MgH2 alleviated irradiation-induced reproductive system damage. The changes in body weight (A) and the appearance (B) and index (C) of the mouse testes were assessed on the 29th day after exposure to 5 Gy whole body irradiation. Then, H&E staining was performed at different time points (0, 1, 29, 35 d) after 5 Gy irradiation of the testes of mice (D). Additionally, the epididymis was stained with H&E (E) on the 29th day, and the sperm density in each epididymal tubule was measured (n = 30) (F). 35 day after irradiation, the thickness of each seminiferous tubule was measured (n = 20) (G). The CCK-8 assay was used to monitor the viability of GC2 (H) cells exposed to 10 Gy irradiation and different concentrations of MgH2. Viability was measured at 450 nm. The data are expressed as the mean ± SEM, *p < 0.05, **p < 0.01
