Abstract:

The diet of high-yield dairy cows process a very complex and acute problem. Much new knowledge in the area of production and preparation of feedstuffs, diet technology, and the interactions that occur between the components of the nutritive feed ration are required in order to resolve this problem. It is necessary constantly to coordinate feed norms with genetic potential which is ever changing and advanced. The observed problems must be resolved using multidisciplinary methods so that a diet can yield good health, and that health contribute to better reproduction and possibilities for more successful breeding and improved performance in cattle farming. In certain countries, thanks to their geographic position and climatic conditions which allow rainfall throughout the year, a natural green diet can be applied, which provides large numbers of green mass components, and with additives which can be supplemented relatively easily. This type of diet is not possible in our farms. It is very important to know which feedstuff components are laking for certain categories of cattle. The used ration must be constant and administered to animals of certain age or production characteristics in order to improve production results at cattle farms. A great problem occurs when diet is reduced due to dried grass and the resulting stress in animals. A 50% diet reduction in young cattle often results in the occurrence of respiratory diseases. Following 10-14 days of treatment, the disease disappears in young animals, but the energy deficit leads to the weakening (depression) of the immune system. Even a so-called high-energy diet often causes respiratory diseases. A diet deficient in proteins also affects cows after lactation, as opposed to a normative diet, and a reduced protein diet disturbs the microbial activity in the rumen and the synthesis of compounds which are important for both the cow and the calf, making room for the incidence of metabolic diseases, most often acidosis. This paper presents and integral description of cattle diet management according to phases, and a new approach to cattle diet with respect to fertility observed in reproduction over a longer time period at large diary cow farms.

Abstract:

Diet has an impact on male reproductive potential, but few studies have focused on the specific impact of food groups or dietary patterns on fertility. Male reproductive health, as indicated by improved semen parameters and increased chances of conceiving, is associated with the Mediterranean diet, while the Western diet is considered a risk factor for male infertility. The potential mechanisms that may explain the impact of these diets on semen quality are still largely unknown. However, numerous studies suggest that nutritional interventions are crucial for the preservation and improvement of male fertility. This review aims to summarize the most recent evidence on the influence of components of the Mediterranean diet on sperm parameters. Unlike other risk factors, dietary modulation represents a great opportunity for improving overall health and can also be an important tool in recommendations for male reproductive health.

Abstract:

Diet has a key role in the reproductive axis both in males and females. This review aims to analyze the impacts of different dietary patterns on fertility. It appears that the Mediterranean diet has a predominantly protective role against infertility, while the Western diet seems to be a risk factor for infertility. Moreover, we focus attention also on dietary patterns in different countries of the World (Middle Eastern diet, Asian diet). In particular, when analyzing single nutrients, a diet rich in saturated fatty acids, cholesterol, animal proteins, and carbohydrates with high glycemic index is highly associated with male and female infertility. Finally, we evaluate the effects of vegetarian, vegan, and ketogenic diets on fertility, which seem to be still unclear. We believe that comprehension of the molecular mechanisms involved in infertility will lead to more effective and targeted treatments for infertile couples.

Abstract:

Infertility affects 15% of the population in developed countries, and its prevalence is increasing. Fertility can be influenced by different factors. Although key factors like maternal age cannot be changed, there is growing evidence that other modifiable factors, such as diet, can have an impact on fertility. Diet has become increasingly important in recent years for a number of reasons: the new trend toward a healthy lifestyle, the higher prevalence of certain digestive disorders, a lack of time that leads people to consume more prepared and processed food, and personal choice to not eat meat, among others. To meet these needs, several diets have recently become popular, such as the Mediterranean diet, known as the gold standard of health; the DASH diet, known for preventing hypertension; the Western diet, characterized by processed food; the ketogenic diet, characterized by low carbohydrate intake; and the vegetarian diet, which is the choice for people who do not eat meat or animal by-products. Diets present a unique composition characterized by the presence or absence of specific nutrients, which have also been associated with male and female fertility individually. This review assesses the impact of these diets and of macro- and micronutrients on both female and male fertility.

