Key Finding
Auricular therapy as an adjunct treatment for PCOS demonstrated significant improvements in BMI, hormonal parameters, and psychological health measures, though insufficient evidence supports its use as a standalone intervention.
Researchers analyzed 18 studies involving 1,231 women with polycystic ovary syndrome (PCOS) to determine whether auricular therapy—a form of ear acupuncture—could help manage this hormonal condition. PCOS affects many women of reproductive age and can cause irregular periods, excess hair growth, weight gain, and fertility problems.
The review found that auricular therapy alone did not show sufficient benefits for PCOS. However, when used alongside other treatments, it showed promise. Women who received ear acupuncture combined with traditional Chinese herbal medicine experienced reductions in body mass index (BMI) and improvements in anxiety and depression scores. When combined with metformin (a common PCOS medication), the therapy helped reduce BMI, waist-hip ratio, and luteinizing hormone levels—a hormone often elevated in PCOS. When paired with body acupuncture, it improved BMI, hormone ratios, and insulin resistance markers.
No serious side effects were reported in any of the studies, though the authors noted that adverse events may be underreported. The psychological benefits are particularly noteworthy, as many women with PCOS experience anxiety and depression related to their symptoms.
It's important to understand that these findings suggest auricular therapy works best as a complementary treatment rather than a standalone solution. The studies analyzed had some limitations, including small sample sizes and varying quality. More rigorous research is needed to fully establish the therapy's effectiveness. If you're considering auricular therapy for PCOS, work with a qualified, licensed acupuncturist experienced in treating reproductive and metabolic conditions.
This systematic review and meta-analysis of 18 RCTs (n=1,231) evaluated auricular therapy (AT) efficacy for PCOS management. Auricular therapy as monotherapy showed insufficient evidence for PCOS treatment. However, as adjunctive therapy, AT demonstrated significant benefits: combined with TCM formulas, it reduced BMI (MD: -0.82, 95% CI: -1.60 to -0.03), SAS scores (MD: -3.81), and SDS scores (MD: -4.22). Combined with metformin, reductions occurred in BMI (MD: -0.77), WHR (MD: -0.03), and LH levels (MD: -0.81). Combined with acupuncture, improvements included BMI (MD: -3.21), LH levels (MD: -0.80), LH/FSH ratio (MD: -1.39), and HOMA-IR (MD: -0.10). No serious adverse events were reported, though underreporting remains possible. Clinical takeaway: Auricular therapy shows promise as complementary treatment for PCOS, particularly for anthropometric, hormonal, and psychological parameters, though high heterogeneity, bias risk, and small sample sizes necessitate cautious interpretation pending higher-quality trials.
