The Kinetics of Sperm Return and Late Failure Following Vasovasostomy or Vasoepididymostomy: A Systematic Review

Vasovasostomy (VV) and vasoepididymostomy (VE) are technically challenging microsurgical reconstructive procedures necessary for men with obstructive azoospermia at the level of the vas deferens or epididymis. Patency rates following VV or VE have been widely described in the literature. However, few reports have discussed the timing of sperm return to the ejaculate following reconstruction as well as the proportion of men that develop late failure following VV or VE. Therefore, the objective of this article is to review the rates and predictors associated with late failures and the timing of sperm returning to the ejaculate following VV and VE.
