The testicles are a very important sexual organ for men and play an important role in the development and maturation of the male reproductive organs and in the presentation of male secondary sexual characteristics. There are many causes of testicular pain in men, such as orchitis, testicular torsion, testicular destruction, testicular ischemia, and many others. The most common cause of testicular pain in men is orchitis, which is caused by bacteria, viruses and other pathogenic bacteria that infect the testicles and cause swelling and pain, gonorrhea, which is not treated in time, can cause orchitis, and chronic prostatitis, which can also cause pain in the testicles. Torsion of the testicle is one of the common emergencies in the male scrotum, usually caused by violent exercise or trauma, which can cause severe pain in the testicle, usually occurring suddenly during sleep or tranquility. The testicles have more room to move in the scrotum and are maintained by a tough white membrane, so the chances of a closed injury are very small. Most testicular disfigurement is related to violence, car accidents, etc. After the injury, the testicle will be in severe pain with nausea, and in severe cases, fainting or shock will occur. Testicular ischemic pain is caused by testicular atherosclerosis, and is also part of the display of systemic vascular lesions, commonly seen in the elderly. Men with egg pain should pay attention to the situation, rule out the possibility of sending lesions to the testicles, identify the specific cause of the disease after timely treatment to avoid more serious consequences.
