Abstract Following sterilization by vasectomy, men my need future fertility, either due to the loss of a child or a new marriage. Following vasectomy reversal there have been a lot of advances in the field to improve the patency and pregnancy rates, although in the modern era of assisted reproductive technology they are usually not counseled with the ease of sperm retrieval and IVF/ICSI. Here we carried out a systematic analysis using the MeSH terms on the search engine Pubmed, like ‘’vasectomy reversal’’, ’’vasovasostomy’(VV)’, ’’vasoepididymostomy’’(VE), ’’optimizing success’’, ’’different sutures’’ to be used, ’’most modern techniques’’ like robotic assisted VV or VE, Video microscopy, analysis of vasal fluid‘’. We found a total of 1200 articles, out of which we selected 75 articles for this review. No meta-analysis was carried out. Further emphasis has been laid on the training of new urologists to learn this complicated technique so that natural conception can be sought for. Further techniques of some complicated cases are described. Keywords: VV; VE; Vasectomy reversal; IVF/ICSI/Vasal fluid Introduction reversal in length, based on the recent evidence. The advances made recently in surgical technique and Vasectomy reversal is the recommended method how they contribute to this surgery are to be critically of reversing sterilization in men desiring fertility analyzed.
