The testicles are the oval-shaped pair of organs that sit in the sac below a man's penis. The testicles make sperm. Sperm are stored in the epididymis, which is a coiled tube on top of each testicle. The epididymis is connected to the spermatic cord. The spermatic cord carries sperm from the epididymis into the body and contains many blood vessels and nerves.
Testicular torsion is when the spermatic cord above your testicle twists, cutting off blood flow to your testicle.
See a doctor right away if you think you have testicular torsion. It's a medical emergency.
Doctors may try to untwist the testicle by turning it by hand. If this works, your doctor will do surgery later to keep the testicle from twisting again. If it doesn’t work, your doctor will do surgery right away to untwist the testicle. During surgery, your doctor will sew both testicles so that they can't twist again.
