Transvasovasostomy--an alternative operation for obstructive azoospermia.

Five patients with obstructive azoospermia are presented. They were evaluated by a complete history, physical examination and semen analysis, including fructose studies, and serum testosterone and follicle-stimulating hormone determinations. A history or suspected history of epididymitis or prostatitis was identified in 4 patients and a history of iatrogenic obstruction was found in 3. All patients underwent testicular biopsy which showed normal spermatogenesis. A vasogram was crucial in determining the site of obstruction. All patients underwent transvasovasostomy through the scrotal septum. Patients had encouraging postoperative sperm counts and fertility has been demonstrated by induction of pregnancy in 2 cases.
