Dr Dezarnaulds will use a vasovepididymostomy technique for your vasectomy reversal if it is not possible to rejoin vas deferens to vas deferens (vasovasostomy). Generally this occurs when the vasectomy site is low (not common) and the ‘pipe’ carrying sperm has been damaged from the epididymis (upstream) to the vas deferens (downstream).
This microsurgery is more challenging and, because a ‘big pipe’ is being joined to a ‘small pipe’, has a lower success rate. None the less it is sometimes necessary. Dr Dezarnaulds can only make the decision on whether a vasoepididymostomy is needed during your surgery – but it is rarely needed. Most vasectomy reversals are vasovasostomies.

Vasoepididymostomy Success Rate
Vasoepididymostomy is less likely to succeed than vasovasostomy and so will only be utilised when necessary. Patency rates (sperm passing) after vasoepididymostomy are in the order of 50%.
