Acupuncture adjuvant to other active medications could affect hormonal levels such as LH, LH/FSH ratio, testosterone, and fasting insulin in women with polycystic ovarian syndrome.
Although limited by heterogeneity across studies, we found that acupuncture adjuvant to other active medications could affect hormonal levels such as LH, LH/FSH ratio, testosterone, and fasting insulin. Neuroendocrinological mechanisms of acupuncture have been extensively studied not only in pain research but also in reproductive medicine. Acupuncture is also known to modulate hypothalamic-pituitary-ovarian axis, which can affect menstruation cycles. Given that acupuncture stimulates pituitary beta-endorphin production, which has a tonic inhibitory effect on gonadotropin-releasing hormone pulse generator and pituitary LH secretion, it is possible that acupuncture may reduce ovulatory dysfunction and thus decrease the secretion of ovarian androgens in women with PCOS. Considering detected heterogeneity from our analysis, known variability in hormonal levels, the poor standardization of assays, and the specific PCOS phenotypic features, however, the currently available data from RCTs has yet to allow us to draw any firm conclusion whether acupuncture affects hormonal levels, thus recovering ovulatory function and menstruation cycle in women with PCOS.
