Torsion of testis or testicular torsion

It is a condition in which the testicle rotates on the spermatic cord which supplies blood for the testicles. This result in block of blood supply to testicles causing sever pain and swelling. It is common in males of age group under 25.

In the fetus the testicle develops within the abdomen and migrates down into the scrotum, trailing its blood supply behind it like a leash. In the scrotum the testicle resides within a smooth sack called the tunica vaginalis. The testicle can spin and move about within the sack. As males grow and age the testicle develops connections with the sack making it harder for the testicle to spin or twist. This is why torsion is usually seen in younger men, adolescents, and children.


It can occur during fetal development leading to neonatal torsion or vanishing testis and is one of the main cause for monarchism (single testicle).

It needs emergency treatment to save the testicles. Other wise it can lead to permanent damage to the testicles leading  to necrosis of testis and atrophy of testis. It can lead to sterility
