Infertility is defined as not being able to get pregnant in a year despite the regular unprotected sexual intercourse. Infertility is an important health problem affecting the entire world. Adequate and balanced nutrition plays an important role in the prevention and treatment of infertility. Energy balance, body mass index and macro nutrients have obvious effects on infertility. The purpose of this review is to explain the effects of micronutrients on infertility in light of the foregoing scientific data. Micronutrients with antioxidant properties are (such as vitamin A, vitamin C, vitamin E, zinc and selenium) thought to be effective in infertility by preventing DNA damage and destroying free radicals. Folate, vitamin D and vitamin B12 have been shown to be effective in the prevention and treatment of infertility due to the effects of genitourinary system. Further studies are needed to clarify the relationship between micronutrients and infertility and to evaluate the use of doses and health benefits of supplements.
