Factors and practice patterns that affect the decision for vasoepididymostomy

To determine the factors used to make the decision between vasovasostomy (VV) and vasoepididymostomy (VE) by leaders performing microsurgical vasectomy reversal using a questionnaire.

An online questionnaire was sent to all members of the Society for the Study of Male Reproduction (SSMR), a male reproduction subspecialty society of the AUA, using the SurveyMonkey platform.

Sixty-seven surgeons responded to the questionnaire (27% of SSMR members). Of which 72% of members performed less than 50 vasectomy reversals per year. Also, 71% of members stated that less than 20% of their vasectomy reversals are vasoepididymostomies. When evaluating epididymal fluid at the time of reversal, 87% would perform a VE for pasty fluid, 66% with creamy fluid without sperm heads and 55% with no or scant fluid. With respect to banking sperm, 36% take sperm or testicular tissue at the time of VE while 37% sometimes take sperm mostly depending on the couple's preference. The Berger end-to-side with intussusception VE technique is used by the majority of members (78%). The presence of intact sperm or sperm parts determined the location in the epididymis for anastomosis for 55% and 19% of members respectively. Postoperative semen testing after a VE is evaluated first between 6 weeks to 3 months for 64%. The procedure is considered a failure between 6 to 12 months for 34% and 12 to 18 months for another 48% if no sperm is seen on semen analysis.

Most members perform a VE with pasty fluid or creamy fluid without sperm heads. Three out of four members are using the Berger end-to-side intussusception technique to perform their VE. More studies are needed to determine the optimal circumstances to perform a VE as there is significant variation in responses even among members of the SSMR.
