Vaso-vasostomy and Epididymo-vasostomy
Vaso-vasostomy (vas-vas.) and epididymo-vasostomy (ep-vas.) are the standard methods of joining parts of the male genital tract to overcome obstruction of the outflow from the testicles. Experience with vasectomy reversal has shown that, with a careful vas-vas. technique, very successful results can be obtained, restoring fertility in a high proportion of cases. With ep-vas., on the other hand, results have generally been rather poor, even discouraging. These two procedures are technically different, but it is probably a mistake to assume that failure after ep-vas. is necessarily due to surgical problems alone. Instead, the surgeon should consider the underlying pathological conditions that necessitated the operation, which are different in the various parts of the male genital tract, and which are probably more important as the fundamental causes of treatment failure.
