Male factors account for roughly half of all causes of infertility with the main culprit being poor sperm quality, also known as idiopathic oligoasthenoteratozoospermia. Limited research has shown that acupuncture can significantly increase the motility of sperm, as well as sperm concentration without any experienced side effects. Over the past decade male sperm counts have significantly declined, and most of the current research points to two possibilities: lifestyle changes or endocrine-disrupting chemicals in the environment. Possible environmental factors include the presence of oestrogen and anti-androgens in water supplies as a result of common domestic and industrial products. Some lifestyle factors that can reduce sperm count include consuming too many soy products, the increase in the male’s age, diagnosis of diabetes or genitourinary infections, high levels of iodine, increases in scrotal temperature above 93.2 F, and obesity. Acupuncture treatment has been shown to aid in normal-formation of sperm, and increase sperm density.
