After 12\u00a0weeks, functional patency was functionally assessed by evaluating for motile spermatozoa distal to the anastomosis. If no motile spermatozoa were visible, the mechanical patency of the anastomosis was tested by the ability of methylene blue to pass through the surgical anastomosis. The key procedure in Guo's SA\u2010LIVE was cutting each needle with over 1cm attaching suture and making a flat overhand bend knot to tie the needle to the other end of the suture, after the needles were passed through the epididymal tubule and then the vasal lumen in an inside\u2010out fashion, and then, the needles were passed through the vasal lumen in an inside\u2010out fashion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The proportions of functional patency were 50.0% (3\/6), 33.3% (2\/6), and 50% (3\/6) for the DA\u2010LIVE, SA\u2010LIVE, and Guo's SA\u2010LIVE groups, respectively (<jats:italic>P<\/jats:italic>\u00a0=\u00a0.799).
