Nutraceuticals are used as prophylactics and remedies for genitourinary maladies in domestic animals and have been used throughout recorded history. They are also used to control and improve reproductive performance, improve the storability of semen and enhance ovum maturation, and improve in vitro fertilization. In the last decade, the effects and mechanisms of oxidative stress on reproductive performance and immune dysfunction have been elucidated. The antioxidative effects of certain nutraceuticals during periods of the reproductive cycle with high oxidative stress improve reproductive performance and reduce infections and other gentiourinary diseases. This chapter also reviews the current use of nutraceuticals to prevent and treat genitourinary diseases.
