Abstract and Figures

There is a growing body of evidence that nutritional habits may have a significant effect on both male and female fertility. Maintenance of normal body mass may be effective in the prevention of infertility resulting from ovulatory disorders. Underweight and, to a larger degree, overweight and/or obesity, are related to the enhanced risk of infertility. Insulin resistance is an important pathogenic mechanism that may impair ovulation. Adequate intake of monounsaturated fatty acids, derived mainly from vegetable fats, as well as avoidance of trans isomers of unsaturated fatty acids which are present in industrially produced cakes and sweets, crisps, fast-foods, powdered soups and hard margarines, may be effective in the prevention of infertility in females. Choice of plant rather than animal sources of proteins, decrease in glycemic load of the diet, use of dietary supplements containing iron and folic acid, could also be beneficial. Avoidance of vitamin B12 deficiency and its supplementation seem to be important in the prevention of early miscarriages. Sufficient intake of antioxidants also promotes female reproductive functions. Free radical processes play an important role in the development of male factor infertility. It was shown that proper intake or supplementation with antioxidants may be effective in its prevention and treatment. Such nutrients as zinc, selenium and folic acid act beneficially on sperm quality. A well-balanced diet seems to play an important role in the prevention of infertility in both sexes.

Introduction: in recent decades, there has been an increase in the prevalence of infertility in the population. Numerous studies confirm that the nutritional status plays a key role in fertility. Objective: analyze the nutritional factors that may influence the fertility in men and women. Material and methods: a review was performed on the nutritional factors that may influence male and female fertility. Results: there are several factors associated with infertility such as advanced age, the presence of structural alterations in the reproductive system and diseases, environmental pollution and lifestyle. In relation to the diet, it is emphasized that the high intake of saturated fats, trans fatty acids, proteins of animal origin, could have a detrimental effect on fertility, whilst the intake of complex carbohydrates, fibre, monounsaturated fats and omega-3 fatty acids could have a benefit effect. Also, it is essential provide an adequate intake of folic acid, B12, vitamin A, D, C y E, calcium, iron, zinc, selenium and iodine to prevent impairments in fertility. Conclusion: the prevention and treatment of fertility impairment in women and men should consider the nutritional approach given its importance in the reproduction.

Background Abnormal body mass and related metabolic disorders may affect female reproductive health. The purpose of the study was to determine the prevalence of underweight, overweight, obesity, lipid and glucose metabolism disorders, hypertension, and metabolic syndrome, among Polish women of childbearing age. Methods One thousand five hundred eighty-eight non-pregnant Polish women of childbearing age (20–49 years) who participated in the Multi-Centre National Population Health Examination Survey (WOBASZ II study) in 2013–2014, were assigned to 3 age groups: 20–29 years (n = 403), 30–39 years (n = 600) and 40–49 years (n = 585). Measurements of weight, height, waist circumference, blood pressure, blood lipids, and blood glucose were taken. For statistical analysis, the Kruskal-Wallis, Chi-Square, and Cohran-Armitage tests were used. Results Of the participants, 4.3% were determined to be underweight, 25.2% were overweight, 15% were obese, and 53.1% had abdominal obesity. With age, the prevalence of both excessive body mass and abdominal obesity tended to increase, and that of underweight to decrease. Frequency of hypercholesterolemia and hypertriglyceridemia found in the whole group were 50% and 12.6% respectively, and also tended to rise with age. Low serum HDL-cholesterol (high density lipoprotein cholesterol) levels were found in 15.1% of the participants. Prevalence of impaired fasting glucose in the whole group was 8.2% and tended to increase with age. Diabetes was found in 1.2% of the participants and its prevalence also tended to rise with age, at the borderline of significance. Frequency of arterial hypertension and metabolic syndrome in the whole group was 15.7% and 14.1% respectively and both tended to increase with age. Conclusions Overweight and obesity, especially of abdominal type, and the related metabolic abnormalities are common in Polish women of childbearing age. Their prevalence tends to increase with age. Underweight is relatively common in the youngest age group.

