[Improving effect of selenium on spermatogenesis in mice with cyclophosphamide-induced spermatogenic impairment and its underlying mechanism].

Selenium deficiency causes the reduction of the SLC7A11 and GPx4 gene levels, disorder of ferroptosis-related genes and down-regulation of the GPx4 protein expression in the mouse testis and spermatocytes. Selenium can promote the expression of GPx4, up-regulate the level of SLC7A11, and improve spermatogenesis in the testis of the mouse with SI. There are differences between organic SeM and inorganic SeS in regulating the ferroptosis pathway-related genes.
