We compared delayed vasectomy reversals performed in rats using fibrin glue combined with 3 transmural sutures or a conventional microsurgical technique. Forty Sprague-Dawley rats underwent bilateral vasectomy followed 2 weeks later by bilateral vasovasostomy using fibrin glue or a conventional microsurgical suture technique. Our protocol evaluated fertility rates after a 3-week mating period, sperm granuloma formation, histological changes at the anastomotic site, longitudinal tensile strength and mean testicular weight. The fibrin glue technique required significantly reduced operative time (p <0.0005) and showed statistically lower tensile strength performance (p <0.0005). All other parameters showed no statistical difference between the two techniques. Fibrin-glued vasovasostomy is efficient in a delayed protocol and deserves further clinical experience.
