Ge. Lemack et M. Goldstein, PRESENCE OF SPERM IN THE PRE-VASECTOMY REVERSAL SEMEN ANALYSIS - INCIDENCE AND IMPLICATIONS, The Journal of urology, 155(1), 1996, pp. 167-169
Purpose: We determined the incidence of sperm in the ejaculate before
vasectomy reversal, and correlated this result with intraoperative and
postoperative findings. Materials and Methods: Before vasectomy rever
sal semen was analyzed and granulomas were palpated in 186 men. The re
sults were correlated with intraoperative vasal fluid and postoperativ
e semen analyses. Results: Of 18 men (9.7%) with sperm present in the
pre-reversal analysis 94% had sperm in at least 1 vas intraoperatively
. The presence of palpable granulomas at the vasectomy site did not co
rrelate with either pre-reversal or post-reversal semen analyses, or t
he presence of sperm in the vasal fluid intraoperatively. Conclusions:
Sperm are present in 9.7% of pre-reversal ejaculates and predict sper
m in at least 1 vas intraoperatively. These findings also suggest the
possibility of late vasectomy failures.
