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.
is now a move away from surgery in most men with obstructive azoospermia
towards testicular/epididymal sperm aspiration & assisted conception.
