The relationship anywhere between diet plan, times balance and you will virility into the people

Abstract. Research conducted in recent years provides more and more evidence that diet can have a significant impact on male fertility. The aim of the study was to analyze the relationship between diet, energy balance and fertility in men. A comprehensive literature search of published studies in various languages, was carried out in electronic databases. The direct analysis included 96 works published between 2008 and 2018, including 12 randomized controlled trials and 23 systematic reviews and meta-analyses. A strong adherence to a healthy dietary pattern is positively correlated with total sperm count, progressive motility and total motile sperm count (all p < 0.05). However, attention is drawn to the fact that foods that are considered “healthy” can sometimes contain a significant amount of pollution, which negatively affect the semen parameters. An adequate intake of antioxidants or their supplementation have been quite effective in the prevention and treatment of male infertility. The improvement of pregnancy rate after antioxidant therapy ranged in various studies from 11% to 41%. An important problem, however, may be choosing the right dose of the supplement or finding an appropriate combination of antioxidants that may be more effective than any single antioxidant. The normalization of men’s body weight is beneficial for the quality of sperm and the concentration of male reproductive hormones. Further, long-term studies require the assessment of the impact of drastic weight loss after bariatric surgery on male fertility.

Addition

Brand new incidence off infertility certainly one of people regarding reproductive age ranges, centered on individuals sources, away from 8% so you’re able to twenty five% [1–3]. Men sterility is the just cause for sterility from inside the 20–30% from instances and you can the one thing leading to infertility within the fifty% of all the sterility circumstances . The latest evaluation away from male potency always boasts medical test and you can evaluation towards the source philosophy of after the semen parameters: frequency, full sperm fertility, concentration, motility and morphology (Dining table 1) . Reduced sperm fertility and you may/otherwise top quality can be acquired during the 90% out-of people having virility trouble . On the comparison off fertility, the brand new levels of male reproductive hormone are also analyzed. Now, the latest unit structure regarding sperm tissues, escort in Hampton reviewed from the researching the degree of DNA fragmentation otherwise oxidative be concerned could have been much more considered. Numerous knowledge utilize the DNA fragmentation list (DFI) once the an indicator of being pregnant success. According to Evenson and Wixon, DFI ranges out-of 3 to 5% inside suit guys, whenever you are a DFI out-of ? 30% is actually regarding the reduced virility . Currently outlined genetic items, as well as each other chromosomal aberrations and you can monogenic changes, take into account no more than ten–15% off cases of male infertility . The cause to have virility trouble can certainly be ecological things. The purpose of the research was to get to know the connection ranging from diet, time equilibrium and you can fertility rates inside the guys.

Randomized controlled trials, observational and qualitative studies published between 2008 and 2018 (up to and including March) were included. The following keywords related to male infertility, diet, nutrients and their combinations (made by applying operators AND and OR) were used in the search: ‘male infertility’, ‘sperm quality’, ‘idiopathic oligozoospermia’, ‘astenoazospermia’, ‘oligoastenoteratozoospermia’, ‘sperm DNA damage’, ‘nutritional status’, ‘BMI’, ‘obesity’, ‘diet’, ‘nutrition’, dietary pattern’, ‘food’, ‘nutrient’, ‘fatty acids’, ‘antioxidant’, ‘supplementation’, ‘vitamin C’, ‘vitamin E’,’ vitamin A’, ‘folate’, ‘zinc’, ‘selenium’, ‘L-carnitine’, ‘glutathione’, ‘coenzyme Q₁₀‘, ‘N-acetylcysteine’, ‘lycopene’. Reference lists of studies extracted from the primary electronic search were used to identify additional relevant studies.
