    For men, if the testicles swell, they must understand the specific reasons. The most common cause is testicular torsion or damage. Some men have longer mesentery and are prone to testicular sprain. In addition, if a man has varicocele, this is also an important cause of testicular swelling, and its harm is also relatively large. Let's take a look at this aspect.

    What's wrong with a man's swollen balls?

    Testicular swelling and pain can also cause testicular disease due to trauma, inflammation, tumors, etc. Testicular disease often affects the normal functioning of important reproductive organs. It can lead to male infertility, so testicular swelling and pain should be sought out promptly. If treatment is delayed, it is likely to cause pain in the body and in the heart.

    Common causes of testicular swelling and pain

    1. Testicular torsion.

    Testicular torsion is one of the common emergencies in the scrotum. Generally, there is strenuous activity a few hours before the onset, or the testicles have been subjected to external force. Severe pain in the testicles occurs suddenly during sleep or quietness. This is the first symptom of the disease and one of the main diagnostic criteria. Some patients are accompanied by nausea and vomiting, scrotal swelling, and obvious tenderness.

    2. Testicular damage.

    The testicles are more mobile in the scrotum and are protected by a tough albuginea, so the chance of closed injury is small. Testicular injuries are mostly related to violence, car accidents, etc. After the injury, the testicles suffer severe pain accompanied by nausea, vomiting, and even fainting or shock. During physical examination, testicular swelling, unclear outline, or scrotal congestion, and obvious tenderness, B-ultrasound and CT are not only helpful in the diagnosis of this disease, but also can clarify the location and scope of testicular damage.

    3. Testicular ischemic pain.

    Testicular ischemic pain is more common in the elderly. The pain is severe, aggravated by activity, and relieved by rest. Prostatic fluid microscopy is normal. It is often due to arterial stenosis caused by testicular arteriosclerosis. Testicular atherosclerosis is often a local manifestation of systemic vascular disease, and is mostly unilateral, with the left side being more common than the right side.

    4. Orchitis.

    The testicles are located in the scrotum, one on each side. The testicles secrete male hormones and play an important role in the development and maturity of male reproductive organs and the emergence of male secondary sexual characteristics. There are many causes of orchitis. For example, patients with mumps may be complicated by orchitis, causing testicular pain and swelling; gonorrhea is currently the sexually transmitted disease with the highest incidence rate, and can cause orchitis in severe cases; chronic prostatitis can also cause testicular pain, which is manifested as unilateral pain, mostly dull pain or stretching pain, and is persistent. The patients are mostly young adults and rarely in the elderly.
