title: The mechanism of spontaneous recanalization of human vasectomized ductus deferens.
abstract: The longitudinal and serial histologic sections of spontaneously recanalized ductus deferens and those of the contralateral ductus deferens displayed many tortuous epithelial tubules growing from the mucosal epithelium of distal stumps intruding into the fibrous scar tissue toward proximal stumps. One of the growing gland-like tubules might perform the spontaneous recanalization.
