Testicular torsion

Overview

When the testicle rotates (testicular torsion), it twists the cord supplying blood to the loose bag of skin (scrotum) beneath the penis. This may occur after vigorous activity, a minor injury to the testicles, or sleep.

Symptoms

Sudden, severe pain and swelling in the testicle are symptoms.

Treatments

Surgery is required. Treated promptly, the testicle can often be saved. A longer wait may affect the ability to father children.
