There are more reasons for scrotal itching in men, and the common ones are as follows: 1. Underwear and underwear are worn uncomfortably, and the material appears to be correspondingly irritating, causing local itching, requiring replacement of underwear and underwear; 2. Patients with genitourinary system-related diseases, such as prostatitis and vesiculitis, are also prone to scrotal dampness and itching; 3. Bacterial and fungal infections of the scrotal skin appear, requiring selection of sensitive antibiotics for treatment; 4, the presence of allergic factors, due to the presence of certain allergens, resulting in itching, flaking, redness and swelling of the scrotum, etc. It is necessary to remove the allergens and then choose anti-allergy drugs for treatment. In either case, it is recommended to go to the local regular hospital for examination and treatment.
