title: Microscopic vasovasostomy and spermatogenesis.
abstract: Initial clinical experience with a new microscopic 2-layer anastomosis for vasovasostomy shows that normal patency can be achieved almost every time. Histologic and electron microscopic studies on initial specimens and subsequent ejaculates indicate that stricture is a common cause of failure with conventional vasovasostomy techniques, obstruction of the vas deferens inhibits spermatogenesis and relief of obstruction allows return of spermatogenesis in the vast majority of cases.
