[Intraserosal proximal hemideferentectomy versus classical proximal hemivasectomy in the rat. Anatomo-functional aspects and proposal for a new terminology].

: According to new trends and terms in microsurgery, the intra-serous proximal hemideferentectomy is compared to the classical vasectomy in rat. The effects of these surgical models are evaluated on morphological and functional bases. The anatomo-pathological parameters considered (stenosis and leakage of the anastomosis of the epididymal tubule conseguent on local ischemia) have been correlated with functional parameters "in vitro" (spontaneous motility and field stimulation) in order to plan the best microsurgical procedure in the experimental tubulo-vasostomy.
