6 Cadmium (Cd) is a highly toxic environmental pollutant known to cause severe damage to the male reproductive system. This study aimed to investigate the protective effects of bee bread (BB), a natural product with anti-oxidant, anti-apoptotic, and anti-inflammatory properties, against Cd-induced testicular toxicity in male Wistar rats. A total number of 32 rats were divided into four groups, including control, BB (0.50 g kg-1), Cd (5.00 mg kg-1), and Cd + BB (5.00 mg kg-1 and 0.50 g kg-1, respectively) groups. Administrations via oral gavage were performed for 4 weeks. Semen analysis revealed significant reductions in sperm motility and density along with increases in abnormal and dead sperm ratios in the Cd and Cd + BB groups compared to controls. Histopathological examination showed severe degeneration and desquamation of germ cells, tubular atrophy, and a decrease in spermatozoa in the Cd-treated groups. Polymerase chain reaction analysis indicated up-regulation of apoptotic markers (caspase-3,-8, and-9) and oxidative stress enzymes (catalase and superoxide dismutase) in the Cd group, signifying disrupted testicular function. The BB administration partially mitigated Cd-induced damage as evidenced by less severe histopathological changes and moderated gene expression alterations. However, the protective effects of BB were not sufficient to completely counteract the toxic impact of Cd. The present study concluded that while BB had potential in reducing Cd-induced testicular toxicity, its protective efficacy was limited, warranting further research to explore its therapeutic potential in combination with other protective agents.
