We examined 11 patients with acquired obstructive azoospermia resulting from irreparable obstruction of 1 vas deferens and severe damage to the contralateral testis. All of the patients underwent transseptal crossed vasovasostomy with no morbidity. Of 8 patients evaluated with postoperative semen analyses 4 (50 per cent) demonstrated total sperm counts of 29 to 205 million and 2 pregnancies (25 per cent) have been reported, with followup ranging from 5 months to 2 years. The etiologies of the vasal obstruction included previous inguinal surgery in 7 patients, vasectomy in 1, ejaculatory duct obstruction in 1, ectopic ureter in 1 and vasal agenesis in 1. Factors leading to loss of the contralateral testis were torsion in 5 patients, mumps orchitis in 2, varicocele in 1, pediatric inguinal herniorrhaphy in 1, epididymal blow out in 1 and unknown in 1. A representative case involving a unilateral ectopic ureter emptying into the seminal vesicle and subsequent contralateral testicular torsion is presented. The results indicate that a transseptal crossed vasovasostomy should be done in patients satisfying the criteria presented.

The auto-allergic lesion in guinea pigs inoculated with homologous testis plus the Freund adjuvant was investigated histologically. The lesion was found to consist of disseminated foci of perivenous inflammation, lymphocytes and histiocytes predominating in the cellular infiltrate, with invasion of epididymal, rete, and seminiferous tubules and destruction of tubular contents. Guinea pigs up to 800 gm. showed a rapidly progressing diffuse hypo- or aspermatogenesis, which appeared to be secondary to the inflammatory disease. In these animals, the process resolved leaving an atrophic testis with few or no indications of the preceding inflammation and fibrotic scarring only in the rare instances in which actual necrosis of connective tissue elements had occurred. In 1200 gm. animals there was no general hypospermatogenesis and the late findings were limited to foci of aspermatogenesis. This disease then is an experimental auto-allergic orchitis followed by testicular atrophy without scarring. Its morphologic similarity to mumps orchitis and to sterility with "germinal cell aplasia" in man is commented on.
