title: [Surgical treatment of distal seminal duct obstruction].
abstract: Transurethral resection of the colliculus seminalis offers a method of removing obstructions in the region of the ductus ejaculatorii. Treatment of post-gonadal azoospermia is problematic since, even if the seminal duct is made passable, the sperm quality remains unsatisfactory. Impairment of sperm motility and spermiogenesis itself is suspected as the expression of an auto-immune reaction to distal obstruction.
