Early symptoms of testicular inflammation are mainly enlargement of testicles, swelling and pain, redness and warmth at the scrotum. In the early stages of testicular inflammation, there may be painful swelling of the testicle on the diseased side, which is usually accompanied by swelling and heaviness in the scrotum, redness of the scrotal skin, increased scrotal skin temperature, and pain in the perineal area. When the disease develops further, there may also be pus in the testicle, which will fluctuate when pressed, and pus can flow out after rupture. Testiculitis is mainly caused by bacterial infection and other reasons, such as men do not pay attention to the hygiene of the genital organs during sex or have sex too frequently, etc., which may lead to bacterial invasion and cause testicular inflammation.
