Clinical use of carbon dioxide (CO2) laser in microsurgical vasovasostomy.

Herein are reported the first 4 clinical cases of carbon dioxide (CO2) laser microsurgical vasovasostomy. Fusion-coagulation of the vas wall was successfully accomplished, as demonstrated by adequate postoperative sperm counts and a 50 per cent pregnancy rate. A significant reduction in the total operative time was achieved as compared with the conventional microsurgical suture technique, corroborating the ability of the CO2 laser to simplify this technique while producing a sperm-tight anastomosis.
