When scrotal dampness occurs, patients often feel sweaty and uncomfortable in the scrotum. The perineum is in a humid environment for a long time, and bacteria are easy to breed, which can easily lead to scrotal dermatitis, balanitis, etc. Due to the temperature rise of the scrotum, the testicular spermatogenic ability and sperm maturity are affected, resulting in a decrease in the number of sperm and sperm activity rate, and even sperm abnormalities. The specific situation needs to come to the hospital to see a doctor, inquire about the disease in detail, and have a comprehensive physical examination. Routine examination of urine and prostate massage, and imaging examination can be of great significance for diagnosis and treatment. Pay attention to local cleanness and dryness in life, especially wear loose cotton underwear, and refuse to wear polyester tight briefs. The diet should be light and eat less raw, cold, spicy and stimulating food. For a long-term sedentary working environment, you should get up and move in time, actively change your lifestyle, and suit the remedy to the case. If you have a history of scrotal pruritus, you should actively treat it. If you cut off your clothes, scratch excessively or scald with hot water.
