[Iatrogenic obstructive azoospermia].

Archivio italiano di urologia, andrologia : organo ufficiale [di] Societa italiana di ecografia urologica e nefrologica, 1997
Obstructive azoospermia is a common cause of sterility in men. In the past infection played an important role in the aetiology of obstructive azoospermia. Recently, however, the aetiology of obstructive azoospermia appears to be changing. So iatrogenic obstructive azoospermia has reached an important role in the field of obstructive azoospermia.
