Nuts and Nutritional Factors in Management of Male Fertility: A Review

Infertility has a significant impact on the quality of lives of infertile couples, necessitating the exploration of approaches to reduce its prevalence and improve fertility chances. This review focuses on the role of tree nuts in male fertility, considering their potential effects on seminal fluid quality and sperm parameters. Nuts are rich in antioxidants such as vitamins C, D, and E, as well as minerals like zinc and selenium, which are known to have a positive influence on fertility. While numerous reviews have summarized the effects of various nutrients on male fertility, there is currently no published review specifically categorizing the effects of tree nuts on male fertility. This review aimed to fill that gap by summarizing the relevant literature on nuts and male infertility. The findings of reviewed studies suggest the beneficial effects of nut consumption on reproductive health and overall health. The improvement in lipid stability, oxidative stress, inflammation indicators, and endothelial function can potentially contribute to better reproductive health, particularly in relation to agedependent decreases in sperm quality and fertility.
