Abstract
Herein is presented a new technique to construct an artificial spermatocele, using monofilament knitted polypropylene wrapped with tunica vaginalis and anastomosed end-to-end to the head or the body of the epididymis. The material was tested in 10 dogs. It did not harm the spermatozoa, the function of the reservoir or the tolerance of the surrounding tissues. Therefore, the material was used in a patient with bilateral congenital absence of the vasa deferentia, while wife became pregnant following cervical insemination. The spermatocele is still functional after 15 months.