Cognitive capacity can be influenced by components of the diet. Low glycemic index foods seem to improve attention, memory and functional capacity, while those rich in simple sugars are associated with difficulty in concentration and attention. The brain needs a continuous supply of amino acids for the synthesis of neurotransmitters, especially serotonin and catecholamines. Low levels of serotonin have been linked to decreased learning, reasoning and memory. The quality and type of dietary fat can also affect intellectual and mental capacity. High saturated fat intake has been related to cognitive deterioration while the consumption of polyunsaturated fatty acids (docosahexaenoic acid) has beneficial effects in their prevention. It is advisable to consume diets with an adequate ratio (5:1) of omega-6: 3 fatty acids (Mediterranean diet) given that they are associated with better memory capacity and lower risk of cognitive deterioration. Vitamins B1, B6, B12, B9 (folic acid) and D, choline, iron and iodine exert neuroprotective effects and improve intellectual performance. In parallel, antioxidants (vitamins C, E, A, zinc, selenium, lutein and zeaxanthin) have a very important role in the defense against oxidative stress associated with mental deterioration and in the improvement of cognition. Currently, there is a high consumption of diets rich in saturated fats and refined sugars and low intake of fruits, vegetables and water that can negatively affect cognitive ability. Adequate nutrition is necessary to optimize brain function and prevent cognitive decline.

Malnutrition is a major problem in developing countries, and obesity and eating disorders are increasingly common in developing as well as developed countries. The reproductive axis is closely linked to nutritional status, especially undernutrition in the female, and inhibitory pathways involving detectors in the hind brain suppress ovulation in subjects with weight loss. Recovery may occur after minimal reacquisition of weight because energy balance is more important than body fat mass. Anorexia nervosa and bulimia nervosa affect up to 5% of women of reproductive age causing amenorrhoea, infertility and, in those who do conceive, an increased likelihood of miscarriage. Obesity can affect reproduction through fat cell metabolism, steroids and secretion of proteins such as leptin and adiponectin and through changes induced at the level of important homeostatic factors such as pancreatic secretion of insulin, androgen synthesis by the ovary and sex hormone-binding globulin (SHBG) production by the liver. WHO estimates that 9 to 25% of women in developed countries are severely obese, and obese mothers are much more likely to have obese children, especially if they have gestational diabetes. Obesity-associated anovulation may lead to infertility and to a higher risk of miscarriage. Management of anovulation with obesity involves diet and exercise as well as standard approaches to ovulation induction. Many obese women conceive without assistance, but pregnancies in obese women have increased rates of pregnancy-associated hypertension, gestational diabetes, large babies, Cesarean section and perinatal mortality and morbidity. Among contraceptors, the fear of weight gain affects uptake and continuation of hormonal contraceptives, although existing trials indicate that any such effects are small. For all methods of hormonal contraception, weight above 70 kg is associated with increased failure rates.

Polycystic ovary syndrome (PCOS) is a common endocrine condition in women of reproductive age associated with infertility and menstrual dysfunction and an increase in risk factors for cardiovascular disease and diabetes mellitus. Although weight loss has been shown to improve metabolic and reproductive fitness in this group (1), the effect of varying diet composition has not been researched. Recently there has been increased community interest in a high protein/low carbohydrate diet. This may aid in increased weight loss (2) due to the increased satiating power of protein and may improve insulin sensitivity through maintenance of lean body mass with weight loss (3). This randomised controlled trial examined the differential effects of replacing dietary protein with carbohydrate in weight loss on reproductive and metabolic physiology. Overweight women (mean BMI 37.7 ± 6.5 m2) were randomised to either a low protein (LP) (n = 14) (30% fat, 55% carbohydrate, 15% protein) or a high protein (HP) (n = 14) (30% fat, 40% carbohydrate, 30% protein) diet. The diet consisted of 12 weeks energy restriction (~ 6000 kJ) followed by 4 weeks weight maintenance with a weekly exercise and support group throughout. Improvements in menstrual cyclicity (ovulation and menstrual cycle lengths), insulin homeostasis and lipid profile and decreases in weight (7.5%) and abdominal fat (12.5%) occurred independent of diet composition. 3 pregnancies additionally resulted (2 HP, 1 LP). Improvements in menstrual cyclicity were associated with greater decreases in insulin resistance, as measured by the homeostasis model, and fasting insulin (P = 0.011). On the LP diet, high-density lipoprotein cholesterol (HDL-C) decreased 10% in energy restriction (P = 0.008) and free androgen index (FAI) increased 44 % in weight maintenance (P = 0.027). There were no changes in HDL-C in energy restriction or FAI in weight maintenance for the HP diet. Each group was provided with a representative HP or LP test meal for that intervention and post-prandial insulin and glucose analysed as the area under the curve (AUC). Test meal AUC glucose was higher for the LP compared to the HP diet at weeks 0 and 16 (Figure 1).

