Iron and a Man ’s Reproductive Health: the Good, the Bad, and the Ugly

AbstractPurpose of ReviewTo discuss the physiologic and pathologic effects of iron on men ’s reproductive health.Recent FindingsIron overload diseases are associated with hypogonadotropic hypogonadism, infertility, and sexual dysfunction in men. Recent findings have elucidated the roles by which iron may affect the male reproductive axis.SummaryIron is requisite for life. Iron can also catalyze the production of reactive oxygen species. To maintain balance, the human body tightly regulates dietary iron absorption. Severe iron overload disorders —e.g., hereditary hemochromatosis and β-thalassemia—occur when these regulatory mechanisms are deficient. While iron is necessary, the male reproductive system is particularly sensitive to iron overload. Hypogonadotropic hypogonadism, infertility, and sexual dysfunction commonly occur if excess iron from iron overload disorders is not removed. The average male in the USA consumes significantly more iron than needed to replace daily losses. How this degree of iron loading may affect one’s reproductive health remains less clear, but there is evidence it may have adverse effects.
