I feel a lump inside my testicles.

When people take a shower, they may find a pimple in their testicles. Some people don't pay attention to it, thinking it is a small matter that will disappear in a few days. In fact, it is not the case. If you find a pimple in your testicles, you need to be very careful, because it may be the early stage of testicular cancer. Of course, if it does not continue to grow, it is not a big deal.

If a man has a urinary tract infection and does not receive timely treatment, the bacteria will invade the epididymis along the vas deferens, causing epididymitis. The entire scrotum will have a series of inflammatory reactions, sensitivity to touch, and a burning sensation when urinating. These are manifestations of epididymitis and require prompt medical attention.

2. Orchitis

Orchitis is often an extension of epididymitis. Bacteria are still the "culprit" of adult diseases, but children's orchitis is different, and is more often caused by the mumps virus. The symptoms of orchitis are enlarged testicles, pain when pressed, and red, swollen, hot and painful scrotal skin. If this disease is not treated in time, it will affect fertility.

The testicles have abundant blood flow, so they are prone to bruising and swelling when injured by sexual activity, vigorous exercise, or violence. If the injury is severe, the testicles may even become necrotic and cause sexual dysfunction. How to check for testicular edema? A flashlight is the best tool. If the light cannot penetrate the scrotum, it indicates testicular bruising.

5. Testicular rupture

The testicles are located in a relatively superficial position and are not protected by protective gear. They have been vulnerable to attack since ancient times. A violent punch is enough to smash the testicles into pieces, accompanied by severe pain in the testicles. Men will suddenly faint, sweat, feel nauseous, and dizzy. If the spermatic artery is severed or ruptured, it will be difficult to repair it.
