The authors conducted this research to evaluate the results of microsurgical vasoepididymostomy for obstructive azoospermia from which to draw the initial exoenenced lessons about technique of microsurgical reconstruction of seminal tract at Hanoi medical university. Using statistical methods to describe the data of 16 eligble patients, they obtained the following results: history of sexually transmitted infection and a history of PESA or TESA were seen in 6/16 patients. 16 patients with a total of 26 reconstrcuted sides (10 patients with two sides, 5 patients with one side) have achieved a patency rate of 6/15 patients, an ICSI rate of 7/15 patients and overall pregnancy rates of 7/16 patients (including
2 patients achieved by natural means and 5 achieved by ICSI from frozen sperm soon after the operation). The live birth rate was 6/7 of patients.
