vasography

n.
X-ray imaging of the vas deferens. A contrast medium is injected either into the exposed vas deferens at surgery, using a fine needle, or by inserting a catheter into the ejaculatory duct (which discharges semen from the vesicle into the vas deferens) via an endoscope. The technique is used in the investigation of azoospermia to look for blockages in the vas.