Infertility is an important medical and social problem that has an impact on well-being. A significant development in the last 10 years in the study of human infertility has been the discovery that oxidative sperm DNA damage has a critical role in the etiology of poor semen quality and male infertility. Selenium (Se) is an essential element for normal testicular development, spermatogenesis, and spermatozoa motility and function. The predominant biochemical action of Se in both humans and animals is to serve as an antioxidant via the Se-dependent enzyme glutathione peroxidase and thus protect cellular membranes and organelles from peroxidative damage. We explored the efficacy of Se in combination with vitamin E for improving semen parameters and pregnancy rates in infertile men. The study included 690 infertile men with idiopathic asthenoteratospermia who received supplemental daily Se (200 μg) in combination with vitamin E (400 units) for at least 100 days. The mean age of cases was 28.5 years (range 20-45), and the median age was 30 years. These cases had presented with male factor infertility (primary or secondary) for at least 1 year. The longest and shortest duration of infertility was 10 years and 1 year, respectively. The median time of diagnosis of infertility was 1 year with a mean of 2.5 years. We observed 52.6% (362 cases) total improvement in sperm motility, morphology, or both, and 10.8% (75 cases) spontaneous pregnancy in comparison with no treatment (95% confidence interval: 3.08 to 5.52). No response to treatment occurred in 253 cases (36.6%) after 14 weeks of combination therapy. Mean difference between semen analyses of cases before and after treatment was 4.3% with a standard deviation of 4.29. On the basis of paired t-test results, combination therapy with oral Se and vitamin E was effective for treatment of asthenospermia or asthenoteratospermia or induction of spontaneous pregnancy (P ≤ 0.001). Supplemental Se and vitamin E may improve semen quality and have beneficial and protective effects, especially on sperm motility. We advocate their use for the treatment of idiopathic male infertility diagnosed with asthenoteratospermia or asthenospermia in semen analysis.

Palmitoleic acid (cis-16:1n-7), which is produced by endogenous fat synthesis, has been linked to both beneficial and deleterious metabolic effects, potentially confounded by diverse determinants and tissue sources of endogenous production. Trans-palmitoleate (trans-16:1n-7) represents a distinctly exogenous source of 16:1n-7, unconfounded by endogenous synthesis or its determinants, that may be uniquely informative. To investigate whether circulating trans-palmitoleate is independently related to lower metabolic risk and incident type 2 diabetes. Prospective cohort study from 1992 to 2006. Four U.S. communities. 3736 adults in the Cardiovascular Health Study. Anthropometric characteristics and levels of plasma phospholipid fatty acids, blood lipids, inflammatory markers, and glucose-insulin measured at baseline in 1992 and dietary habits measured 3 years earlier. Multivariate-adjusted models were used to investigate how demographic, clinical, and lifestyle factors independently related to plasma phospholipid trans-palmitoleate; how trans-palmitoleate related to major metabolic risk factors; and how trans-palmitoleate related to new-onset diabetes (304 incident cases). Findings were validated for metabolic risk factors in an independent cohort of 327 women. In multivariate analyses, whole-fat dairy consumption was most strongly associated with higher trans-palmitoleate levels. Higher trans-palmitoleate levels were associated with slightly lower adiposity and, independently, with higher high-density lipoprotein cholesterol levels (1.9% across quintiles; P = 0.040), lower triglyceride levels (-19.0%; P < 0.001), a lower total cholesterol-HDL cholesterol ratio (-4.7%; P < 0.001), lower C-reactive protein levels (-13.8%; P = 0.05), and lower insulin resistance (-16.7%, P < 0.001). Trans-palmitoleate was also associated with a substantially lower incidence of diabetes, with multivariate hazard ratios of 0.41 (95% CI, 0.27 to 0.64) and 0.38 (CI, 0.24 to 0.62) in quintiles 4 and 5 versus quintile 1 (P for trend < 0.001). Findings were independent of estimated dairy consumption or other fatty acid dairy biomarkers. Protective associations with metabolic risk factors were confirmed in the validation cohort. Results could be affected by measurement error or residual confounding. Circulating trans-palmitoleate is associated with lower insulin resistance, presence of atherogenic dyslipidemia, and incident diabetes. Our findings may explain previously observed metabolic benefits of dairy consumption and support the need for detailed further experimental and clinical investigation.