Abstract:

Background: The relationship between diet and fertility continues to emerge, yet interventions underutilise this evidence within Australian primary health care (PHC). Infertility affects approximately 9% of the world’s population and 16% of Australian couples trying to conceive naturally. Current PHC practices do not address nor encourage improved diet for sperm and oocyte quality, ovulation and sperm production. Due to a lack of resources and training, general practitioners typically refer these individuals to fertility clinics for medical management. As a result, Australia ranks as the 6th highest global utiliser of assisted reproductive technology, with annual costs to treat infertility exceeding $46,000,000. Aim: To synthesise current evidence for the diet-fertility relationship and identify suitable PHC interventions for improving fertility related lifestyle risk factors. Method: A database search for published peer reviewed articles using MEDLINE, Scopus, Google Scholar, PubMed and Global Health was carried out, and narratively synthesised. Results: Poor diet, central adiposity and unhealthy weight are modifiable risk factors impacting fertility, and common amongst the Australian adult population. There are opportunities to address these risk factors by modifying existing lifestyle modification programs to improve the overall fertility profile of this demographic within PHC. Conclusion: It is possible to optimise fertility through lifestyle interventions that encompass dietary modification. Health and fertility treatment costs can potentially be improved if changes to diet and lifestyle are consistently addressed as first line management for infertility within PHC for appropriate individuals. Understanding evidence for interventions have importuning implications for policy and practice. Further work needs to describe how fertility lifestyle interventions can successfully translate into PHC practice.

Abstract:

Background: Increasing age is a strong risk factor for infertility, and there is accumulating evidence of the importance of a healthier diet for fertility. Whether a healthier diet modifies the association between increasing age and infertility has not been investigated. This study aimed to (i) examine if better diet quality could help reduce age-related infertility; and (ii) assess whether changes in diet quality over time are associated with fertility problems. Methods: Data were from Surveys 3 and 5 of the 1973–1978 birth cohort of the Australian Longitudinal Study on Women’s Health. Cross-sectional analysis with multivariable generalized linear models were used to examine the association between age and fertility status, adjusted for various confounders. Multiplicative and additive effect modification by diet quality was assessed, with additive effect modification evaluated with the relative risk for interaction (RERI). Results: In total, 3387 women were included from Survey 3 (age range 24–31 years) and 5614 women from Survey 5 (age range 30–38 years); 588 (17.4%) and 1321 (23.4%) self-reported to have fertility problems in the respective surveys. In Survey 3, compared to younger women with a good-quality diet, older women with a poor-quality diet had a 43% increased risk for fertility problems, with risk increasing after further adjustment for BMI (RR: 1.59; 95% CI: 1.07, 2.37) and PCOS (RR: 1.74; 95% CI: 1.15, 2.62). In Survey 5 in younger women (<33.9 years), there was no association between diet quality and risk for infertility problems. The RERI (across different adjusted models) was between −0.08 (−0.70, 0.55) to −0.39 (−1.40, 0.62) in survey 3 and 0.07 (−0.17, 0.31) to 0.08 (−0.17, 0.32) in Survey 5. Conclusions: There is little evidence to suggest effect modification on the effect of age and fertility problems with diet quality.

Abstract:

Male fertility has been declining globally over the past several decades, advancing from a personal issue to a public health problem. Beyond any doubt, a reduction in fertility (often characterized by low sperm count or motility) can severely threaten reproductive health and lifecourse framework in a long-term fashion. Aside from uncovering the currently unknown etiology of modern-day male infertility, the scientific and medical community faces a double burden: finding an efficient biomarker of impaired fertility and exploring any intervention that can act to enhance fertility. A plethora of nutritional compounds have been recognized as possible modulators of semen quality, and specific dietary patterns and nutrients appear to be accompanied by a lower risk of male infertility. Creatine, a conditionally essential nutrient, has caught attention as a male fertility-promoting candidate due to its role in sperm energy metabolism. This mini-review describes the creatine-related bioenergetics of spermatozoa, explores a connection between creatine levels and sperm quality in men, and critically examines available evidence for interventional studies with creatine to affect sperm viability.

Abstract:

Women with obesity have higher incidences of infertility, with longer time to conception and increased risk of pregnancy complications compared to women with normal body weight. There is a lack of evidence demonstrating the benefit of preconception maternal weight loss on fertility and pregnancy outcomes. We aimed to determine if preconception weight loss, either with diet modification or glucose-like peptide 1 receptor agonist liraglutide, improves maternal weight, fertility, and pregnancy outcomes. C57BL/6 female mice were fed either a high-fat diet (HFD) or chow for 8 weeks. HFD-fed dams were administered liraglutide (0.3 mg/kg, s.c., for 4 weeks) or switched to chow to induce weight loss. Prior to mating, liraglutide was ceased and mice continued on HFD. Mice in the ‘diet switch’ group continued on chow. Pregnancy rates were recorded. Maternal anthropometry and glucose tolerance were measured before and after the intervention and at late gestation. Offspring outcomes were assessed. Liraglutide or diet switch led to weight reduction, improved insulin resistance (P< 0.001), and enhanced fertility, particularly in the liraglutide group (P< 0.005). Liraglutide-treated mice had significantly higher gestational weight gain (GWG) compared to the diet switch group (P< 0.05), with similar weight and glucose tolerance in late gestation to HFD mice. In contrast, diet switch maintained similar weight and glucose tolerance in late gestation to control mice. Pre-pregnancy weight intervention with liraglutide was effective at restoring fertility. Diet modification also improved fertility and avoided catch up weight gain in pregnancy. Liraglutide may be a therapeutic strategy for weight loss to prepare for pregnancy. However, our study provides caution about the potential for excessive GWG without diet intervention in pregnancy.

