				Abstract 
 
              Aim: 
              This study was 
              designed to evaluate the prophylactic effect of Nigella sativa
              (NS) treatment on toxic effects induced by lead acetate (LA) 
              on the reproductive hormones, spermiogram and gonadal histology of 
              rats.  
              Materials and 
              Methods: 
              A total of 20 
              Sprague-Dawley rats were divided into four groups of five rats 
              each. Group 1 (negative control [NC]) was the NC and was given 
              distilled water, Group 2 served as the positive control (PC) and 
              was administered 10 mg/kg/day of LA per overall survival (OS), 
              Group 3 (T1) was administered 200 mg/kg/daily of NS per OS for a 
              month, and Group 4 (T2) was pretreated with 200 mg/kg/daily of NS 
              per OS for 1 month, followed by 10 mg/kg/daily of LA alone per OS 
              for another. The rats were euthanized at the end of the 
              experimental period for collection of blood and the right caudal 
              epididymis and testis. Serum was used for determination of 
              reproductive hormones by using radioimmunoassay kits. The 
              epididymal segment was cut and homogenized in phosphate-buffered 
              saline, and the homogenate was used for determination of the 
              spermiogram parameters such as sperm concentration, sperm 
              viability, percentage of live sperm, motility and abnormality. 
              Both the epididymis and testis were fixed in 10% buffered formalin 
              for histological processing.  
              Results: 
              The sperm 
              concentration, general, and individual motilities were higher 
              (p<0.05) in the NC and T1 animals, while the T2 had intermediate 
              and the PC had lower (p<0.05) values of each parameter. The 
              percentage sperm viability was higher (p<0.05) in the T1 and lower 
              (p<0.05) in the PC group. However, percentage abnormality was 
              lower in T1, comparable in NC and T2, and higher (p<0.05) in PC. 
              Spermatogenic cell population and epididymal sperm reserve (ESR) 
              were optimal in control and pretreated animals, while the PC had 
              lower spermatids and ESR. The concentration of estradiol (EST) was 
              lower (p<0.05) in the PC and T2, while leuteinizing hormone (LH) 
              concentration was lower (p<0.05) in the PC, and comparable 
              (p>0.05) between control and T2. The concentration of 
              follicle-stimulating hormone (FSH) was comparable (p>0.05) in all 
              groups, while testosterone (TS) hormone concentration was lower 
              (p<0.05) in the PC and higher in the control and T1 groups. 
               
              Conclusion:
              This 
              study showed the preventive effects of NS administration against 
              alterations in reproductive hormnes, sperm parameters and gonadal 
              histology caused by LA in rats.
