This paper studied a potential hazard of titanium dioxide nanomaterials in the primary sreening methods on the sample of bull sperm. A method for stabilizing metal nanopowders and their derivatives for biomedical studies is proposed. It was found that the complex of titanium dioxide doped with silver (Ag-TiO2) and nanopowder of titanium dioxide (TiO2) at concentrations of 3 mg/ml initiate pathological changes in the bull sperm: the release of phospholipids as a result of the destruction of membranes and morphological abnormalities (abnormalities of the head, middle part, and tail, as well as the absence of acrosome, etc). The pathological effect of Ag-TiO2 nanocomposite was more pronounced. Doping with silver can increase the toxicity of nanotitanium dioxide, which requires further in-depth experimental studies using different concentrations by in vivo and in vitro methods.
