				Abstract 
 
				
				
				Aim: 
				
				The objective of this study was to investigate the possible 
				protective role of nettle 
				
				Urtica dioica 
				(UD) 
				against Hg-induced toxicity. 
				
				
				Materials and Methods: 
				A 
				total of 28 rats were equally divided into four groups: the 
				control, the Hg (0.8 g HgCl2/kg in the diet), the UD (1.5 ml UD/rat 
				by gavage), and the Hg+UD group. HgCl2 was daily dissolved in 
				distilled water and immediately mixed with the standard diet. A 
				solution of daily infused fresh nettle leaves in boiling water 
				(16 g in 25 ml) was obtained and then it was administrated by 
				gavage. Biochemical and reproductive markers, in addition to 
				glutathione (GSH) level (liver, kidney and testis) and the 
				histological profiles (testis and epididymis) were evaluated 
				after 1 month exposure.  
				
				
				Results: 
				
				Compared to the control, the levels of glucose, triglycerides, 
				urea, creatinine, alanine aminotransferase (ALT), aspartate 
				aminotransferase (AST), and alkaline phosphatase (ALP) were 
				significantly raised in the Hg group. In the latter group, the 
				concentrations of Mg, Fe, and Ca were significantly decreased. 
				Besides, Hg+UD group has only showed raised AST activity and 
				reduced Mg level. Concerning the fertility markers, Hg has 
				provoked a significant decrease in the spermatozoa’s 
				concentration and motility and in plasma testosterone level as 
				well. Furthermore, hepatic, renal and testicular GSH 
				concentrations have declined significantly in the Hg treated rat 
				compared to the control. A remarkable enhancement of the GSH 
				level was observed in all organs of the UD group. The 
				histological examinations of the Hg group have revealed marked 
				testicular degeneration of the most seminiferous tubules, and 
				showed few sperms in the lumen of epididymis ducts. However, the 
				Hg+UD rats have demonstrated an improved histological structure 
				with the presence of important numbers of
				sperms in the lumen. In addition, a clear stabilization of 
				organized seminiferous tubules and an increased sperms’ numbers 
				were noted in the UD supplemented rats. 
				
				
				Conclusion: 
				
				Nettle leaves have not only played a clear protective role 
				during Hg intoxication, but it also enhanced hepatic, renal and 
				testicular GSH level of Wistar rats. 
				
				Keywords: 
				
				biochemical markers, fertility, glutathione, mercury,
