causes of PCOS, including insulin resistance.

The trial enrolled 39 women aged 18–45 with a PCOS diagnosis and a BMI between 25 and 40. Participants were randomly placed into one of three groups: body electro-acupuncture plus lifestyle coaching, AEA plus lifestyle coaching, or lifestyle coaching alone. The lifestyle support came from a telephone-based health coaching service. The 12-week programme measured not just weight and body measurements, but also blood sugar, hormone levels, menstrual regularity, heart rate variability, mood, and quality of life.

Importantly, this was a feasibility study — meaning its primary goal was to find out whether this type of trial is practical and acceptable to participants, rather than to prove that acupuncture definitively causes weight loss. The researchers were examining recruitment rates, how well participants stuck to the programme, and whether the methods felt safe and credible to those involved.

The findings from this study could pave the way for larger, more definitive research into acupuncture as a support tool for women managing PCOS and weight. If you are curious about whether acupuncture may be right for your PCOS journey, speak with a qualified and registered acupuncture practitioner who has experience in women's health.

This prospective, three-arm, open-label parallel RCT evaluated the feasibility and acceptability of body electro-acupuncture (BEA) and auricular electro-acupuncture (AEA) as adjuncts to a telephone-based lifestyle intervention (Get Healthy Service) for weight management in women with PCOS. Thirty-nine participants aged 18–45, with Rotterdam criteria-confirmed PCOS and BMI 25–40 kg/m², were randomised across 12 weeks. Primary outcomes focused on trial feasibility: recruitment and retention rates, adherence, credibility, and safety. Secondary outcomes were comprehensive, encompassing anthropometrics, OGTT-derived insulin sensitivity (AUC trapezoid), androgens, menstrual cyclicity, Ferriman-Gallwey scores, HRV, blood pressure, and validated psychological measures. The AEA arm was specifically selected for its proposed modulation of sympathetic tone — a mechanism relevant to the hyperinsulinaemia and autonomic dysregulation characteristic of PCOS. No efficacy data are reported in this protocol paper. Clinical takeaway: this is a well-designed feasibility framework that, if recruitment and retention targets are met, could support a fully powered RCT examining electro-acupuncture as an integrative intervention in metabolic and reproductive PCOS management.
