Testicular torsion happens when the spermatic cord rotates and becomes twisted. Some men are born with a higher risk for the condition. Torsion of the testes can occur after an injury to the groin, but also due to rapid growth during puberty.
Males who practice contact sports may also experience testicular torsion. In fact, it is during contact sports when blunt, penetrating, or degloving lesions can occur, which can cause male infertility.
Since testicular torsion causes the blood flow to the testes to stop, spermatogenesis is interrupted within 4 to 6 hours due to a lack of blood flow.
