Abstract
Three young men with impotence due to a pudendal arteriovenous malformation had a common selective pudendal arteriographic finding of early passage of contrast medium from the bulbar artery region into the venous drainage of the pelvis. Perineal exploration revealed the malformation and correction resulted in significant restoration of erectile capacity. This entity may be a frequent occurrence in young men that may become apparent only when trauma or disease affects the contralateral pudendal artery or its branches.
