Results of vasovasostomy or vasoepididymostomy after failed percutaneous epididymal sperm aspirations.

Abstract

After undergoing vasectomy approximately 4% to 6% of men change their minds and desire more children. In the past they had 2 options: 1) vasectomy reversal and 2) sperm retrieval and intracytoplasmic sperm injection. However, in our practices we began to receive requests for another option: reconstructive microsurgery after failed percutaneous epididymal sperm aspiration. In this report we combined our collective experience with 8 patients who requested reconstructive microsurgery after failed percutaneous epididymal sperm aspiration and intracytoplasmic sperm injection. Our intraoperative findings demonstrated minimal trauma to the epididymis resulting from percutaneous epididymal sperm aspiration. At surgery sperm were found in the testicular vas fluid in 10 of 16 vasal units, and vasovasostomy was possible on at least 1 side in 7 of 8 patients. Vasoepididymostomy was possible when needed. Of the 8 couples 4 achieved pregnancy (50%). Vasovasostomy or vasoepididymostomy is possible after percutaneous epididymal sperm aspiration.
