Vasectomy reversal is a surgical procedure that re-approximates the cut ends of the vas deferens, restoring the flow of sperm from the testicle to the prostate. This procedure generally requires an experienced microsurgeon using an operating microscope to achieve the best success rates. A vasectomy reversal can be accomplished in two ways: a vasovasostomy or vasoepididymostomy.
With a vasovasostomy, the surgeon sews the severed ends of the vas deferens back together.
A vasoepididymostomy attaches the vas deferens directly to the epididymis, the coiled tube on the back of each testicle where sperm matures. A vasectomy can cause blockages or a break in the vas deferens or the epididymis. This surgery is used when a vasovasostomy won't work because sperm flow is blocked. The vas deferens is connected to the epididymis above the point of blockage.
Essentially any man who has had a vasectomy is a candidate for vasectomy reversal. The advent of microsurgical techniques makes possible vasectomy reversal at any time after vasectomy. Discomfort is quite variable but typically is not much more severe than the original vasectomy. A Vasectomy Reversal is typically an out-patient procedure (patient goes home the same day).
