Testicular torsion is the twisting of the spermatic cord, which supports the testicles in the scrotum. When this happens, the blood supply to the testicle and surrounding tissues is cut off. The testes are the glands that make sperm. They are ovoid in shape and are located in the scrotal bag.
The blood supply to the testicles comes from the spermatic arteries that arrive through the spermatic cord. On the other hand, venous drainage takes place through the spermatic veins that follow the same path, but in the opposite direction.
When testicular torsion occurs, there is an obstruction of the blood vessels, which leads to a lack of blood flow to the testicle that, if prolonged, can lead to loss of the testicle.
