How Acupuncture Affects Hormones
Acupuncture influences the endocrine system through the hypothalamic-pituitary-ovarian (HPO) axis — the hormonal command chain that governs reproductive function. By regulating this axis, acupuncture can normalize the production and cycling of estrogen, progesterone, LH, and FSH. It also directly affects insulin sensitivity, which is central to many hormonal conditions including PCOS.
PCOS: Polycystic Ovary Syndrome
PCOS affects an estimated 10% of women of reproductive age and is the leading cause of female infertility. It's characterized by elevated androgens, irregular or absent ovulation, and insulin resistance. A landmark Swedish study found that regular electroacupuncture reduced testosterone levels, regulated menstrual cycles, and improved ovulation frequency in women with PCOS.
Irregular Cycles
Whether your cycle is too long, too short, unpredictable, or absent, acupuncture works to restore regularity by addressing the underlying pattern. Treatment is timed to your cycle phases — different points and approaches are used depending on where you are in your cycle — to progressively normalize the rhythm.
PMS and Painful Periods
Premenstrual syndrome — bloating, mood swings, breast tenderness, irritability, cramping — is understood in Chinese medicine as Liver Qi stagnation, often combined with Blood deficiency or Cold in the uterus. Most patients notice significant improvement in PMS symptoms within 2–3 cycles of treatment.
Perimenopause and Menopause
Hot flashes, night sweats, sleep disruption, mood changes, and brain fog respond well to acupuncture. Research consistently shows acupuncture reduces hot flash frequency and severity. In Chinese medicine, these symptoms reflect a deficiency of Kidney Yin — the cooling, nourishing aspect of the body.
