The testicular (gonadal) artery is a paired vessel arising directly from the abdominal aorta at the level of the second lumbar vertebra, descending retroperitoneally and traversing the inguinal canal within the spermatic cord to supply the testis. During inguinal hernia repair the artery must be identified and preserved alongside the vas deferens — inadvertent ligation or transection risks testicular ischaemia and atrophy, particularly in pediatric patients with smaller-calibre vessels. Simulators for pediatric laparoscopic inguinal hernia repair commonly represent the testicular artery using a coloured elastic loop or "scoubidou" lanyard placed alongside a contrasting-colour loop representing the vas deferens. The colour contrast supports the training output of vessel-vs-duct discrimination during simulated dissection.
