The connection ranging from diet, time equilibrium and virility from inside the males

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.

Introduction

The fresh new frequency of sterility certainly one of people away from reproductive age ranges, considering various offer, out-of 8% in order to 25% [1–3]. Men sterility is the merely factor in sterility inside 20–30% of times and you can a very important factor leading to infertility for the fifty% of all the sterility instances . Brand new investigations from male potency constantly boasts medical examination and you can comparison towards site opinions of your own following the semen variables: volume, overall sperm count, concentration, motility and you may morphology (Desk 1) . Low sperm count and you can/or top quality exists from inside the ninety% away from partners that have fertility issues . On the analysis from virility, the newest density of men reproductive hormones also are assessed. Now, this new molecular structure regarding jizz tissue, analyzed by the evaluating the amount of DNA fragmentation or oxidative fret could have been increasingly taken into consideration. Multiple education use the DNA fragmentation list (DFI) due to the fact a sign of pregnancy victory. Centered on Evenson and you can Wixon, DFI range regarding 3 to 5% when you look at the compliment males, if you are a great DFI off ? 30% is on the shorter virility . Currently defined hereditary circumstances, also both chromosomal aberrations and you may monogenic changes, make up no more than ten–15% of cases of men sterility . The cause having fertility trouble can also be environment activities. The goal of the study was to become familiar with the relationship anywhere between diet, opportunity balance and you will virility costs during the boys.

Means from books research

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 League City escort 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.

Progressive motility 32% (31–34)
Full (modern + nonprogressive) motility 40% (38–42)
