<p><strong>Background and Objectives</strong></p><p>The toxic effects of zinc leading to sebaceous gland closure, skin eczema and blister have been previously demonstrated in other studies. The aim of this study is to determine the chronic effects of zinc chloride (ZnCl<sub>2 </sub>)  on testicular tissues, testosterone and gonadotrophins in adult male Wistar rats.</p><p> </p><p><strong>Methods </strong></p><p>Twenty four Adult male Wistar rats were divided in to two groups of study and control with each group consisting of 12 rats. Study group rats received 10 mg/kg interaperitoneal Zinc chloride in normal saline (N.S) every other day for 30 days. Control group rats received N.S during this time. Blood sample for hormonal evaluation were collected from hearts of these rats. The rats were destroyed and their testes were removed and fixed in a 10% formaldehyde and glutaraldehyde solution.</p><p> </p><p><strong>Results</strong></p><p>The results of this study showed a significant decrease in the level of LH and testosterone hormone among the rats in the study group compared to the control group with p&lt; 0.001  and</p><p>p&lt; 0.01 respectively. Study of fine structure of testicular cells and tissues in the study group rats  revealed swelling of mitochondria, increase in smooth endoplasmic reticulum vacuolization and lysosomic granules (Autophagic vacuoles) in cytosol of their germinal cells.<strong></strong></p><p> </p><p><strong>Conclusion</strong></p><p>Based on the results of this study consumption of large amount of compounds which contain zinc should be controlled and limited among men. There is a need for further studies to evaluate and determine the reversibility of most hormonal and physiological changes due to usage of zinc containing compounds.</p>
