Postnatal study on the histology and histochemistry of ductuli efferentes testis in buffalo (Bubalus bubalis) from birth to one and a half years.

The efferent ductules were situated between the cranial border of the testis and the head of epididymis. The ductules were highly convoluted and formed a conical mass embedded in the dense irregular connective tissue near region I of the head of epididymis. Simple columnar with a few cuboidal cells characterised the epithelium at 3-32 weeks, whereas in later stages of development it was mainly cuboidal with a few columnar cells. The basal cells were also observed lining the basement membrane in some of the tubules. The cells were devoid of cilia, smooth muscles surrounding the tubules were absent. PAS-reactive carbohydrates, glycogen, acid mucopolysaccharides, alkaline phosphatase were demonstrated on the efferent ductules at different stages of postnatal study.
