For centuries, acupuncture has been used to treat some causes of infertility. Acupuncture is based on a Chinese belief in the balance of energy flow through the body. If this flow hits a blockage or imbalance, your health is negatively affected. Acupuncture needles, long and thin needles that vary in length based on insertion point, stimulate points to restore energy flow. Acupuncture is most effective for couples experiencing a functional problem like irregular ovulation, and is used as a complementary form of therapy with other treatments.
