title: Structure of rete testis, vas efferens, epididymis and vas deferens of langur monkey (Presbytis entellus entellus Dufresne).
abstract: Morphological and histological features of rete testis, vas efferens, epididymis and vas deferens were studied in the langur monkey. Tubular extensions of rete were located towards lateral side of the testis. Its epithelium comprises mostly of cuboidal cells with hyaline cytoplasm. Three to nine bundles of vas efferens, emerging below the cranial pole of the testis, were observed. Vas efferens epithelium comprises of ciliated and nonciliated cells. Epididymis could be divided into six zones on the basis of cytological features. Principal cells, basal cells, apical cells and intraepithelial lymphocytes were observed in the epididymal epithelium, but their number, shape, size and location of nuclei varied in different zones. Vas deferens epithelium comprises of principal cells, basal cells, apical cells and few intraepithelial lymphocytes. Epithelium is surrounded by lamina propria, longitudinal, circular and longitudinal muscle layers.
