Acupuncture is a simple painless medical procedure. Peer-reviewed research on Acupuncture and reproductive health conditions state four potential physiological mechanisms for its positive effects:

HORMONES - Acupuncture may mediate the release of neurotransmitters and stimulate the release of gonadatropin releasing hormone, thereby influencing menstrual cycles, ovulation and fertility.
BLOOD CIRCULATION - Acupuncture may stimulate blood flow to the Uterus, inhibiting uterine central sympathetic nerve activity.
STRESS - Acupuncture may stimulate the production of endogenous opioids, which may inhibit the central nervous system outflow, increase serotonin levels, and regulate the biological stress response.
INFLAMMATION - Acupuncture may mediate the immune systems response to the implanting embryo resulting in higher implantation rates and reduced early pregnancy loss.
