Another thing that needs to be emphasized is urological diseases, such as chronic prostatitis will appear scrotal dampness, coolness, and there will be urinary discomfort symptoms such as urinary urgency and frequency, which can be ruled out through the examination of prostate fluid. Patients with varicocele will also have dampness in the scrotum area, and patients will find earthworm-like blood vessels in the scrotum area, which can be treated by laparoscopic varicocele ligation.
