technique for EV, the availability of EV (either due to training or
practice pattern), the lower patency, and the lower pregnancy
we did not include EV patients in this analysis. We wanted this
to be a homogenous population of patients who underwent only
VV, which is the more widely available technique and more com-
monly performed. Hence we excluded patients who underwent
even a unilateral VE.
We have performed a retrospective review of VV outcomes.
There was a higher patency associated with the presence of sper-
matozoa in the vasal Fuid compared to the absence of spermato-
zoa. Information from this study will aid patient counseling on
outcomes after VV.

Microscopic visualization of whole spermatozoa or sperm
parts in the vasal Fuid at the time of VV is positively associated
with postoperative patency.
