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.

The influence of individual lifestyle factors is widely described in studies on semen quality. However, their synergistic effect is often neglected. The aim of the study was to examine the association between semen quality and dietary approaches to stop hypertension (DASH) diet, physical activity (PA), and the two separately and in combination. A cross-sectional study was carried out among 207 men aged 20–55. Dietary data were collected by a food frequency questionnaire (FFQ) and analysed according to the DASH scoring index. Physical activity was evaluated by the International Physical Activity Questionnaire. Semen parameters were assessed via the computer-aided semen analysis (CASA). Adherence to the DASH diet was associated with higher sperm count (ΔT3-T1 = 82.1 mln/ej) and concentration (ΔT3-T1 = 24.6 mln/mL). Higher PA was related to higher sperm count (ΔT3-T1 = 69.4 mln/ej), total (ΔT3-T1 = 11.9%), and progressive motility (ΔT3-T1 = 8.5%) and morphology (ΔT3-T1 = 2.8%) in the crude model and remained significant after adjustment. The combination of the DASH diet and PA, was significantly positively associated with sperm count (ΔT3-T1 = 98.1 mln/ej), sperm concentration (ΔT3-T1 = 17.5 mln/mL), total (ΔT3-T1 = 11.8%), and progressive motility (ΔT3-T1 = 10.0%) and morphology (ΔT3-T1 = 3.3%) in both models. Adherence to the DASH diet was related to higher sperm count and concentration, whereas after its combination with physical activity it was also positively correlated with sperm motility and morphology.

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.

The etiology of diminished sperm quality in about 30% of male infertility cases generally remains unexplained. Some studies have suggested that specific nutritional factors can affect semen quality. The aim of this study was to evaluate an association between dietary patterns (DPs) and the risk of abnormal semen quality parameters in men. This cross-sectional study was carried out in 114 men aged 20–55 years from Poland. Semen parameters were assessed via computer-aided semen. Diet was assessed by a food frequency questionnaire (FFQ). DPs were derived using Principal Component Analysis (PCA). Two DPs were derived: Pro-healthy and Western. After adjusting for potential confounders, the risk of abnormal progressive motility was significantly higher in the middle (OR: 2.89, 95% CI: 1.03–8.09) and upper (OR: 7.78, 95% CI: 1.52–15.06) tertiles of the Western DP. A trend for increased risk of the abnormal total count, progressive motility, and morphology (P-trend < 0.050) was found in Western DP. To conclude, the Western DP may increase the risk of abnormal semen parameters, whereas no association was found in the case of Pro-healthy DP. These findings stand in contrast to an increasing number of research findings indicating a positive relation between intake of healthy foods or diet and semen quality parameters. The results highlight the need to study whether modifications in diet and lifestyle factors improve semen quality.

Abstract Background: There is growing interest in the potential impact of the physical environment on human fertility. This study aimed to explore the association between built environment and semen parameters among men who sought fertility evaluation . Methods: This is a cross-sectional study involving 5,886 men living in the Seoul Capital Area whose semen was tested at a single fertility center during 2016–2018. Environmental exposures evaluated were distance to fresh water (river and lake), the coast, major roadways, and neighborhood greenness measured by Normalized Difference Vegetation Index (NDVI). Outcome indicators were semen volume, sperm concentration, percentage of progressive motility, vitality, normal morphology, and total motile sperm count. We used linear regression to model standardized values of six semen quality indicators.Results: Majority of the study population (mean age 39 years) were white-collar workers, clerks, and service workers. None of the mean values of semen quality indicators showed linear trends across quartiles of built environment components. Linear associations between built environment features and semen quality indicators were not evident except for NDVI within 500 m and sperm vitality (β = 0.05 per 0.1-increase; 95% confidence interval (CI): 0.01, 0.09). The 2nd quartile of distance to fresh water was associated with lower progressive motility compared to the 1st quartile (β = −0.10; 95% CI: −0.17, −0.03). Proportion of vitality was higher among men in the 2nd quartile of distance to roadways than those in the 1st quartile (0.08; 95% CI: 0.01, 0.15). Men in the 2nd quartile of NDVI showed higher total motile sperm count than those in the 1st quartile (0.09; 95% CI: 0.01, 0.17). In multi-exposure model, the positive association between NDVI and vitality remained (0.03, 95% CI: 0.00, 0.06). Conclusions: This study contributes potential evidence regarding the impact of built environment on male fertility ; specifically, a positive association between residential greenness and percentage of sperm vitality among Korean men with a history of infertility .

Abstract Objectives: There is no report about association of anxiety on sperm quality during the COVID-19 epidemic. Purpose of this study was to investigate the relationship between anxiety and sperm quality during the COVID-19 outbreak in China.Methods: 896 sperm donors from 7 sperm banks in China were investigated, and passed the screening for sperm donation between 23 January 2020 and 8 June 2020. Semen quality analysis follows the standards of the WHO Fifth Edition Human Semen Examination and Processing Manual. Anxiety symptoms were assessed by the Generalized Anxiety Disorder Scal-7(GAD-7). Logistic regression and linear regression were used to identify the association between anxiety level and sperm quality.Results: Participants with anxiety status (N = 155; 17.3%) had lower sperm concentration (56.81 ± 32.70 vs. 47.21 ± 30.76 [106/mL]), sperm volume (3.58 ± 1.65 vs. 3.04 ± 1.69 [mL], P < 0.001), total sperm count (7.29 ± 1.23 vs. 6.56 ± 1.63 [106], P < 0.001), and progressive motility (50.86 ± 12.45 vs. 38.50 ± 17.00 [%], P < 0.001) than those without anxiety. Linear regression showed that anxiety symptoms was significantly associated with 8.13 (95% confidence interval [CI]: 2.51, 13.75), 0.49 (0.20, 0.79) ,51.05 (23.43, 78.68) and 12.15 (95% CI: 23.43, 78.68), reduction in sperm concentration, semen volume, and total sperm count and progressive motility respectively.Conclusions: This study revealed that anxiety symptoms were negatively associated with semen quality, and interaction was discovered between debt stress and anxiety.

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.
