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 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 STUDY QUESTION Is testicular function associated within father–son pairs? SUMMARY ANSWER Familial resemblance in testis volume and serum markers of spermatogenesis was observed in father–son pairs. WHAT IS KNOWN ALREADY Studies suggest familial clustering of male subfertility and impaired spermatogenesis, but in men from the general population little is known about concordance in testicular function between fathers and sons. STUDY DESIGN, SIZE, DURATION This cross-sectional study with simultaneous collection of data in fathers and sons included 72 pairs (144 fathers and sons), unselected regarding testicular function were included. PARTICIPANTS/MATERIALS, SETTING, METHODS A subgroup of men from the background population and participating in a study on testicular function were asked permission to invite their fathers to participate in a similar setup. Fathers (median age of 53 years) and sons (median age of 19 years) participated in the same study setup including assessment of testis size, having a blood sample taken and analysed for serum levels of reproductive hormones (FSH, inhibin B, LH, testosterone, oestradiol, sex hormone-binding globulin (SHBG) and calculated free testosterone) and delivering a semen sample for assessment of traditional semen parameters. Mixed-effects models were fitted to estimate the familial resemblance as the proportion of variance in markers of testicular function due to shared factors for fathers and sons accounted for using random-effects. Variance components were calculated from both unadjusted and adjusted models. MAIN RESULTS AND THE ROLE OF CHANCE After adjustments, variance component analyses showed that familial resemblance between fathers and sons accounted for 48% (P < 0.001) of the variation in testicular volume, 32% (P = 0.009) of the variation in FSH, 31% (P = 0.009) of the variation in the inhibin B/FSH ratio, 33% (P = 0.007) and 45% (P < 0.001) of the variation in testosterone and free testosterone, respectively, and 31% (P = 0.009) of the variation in SHBG. None of the semen parameters were associated within father–son pairs. LIMITATIONS, REASONS FOR CAUTION The present study may have lacked power to detect associations for semen quality, as large intra- and inter-individual variation occur in semen parameters. WIDER IMPLICATIONS OF THE FINDINGS In this study, testis volume, serum testosterone and serum markers of spermatogenesis including FSH were associated in fathers and sons, suggesting an impact of paternal genetics for testicular function in the son. However, the estimated familial resemblance for spermatogenesis markers highlights that other factors, such as maternal genetics and prenatal as well as adult exposures, are also of major importance for testicular function. STUDY FUNDING/COMPETING INTEREST(S) The study has received funding from Danish Health Authority, Research Fund of the Capital Region of Denmark and Independent Research Fund Denmark (8020-00218B). None of the funders had any role in the study design, collection, analysis or interpretation of data, writing of the paper of publication decisions. The authors have nothing to disclose.

Introduction: Semen analysis is an initial basic step in evaluating and diagnosing male infertility. Multiple risks factors in combination or alone are responsible for abnormal semen parameters. The present study aimed to study certain risk factors and semen parameters of infertile male. Methods: It was a descriptive cross-sectional study. We consecutively enrolled 186 male partners of infertile couple who underwent certain risk factors evaluation and semen analysis according to WHO guideline. Results: Multiple risk factors were present like Gulf country migration, smoking, chemical exposure and heat exposure in infertile male partners. Forty six percent of our patients were gulf workers. Eleven percent patients had azoospermia, 27% had abnormal sperm morphology and 23% had <25% motile spermatozoa. Conclusions: Surprisingly 46% of our patients were Gulf country workers and abnormal semen analysis is very important factor for infertility. Large prospective studies need to be carried out involving Gulf migrant workers only.
