This research investigated the influence of selenium nanoparticles (SeNPs) on the reproductive performance of male Sprague-Dawley (SD) rats. A suspension of SeNPs was consecutively administered by oral gavage for 2 weeks at supranutritional (0.2, 0.4, or 0.8 mg Se/kg bw) and nonlethal (2.0, 4.0, or 8.0 mg Se/kg bw) levels to male SD rats. The normal control (NC) rats were exposed to physiological saline alone. Biochemical parameters, sperm motility, gene expression of GPx1 and GPx4, and histopathological evaluation of male spermary were measured in this work. The supranutritional doses could promote the sperm motility (P < 0.001) and movement parameters (P < 0.05). The nonlethal levels of 4.0 and 8.0 mg Se/kg bw reduced the testis weight (P < 0.001), sperm concentration, and motility (P < 0.05), and also caused histopathological injury of testis and epididymis tissues to various degrees. The content of testosterone in serum was increased in the 0.8 group (P < 0.05) and decreased in the 4.0 (P < 0.01) and 8.0 mg Se/kg bw groups (P < 0.001), respectively. No significant effects were observed on antioxidant enzyme activities and mRNA concentration of GPx in the supranutritional dose group, and nonlethal levels were also not observed. In conclusion, SeNPs in the supranutritional dose has a positive effect on the reproductive function of male SD rats and has damaging effect higher than 4.0 mg Se/kg bw.
