What is this investigation & what does it show?









































This is a bilateral vasogram, performed under general anaesthetic, in an azoospermic patient. It shows normal vasa but the seminal vesicles are distended due to congenital obstruction of the ejaculatory ducts. The absence of seminal fluid fructose is characteristic of this condition because fructose is produced only in the seminal vesicles. Endoscopic incision of the ducts usually results in restoration of fertility. After such treatment, this patient fathered two children and, later, requested vasectomy.
There is now a move away from surgery in most men with obstructive azoospermia towards testicular/epididymal sperm aspiration & assisted conception.
