Can you die from testicular torsion?
Testicular torsion is a medical emergency. Since all blood for the testicle comes through the spermatic cord, the blood supply is cut off with a twist. The testicle will shrink ("atrophy") if the blood supply isn't restored within 6 hours. With no blood, the testicle could die (or "infarct").
How long can you go with a twisted testicle?
If testicular torsion goes on for more than a few hours, it can permanently damage the testicle, and a damaged testicle must be removed. The amount of twisting can be anywhere from 180-720 degrees. The degree of twisting affects how quickly a testicle gets damaged.
