Patency Following Microsurgical Vasoepididymostomy and Vasovasostomy: Temporal Considerations

Abstract

Patency is rapid following vasovasostomy but requires 12 or more months following vasoepididymostomy. Intervention for azoospermia is appropriate 6 months after vasovasostomy and 1 year after vasoepididymostomy. Intraoperative cryopreservation of sperm in men undergoing vasoepididymostomy and postoperatively in all men with motile sperm will maximize fertility options.
