Protective role of glutamine against cadmium-induced testicular dysfunction in Wistar rats: Involvement of G6PD activity.

Background: Endocrine disruptor such as cadmium has been widely reported to cause testicular toxicity, which contributes to recent decline in male fertility worldwide. Glutamine, the most abundant amino acid in the body has been demonstrated to exert protective effects in cellular toxicity. However, its role in testicular toxicity is unknown.
