Within the scrotum, the testicles are secured at either end by a structure called the spermatic cord. Sometimes, this cord gets twisted around a testicle, cutting off the blood supply. Symptoms of testicular torsion include sudden and severe pain, enlargement of the affected testicle, tenderness, and swelling.
This condition, which occurs most often in young males less than 25 years of age, can result from an injury to the testicles or from strenuous activity. It also can occur for no apparent reason.

Testicular torsion requires immediate medical attention. Treatment usually involves correction of the problem through surgery. Testicular function may be saved if the condition is diagnosed and corrected immediately. If the blood supply to the testicle is cut off for a long period of time, the testicle can become permanently damaged and may need to be removed.
