Abstract Objective Infertility had an increasing trend between couples in Iran. Several factors such as lifestyle, physical activity, unhealthy dietary habits and stress are associated with production of ROS in seminal fluid. The aim of this study was to identify the role of dietary antioxidants and vitamins intake on semen quality parameters, among Iranian infertile men. Methods This cross-sectional study was performed on 400 newly diagnosed infertile men in Yazd Reproductive sciences Institute from July 2019 to December 2019. The presence of infertility was confirmed by an expert andrologist, based on WHO criteria. Dietary antioxidants and vitamins intake were assessed using a 168 items semi-quantitative food frequency questionnaire (FFQ). Results We found an association between semen volume and Alpha Carotene dietary intake, total motility and Beta Cryptoxanthin dietary intake, and sperm count with riboflavin intake (P = 0.03). Conclusions We concluded that dietary intake of Alpha Carotene, Beta Cryptoxanthin, and Riboflavin are related to sperm count, semen volume and total motility in Iranian infertile men, respectively. Our data suggest that that adhering to a diet that is rich in sources of antioxidant and vitamin can have a positive effect on men’s sexual health. However, more research is needed to confirm these relations and provide the evidence needed to exert these findings into clinical practice.

Abstract Background The aim of this study was to provide information on the semen quality pattern of infertile men and age thresholds for semen parameters in China. Methods This was a retrospective cross-sectional study investigating 71,623 infertile men from the Reproductive and Genetic Hospital of CITIC Xiangya in Hunan, China, from 2011 to 2017. The Kruskal-Wallis test, Mann-Kendall test, linear regression model and joinpoint regression were used. Results Although erratic changes were observed in the median semen parameters (sperm concentration 40.1–52.1 × 106/ml, total sperm count 117.8–153.1 × 106, sperm progressive motility 33.4–38.1%) during the 7 years of observation, no significant decrease in semen quality was found, and 47.88% of infertile men showed normal semen parameters according to the World Health Organization (WHO) criteria. According to the joinpoint regression analysis, sperm progressive motility appeared to decrease earlier than the sperm concentration and total sperm count (at 28, 58, and 42 years of age, respectively). Conclusions There is no evidence of a deterioration in semen quality among infertile men in Hunan, China. Semen parameters decreased with increasing age, with turning points noted at different ages. Semen parameters are not absolute evidence for the assessment of male fertility potential. Therefore, we believe that, among semen parameters, the sperm concentration is the best predictor of fertility for ART, followed by motility. Decreased sperm motility may affect natural pregnancy, but it is not necessary for successful IVF.

Abstract Study question Is there any association between dietary total antioxidant capacity (TAC) and semen quality parameters in male partners of couples attempting fertility? Summary answer Greater adherence to diets high in TAC was significantly associated with higher total sperm count, sperm concentration, and sperm motility. What is known already Among multiple factors that affect the etiology of poor semen quality and male infertility, dietary factors have an important contribution. Also, chronic oxidative stress negatively effects semen quality. Whether adherence to the diet rich in antioxidants is associated with better semen quality remains largely unexplored.The concentration of single antioxidant cannot show the total antioxidant power of the diet, therefore the concept of dietary total antioxidant capacity (TAC) was invented.Dietary scores are useful approach to evaluate the degree of adherence to specific dietary pattern and its benefits in regard to health Study design, size, duration This was a cross-sectional study of 350 men from couples attending a fertility center in Tehran, Iran, recruited between June 2015 and September 2019. Men aged 25–50 years with complete dietary data were analyzed. Participants/materials, setting, methods Diet was assessed via a reproducible and valid 168-item semi-quantitative food frequency questionnaire to determine the entire antioxidants of the usual diet in order to calculate dietary TAC. Semen quality was assessed according to World Health Organization 2010 guidelines. The association between dietary TAC and semen parameters were assessed adjusting for potential confounders through multiple logistic regression analysis. Main results and the role of chance The average age of study participants was 34.9 ± 7.6 years and their BMI was 28.5 ± 4.3 kg/m2. Participants in the lower tertile of the dietary TAC were lower educated (p < 0.01), more physically active (p < 0.05), and predominantly had abnormal sperm progressive motility (p < 0.01). In the multivariable adjusted models, men in the lowest tertile of the dietary TAC Score had 2.9 times higher likelihood of having abnormal sperm motility, total sperm count and concentration, compared to men in the highest tertile of the TAC score (p < 0.05). Limitations, reasons for caution The main limitation of our study was its cross-sectional design, limiting our ability to derive causal association. Wider implications of the findings: Our study suggests that dietary pattern comprising mainly of antioxidant nutrients may help improve semen quality. Our results are consistent with previous studies showing that plant-based diet contains higher levels of antioxidants are associated with better measures of semen quality.

