Basic male reproductive anatomy was studied in eleven alive foxes captured from Sinai desert, representing three species of the foxes 5 adult red foxes (Vulpes vulpes), 5 immature sand foxes (Vulpes ruppellii) and one immature fennec fox (Fennecus zerda). The reproductive organs of all examined foxes were carefully dissected and investigated. As far as the age of the available foxes in each species was nearly similar data regarding weight, dimensions and absence of any segment were recorded for one fox representing each species. The present study declared the absence of ampulla ductus deferens, seminal glands and bulbourethtal glands in foxes. The only present gland is the prostate gland. The present investigation showed a marked difference in weight and length of the different segments of reproductive tract between species which were attributed mainly to age of the animals. The mean serum level of glucose, alkaline phosphatase, choifesterol, total protein, albumin, creatinine, calcium, phosphorus and sodium were estimated in adult red foxes.
