Nutrition and Infertility

Background: There is a growing body of evidence that nutri-tional habits may have an important role in fertility. The objec-tive of this study is to provide a comprehensive assessment of existing studies on the relationship between nutrition and in-fertility.Materials and Methods: Using an integrative review, articles for infertility and nutrition published from Jan1990 to Feb2019 in databases including MEDLINE, ISI Web of Knowledge, Scopus, Google Scholar, IranDoc, IranMedex, MagIran and SID in English and Persian languages were extracted. After as-sessment of inclusion and exclusion criteria, 41 articles were selected and reviewed.Results: Adequate intake of monounsaturated fatty acids, de-rived mainly from vegetable fats, as well as avoidance of un-saturated fatty acids may be effective in the prevention of infer-tility in females. Choice of plant rather than animal sources of proteins, decrease in glycemic load of the diet, use of dietary supplements containing iron and folic acid, could also be ben-eficial. Also a positive correlation is found between the con-sumption of too much carbohydrate and abnormal sperm motil-ity. Excessive consumption of sweet junk food and drinks and saturated fat are reported to cause the sperm count to decrease. There is a positive relationship between the intake of vitamin C and β-carotene and sperm count, concentration and the total progressive motile sperm count; between the intake of vitamin E, oral zinc supplement and progressive motile sperm count.Conclusion: According to the role of nutrition in infertility, it is suggested to integrate nutrition counseling into clinical guide-lines of infertility for individuals of reproductive age.
