The present study includes histological, histochemical and ultrastructural studies on the kidneys and testes of two common insectivore species recorded in Egypt, the Hemiechinus auritus and Crocidura flavescens.
In the two investigated species, the urinary system consists of two kidneys, the ureters, the urinary bladder and the urethra. Grossly the kidneys are paired structures of characteristic shape. It is situated in the dorsal side of the abdominal cavity. The right kidney is generally at a higher level than the left one.
In hedgehog the ovoid shaped testes are located in the abdominal cavity throughout life, lying on each side of the urinary bladder just beneath the body wall, no scrotal pouches can be detected. While, in shrew the testes lie in the scrotum outside the body cavity at the base of the tail.
The obtained results showed great similarities in the structure of the testes and kidneys of the two studied animals. However, some differences were recognized including the thickness of renal papilla, size of glomeruli and seminiferous tubules, the thickness of tunica albuginea as well as the histochemical profile of carbohydrates and proteins. These differences may be related to the differences in environmental factors.
