Sperm Granuloma and Success Rate of Vasovasostomy

Lee, Sang Kon; Lee, Hee Yong

Abstract

A discrepancy between patency and pregnancy rates persists even if a surgical success rate of vasovasostomy, improved. A sperm granuloma has been considered that it has relation to improvement of quality of sperm by decompression of intravasal pressure. During the period from 1981 to 1983, a total of 160 vasovasostomies were performed. An age of the patient ranged from 24 to 65 with the mean of 36.5. Duration of obstruction ranged from 5 months to 20 years with the mean of 4.2 years. Viable sperms more than 10 x 1,000,000/ml appeared in 145 out of the 160 patients (90.6%) , and pregnancy occurred in 98 out of the 160 patients (61.2%) following the vasovasostomy The sperm granuloma was found in 50% of 160 vasectomized patients. Forty-eight percent of patients whose patency were restored had sperm granuloma. Fifty percent of patients who impregnated their wives had sperm granuloma. There was statistically no significant difference in both patency and pregnancy rates between patients with and without sperm granuloma. But sperm months at 6 months post operatively was found to be higher in patients with sperm granuloma than without sperm granuloma (p<0.05).
