Staining for ER, confined to nonciliated epithelial cells of the efferent ductules, was not affected by postnatal age.
3
ER were confined to nonciliated cells of the efferent ductules, which displayed moderate staining in all animals, beginning from week 1.
4
Testes and efferent ductules were examined at the light and electron microscopic levels in goats from 1-25 weeks of age.
