In order to understand the postnatal developmental events of ductuli efferentes testis, the testis and ductus epididymidis of male Wistar rats in different developmental stages (1-9 weeks) were investigated by histological and immunohistological methods. A large number of cells appeared in the lumen of ductuli efferentes testis during the juvenile period (3-4 weeks). The majority of luminal cells had similar morphology to spermatids and spermatocytes. Some of the luminal cells showed morphological changes such as chromatin condensation and marginalization, and fragmented nucleus when they translocated to the ductuli. TUNEL staining for apoptosis was positive to some of the luminal cells. Small number of luminal cells in the ductuli were immunoreactive to anti-macrophages antibody suggests the appearance of macrophages in these cells. The timing of appearance of the luminal spermatogenic cells and macrophages in ductuli efferentes testis was in coincidence with the epithelial differentiation of DET.
