Artificial spermatocele persisting for 14 years

In a patient with azoospermia secondary to bilateral agenesis of the vas deferens an artificial spermatocele was constructed from the tunica vaginalis testis. The sperm reservoir has been in place for 14 years with its size and the quality of the aspirated semen unchanged. A total of 70 aspirations performed during this period yielded mean volumes of 0.7 +/- 0.24 ml. with a sperm density of 60 +/- 14.7 million per ml. Sperm morphology was normal and sperm motility, although markedly decreased, responded well to stimulation by a motility enhancer. The patient did not have antisperm antibodies.
