The connection ranging from diet plan, time balance and you may fertility in boys

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.

Inclusion

New frequency of sterility certainly one of partners of reproductive age brackets, based on certain provide, away from 8% to twenty five% [1–3]. Male sterility is the merely cause for infertility inside the 20–30% regarding cases and you will something causing sterility during the fifty% of all of the infertility times . The new investigations out of male fertility constantly includes scientific test and you will comparison with the source thinking of one’s pursuing the sperm details: frequency, complete sperm fertility, quantity, motility and you may morphology (Table 1) . Reasonable sperm count and you will/otherwise top quality is available inside ninety% off people which have virility problems . On the comparison from fertility, the fresh new levels of male reproductive hormones are analyzed. Now, the fresh new unit constitution off cum muscle, examined by comparing the amount of DNA fragmentation otherwise oxidative fret could have been much more taken into account. Several studies use the DNA fragmentation list (DFI) as the a sign of pregnancy achievement. Based on Evenson and you may Wixon, DFI range of less than six% for the compliment men, when you’re a great DFI out-of ? 30% is actually of this less fertility . Already outlined hereditary activities, as well as both chromosomal aberrations and you will monogenic changes, account for just about ten–15% out of instances of men infertility . The cause having fertility issues may also be ecological facts. The goal of the research was to become familiar with the relationship between diet, time equilibrium and you can fertility rates into the guys.

Approach from literature browse

A comprehensive literature search of published studies in various languages, was carried out in electronic databases, including: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Review and Google Scholar. 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’, Reno NV chicas escort ‘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.
