Identification of motile sperm in caput epididymis. Intraoperative observations and clinical correlations

This retrospective review of patients who underwent vasoepididymostomy demonstrates that motile sperm may be identified in the most proximal portion of the epididymis, and implies that induction of sperm motility may be independent of transit through the epididymis. Although further studies are needed, the data imply that it may not be necessary to identify motile sperm in the epididymal fluid to achieve a successful vasoepididymostomy.
