The Utility Of Sperm Cryopreservation At The Time Of Vasectomy Reversal

Purpose: We retrospectively evaluated the utility of sperm cryopreservation at the time of vasectomy reversal.Materials and Methods: From April 2016 through December 2018 a total of 26 men underwent vasectomy reversal. Sperm cryopreservation is routinely offered at the time of vasectomy reversal at our institution. We sought to assess utilization of cryopreserved sperm by those men with early or late vasectomy reversal failure.Results: Of 26 patients presenting for vasectomy reversal 22 (85%) elected to cryo-preserve sperm. Sperm were obtained for freezing from the vasal (7 patients) or epididymal fluid (3), or via testicular biopsy (12). Three patients were lost to followup postoperatively. Of the 23 who presented for post-procedure followup 19 either had semen analyses with motile sperm or a live birth (83% success rate). There were 4 early failures and 2 late failures; all patients with failures had elected to cryopreserve sperm at the time of initial reversal. Three of the 6 individuals (50%) with vasectomy reversal failure elected to use cryopreserved sperm for in vitro fertilization/intracytoplasmic sperm injection, with 2 of these (67%) resulting in live births.Conclusions: Of those patients who experienced vasectomy reversal failure 50% elected to use cryopreserved sperm that had been procured at the time of initial reversal. Given the potential for early or late failure, cryopreservation of sperm at the time of vasectomy reversal should be routinely offered as a means of avoiding the added expense and potential morbidity of future surgical sperm retrieval.
