Clinically, the occurrence of testicular torsion is unilateral. If one testicular torsion leads to resection due to prolonged ischemia, fertility can be guaranteed as long as the opposite testicle is ensured to be normal. Therefore, in the event of testicular torsion, patients who undergo unilateral orchiectomy should have their semen routinely retested more than six months after surgery. If the quality and quantity of sperm are at normal levels, there is no effect on fertility. Testicular torsion mainly occurs in adolescents and tends to occur at night. Therefore, if adolescents experience severe pain in the lower abdomen of the scrotal area at night, they should go to the hospital promptly for examination to rule out the emergency of testicular torsion. If the testicular torsion is repositioned by manipulation within 12 hours, the blood flow can be restored again with less impact on the testicle. If it is greater than 12 hours or more intraoperatively, or if an ultrasound examination reveals significant ischemia, one testicle will need to be removed.
