Vasography (original) (raw)

Vasography is an X-ray study of the vas deferens to see if there is blockage, oftentimes in the context of male infertility. An incision is made in the scrotum, contrast is injected in the vas deferens, and X-rays are taken from different angles. Thus, it is an invasive procedure and carries risk of iatrogenic scarring and obstruction of the vas. Vasography has traditionally been considered the gold standard imaging modality for evaluating the seminal tract patency.
