Obstructive azoospermia after a second renal transplant: an avoidable cause of infertility.

A case of obstructive azoospermia and infertility after renal transplantation is presented. Vasectomies were performed incidental to insertion of a renal allograft on each side and were not amenable to vasovasostomy owing to retraction of the proximal vasal stump. The desirability of spermatic cord preservation in younger men undergoing renal transplantation is discussed.
