A man's testicle receives its blood supply through a structure called the spermatic cord. This cord can become twisted, cutting off blood to the testicle. This is known as torsion of the testicle.

What is going on in the body?

In some men, the tissue surrounding the testicle is not well attached to the scrotum. This makes it easy for the testicle to become twisted around the spermatic cord. If not treated, the tissue of the testicle may die. This problem is more common at puberty. This is because the testicles grow to 5 or 6 times their previous size during this period.

What are the causes and risks of the condition?

Torsion of one testicle may indicate that a man is at higher risk for the same condition on the other side. This is because the defect that makes it possible for the testicle to twist is often present on both sides. This condition can sometimes be due to testicular cancer that causes the testicle to increase dramatically in size.
