[Study on reproductive toxicity of nano-cadmium sulfide with different particle sizes on male mice].

To investigate the reproductive toxicity of cadmium sulfide nanoparticles (Nano-CdS) with different particle sizes on male mice. In January 2019, 30 SPF grade male mice were randomly divided into a control group, an experimental group[CdS Ⅰ group (particle size approximately 5 nm), and a CdS Ⅱ group (particle size approximately 50 nm) ], with 10 mice in each group. The experimental group was orally gavaged with 100 mg/kg, once a day, while the control group was gavaged with an equal volume of physiological saline for 45 consecutive days.