Abstract:

There are conflicting results on the effect of diet on fertility. This study aimed to assess the effect of different dietary patterns on fertility outcomes in populations who conceive spontaneously and those requiring assisted reproductive technology (ART). A systematic search and meta-analysis were performed for studies investigating dietary patterns or whole diets in reproductive aged women requiring ART or conceived naturally. Outcomes were live births, pregnancy rates and infertility rates. In amount of 15,396 studies were screened with 11 eligible studies. Ten different diet patterns were grouped broadly into categories: Mediterranean, Healthy or Unhealthy. For the Mediterranean diet, on excluding high risk-of-bias studies (n = 3), higher adherence was associated with improved live birth/pregnancy rates in ART [OR 1.91 (95% CI 1.14–3.19, I2 43%)] (n = 2). Adherence to various Healthy diets was associated with improved ART outcomes (ProFertility diet and Dutch Dietary Guidelines) and natural conception outcomes (Fertility diet). However, due to the variability in Healthy diets’ components, results were not pooled. Studies demonstrated preliminary evidence for the role of dietary patterns or whole diets in improving pregnancy and live birth rates. However, due to heterogeneity across the literature it is currently unclear which diet patterns are associated with improvements in fertility and ART outcomes.

Abstract:

Most dairy cows suffer from negative energy balance in early lactation that can affect their fertility. Adding fat to the cattle diet increases the diet energy content. In this study, ketone bodies (acetone and acetoacetate), nonesterified fatty acids (NEFAs), and some individual fatty acids in serum and milk were used as biomarkers for negative energy balance and fertility in dairy cows supplemented with two sources of fat. A comparison of calcium salts of palm oil fatty acid versus MixPro-omega-3 (a heat-treated linseed oil) diet on the level of fatty acids in serum and milk of early lactating Holstein cows was assessed in relation to their fertility. The diets were formulated to be iso-nitrogenous and iso-caloric. Two diets were provided from day 0 to 30 days postpartum. Blood and milk samples were collected at 1st, 2nd, and 3rd weeks after calving. Results revealed that the increased serum and milk linoleic and linolenic acid with decreased saturated (palmitic and stearic acid) fatty acids and oleic acid are related to improved energy status with decreasing the ketone bodies and (NEFAs), and enhance the fertility of dairy cows received MixPro-omega-3 when compared with calcium soap fed group. The level of ketone bodies and NEFAs, increased in milk than in serum in the same group. The fertility was enhanced by giving MixPromega-3 diet compared with calcium soap diet.

Abstract:

Background: In the last years, several scientific societies and expert groups focused on the role played by nutritional factors, lifestyle and excess of body fat in interfering with female reproduction and fertility. In many studies a confounding factor is represented by polycystic ovary syndrome (PCOS) which is one of the major causes of infertility where genetic and family history are certainly playing a role, together with lifestyle and nutritional factors. Methods: In an attempt to define "the optimal fertility diet", we consider the role played by Mediterranean lifestyle and some macronutrients (animal and vegetable proteins) on ovulatory disorders and female fertility also considering some new visions derived from randomized trials of lifestyle programs in obese infertile women asking for in vitro fertilization or alternative assisted reproduction technologies. Results: Several reports are in favor of an increased consumption of either proteins or low-glycemic index carbohydrates to improve ovulatory disorders and female fertility. In studies concerning infertile women undergoing assisted reproduction, either structured exercise sessions and dietary intervention programs seem to be effective in improving menstrual cycles and fertility as demonstrated by the increased rate of natural conceptions. Conclusion: The findings of this review confirm the important impact of Mediterranean diet and lifestyle in preserving and improving fertility. However, epigenetic factors are very important in determining fertility rate, but genetic background and ethnicity are also playing crucial roles.

