Although parents are extra careful to prevent, but still can not avoid the child injury, this time when the wall accidentally injured the key parts, testicles. Children are naughty and lead to testicular injuries, but testicular injuries in young people are more often caused by direct violence, and this article gives readers some knowledge about the ins and outs of testicular injuries. What is a testicular injury? The testicle is located in the scrotum, because the scrotal skin is loose, the testicle is mobile, and there is a tough white membrane of the testicle itself, so the testicle is not easily injured, and the incidence of injury is lower than that of the penis and scrotum. The common cause of testicular injury is direct violence. The etiology of testicular injuries 1, closed injuries including testicular contusions, testicular torsion, testicular dislocation and spermatic vascular injuries. The causes of injury include crushing injury, kicking injury, car accident injury and brawl injury, etc., causing testicular interstitial capillary hemorrhage foci, rupture of varicocele and testicular swelling. Closed injuries such as straddling injuries and crush injuries can also cause testicular rupture. Testicular dislocation is often due to blunt external forces on the perineum that squeeze the testicle outside the scrotum. The testicle can be squeezed into the inguinal canal, abdominal cavity, prepubic bone, penile root and perineum. Testicular torsion is a rare urological emergency, mostly occurring in adolescents, and may be related to congenital anatomical malformations, such as cryptorchidism, or because the sheath capsule is too wide the testicle is easily rotated, and when the testicle is torsioned it is usually rotated from the outside to the inside, affecting the blood supply to the testicle and producing clinical symptoms due to testicular ischemia. 2, open injuries including gunshot wounds, stab wounds, lacerations and cutting wounds. More common in wartime, often combined with scrotal injury, serious testicular artery injury or testicular tissue crushing injury, and finally lead to testicular atrophy. 3.Medical injury Testicular injury is caused by accidental injury to the spermatic cord vessels during testicular tissue biopsy or surgical operation. How to prevent testicular injury? The main reason for avoiding testicular injury is to avoid trauma. It usually occurs in young adults. Injuries to the testicles, sphincter, spermatic cord and scrotal wall often occur at the same time and should not be subjected to direct violent attacks. Secondly, daily life should pay attention to the maintenance of the testicles: (1) middle-aged men should pay attention to the maintenance of their testicles. Testicular maintenance is an important means of addressing male dysfunction in men. If you find a different painful feeling during massage, it may be testicular inflammation or epididymitis, please go to the hospital for examination in time. (2) You should eat more fresh vegetables and fruits to increase the intake of vitamin c and other ingredients to improve the body’s anti-inflammatory ability. (3) Pay attention not to eat spicy and stimulating food, not to smoke and drink, not to stand and sit for a long time, not to have excessive sexual life, not to masturbate frequently, etc. (4) Male friends should pay attention to their daily sleeping position, it is best to lie on your back is better, this is conducive to testicular safety, but also conducive to sleep. The testicles themselves will not twist, but there is a rope like a sperm cord above the testicles will twist and “knot”. As the blood vessels that supply nutrients to the testicles and carry away metabolic waste pass through the sperm cord, once the sperm cord is “knotted”, the testicles will be “starved” and will generally be ischemic and necrotic after more than 12 hours. Therefore, men should pay attention to this problem.