Endometriosis is a prevalent but enigmatic gynecologic disorder for which few modifiable risk factors have been identified. Fish oil consumption has been associated with symptom improvement in studies of women with primary dysmenorrhea and with decreased endometriosis risk in autotransplantation animal studies. To investigate the relation between dietary fat intake and the risk of endometriosis, we analyzed 12 years of prospective data from the Nurses' Health Study II that began in 1989. Dietary fat was assessed via food frequency questionnaire in 1991, 1995 and 1999. We used Cox proportional hazards models adjusted for total energy intake, parity, race and body mass index at age 18, and assessed cumulatively averaged fat intake across the three diet questionnaires. During the 586 153 person-years of follow-up, 1199 cases of laparoscopically confirmed endometriosis were reported. Although total fat consumption was not associated with endometriosis risk, those women in the highest fifth of long-chain omega-3 fatty acid consumption were 22% less likely to be diagnosed with endometriosis compared with those with the lowest fifth of intake [95% confidence interval (CI) = 0.62-0.99; P-value, test for linear trend (Pt) = 0.03]. In addition, those in the highest quintile of trans-unsaturated fat intake were 48% more likely to be diagnosed with endometriosis (95% CI = 1.17-1.88; Pt = 0.001). These data suggest that specific types of dietary fat are associated with the incidence of laparoscopically confirmed endometriosis, and that these relations may indicate modifiable risk. This evidence additionally provides another disease association that supports efforts to remove trans fat from hydrogenated oils from the food supply.

To investigate associations between preconception dietary patterns and IVF/intracytoplasmic sperm injection (ICSI) outcomes validated by biomarkers of the homocysteine pathway. Observational prospective study. A tertiary referral fertility clinic at the Erasmus University Medical Centre, Rotterdam, The Netherlands. One hundred sixty-one couples undergoing IVF/ICSI treatment. No interventions other than the Dutch governmental recommendation of folic acid. Dietary patterns, blood and follicular fluid concentrations of folate, vitamin B12, vitamin B6, homocysteine, and fertilization rate, embryo quality, and pregnancy. In women, two dietary patterns were identified. The "health conscious-low processed" dietary pattern (variation explained 12.1%) was characterized by high intakes of fruits, vegetables, fish, and whole grains and low intakes of snacks, meats, and mayonnaise, and positively correlated with red blood cell folate (β=0.07). The "Mediterranean" dietary pattern (variation explained 9.1%), that is, high intakes of vegetable oils, vegetables, fish, and legumes and low intakes of snacks, was positively correlated with red blood cell folate (β=0.13), and vitamin B6 in blood (β=0.09) and follicular fluid (β=0.18). High adherence by the couple to the "Mediterranean" diet increased the probability of pregnancy, odds ratio 1.4 (95% confidence interval 1.0-1.9). A preconception "Mediterranean" diet by couples undergoing IVF/ICSI treatment contributes to the success of achieving pregnancy.

