Acupuncture or phy(F)itoestrogens vs. (E)strogen plus progestin on menopausal symptoms. A randomized study.

Menopause can bring uncomfortable symptoms like hot flushes, night sweats, and mood changes that affect daily life. Many women wonder whether there are effective alternatives to hormone therapy (HT), which some prefer to avoid. A clinical study published in Gynecological Endocrinology set out to answer exactly that question by comparing acupuncture, soy isoflavones (a type of plant-based estrogen), and traditional hormone therapy in 75 postmenopausal women experiencing hot flushes.

Over three months, women were randomly assigned to one of three treatments: a low-dose estrogen and progestin pill, weekly acupuncture sessions, or twice-daily soy isoflavone supplements. Researchers measured changes in menopausal symptom scores and quality of life before, during, and three months after treatment ended.

All three approaches reduced menopausal symptoms during the treatment period. Acupuncture performed comparably to hormone therapy on overall symptom scores and quality of life measures. For hot flush relief specifically, about 42% of women receiving acupuncture experienced an 80% or greater reduction in vasomotor symptoms — nearly identical to the 44% seen with hormone therapy. Soy isoflavones also helped, though somewhat less effectively for hot flushes.

Perhaps most encouraging was what happened after treatment stopped. Three months later, women who had received acupuncture maintained their quality-of-life improvements significantly better than those who had taken hormones, suggesting acupuncture's benefits may have a lasting carry-over effect.

For women who cannot or prefer not to use hormone therapy — whether due to personal preference, medical history, or concerns about side effects — this study offers reassuring evidence that acupuncture is a credible, effective option for managing menopausal symptoms.

If you are considering acupuncture for menopause relief, seek out a licensed, board-certified acupuncturist with experience treating women's health conditions.

This three-arm randomized trial (n=75 postmenopausal women with hot flushes) compared weekly acupuncture, soy isoflavones (75 mg twice daily), and conjugated estrogens/medroxyprogesterone acetate (0.30 mg/1.5 mg/day) over 12 weeks, with a 3-month post-treatment follow-up. Primary outcomes were Greene's Climacteric Scale and Menopause Quality of Life (MenQoL) scores. Greene's total score declined significantly in all groups: HT (−5.6±3.1), acupuncture (−6.9±4.5), and phytoestrogens (−3.4±4.3; p<0.05 vs. HT). Vasomotor sub-score reduction ≥80% was achieved by 41.7% of acupuncture patients versus 44% with HT (NS) and 17.4% with phytoestrogens (p<0.05 vs. HT). MenQoL improved similarly across all groups during treatment; however, at 3-month post-treatment follow-up, acupuncture demonstrated superior MenQoL maintenance compared to HT (p<0.006). Clinical takeaway: Acupuncture is a clinically viable, non-hormonal intervention for climacteric symptoms, with comparable efficacy to low-dose HT and superior durability of quality-of-life benefit post-cessation.