Abstract Background Previous studies have demonstrated the association between dietary patterns and semen quality indicators, but research on the possible association between animal flesh foods consumption and semen quality is limited. Therefore, this study was conducted to investigate the association between animal flesh foods consumption with semen quality. Methods In this cross-sectional study, 400 newly-identified (< 6 months) infertile men, as diagnosed by an andrologist, were recruited into the study. Dietary intake was assessed by using a semiquantitative Food Frequency Questionnaire. The total meat consumption was defined as the sum of red meat, poultry, fresh fish, canned fish, processed meats, and organ meats in the diet. A linear mixed model was used to assess the relationship between meat consumption and semen quality indicators of participants. Results Consumption of canned fish was inversely related to sperm immotility. Compared with the men in the lowest quartile of canned fish intake, those in the highest quartile had a lower sperm immotility [lowest quartile: 52.5%; (95% CI: 47–57) vs 47.4%; (95% CI: 43–51) P-trend = 0.026]. Similarly, a trend toward an inverse significant association between fresh fish intake and sperm immotility was observed (P-trend = 0.074). In contrast, fresh and canned fish intake was unrelated to other outcomes of sperm quality (P-trend > 0.05). No association was found between consumption of processed red meat, red meat, poultry, and organ meat, and semen quality indicators (P-trend > 0.05). Conclusions We found that consumption of canned fish is associated with a lower percentage of immotile sperm, whilst a high consumption of fresh fish increased the percentage of immotile sperm in Iranian infertile men. Further studies are recommended in this regard.

Background: Varicocelectomy is a type of surgery for varicocele treatment. This may recover fertility properties in males through improvement in semen parameters as well as sexual hormones. In this study, the role of varicocelectomy with focus on semen properties and sexual hormones have been assessed. Methods: In this cross-sectional study, before- after data from fifteen patients with different varicocele grade, regarding to varicocelectomy have been compared. Result: After varicocelectomy, a significant improvement in some semen parameters such as motility and concentration has been showed. However, among sexual hormones, only testosterone has been increased after surgical intervention (p=0.007). Conclusion: Based on our knowledge, varicocele treatment may almost improve fertility potential in males significantly. Accordingly, it seems that varicocelectomy has positive effect on parameters such as testosterone and serum FSH levels as well as sperm count and motility. Therefore, it could be concluded that varicocelectomy is an effective approach to improve male fertility and sexual disorders.

Abstract Objective: Previous studies have proven the effect of dietary patterns on semen quality indicators, but research on the relationship between meat intake and semen quality is limited. Therefore, this study was conducted to investigate the relationship between Meat intake with semen quality.Methods: In this cross sectional study, 400 infertile men were recruited into study during their fertility investigation in Yazd Reproductive Sciences Institute Diagnosed by an andrologist according to the inclusion criteria. Multivariate logistic regression was used to determine the relationship between meat intake and semen parameters. All data were analyzed using SPSS V. 22 software.Results: We found that intake of canned tuna can have two different effects on sperm motility in infertile male. Intake of canned tuna according to the serving size stated in quartile 2, leads to a decrease in the percentage of immotile sperm from 52.93 (CI95%, 51.15-54.71) to 46.55 (CI95%, 44.56-48.54)(Ptrend=0.036). On the other hand, there is an increase in the percentage of immotile sperm from 46.55 (CI95%, 44.56-48.54) to 52.88 (CI95%, 50.94-54.82) in the highest quartile of canned tuna intake.Also, no significant relationship was observed between intake other types of meats and sperm quality indices.Conclusions: We found that intake of canned tuna,base on serving size of quartile 2, is associated with lower percentage of immotile sperm, on the other hand high intake of canned tuna increase percentage of immotile sperm in Iranian infertile men. More extensive studies are recommended in this regard.