Abstract:

The effect of two classes of exogenous enzymes on the egg fertility traits, egg production efficiency and oviduct micro-structure of laying hens was evaluated. Forty-five laying hens (30-weeks old, 1.32-1.40 kg) were randomly allotted into three dietary treatments with fifteen birds per treatment (five birds each in three replicates per treatment) in a completely randomized design. Diet one served as the control diet. Diet two (FS diet) contained a nutrient-targeted exogenous enzyme preparation (Fullzyme®) at 200 g/ton, while diet three (DS diet) contained a mycotoxin-targeted exogenous enzyme preparation (Detoxizyme®) at 500 g/ton. Data on fertility traits (egg volume, length and breadth, weight, yolk diameter, albumen height, air cell, shell thickness, Haugh’s unit, and egg-lay), and egg production (feed intake, egg lay, egg lay efficiency, and feed cost per egg laid) were collected for 42 days. At the end of the experiment, three randomly selected birds per group were euthanized, and their oviducts were harvested and processed for histopathology. Hens fed enzyme supplemented diets had significantly (p < 0.05) better egg fertility traits. Feed intake in the control group did not vary (p > 0.05)from feed intake in the DS or FS group. However, feed cost per egg laid and egg-lay efficiency was higher in the control diet group than in the FS group or DS diet group. No pathologies were observed in the oviduct of birds fed enzymes supplemented or control diet. Exogenous enzymes in diet improved egg fertility traits and production without altering the oviduct micro-structure of Layer hens.

Abstract:

Infertility is a global health concern affecting 48 million couples and 186 million individuals worldwide. Infertility creates a significant economic and social burden for couples who wish to conceive and has been associated with suboptimal lifestyle factors, including poor diet and physical inactivity. Modifying preconception nutrition to better adhere with Food-Based Dietary Guidelines (FBDGs) is a non-invasive and potentially effective means for improving fertility outcomes. While several dietary patterns have been associated with fertility outcomes, the mechanistic links between diet and infertility remain unclear. A key mechanism outlined in the literature relates to the adverse effects of inflammation on fertility, potentially contributing to irregular menstrual cyclicity, implantation failure, and other negative reproductive sequelae. Therefore, dietary interventions which act to reduce inflammation may improve fertility outcomes. This review consistently shows that adherence to anti-inflammatory diets such as the Mediterranean diet (specifically, increased intake of monounsaturated and n-3 polyunsaturated fatty acids, flavonoids, and reduced intake of red and processed meat) improves fertility, assisted reproductive technology (ART) success, and sperm quality in men. Therefore, integration of anti-inflammatory dietary patterns as low-risk adjunctive fertility treatments may improve fertility partially or fully and reduce the need for prolonged or intensive pharmacological or surgical interventions.

Abstract:

In this article we develop and apply a method for estimating fertility in paleodemographic study. The proportion D30+/D5+, generated from standard life table calculations, is used to estimate relative fertility rates for eight Woodland and Mississippian populations represented by skeletal series from west-central Illinois. The inferred pattern of fertility increase through time is then considered in the context of key variables that define diet, technology, and sedentism. We conclude that changes in diet or food preparation techniques are implicated in this demographic change. The absence of a significant increment in juvenile mortality in association with the elevated fertility rates suggests that these changes in fertility explain the regional population increase previously inferred from mortuary and habitation site densities.

Abstract:

Reproductive health is progressively declining due to multiples endogenous and exogenous factors, such as environmental contaminants, diet and behavior. Accumulated evidences confirm that fertility and reproductive function have been adversely affected by exposure to chemical contaminants released in the environment. Today, the impact of diet and behavior on reproductive processes is also receiving special attention from the scientific community. Indeed, a close relationship between diet and fertility has been proven. Furthermore, a combination of unhealthy behavior, such as exposure to hazardous compounds and stress factors, poses living organisms at higher risk of reprotoxic effects. In particular, it has been described that poor life behaviors are associated with reduced male and female fertility due to decreased gamete quality and function. Most of the erroneous behaviors are, furthermore, a source of oxidative stress that, leading to epigenetic alterations, results in an impaired reproductive fitness. This review reports the detrimental impact of the most common environmental chemical stressors, diet, and behavior on reproductive functionality and success. Although clear evidences are still scarce, reassuring data are provided that a healthy diet and reverting unhealthy lifestyles may be of help to recover physiological reproductive conditions.

Abstract:

Excessive weight seems to negatively influence fertility, and as it is a modifiable factor, understanding this relationship can contribute to infertility treatment. Adipose tissue is responsible for releasing several hormones and cytokines related to the reproductive system, such as leptin, TNF-a, and Interleukin-6, substances that can negatively impact female fertility. Additionally, a woman's diet and lifestyle can influence body weight and fertility. Food consumption, characterized by a high intake of foods with high energy density, high levels of sugar, saturated fat, and poor nutrients, as well as physical inactivity, can favor excessive weight. Thus, losing body weight obtained through a healthy diet associated with physical activity may restore fertility in overweight women.

