The anastomosis and vasectomy sites were inspected for sperm granuloma. Patency was confirmed by injecting Methylene blue from the abdominal end of the vas through the anastomoses to epididymis. Results: In the standard double-armed longitudinal intussusception VE, the single-armed and reverse singlearmed longitudinal intussusception VE groups the patency rate was 100%, 75%, 87.5%, sperm granuloma rate was 12.5%, 25%, 25%, the average operation time was 38.1±4.3, 42.3±2.9, 41.0±3.3 min. Conclusions: Bilateral vasectomy (closed epididymis) is reliable, simple method to make OA animal model for performing microscopic VE training. The results of our study have shown that the single-armed suture technique to perform VE is almost as effective as the double-armed technique and can save operation cost. This allows the use of single-armed sutures to perform microsurgical VE, in which double-armed sutures are not available. Reverse single-armed longitudinal intussusception VE can reduce the probability of back-walling the tubular lumen.
