Positioning nutrigenomics and nutrigenetics within the framework of male infertility exploration

Male infertility, a complex result of genetic, environmental, and lifestyle factors, has gained significant focus in contemporary medical research. The intricate interplay between genetics, nutrition, and male fertility is crucial for understanding the complex mechanisms that underlie male reproductive health. The twenty-first century has seen a paradigm shift in medicine, where holistic personalized medical care is posited to be ideal and effective. In this regard, this narrative review explored how the convergence of dietary habits and genetic predispositions influence male fertility in the context of predictive, preventive, and personalized medicine. This review explored the evolving landscape of genetic insights into male infertility, creating awareness of their possible engagement as genetic predictors for idiopathic male infertility. It also dissects the roles of nutrigenomics and nutrigenetics in shaping preventive male reproductive medicine strategies through distinguishing the influence of dietary components on genetic expression and further elucidating how epigenetic alterations, influenced by dietary components, impact male fertility, potentially imparting transgenerational effects. Furthermore, this review offers potential personalized reproductive remedies in the form of functional and super foods, gut microbiome enhancers, redox homeostasis and proposes personalized nutrition as an intervention with high prospects in the context of improving male fertility.
