Epididymal obstruction is one of the most common etiologies of infertile men with obstructive azoospermia. Microsurgical vasoepididymostomy (MVE) is the procedure of choice for infertile men with epididymal obstruction who desire to achieve natural pregnancy. There are several techniques on how to perform MVE. Among the several techniques, longitudinal intussusception vasoepididymostomy (LIVE) is preferred by the surgeons. LIVE oers the highest patency and pregnancy rates compared to the other techniques. The principles of a successful anastomosis include the use of appropriate microsurgical instruments, mucosa-to-mucosa apposition, tension-free and watertight reconstruction and preservation of blood supply. LIVE is a technically challenging procedures. Meticulous microsurgical steps are warranted in order to arrive with a good reproductive outcomes.
