Microsurgery in andrologic urology. II. Alloplastic spermatocele.
Experimental studies in rats and bulls demonstrated the feasibility of using a silicone-Dacron prosthesis as a sperm reservoir in cases of excretory azoospermia. In the study of bulls, 50% of the cows inseminated with spermatozoa aspirated from the alloplastic spermatocele conceived and delivered healthy calves. The clinical results of a series of 14 humans suffering from excretory azoospermia not treatable by other means (e.g., epididymovasostomy or vasovasostomy) also are presented. THe aspirations from these spermatoceles produced motile spermatozoa; however, none of the patients'p spouses conceived after insemination.
