Abstract

The sperm count in semen analysis after vasovasostomy is significantly higher in men with vasal fluid in the proximal vas during the operation than in those without fluid on one or both sides(P<0.05). On 8(38.1%) of 21 sides in 12 men without vasal efflux during vasovasostomy secondary epididymal obstructions were found on scrotal exploration. Bilateral ductal obstructions were found in 3 of 9 men without vasal efflux on both sides. The cause of obstruction included spermatocele, chronic epididymal inflammation. In epididymal histology the cause of obstruction was the interstitial sperm granulomas resulting from the rupture of the epididymal duct and chronic epididymitis. We concluded that epididymal exploration is necessary in case with no sperm from testicular end of the vas on both sides.
