| Abstract: | The function of a new experimental microsurgical model of tubulovasostomy is evaluated. The model is represented by an end-to-end tubulodeferential anastomosis after removal of the proximal (juxtaepididymal) half of the vas deferens and segmental unfolding of the distal part of the epididymal tubule. Both anastomosed segments are evaluated for responsiveness to norepinephrine and field stimulation. The results are discussed in terms of accurate selection of segments to be anastomosed on the basis of their morphofunctional correlates; in fact, it seems worth replacing the segments removed only with others endowed with equivalent properties. |
