Abstract
Longitudinal intussusception microsurgical vasoepididymostomy (LIVE) increases the patency rate in men with epididymal obstructive azoospermia (EOA). Here, we retrospectively analyzed the early outcomes of our modified single-armed suture technique for LIVE in men with EOA. From February 2012 to November 2013, 51 men received the modified technique and 39 men provided at least one post-operative semen sample. The mean age was 31.4 years old for the men and 29.2 years old for their female partners. The mean duration of obstruction was 34.3 months. Patency was noted in 24 (61.5%) men and pregnancy was reported in 15 (38.5%) female partners. Motile spermatozoa in the epididymal fluid were observed intraoperatively in 14 (58.3%) patent men and 3 (20%) non-patent men, respectively (p < 0.05). In the patent cohort, the mean ages of the pregnant and non-pregnant female partners were 26.5 and 32.7 years old, respectively (p < 0.05). Our modified technique resulted in favorable patency and pregnancy rates in this study. Sperm motility in epididymal fluid and female partner age were important factors associated with the patency and pregnancy rates.
