Anatomical terminology

The spermatic cord is the name given to the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that run from the deep inguinal ring down to each testicle. This includes its serosal covering, the vaginal tunic as it is an extension of the peritoneum passing through this slit in the trasversalis fascia.

Structure[edit]

The spermatic cord is ensheathed in three layers of tissue:

Function[edit]

Contents[edit]

The pampiniform plexus, testicular artery, artery of the ductus deferens, lymphatic vessels, testicular nerves, and ductus deferens all run deep to the internal spermatic fascia.[1] The genital branch of the genitofemoral nerve,[1] cremasteric artery, and ilioinguinal nerve all run on the superficial surface of the external spermatic fascia.

Clinical significance[edit]

The spermatic cord is sensitive to torsion, in which the testicle rotates within its sac and blocks its own blood supply. Testicular torsion may result in irreversible damage to the testicle within hours. A collection of serous fluid in the spermatic cord is named 'funiculocele'.

The contents of the abdominal cavity may protrude into the inguinal canal, producing an indirect inguinal hernia.

Varicose veins of the spermatic cord are referred to as varicocele. Though often asymptomatic, about one in four people with varicocele have negatively affected fertility.[2]
