Titanium dioxide nanoparticle-induced testicular damage, spermatogenesis suppression, and gene expression alterations in male mice.

Highlights: [•] Exposure to TiO2 NPs could cross blood–testis barrier and be accumulated in testis. [•] Exposure to TiO2 NPs caused testis and sperm lesions in male mice. [•] Exposure to TiO2 NP decreased sperm numbers and sperm motility in male mice. [•] Exposure to TiO2 NP resulted in imbalance of sex hormones in male mice. [•] Exposure to TiO2 NP caused alteration of 142 genes expression of known function in testis. [ABSTRACT FROM AUTHOR]
