Reversal of vasectomy is a difficult procedure. Most surgeons still pe
rform a macroscopic vasovasostomy. However, there is a little guidance
in the current literature on the results that can be expected from su
ch procedures. Patients may therefore be given unrealistic expectation
s preoperatively. Our study shows the results of macroscopic reversals
of vasectomy performed over a 9-year period. A survey of Welsh surgeo
ns is also presented concerning their preferred techniques and estimat
ed success rates for reversals. The study clearly shows that a macrosc
opic vasovasostomy is the commonest method employed, with a wide varia
tion in estimated success rates. Patients considering a macroscopic re
versal of vasectomy should be warned of a less than 20% success rate.
