  Considering the consumption of caffeine as a supplement favored by theathletes and the proof of its long-term abuse effects on male fertility, the purpose of this study was to investigate the effect of moderate aerobic training combined with the conditioning of Sertoli cell media in testicular damage caused by caffeine consumption.For this purpose,30male Wistar rats were tested in5groups.For4weeks, the groups received caffeine at a dose of200 mg/kg orally and group1received of distilled water.42days after that, the conditioned media of Sertoli cells was injected into the efferent ducts of the rats in the treatment group.After8 weeks, mice were sampled.Tissue samples were studied by histomorphometry andSOD,,GPX, TACand MDA.The group under the influence of caffeine compared to the healthy group, significantly(p<0.01).had lower values of seminiferous tubule diameter, epithelium height, interstitial thickness,TAC, SODandGPXand higher values ofMDA. Respectively, the three groups affected by caffeine along with exercise treatment, treatment with media conditioning and exercise along with media conditioning compared to the group affected with caffeine, have higher values of seminiferous tubule diameter, epithelium height, interstitial thickness,TAC, SODandGPX,and MDA values were lower.In the treatment group with media conditioning and exercise, there was a significant difference in the amount of decrease and increase in the mentioned parameters compared to the other two treatment groups (p<0.05).The results of the present study showed that the use of Sertoli cell media conditioning and aerobic exercise at the same time, with synergistic effects, improves the antioxidant defense indices and reduces the harmful effects of caffeine in the testicular tissue of rats..

  Background & Aim: Exposure to suspended particles (PM2.5) and gaseous air pollution poses a serious threat to spermatogenesis in men. However, the specific molecular mechanism behind this remains largely unknown. This study aims to investigate the impact of PM2.5 and gas pollution on various aspects including the oxidant/antioxidant system, oxidative stress and also the changes in the expression level of aquaporin protein through immunohistochemistry and western blotting in testicular tissue were investigated. Materials & Methods: A total of 36 male Wistar rats were randomly divided into three groups: a control group exposed to standard air conditions, a group exposed to gas pollutants alone (Gas), and a group exposed to both gas pollutants and PM2.5 (Gas+PM2.5). All groups were subjected to pollutant exposure for three months, four days a week, and five hours a day. Results: The findings revealed that co-exposure to gaseous pollutants and PM2.5 led to increased concentration of Malondialdehyde (MDA), as well as decreased in aquaporin 9 protein in immunohistochemistry and western blot, compared to the control group. Conclusion: Therefore, exposure to PM2.5 and gaseous pollutants probably provokes oxidative stress in the testis, which leads to the reduction of aquaporin 9 protein through the activation of signaling pathways. Thus, PM2.5 pollution appears to play a crucial role in infertility by disrupting spermatogenesis. Manuscript profile

  Air pollution in different cities of the world, has become a one of the most important environmental problems, which the effect of its on human health, especially fertility, has been considered. This study aims to investigate the impact of PM2/5 and gas pollution on various aspects including the, sex hormone changes, sperm DNA fragmentation and also (MS-HRM) assay of aquaporin 9 gene in testis tissue. After sampling and evaluating the concentration of PM2/5 24 Wistar rats (weight 170 to 200 g ) were used. The animals were randomly divided into three equal groups including the exposure group 1 (received PM2/5 and gaseous pollutants), exposure group 2 (received gaseous pollutants), and the control group (received the air filtered). After 6 months the animals were investigated for hormonal changes such as FSH, testosterone as well as sperm DNA fragmentation and also methylation-sensitive high-resolution melting (MS-HRM) assay was performed. The data obtained showed that the serum level of FSH and testosterone are significantly increased and decreased in the exposure group 1 compared to the control group, respectively. The exposure group 2 also significantly showed lower the testosterone level than that of the control group. A significant difference was also seen in both exposure groups 1 and 2 with the control group respected to sperm DNA fragmentation. MS-HRM assays detected only hypermethylation of Exposure 1 in comparison with control group in a period of six months. Therefore, exposure to PM2/5 and gas pollutants leads to interference in the secretion of sex hormones and has a detrimental effect on sperm DNA fragmentation, resulting in disruption of male reproductive function, which is crucial in inducing infertility in males. These findings may help in identifying therapeutic targets for reducing human infertility disorders caused by exposure to PM2/5. Manuscript profile
