Training, experience and technique are extremely important to the success of the vasectomy reversal. However, the cause of the blockage (e.g., vasectomy, infection or trauma) and whether a unilateral (single side) or bilateral (both side) connection can be made is also very important. Your particular situation might affect your results. This is one reason why the consultation prior to the procedure is so important – to give you the realistic ‘success rate’ for your particular situation.

In addition, how one defines vasectomy reversal success varies. The presence of any sperm in the ejaculate? The presence of a normal amount of sperm with proper motility? A successful pregnancy with ejaculated sperm? A pregnancy through use off assisted reproduction efforts?

I have listed below the percent of men, from my last 250 cases, that have had sperm in their ejaculate within the first year after their procedure. Infrequently, the connection ‘closes down’ resulting in no sperm being present in the ejaculate. It is for this potential occurrence that I recommend banking sperm obtained during the surgical procedure and after sperm is found in the ejaculate.

Many of the microsurgical procedures I have performed are for redos of unsuccessful procedures of other surgeons and for cases in which there is unusual (do to a birth anomaly) or distorted (due to trauma, infection) anatomy. These complex procedures are included in the following results.
% of men with sperm in their ejaculate within one year after:
Bilateral Vasovasostomy: 98%
Unilateral vasovasostomy: 85%
Bilateral Vasoepididymostomy: 75%
Unilateral Vasoepididymostomy: 70%