Abstract:

Obesity and overweight are common conditions that have consequences not only on general health but also to a great extent on reproductive health. There is a high prevalence of obese women in the infertile population and numerous studies have highlighted the link between obesity and infertility. Obesity contributes to anovulation and menstrual irregularities, reduced conception rate and a reduced response to fertility treatment. It also increases miscarriage and contributes to maternal and perinatal complication. Reduction of obesity, particularly abdominal obesity, is associated with improvements in reproductive functions; hence, treatment of obesity itself should be the initial aim in obese infertile women before embarking on ovulation-induction drugs or assisted reproductive techniques. While various strategies for weight reduction, including diet, exercise, pharmacological and surgical intervention exist, lifestyle modification continues to be of paramount importance.

Adults which developed from larvae that fed on a pinto bean diet containing diflubenzuron (Dimilin) or an ecdysone agonist (RH 5992) were inbred and outcrossed with adults which developed from larvae that were fed on a normal pinto bean diet. Data were collected on fecundity, fertility, and sperm transfer. Sublethal doses of both compounds administered to H. zea larvae caused reduced fertility in surviving male imagos but had no effect on fecundity or fertility of the female imagos. Reduced fertility in treated males was largely caused by a lower incidence of sperm transfer. Implications of our results for H. zea population management are discussed.

Abstract:

Pro-healthy behaviours, including the diet, are significant factors in maintaining women’s fertility health. However, to improve the patient’s nutrition management, it is important to seek food-derived bioactive compounds to support fertility treatment. This review analysed recent studies of food compounds related to fertility, using databases including PubMed, Web of Science and Science Direct as well as PRISMA (preferred reporting items for systematic reviews) to ensure complete and transparent reporting of systematic reviews. This review lists foods associated with a higher birth rate, using original papers from the last five years (2015). The analysis included the impact of food compounds such as caffeine, fatty acids, folates and vitamin D, as well as the intake of fish, whole grains, dairy and soya. In addition, dietary patterns and total diet composition supporting women’s fertility were also analysed. The results will encourage further research on the relationship between food components and fertility.

Abstract:

In brief Fertility has decreased due to advanced maternal age and the rising prevalence of the metabolic syndrome. Using quantitative image analysis methods, we show that these factors are associated with delayed preimplantation embryo development in a mouse model. Abstract Delayed maternal age, obesity and diabetes are associated with reduced fertility. We investigated how age and obesity/metabolic syndrome impact fertility and hypothesized that its decrease is due to defects in preimplantation embryo development. Three groups of female C57Bl6 mice (12 weeks, 9 months and 1 year old) were fed either a high-fat diet for 8 weeks, to induce obesity and the metabolic syndrome, or a control chow diet. Body weight and composition, glucose tolerance and insulin resistance were assessed. Fecundity was evaluated by mating and pregnancy rates, as well as by the number of embryos. Embryo quality was assessed morphologically, and cell fate composition was analysed in preimplantation embryos by state-of-the-art single-cell quantitative confocal image analysis. The high-fat diet was associated with increased adiposity, glucose intolerance and insulin resistance, especially in the older mice. Fecundity was affected by age more than by the diet. Both age and high-fat diet were associated with reduced cell fate allocation, indicating a delay in the preimplantation embryo development, and with increased expression of GATA3, an inhibitor of placentation. These results support that age and the metabolic syndrome reduce fertility through mechanisms which are present at conception or very early in pregnancy.

Full text

Abstract:

Phytoestrogens are plant-derived compounds with oestrogenic activity. They are common in both human and animal diets, particularly through soy-based foods. This study assessed whether exposure of adult male rats to a high phytoestrogen diet for 3–25 days affected their fertility, and assessed possible mechanisms through which phytoestrogens may disrupt fertility. Adult males, fed a high phytoestrogen diet for 3 days, demonstrated significantly reduced fecundity. This effect was transient, with fecundity returning to control levels by day 12. The expression of oestrogen receptor-α and androgen receptor mRNA was increased in the initial segment of the epididymis, but decreased in the cauda epididymis following 3 days on the high phytoestrogen diet. Epididymal sperm counts cannot account for the reduction in fertility at day 3. However, lipid peroxidation of epididymal sperm was significantly increased in animals fed a high phytoestrogen diet for 3 days. Disruption of the steroid regulation of the epididymis by phytoestrogens may alter its function, resulting in decreased quality of sperm, and thereby reducing fecundity.