OBJECTIVE: To determine the impact of nutritional supplementation on optimization of reproductive health in women. STUDY DESIGN: A double-blind, placebo-controlled pilot study was initiated to determine the effects of FertilityBlend(TM) (Daily Wellness Co., Sunnyvale, California), a proprietary nutritional supplement containing chasteberry and green tea extracts, L-arginine, vitamins (including folate) and minerals. Changes in progesterone level, basal body temperature, menstrual cycle, pregnancy rate and side effects were monitored. RESULTS: Thirty women aged 24-46 years who had tried unsuccessfully to conceive for 6-36 months completed the study. After 3 months, the supplement group (n = 15) demonstrated a trend toward an increase in mean midluteal phase progesterone level (from 8.2 to 12.8 ng/mL, P = .08) and a significant increase in the average number of days in the cycle with basal temperatures >37degreesC during the luteal phase (6.8-9.7 days, P = .04). The placebo group (n = 15) did not show any notable changes after treatment in any of the parameters studied. After 5 months, 5 of the 15 women in the supplement group were pregnant (33%), and none of the 15 women in the placebo group were (P<.01). No significant side effects were noted. CONCLUSION: Nutritional supplementation may provide an attractive alternative or complement to conventional fertility therapy.

To review the role of oxidative stress in the context of female fertility. Oxidative stress is associated with decreased female fertility in animal and in-vitro models, but no studies to date have directly assessed the relationship in women. Exposures associated with oxidative stress and with evidence to influence the timing and maintenance of a viable pregnancy include pregnancy complications (e.g. preeclampsia), extremes of body weight, alcohol, tobacco, and caffeine intake. Intake of antioxidant nutrients, including use of multivitamins, impacts the generation of reactive oxygen species and may play a beneficial role in female fertility. Infertility is a significant public health problem and diagnosis and treatment are stressful, invasive, and costly. The role of oxidative stress in female fertility is an understudied and compelling area for investigation. Identifying modifiable factors to decrease oxidative stress in the gynecologic environment may be an inexpensive and noninvasive therapy for increasing fertility.

Many studies have examined whether caffeine, alcohol, or specific beverages containing these substances affect fertility in women. However, most of these studies have retrospectively collected information on alcohol and caffeine intake, making the results susceptible to biases. We followed 18,555 married women without a history of infertility for 8 years as they attempted to become (or became) pregnant. Diet was measured twice during this period and prospectively related to the incidence of ovulatory disorder infertility. There were 438 incident report of ovulatory disorder infertility during follow-up. Intakes of alcohol and caffeine were unrelated to the risk of ovulatory disorder infertility. Comparing the highest to lowest categories of intake, the multivariate-adjusted relative risk, was 1.11 (95% confidence interval = 0.76-1.64; P for trend 0.78) for alcohol and 0.86 (0.61-1.20; 0.44) for total caffeine. However, intake of caffeinated soft drinks was positively related to ovulatory disorder infertility. Comparing the highest to lowest categories of caffeinated soft drink consumption, the RR was 1.47 (1.09-1.98; 0.01). Similar associations were observed for noncaffeinated, sugared, diet, and total soft drinks. Our findings do not support the hypothesis that alcohol and caffeine impair ovulation to the point of decreasing fertility. The association between soft drinks and ovulatory disorder infertility seems not to be attributable to their caffeine or sugar content, and deserves further investigation.

To compare specific nutrient intake between normospermic and oligoasthenoteratospermic patients attending infertility clinics in two Mediterranean provinces of Spain. Case-control study. Private fertility clinics in southeastern Spain. Thirty men with poor semen quality (case subjects) and 31 normospermic control subjects of couples attending our fertility clinics. We recorded dietary habits and nutrient consumption using a food frequency questionnaire adapted to meet specific study objectives. We calculated nutrient intakes by multiplying the frequency of use for each food by the nutrient composition of the portion size specified on the food frequency questionnaire and by addition across all foods to obtain a total nutrient intake for each individual. Semen quality was assessed by measuring volume, concentration, motility, and morphology. Hormones levels were also analyzed in case and control subjects. In the logistic regression, control subjects had a significantly higher intake of carbohydrates, fiber, folate, vitamin C, and lycopene and lower intakes of proteins and total fat. A low intake of antioxidant nutrients was associated with a poor semen quality in this case-control study of Spanish men attending infertility clinics.
