Among the reasons, smoking, adulterated food, hormonal disorder are featured. Our purpose is to check how micronutrients impact fertility. Brief description of the state of knowledge: Micronutrients deficiency, specifically zinc and selenium deficiencies have also unpropitious impact on fertility. In this review, the potential role of these microelements in male and female reproductive health is considered. Zinc had been proved to regulate sperm motility, spermatogenesis and reduce oxidative stress. Lower delivery of selenium decrease testosterone level by causing changes in receptor of the luteinising hormone. It is also compared with lower spermatozoa concentration. In this review the role of iron, manganese, lead, nickel, copper, magnesium and cobalt is described as well. Summary: Deficiencies of some micronutrients may make worse the fertility. That’s the reason why additional supplementation may be important in the treatment of infertility. Key words: fertility; micronutrients; microelements; zinc; selenium
