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.
输出小管位于睾丸头端与附睾头之间。这些小管高度盘曲，形成一个锥形团块，嵌入附睾头I区附近的致密不规则结缔组织中。3至32周时，上皮以单层柱状细胞为主，夹杂少量立方细胞，而在发育后期，主要是立方细胞，夹杂少量柱状细胞。在一些小管中还观察到基底细胞衬于基底膜。细胞无纤毛，小管周围无平滑肌。在出生后不同研究阶段的输出小管上均显示出PAS反应性碳水化合物、糖原、酸性粘多糖、碱性磷酸酶。
