Inguinal canal
60
What is the spermatic cord formed of?
A collection of vessels, nerves and ducts
61
What is spermatic fascia?
Layers of the anterior abdominal wall that surround the spermatic cord because of the descent of the testes

How can you diagnose testicular torsion?
From the presenting symptoms or an ultrasound if the diagnosis is unclear
