This study was performed to elucidate the effects of copper poisoning on the reproductive organ of rats. After consecutive oral administrations of copper sulfate, the weights of testis, the numbers and motilities of sperms, organ weights and histological changes of testes were compared between control and experimental groups. 1. Testis weights of 1,000, 2,000 or 4,000 ppm/kg of copper sulfate-administrated rats gradually decreased compared with control group, and the values no significant changes. 2. The sperm numbers of 1,000, 2,000 or 4,000 ppm/kg of copper sulfate-administrated rats were lowered in dose dependent manners than those of control group’s and the values no significant changes. 3, The motilities sperms of 1,000, 2,000 or 4:000 ppm/kg of copper sulfate-administrated rats decreased significantly in dose-dependent manners compared with those of control group′s. 4. The weights of livers and kidneys of 1,000, 2,000 or 4,000 ppm/kg of copper sulfate-administration rats decreased or increased. 5. Necrosis of hepatocytes around the central veins and infiltrations of fine granules-harboring macrophages in periportal and interstitial tissues were found out in the livers of copper sulfate-administrated rats. The Bowman′s capsule and tubules of kidneys were filled with hyaline material.
