May also be called: Testis Torsion

Testicular torsion is when the spermatic cord, which provides blood flow to the testicle, rotates and gets twisted. The twisting cuts off the testicle’s blood supply and causes sudden pain and swelling. Some people have nausea and vomiting.

More to Know

Testicular torsion is often related to a genetic condition called bell clapper deformity. In this condition, testicles can twist more easily because they’re not attached normally to the scrotum.

Testicular torsion happens most often in teenage boys. To fix it, surgeons make a small cut in the scrotum, untwist the spermatic cord, and stitch both testicles to the scrotum to prevent future twisting.

Keep in Mind

Testicular torsion is a medical emergency that must be treated right away. Boys need to know that genital pain is serious and shouldn’t be ignored. Ignoring pain for too long or hoping it goes away can lead to severe damage to the testicle and even its removal.
