The presence of a sperm granuloma at the vasectomy site prevents epididymal pressure build-up, perforation, and the formation of an epididymal sperm granuloma. It thus enhances reversibility of the vasectomy and lessens the likelihood of epididymal discomfort. In two prospective vasectomy series, a sperm granuloma was intentionally allowed to form by not sealing the testicular end of the vas. The sperm granuloma resulted in no instance of orchialgia, but created a greater risk of spontaneous recanalization. This latter problem could only be solved by more careful sealing of the upper end of the vas. In a separate series of nine patients vasectomized elsewhere and specifically referred to us for chronic and persistent postvasectomy orchialgia, seven had no sperm granuloma at the vasectomy site. Pain in these cases was localized in the epididymis and was relieved by vasovasotomy. Any technique of vasectomy carries a very small risk of orchialgia, whether due to the presence of a sperm granuloma at the vasectomy site or to increased epididymal pressure.
