TESTICULAR TORSION CAUSES

Some testes hang in such a way that they twist more easily than others. Nearly all torsions happen to adolescent males--between the ages of 12 and 18--because their testes enlarge by a factor of five to six during puberty. A larger testis is more likely to twist. Torsion can also occur in a newborn.

Symptoms of testicular torsion are sudden severe pain in the scrotum, swelling, nausea and vomiting.