Abstract Background: Depression is a potential factor affecting semen quality. However, the relationship between depression and semen quality remains to be fully elucidated. We investigated the association between depression and semen quality in men during the COVID-19 pandemic.Methods: Cross‐sectional, participants completed a questionnaire assessing lifestyle factors the Patient Health Questionnaire-9 (PHQ-9) was used to evaluate the psychological depression status of subjects. Semen quality assessment implements the requirements of the fifth edition of the World Health Organization (WHO )manual ,multivariable logistic regression analysis and linear regression analysis were conducted to assess the associations between depression and semen quality.Results: Of the 896 participants, 173 were depressed (19.30%). A Linear regression model was fitted to assess the strength and significant level of the association between depressive symptoms and semen quality. After adjusting for potential confounders, depression was significantly associated with 9.27 (95% confidence interval [CI] 3.39, 15.15), 0.57(95% CI 0.27, 0.87), 62.20 (95% CI 32.93, 91.48), and 12.96 (95% CI 10.55, 15.37) reduction in sperm concentration, sperm volume, total sperm count, and progressive motility, respectively. Which are consistent with the logistic regression analysis results. The semen concentration and total sperm count were linearly correlated with depression scores, whereas the semen volume and progressive motility of sperm were nonlinearly correlated with depression scores.Conclusions: Depression were associated with lower levels of semen concentration, semen volume, total sperm count, and progressive motility, which could affect male reproductive health.

AbstractSemen quality is a key indicator of male fecundity and therefore is closely related to male fertility. In recent decades a significant decrease of semen parameters was observed worldwide. Except for environmental pollution, low physical activity, body weight and comorbidities, unhealthy diet was linked to semen quality decline. Mediterranean Diet (MedDiet) due to its anti-oxidative and anti-inflammatory properties, is considered as beneficial for semen. However, results of existing studies are inconclusive. The aim of this review was to pool associations between adherence to the MedDiet and semen quality parameters in observational studies. Electronic databases including PubMed, Embase and Scopus were searched until April 2019 with no restriction to language or time. Studies were eligible for inclusion if they filled following criteria: (1) observational design (retrospective or prospective), (2) adherence to MedDiet assessed using score or data-driven method and (3) semen quality parameters (total motility, progressive motility, total count, concentration or volume) as outcomes. Mean differences or odds ratios of abnormal semen parameters between the highest and lowest quintiles of MedDiet were converted to standardized mean differences (SMD). Random effects models with inverse variance method were used to pool differences. Heterogeneity was assessed using the Cochrane Q test and I2 statistic with value > 50% indicating substantial heterogeneity. Five cross-sectional studies extracted from 840 articles, met the eligibility criteria and were included in the meta-analysis. Higher adherence to MedDiet compared to lower adherence was associated with increased total (SMD = 0.59 95%CI: 0.12–1.06, I2 = 80%, pheterogenity < 0.01, n = 4) and progressive (SMD = 0.53 95%CI: 0.16–0.91, I2 = 0%, pheterogenity = 0.94, n = 2) sperm motility. No associations were observed between adherence to MedDiet and total sperm count (SMD = 0.14 95%CI: -0.20–0.48, I2 = 70%, pheterogenity < 0.01, n = 5), concentration (SMD = 0.22 95%CI: -0.04–0.47, I2 = 48%, pheterogenity = 0.10, n = 5), volume (SMD = 0.02 95%CI: -0.20–0.25, I2 = 21%, pheterogenity = 0.28, n = 5), as well as morphology (SMD = -0.10 95%CI: -0.36–0.16, I2 = 38%, pheterogenity = 0.18, n = 4). The results suggest that higher adherence to the MedDiet may have a protective effect on semen quality, probably by increased intake of antioxidant-rich products. Limitations of findings include substantial between-study heterogeneity and use of cross-sectional design. Beneficial effects of the MedDiet on semen quality have to be confirmed in further prospective studies.
