Nutrition plays a pivotal role in female infertility

Background: Infertility is a common problem affecting 10–15% of couples. Female infertility is caused by one or more of factors including polycystic ovary syndrome (PCOS), premature ovarian insufficiency, hyperprolactinemia, damage to fallopian tubes, endometriosis and cervical causes. Nutrition plays a key role in determining reproductive health and can positively or negatively influence fertility. This review focuses on modifiable diet and nutrition in women infertility.Methods: An internet based search through PubMed, Google Scholar, and the American Society of Reproductive Medicine and the European Society of Human Reproduction and Embryology, with the search terms including: infertility of women , PCOS , endometriosis , dietary pattern , food intake and nutrient that was restricted to the publications in the recent 25 years (since 1991-2016).Result: Date showed that intake of trans-unsaturated fats is associated with a higher risk of endometriosis and infertility (P-value= 0.001). Further intake of long-chain omega-3 fatty acids is associated with a lower risk of infertility (P-value= 0.03). Glycemic index plays an important role in the diet in infertile women, actually high glycemic index foods have strong association with a greater risk of infertility (P-value=0.005). Unexpectedly, an inverse association exists between high-fat dairy food intake and risk of infertility.Conclusion: This study suggests that there is some link between diet and risk of infertility in women. These findings suggest that high monounsaturated fatty acid intake, the consumption of vegetables rather than meat as a protein source; low glycemic carbohydrates and whole-fat dairy products may influence the rate of fertility.
