vasography (vayz-og-răfi) 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.
Vasography is a test used to determine the site of possible blockages. A radiographic dye is injected into the vas deferens and ejaculatory ducts. An x-ray image is then taken to observe the flow of the dye through the ducts to determine the site of any blockages. In some cases, an incisional vasography procedure can be performed when the location of a blockage cannot be found through the x-ray examination.
A vasography is a male fertility test in which radiographic dye is injected into the testicles and an image of the testicles. This image shows whether or not any blockages are present. This test is primarily aimed at determining whether or not the sperm-carrying tubes in the testicles – the vas deferens – are obstructed.
The vas deferens are the two tubes which transport sperm cells from the place where they are storied (the epididymis) to the ejaculatory duct (the urethra) which expels semen when a man orgasms. If there is any physical abnormality in the vas deferens, such as an obstruction, this can prevent a man from having active sperm cells in his semen. Therefore, while his sexual function (i.e. his ability to get an erection and reach climax) may appear completely normal, he is actually not capable of expelling sperm cells into his partner’s body, and therefore is unable to get her pregnant.
Vasography is by no means always necessary. It is generally reserved for patients who have had unclear testicular ultrasound exams, but who are also definitely suspected of having a blockage in the vas deferens or other ejaculatory ducts. Other candidates for a vasography exam include:
– Men who ejaculate small amounts of semen in which no sperm cells are present (a condition called azoospermia)
– Men who ejaculate small volumes of semen in which only poor quality sperm cells or sperm cells with poor motility are present
Some men do feel discomfort during a vasography test when the dye is injected into the testicles. Generally, however, any pain experienced is minimal. Many men are much more concerned by the embarrassment of getting undressed and exposing themselves in order for the ultrasound device to be moved around the scrotum. A blanket or cover is provided so that a man can maintain his modesty to some degree. It’s important to remember that the person carrying out the exam has seen it all a hundred times before. Try not to dwell on the embarrassment factor, rather, focus on the main goal: becoming a Dad.
