Effects of different acupuncture methods on polycystic ovarian syndrome: a systematic review and network meta-analysis.

Polycystic ovarian syndrome (PCOS) affects millions of women worldwide, causing hormonal imbalances, irregular periods, excess hair growth, weight challenges, and difficulty getting pregnant. Researchers wanted to know whether acupuncture could help — and which type of acupuncture works best for different PCOS symptoms.

A large scientific review published in BMC Complementary Medicine and Therapies analyzed 59 clinical trials involving nearly 6,000 women with PCOS. The researchers compared several acupuncture approaches, including traditional acupuncture, electroacupuncture (where a gentle electrical current is added to the needles), and acupoint catgut embedding (ACE), a technique where tiny absorbable threads are placed at acupuncture points for longer-lasting stimulation.

The results were encouraging across multiple areas. For women struggling with high testosterone levels and excess hair growth, both ACE and electroacupuncture showed meaningful improvements. For metabolic concerns like body weight and waist measurements — common challenges with PCOS — ACE ranked as the top-performing approach. Electroacupuncture showed promise for improving blood sugar and cholesterol levels. Perhaps most meaningfully for women trying to conceive, traditional acupuncture was associated with higher pregnancy rates compared to other options.

What this means for you is that acupuncture is not a one-size-fits-all treatment for PCOS. The best approach depends on which symptoms bother you most. If weight and hormonal balance are your primary concerns, ACE may be worth discussing with your provider. If excess hair growth or blood sugar are bigger issues, electroacupuncture might be a better fit. If you are trying to get pregnant, traditional acupuncture showed the most promise.

The researchers noted that more high-quality studies are still needed, so acupuncture should be considered a complement to — not a replacement for — your existing medical care. To explore these options safely, seek out a licensed acupuncturist with experience treating hormonal and reproductive health conditions.

This Bayesian network meta-analysis (NMA) evaluated 59 RCTs (n = 5,937) comparing acupuncture modalities — including manual acupuncture, electroacupuncture (EA), and acupoint catgut embedding (ACE) — against placebo or standard pharmacotherapy for PCOS across four clinical domains. Methodological quality was assessed using Cochrane RoB 2.0. For hyperandrogenism, ACE ranked highest for testosterone reduction (SUCRA = 81.7%), while EA demonstrated significant reduction in Ferriman-Gallwey scores versus placebo (MD: 1.52; 95% CrI [0.50, 2.53]; SUCRA = 84.9%). In metabolic parameters, ACE led for BMI (SUCRA = 90.9%) and waist-hip ratio (SUCRA = 95.3%). EA was preferred for LDL and fasting glucose reduction. For reproductive hormone outcomes, ACE ranked highest for LH and LH/FSH normalization. Manual acupuncture showed the highest SUCRA for pregnancy rate improvement (76.6%). Clinical takeaway: modality selection should be individualized based on the patient's primary complaint. Evidence quality limitations warrant cautious interpretation pending more rigorously designed trials.
