The testis structural changes after the diazinon intraperitoneal administration of 20 mg/kg b.w., selenium 2 mg/kg b.w. and both diazinon 20 mg/kg b.w. and selenium 2 mg/kg b.w. were evaluated by histological and morphometric methods in light microscopy. 36 hours after the diazion i.p. administration, the vacuolization of the seminiferous epithelium, evacuation of germ cells into the tubule lumen, epithelium necrosis and disintegration, interstitium extension and fibrotization were observed. The germ cells released from the basal lamina and subsequently they were visible in the tubule lumen. Blood vessels were damaged and morphometric analysis have shown their significant dilatation (P<0.05). Diazinon causes the damage of the germinal epithelium in the testes leading to the spermatogenesis failure. The infertility can then appear. In selenium treated group disintegration of cellular associations in the seminiferous epithelium, damaged and separating spermatids lines, reduced spermatogenesis and significant vacuolization of seminiferous epithelium (P<0.0001) were observed. Similar changes as in selenium threated group occured, significant vacuolization of seminiferous epithelium (P<0.05) was seen. In combined diazinon and selenium treated group protective effects of selenium in seminiferous epithelium and interstitium were noticed. Further investigation of diazinon and selenium is needed to practical use this results.</p><p class="MsoNormal">&nbsp;</p><p class="MsoNormal"><span style="font-size: 12px;"><strong>doi:10.5219/44</strong></span></p> <p class="MsoNormal">&nbsp;</p></span></div>
