TLDR
It is advisable to have a varied and balanced diet based on vegetables and fruit, fish and seafood, nuts, seeds, whole-grain products, poultry, and low-fat dairy products, and the incorporation of carnitine supplements and coenzyme Q10 in therapeutic interventions seems promising.Abstract:
In up to 50% of cases, infertility issues stem solely from the male. According to some data, the quality of human semen has deteriorated by 50%–60% over the last 40 years. A high-fat diet and obesity, resulting from an unhealthy lifestyle, affects the structure of spermatozoa, but also the development of offspring and their health in later stages of life. In obese individuals, disorders on the hypothalamic-pituitary-gonadal axis are observed, as well as elevated oestrogen levels with a simultaneous decrease in testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) levels. Healthy dietary models clearly correlate with better sperm quality and a smaller risk of abnormalities in parameters such as sperm count, sperm concentration and motility, and lower sperm DNA fragmentation. Apart from mineral components such as zinc and selenium, the role of omega-3 fatty acids and antioxidant vitamins should be emphasized, since their action will be primarily based on the minimization of oxidative stress and the inflammation process. Additionally, the incorporation of carnitine supplements and coenzyme Q10 in therapeutic interventions also seems promising. Therefore, it is advisable to have a varied and balanced diet based on vegetables and fruit, fish and seafood, nuts, seeds, whole-grain products, poultry, and low-fat dairy products.read more

Microplastics: A Threat for Male Fertility
TL;DR: In this paper, the main changes in sperm quality along the lifespan and the upcoming studies on the effects of microplastics in male fertility in mammals are summarized and discussed. But the effect of MP exposure on male reproduction and sperm quality is poorly known.

Impact of Polyphenolic-Food on Longevity: An Elixir of Life. An Overview.
TL;DR: In this paper, the effects of these phytochemicals (either pure forms or polyphenolic-food) are reviewed and summarized according to affected cellular signaling pathways, and the effectiveness of the anti-aging preventive action of nutritional interventions based on diets rich in poly-phenolic food, such as the diets of the Blue zones, are discussed.

TL;DR: A growing body of evidence points to a link between diet and female fertility as mentioned in this paper, and it is worth investigating whether the composition of the gut microbiota correlates with the frequency of infertility.

NEW DEBATE International estimates of infertility prevalence and treatment-seeking: potential need and demand for infertility medical care
TL;DR: The current evidence indicates a 9% prevalence of infertility (of 12 months) with 56% of couples seeking medical care, lower than those typically cited and remarkably similar between more and less developed countries.

TL;DR: Saturated fats are not associated with all cause mortality, CVD, CHD, ischemic stroke, or type 2 diabetes, but the evidence is heterogeneous with methodological limitations, and Dietary guidelines must carefully consider the health effects of recommendations for alternative macronutrients to replace trans fats and saturated fats.
