Testicular torsion is an extremely painful condition and a medical emergency. Males have two testicles held within the scrotum, which are supplied with blood via the spermatic cord. This cord can become twisted, cutting off the blood supply to the testicle. In addition to pain, testicular torsion poses a severe risk to the testicle. Prompt medical treatment can help resume normal blood flow and testicle position.
The vast majority of men and boys who develop testicular torsion already have a condition called bell clapper deformity, although they may not be aware of this until the torsion occurs. In normal anatomy, the testicles are attached firmly to the inside of the scrotum with connective tissue. This prevents them from moving around. People with bell clapper deformity have weaker connective tissue between the testicles and the scrotum, or none at all. As such, the testicles have more freedom of movement within the scrotum, making them more likely to become twisted.
