The sources of origin and the peculiarities of formation of the seminal ducts and rete testis during the prenatal period of ontogenesis in man were studied. It has been established that the seminal duct sand the ducts of the rete testis form from the cellular cords of the coelomic epithelium and the primordial germ cells which appear simultaneously in the septum of the testis and the primordial germ cells which appear simultaneously in the septum of the testis and central part of its parenchyma in the embryos, 13.0--17.0 mm long. By plastic and graphic reconstruction, as well as by methods of subtle preparation under binocular microscope MBC-I control it was revealed that the seminal ducts anastomosed between themselves both within the limits of one and the adjacent lobules. The ducts of the rete testis do not form anastomoses, but superimpose over one another, creating an impression of a rete. Approaching the tunica albuginea they merge, continuing into the cuctuli efferentes testis.
