Endogenous antioxidant DJ-1:A potential target for asthenozoospermia

Asthenozoospermia is a common cause of male infertility and is characterized by reduced forward motility of spermatozoa. The pathogenesis of asthenozoospermia remains unclear. DJ-1 is a ubiquitous protein, widely expressed in the liver, skeletal muscle, kidney, brain and testis. It has been found correlated with many diseases including male infertility. This review presents the novel concept that the endogenous antioxidant properties of DJ-I in sperm is associated with asthenozoospermia. Thus, DJ-l is likely a new target for the treatment of asthenozoospermia.
