Ultrastructural changes in Sertoli cells adjacent to efferent ductules were observed before and during sperm transport in Rana porosa porosa. In control frogs, the lumina of seminiferous tubules were not linked with the lumina of efferent ductules. Sertoli cells adjacent to efferent ductules were in close contact with the ductule cells, and no tubule lumen opened into the efferent ductules. After hCG treatment, dilation of the Sertoli cells was observed, and the lumina of seminiferous tubules and the lumina of efferent ductules were linked. Spermatozoa were then seen in the efferent ductules. Thus, the present observations indicate that Sertoli cells adjacent to efferent ductules act as a valve-like device for sperm transport from the seminiferous tubules to the efferent ductules in frogs.
