Abstract: The present study had been carried out to elucidate the toxic effects of sodium fluoride on local rabbit males, this study involved determination of the histological Changes of some organs include (Testes, Liver and Kidney) , moreover study the changes in body weight of the animals and the percentage of organs weight and some blood parameters and biochemistry which include packed cell blood volume (PCV), Hemoglobin (Hb), Total white blood cells, Testosterone hormone, T3, T4 hormones, Glucose concentration, Cholesterol, Urea, Transaminase enzymes and Bilirubin - level in blood. Twenty local adult male rabbits were included this experiment their ages ranged between 10 - 14 months.The animals were treated with oral swallow for 12 weeks. The animals were divided into four groups : control group is treated orally with (0.9%) normal saline; First group was treated orally with 10 mg/kg of body weight sodium fluoride, second group was treated orally with 20 mg/kg of body weight sodium fluoride and third group was treated orally with 30 mg/kg of body weight sodium fluoride. The results of present study showed a significant decreased (P<0.05) in body weight of treated animals with dose of sodium fluoride 20 and 30 mg/kg of body weight, while there is no significant differences in the body weights of treated animals with sodium fluoride dosage of 10 mg/kg of body weight when to compared with control group. The percentage of organ weight to body weight showed a significant decrease in testis weights and liver weight, while there was no significant differences in kidney weight in treated group with sodium fluoride when to compared with control group. Concerning histological changes showed a reduction or freezed stages in spermatogenesis processes which timed with decrease in number of primary spermatocytes and secondary spermatocytes in addition to infiltration of lymphocytes, also found that NaF cause disorganization, denudation, and reduction in germinal epithelial cells of the seminiferous tubules and associated with absence of sperm in the lumina, also showed a decrease in radius of epididymus ducts and decrease in number of sterocilia and decrease number of mature sperms. Histological sections of kidney showed that there was a clear shrinkage of glumeruli.Histological section of kidney of animals that treated with sodium fluoride showed a mild blood vessels congestion, shrinkage in glumeruli, distributed in renal tubules and erode its epithelium with some apoptotic areas. The liver sections appeared appreciable effect with fluoride include dilation in central vein and erode to its epithelium, congestion in hepatic sinusoids with apoptosis and erode to general structure of liver with some of inflammatory cells and death in some cells which lead to erode of typical ray arrangement. Regarding blood parameters the present study showed a significant decrease (P<0.01) in percentage of (PCV) and (Hb) of the animals treated with sodium fluoride, while showed (WBCs) count significant increased compared with control group. Hormonal analysis (Testosterone, T3 and T4) showed a significant decrease, while significant increase of glucose, cholesterol, urea, transaminases enzymes for (AST, ALT) and bilirubin levels. Results obtained from this study and mentioned above may be attributed essentially to that of Naf administration results in sever lesion of male reproductive system wich may be aggravated with increase administration concentration of Naf.
