The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower thoracic and upper lumbar region and migrates into the scrotum. During its descent it carries along with it the vas deferens, its vessels, nerves etc. There is one on each side.

Structure

The spermatic cord is ensheathed in three layers of tissue:

  • external spermatic fascia, an extension of the innominate fascia that overlies the aponeurosis of the external oblique muscle.
  • cremasteric muscle and fascia, formed from a continuation of the internal oblique muscle and its fascia. It is located behind the tunica vaginalis.
