Summary Arsenic is an environmental toxicant which causes mutagenic, teratogenic and carcinogenic defects. It is used as herbicide, fungicide and rodenticide and results in contamination of air, soil and water. Arsenic is also produced through burning of coal industries. The sludge of factories contaminates the fodder and drinking source of water of human and livestock. Arsenic binds thiol groups in tissue proteins and impairs the function of the proteins. This metal affects the mitochondrial enzymes and interrupts the production of energy. Oxidative stress and the generation of reactive oxygen species could also be a consequence of arsenic exposure. High arsenic level may suppress the sensitivity of gonadotroph cells to Gn RH as well as gonadotropin secretion by elevating plasma levels of glucocorticoids. These ultimately lead to the development of gonad toxicity in animals and cause the reduction in sperm number, sperm viability and motility. Massive degeneration of germ cells and alterations in the level of LH , FSH and testosterone are also reported. The objective of this review was to find out the effects of arsenic‐induced toxicity on male reproductive system in animals and its amelioration.
