Testes and Epididymis

Scrotum

Testes

The spermatic cord runs from the abdomen caudally, through the inguinal canal. The inguinal canal is formed by the deep and superficial inguinal rings.

  • Deep inguinal ring: Opening between the internal abdominal oblique, rectus abdominis, prepubic tendon and inguinal ligament.
  • Superficial inguinal ring: Opening in the external abdominal oblique.


In the horse, the left testicle is usually larger and more caudal than the right testicle. It is also usually suspended more ventrally.