Abstract:

Efforts to reduce greenhouse gas (GHG) emissions from cattle production have led to modifications of livestock diet composition aimed at reducing CH4 emissions from enteric fermentation. These diet modifications can result in varied manure types that may differentially affect GHG emissions when applied to soil. The purpose of this experiment was to examine the effect of different manure types on GHG emissions. We conducted an incubation experiment, comparing the manure from livestock fed a corn-based diet (CM) to that from livestock fed a traditional barley-based diet (BM). The manures were applied to three soil types (with varied soil fertility and pH) and compared to a control (without manure application). Carbon dioxide (CO2) emissions were greater from CM than from BM across all soil types (29.1 and 14.7 mg CO2-C kg−1, respectively). However, CM resulted in lower N2O emissions relative to BM in the low fertility soil (4.21 and 72.67 μg N2O-N kg−1, respectively) and in lower CH4 emissions relative to BM in the two acidic soils (0.5 and 2.5 μg CH4-C kg−1, respectively). Total GHG emissions (sum of CO2, N2O, and CH4) were similar between CM and BM across all soil types, but CM (unlike BM) had 52–66% lower emissions in the low fertility soil relative to both CM and BM in the high fertility soil. Our study shows that manure and soil type interact to affect GHG emissions and that CM may mitigate N2O emissions relative to BM when applied to low fertility soils.

Abstract:

Background Approximately one-third of Japanese couples currently worry or previously worried about infertility. To develop strategies for the primary prevention of infertility as a population approach, it is important for the general population to be knowledgeable about fertility and infertility. The internet may contribute to the dissemination of information regarding infertility and fertility. However, few studies have examined online information about fertility. Objective This study aimed to quantitatively examine online Japanese-language information about lifestyle factors associated with reduced fertility. Methods We conducted online searches, using the 10 search terms with the highest numbers of searches that people hoping to conceive are likely to input in two major search engines in Japan (Google Japan and Yahoo! Japan). From the 2200 retrieved websites, 1181 duplicates and 500 websites unrelated to our objective were excluded, resulting in a final dataset of 519 websites. Coding guidelines were developed for the following lifestyle factors associated with reduced fertility: sexually transmitted diseases, psychological stress, cigarette smoking, alcohol use, nutrition and diet, physical activity and exercise, underweight, overweight and obesity, and environmental pollutants. Results In terms of the website author’s professional expertise, 69.6 % of the coding instances for the selected lifestyle factors were mentioned by hospitals, clinics, or the media, whereas only 1.7% were mentioned by laypersons. Psychological stress (20.1%) and sexually transmitted diseases (18.8%) were the most frequently mentioned lifestyle factors associated with reduced fertility. In contrast, cigarette smoking, alcohol use, nutrition and diet, physical activity and exercise, underweight, overweight and obesity, and environmental pollutants were mentioned relatively infrequently. The association between reduced fertility and sexually transmitted diseases was mentioned significantly more frequently by hospitals and clinics than by the media (P<.001). The association between reduced fertility and nutrition and diet was mentioned significantly more frequently by the media than by hospitals and clinics (P=.008). With regard to the sex of the target audience for the information, female-specific references to psychological stress, sexually transmitted diseases, nutrition and diet, underweight, physical activity and exercise, and overweight and obesity were significantly more frequent than were male-specific references to these lifestyle factors (psychological stress: P=.002, sexually transmitted diseases: P<.001, nutrition and diet: P<.001, underweight: P<.001, physical activity and exercise: P<.001, overweight and obesity: P<.001). Conclusions Of the lifestyle factors known to be related to reduced fertility, cigarette smoking, alcohol use, and male-specific lifestyle factors are mentioned relatively infrequently in online information sources in Japan, and these factors should be discussed more in information published on websites.

Abstract:

ABSTRACT Aims This work was designed to assess the role of diet and dietary habits on women fertility. Materials and methods This study was carried out in seven different centers and hospitals in Baghdad in the period between January and September 2014. Participants were 400 adult women selected conveniently; their age ranged from 17 to 47 years and they were divided into two groups. Group I included 300 fertile women and group II included 100 infertile women. A specific questionnaire had been designed and used for data collection Results It was found that there was a significant difference in weight and body mass index (BMI) between the infertile group and control group. The mean of weights was 73.07 vs 69.06 kg for infertile and the control group respectively, while the mean BMI was 28.83 vs 26.70 for the infertile group and the control group respectively. Moreover, the infertile women consumed more of carbonated beverages, tea, chicken, and fish than the control group, while they consumed less milk and red meat than the control group. Also, the infertile group consumed less corn oil and olive oil than the control group (5 and 0% vs 21 and 2%) respectively, while they used to consume more solid fat and combined fat than the control group (2 and 6% vs 0 and 2.7%) respectively. Conclusion Although treatment options for infertility are available, their high cost and frequency of adverse events have motivated the identification of dietary factors related to infertility. The current study identified diet as one of the modifiable risk factors that potentially impacts fertility in the selected groups; hence, it is important to focus more on the role of diet in women fertility and increase the awareness of women to it, along with suggesting more educational programs at the primary health care level.

