Spermatic cord
The testicular duct and vessels share an inguinal route
High-yield
External spermatic fascia derives from external oblique, the cremasteric layer chiefly from internal oblique, and internal spermatic fascia from transversalis fascia. Transversus abdominis arches above without adding a corresponding covering.
Overview
The spermatic cord carries the ductus deferens, blood vessels, lymphatics and nerves between the abdomen and testis. Beginning at the deep inguinal ring, it crosses the inguinal canal and continues into the scrotum. Three coverings surround the bundle, each reflecting part of its passage through the abdominal wall.
Reference facts
- Boundaries
- From the deep ring lateral to the inferior epigastric vessels, it passes through the canal and superficial ring toward the posterior testis, enclosed by three spermatic layers.
- Contents
- The bundle contains the ductus deferens, testicular, cremasteric and deferential arteries, pampiniform veins, lymphatics and autonomic fibers, plus the genital branch of the genitofemoral nerve. A processus vaginalis remnant may accompany them.
- Communications
- The inguinal course links abdominal extraperitoneal tissue to scrotal coverings. A persistent processus vaginalis provides a separate peritoneal passage that may carry fluid or a hernia.
Mnemonic
A duct with its traffic: arteries in, veins and lymph out, nerves alongside. Keep the ilioinguinal nerve beside the cord rather than counting it as a true cord content.
Clinical correlation
Cord twisting can restrict venous drainage and then arterial perfusion, producing congestion and ischemia in testicular torsion. An indirect inguinal hernia follows the deep ring alongside cord structures and may continue into the scrotum within the spermatic coverings.
