What Is Testicular Torsion? Within the scrotum, the testicles are secured by a structure called the spermatic cord, which contains an anchoring tissue called the gubernaculum at the lower part of the testicle. 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 males who are under age 25, is usually due to the congenital absence of the gubernaculum, which would otherwise keep the testicle from twisting on the spermatic cord.
