Unlike a vasectomy, however, reversal would theoretically be much simpler and much less expensive, about another $1,000, compared with $5,000-$12,000 for a vasovasostomy
Robotic microsurgical vasovasostomy
and vasoepididymostomy: A prospective randomized study in a rat model," Journal of Urology 171(4): 1720-1725.
In the study, the decision to perform vasovasostomy
or epididymal bypass was determined by the presence of sperm in the vasal fluid.
The pregnancy rate following vasovasostomy
varies significantly, depending primarily on the interval between the vasectomy and the reversal.
Historically, surgeons have relied only on the standard vasovasostomy
to reconnect the vas deferens.
