Cadmium is a major environmental toxicant that is released into the atmosphere, water and soil in the form of cadmium oxide, cadmium chloride, or cadmium sulfide via industrial activities, such as the manufacturing of batteries and pigments, metal smelting and refining and municipal waste incineration.

Our study showed that in vitro incubation of human or mouse sperms with cadmium for a long time up to 24 hours could significantly decreased sperm motility in a concentration- and time-dependent manner. Exposure to cadmium in the environment for a short term 30 min did not affect sperm motility but significantly reduced in vitro fertilization rate. We also evaluated the effects of cadmium at concentrations of 0.
