  • Title: Effect of vasovasostomy on contralateral testicular damage associated with unilateral vasectomy in mature and immature Lewis rats.
    Author: West DA, Chehval MJ, Winkelmann T, Martin SA.
    Journal: Fertil Steril; 2000 Feb; 73(2):238-41. PubMed ID: 10685521.
    Abstract:
    OBJECTIVE: We sought to determine if laser-assisted vasovasostomy could reverse the contralateral histologic testicular changes associated with unilateral vasectomy. DESIGN: A prospective, randomized, blinded, controlled study. SETTING: Animal microsurgical laboratory, St. John's Mercy Medical Center, St. Louis, Missouri. PATIENT(S): Twenty mature and 20 immature male Lewis rats. INTERVENTION(S): Ten mature and 10 immature male Lewis rats underwent unilateral vasectomy. At 5 months, testicular biopsy and laser-assisted vasovasostomies were performed followed 2 months later by evaluation of vas patency and repeat testicular biopsy. Control animals consisted of 10 rats in each group, 5 that underwent sham operations and 5 that had halothane anesthesia alone. RESULT(S): In the immature and mature groups unilateral vasectomy resulted in marked contralateral testicular damage in 30% (3 of 10) and 50% (5 of 10), respectively. Vas patency determined 2 months after vasovasostomy was 80% (8 of 10) in the mature group and 89% (8 of 9) in the immature group. No animal that had contralateral testicular changes after vasectomy and a patent vas after vasovasostomy showed improvement in testicular histology. CONCLUSION(S): It appears that contralateral testicular damage associated with unilateral vasectomy is not improved 2 months after successful vasovasostomy in mature or immature Lewis rats.
