When the cord twists, blood can’t get in or out.

What you’re seeing:

Left side: A normal testicle with a straight spermatic cord and normal blood flow.

Right side (with the arrow): A twisted spermatic cord. The cord has rotated on itself, cutting off blood supply to the testicle.

Why this is dangerous:

When the cord twists, blood can’t get in or out.

The testicle quickly becomes swollen, dark, and painful due to lack of oxygen.


That’s why the image says “6 hours to save the testicle” — after ~6 hours, permanent damage or loss becomes much more likely.

Key symptoms (real-life warning signs):

Sudden, severe pain in one testicle

Swelling or color change (red, purple, dark)

Nausea or vomiting

One testicle sitting higher than the other

Critical takeaway 🚨 If someone suspects testicular torsion, they must go to the ER immediately. This is not something to “wait and see.”
