Background: Pollution of the aquatic environment by inorganic and organic chemicals is a major factor posing serious threat to the survival of aquatic organisms including fish. Lake Manzala (LM) is one of the Egypt’s northern Delta Lakes situated on the Mediterranean Coast of the Delta. It is affected by drainage water polluted by different heavy metals that their concentrations exceed the maximum world permissible levels. Aim: This study aims to study the testicular histopathological alterations of Oreochromis niloticus using light microscope and the mature sperm using TEM during spawning season in LM. Materials and methods: Samples of water and 48 specimen of Nile tilapia, Oreochromis niloticus about 14-20 cm in length were collected from two areas; Demitta branch of river (RN) at Mansoura city as a control site and LM as a polluted area during the spawning season..
