Cadmium is one of the heavy metals with severe reproductive toxicity, whose half-life lasts 20 to 40 years. Cadmium could induce dysfunction of testis and epididymis for its significant accumulation in human testis, and the amount, motility parameters and morphology of sperm change abnormally. The adverse change could also extend to male offspring and cause the impairment of their reproductive system. There has been no clear mechanism of how cadmium induces dysfunction of male reproductive system, and treatment for the adverse influence on male reproductive system by cadmium has not yet been found. Therefore, this problem has been discussed in reproductive and environmental field for a long time. A number of previous investigations showed that cadmium could damage male fertility by followed pathways, including interfering with hormone secretion, inducing oxidative stress, activating inflammation and apoptosis, and causing energy metabolism disorder, etc. In order to enlighten new ideas for therapeutic targets of male reproductive function damage induced by cadmium, we systematically reviewed and summarized the findings of previous publications in this paper.

Cadmium (Cd) is a kind of toxic environmental pollutant. Cadmium pollution is not only a problem endangering the health of poultry production, but also a public health issue related to the safety of animal source food. In this paper, the current situation of cadmium pollution in poultry breeding indus‐ try, the toxic effects of cadmium on poultry, the molecular mechanism of cadmium toxicity and nutrition intervention control techniques were reviewed, in order to provide reference for ensuring the health of poultry production.
