Vasovasostomy

There are several reasons for this, including blockages in the vas deferens, and the presence of autoantibodies which disrupt normal sperm activity.

The surgeon's goal is to achieve a very precise circumferential reconnection of the sperm canal edges by using meticulously placed microsurgical sutures.

Most urologists specializing in the field of male infertility perform vasovasostomies using an operative microscope for magnification, under general or regional anesthesia.

Unfortunately, surgeons performing only an occasional vasectomy reversal often neglect examining the vas contents for presence or absence of sperm.

The most common cause for failed vasectomy reversals is the inappropriate non-microsurgical technique using sutures that are too large to achieve watertight reconnections.

The failure of a competently performed microsurgical vasovasostomy following the absence of any sperm in the contents of each vas usually is due to “blowouts” in the epididymides.

However, if more than 15 years have passed since the original vasectomy, one may have a lower chance of having enough healthy sperm in one's own semen to father a child.
