Structural Changes of the Testis and Changes in Semen Quality Parameters Caused by Intraperitoneal and Peroral Administration of Selenium in Rats
The aim of this study was to find the structural changes in the testis and semen quality parameters of rat after a singleintraperitoneal and repeated peroral selenium administration. Rats were killed 36 hours following the intraperitonealadministration of selenium selenite (2 mg.kg-1 b.w.; 98% purit...
