Microsurgical reconstruction is a common technique used in the treatment of EOA. In the present study, we analyzed the effectiveness of microsurgical vasoepididymostomy (MVE) at different levels and compared the differences among several MVE techniques.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>A literature search was conducted in the PubMed, Web of Science, and Embase databases, according to the Preferred Reporting Items for Systematic Reviews and Meta\u2010Analyses guidelines.