Abstract:

Infertility is a disease globally affecting 20–30% of the reproductive age female population. However, in up to 50% on recorded cases, problems with infertility are ascribed to men; therefore, it is important to popularize healthy eating also in this group. During the last decade, it has been observed that society’s lifestyle changed drastically: reduced energy expenditure in physical activity per day, increased consumption of hypercaloric and high-glycemic-index foods with high content of trans fats, and reduced consumption of dietary fiber, which negatively affects fertility. Increasing evidence points to a link between diet and fertility. It is becoming clear that well-planned nutrition can also contribute to the effectiveness of ART. The low-GI plant-based diet appears to have a positive effect, especially when it is based on Mediterranean dietary patterns: rich in antioxidants, vegetable protein, fiber, MUFA fatty acids, omega-3, vitamins, and minerals. Importantly, this diet has been shown to protect against chronic diseases associated with oxidative stress, which also translates into pregnancy success. As lifestyle and nutrition seem to be important factors affecting fertility, it is worth expanding knowledge in this regard among couples trying to conceive a child.

Abstract:

Phytoestrogens are plant-derived compounds that are particularly abundant in soy-based foods. Exposure to exogenous oestrogenic chemicals has been implicated in declining male fertility. The aim of this study is to deduce whether adult phytoestrogen exposure affects the reproductive function of male rats, and by what mechanisms phytoestrogens may be acting. Six male rats were transferred from a low soy diet (control) to an experimental high soy diet, while nine males remained on the control diet. On days 3, 6 and 12 all males were mated and litter sizes recorded. A second group of male rats kept on the same dietary regimen were killed after 3, 6 or 12 days on the diets. The epididymides were collected from the rats. Real-time PCR was performed to measure mRNA quantities of oestrogen receptors alpha (ERα) and beta (ERβ), and androgen receptor (AR). The TBARS assay for lipid peroxidation was performed on epididymal sperm samples from rats fed the high or low phytoestrogen diet for 3 days. The average litter size following 3 days on the high soy diet was significantly lower than that for rats maintained on the control diet. Litter sizes returned to control levels by day 12. ERα and AR expression decreased in the cauda region of the epididymis following 3 days on the high soy diet, but returned to control levels by day 6. Lipid peroxidation of epididymal sperm was increased in rats fed the high phytoestrogen diet for 3 days. Short-term exposure to high phytoestrogen levels transiently reduces male fertility, and alters hormone receptor expression. Endocrine disruption may impair fertility by reducing antioxidant protection of sperm stored in the epididymis.

Abstract:

An experiment was conducted to study the effect of dietary vit E and Se on egg production, fertility and hatchability of native ducks in intensive system of management. Basal diet mixed with 0.5g vitamin E and 50 ppm selenium per 100 kg feed constitutes the feed of treatment group against only basal diet to control group that continued for 12 weeks of experiment period. Eggs produced were incubated for production of ducklings. Egg production, fertility and hatchability were recorded. Blood serum samples were estimated for total protein, total cholesterol and GOT at eighth week. The study revealed significant improvement of egg production, fertility and hatchability for the treatment group. Biochemical parameters of blood showed no significant difference between treatment and control. Thus it may be concluded that dietary supplementation of vitamin E and selenium to the laying native ducks is beneficial for egg production, fertility and hatchability.

Abstract:

The aim of the present study was to evaluate the toxicological influence of different concentrations of tobacco smoke and low-protein diet on fertility, reproduction, and survival of offspring of Wistar female rats. We studied three generations, two litters in each. There were 192 animals in parent generation. Animals were exposed to three different concentrations of tobacco smoke that were reflected by the carbon monoxide (CO) concentration (500, 1000, and 1500 mg CO/m3 air) during 11 weeks (six before and two weeks during mating, and three weeks of pregnancy). Additionally, animals were divided into two subgroups that were fed normal or low-protein diet. In the present study, we concentrated on the indices describing the reproduction ability, fertility, and rearing of pups of mothers exposed to tobacco smoke. The parameters of newborns survival were estimated also. We concluded that neither tobacco smoke exposure nor the low-protein diet changed the duration of pregnancy. The tobacco smoke in all doses and low-protein diet had a negative influence on fertility, reproduction, and survival of newborns from exposed mothers. This influence was mainly attributed to the tobacco smoke exposure. The levels of carboxyhaemoglobin were increasing with increasing tobacco smoke concentration.

Abstract:

Background: Adherence to healthy diets favouring seafood, poultry, whole grains, fruits and vegetables, are related to better fertility in women and better semen quality in men. Along with pharmaceutical treatment, the role of a proper diet and lifestyle has been highlighted in many diseases like hypertension and diabetes. Likewise, the role of diet in fertility is a less explored area which holds great potential. The first step towards implementation of this fact will be increasing the awareness about the same among healthcare professionals, mainly doctors. Methods: A cross-sectional study including medical practitioners in 3 hospitals each in Tamil Nadu and Kerala. Assuming 50% prevalence and 8% allowable error, sample size was calculated to be 156. Data collection was done using a semi-structured and self-administered questionnaire. Results: Among the total, 80.1% of the medical practitioners responded that diet played an important role in boosting fertility of an individual and 72.1% had faced questions regarding the foods to improve fertility. In terms of knowledge, 28% of the respondents were able to score more than 60 out of a maximum score of 100. Conclusions: Future efforts should concentrate on solidifying emerging evidence and to jointly consider female and male diets along with other interventions for infertility management.

Abstract Approx. 60–80 million couples globally are affected by the problem of infertility. The issue is important both for the couple trying to conceive and for the whole society in which the couple lives. Lifestyle, including nutrition, may have both a positive and a negative impact on the outcomes of infertility treatment. The aim of this paper is to assess the relationship between knowledge in the area of fertility diet and its actual use, and types of fertility disorders among women undergoing treatment in a fertility clinic. A group of women was analyzed statistically, divided into 3 groups according to their couple’s cause of infertility – the causes of infertility were described as: the male factor, the female factor, and the idiopathic factor. The study group answered questions that comprised a fertility diet knowledge test; the frequency of consumption of particular food products in a individual groups was also analyzed. Correspondence analysis showed differences between the groups in the number of points scored in the fertility diet knowledge test, as well as in the consumption of sweets, crisps and sticks, and nuts and seeds. Women among whom the main cause of infertility was defined as the male factor scored the highest numbers of points in the fertility diet knowledge test, women with the idiopathic cause of infertility scored slightly lower numbers of points, while women whose main cause of infertility was defined as the female factor scored the lowest numbers of points. Women from couples with idiopathic infertility consumed sweets, crisps and sticks the most often, followed by women with the cause of infertility identified on their side, with the lowest frequency of consumption of sweets identified among women whose partner was infertile. Nuts and seeds were consumed the most frequently by women whose partners were infertile, followed by women with the cause of infertility identified on their side, while women with the idiopathic cause of infertility consumed nuts and seeds the least frequently. These examples show that correspondence analysis is well suited to the assessment of the influence of lifestyle on fertility; in addition, it makes it possible to recognize certain correlations that may not be observed in standard statistical tests.

Abstract:

Organismal fitness is partly determined by how well the nutritional intake matches sex-specific metabolic requirements. Metabolism itself is underpinned by complex genomic interactions involving products from both nuclear and mitochondrial genomes. Products from these two genomes must coordinate how nutrients are extracted, used and recycled, processes vital for fuelling reproduction. Given the complicated nature of metabolism, it is not well understood how the functioning of these two genomes is modulated by nutrients. Here we use nutritional geometry techniques on Drosophila lines that only differ in their mtDNA, with the aim to understand if there is nutrient-dependent mitochondrial genetic variance for male reproduction. We first find genetic variance for diet consumption, indicating that flies are consuming different amounts of food to meet new physiological requirements. We then find an interaction between mtDNA and diet for fitness, suggesting that the mtDNA plays a role in modulating diet-dependent fitness. Our results enhance our basic understanding of nutritional health and our chimeric genomes.

Abstract:

Fertility is the main element affecting hatchability as an important indicator in breeder flocks’ performance. Roosters’ aging reduces their fertility. Using additives such as selenium helps to delay this reduction through antioxidant properties of Se. Replacing inorganic Se by the nano form in poultry diet improves fertility. The aim of this study was to assess effects of different amount of nano-Se on SelP, GPx4 and SelW gene expression in broiler breeder rooster’s testis. A total of 30 fifty-weeks-old broiler breeder males were randomly divided into five groups including a control group (fed basal diet) and four treatments containing basal diet plus 0.3 mg/kg sodium selenite (1), 0.15 mg/kg nano-Se (2) 0.3 mg/kg nano-Se (3) and 0.6 mg/kg nano-Se (4). The results indicated that mRNA expression levels of SelP, GPx4 and SelW genes increased significantly (p<0.05) after dietary supplementation of nano-Se compared to control and sodium selenite groups. In conclusion, dietary supplementation of nano-Se was more effective than sodium selenite on mRNA expression level of tested genes.
