There is no positive correlation between the three degrees of varicocele and clinical symptoms. Patients may experience scrotal swelling, testicular atrophy and localized swelling. 1. Scrotal swelling: some patients with varicocele may experience scrotal swelling, and in severe cases, patients may also experience generalized discomfort, fever and other symptoms. 2. Testicular atrophy: If the patient suffers from varicocele, it may affect the level of sex hormone secretion, which may lead to abnormal testicular development and testicular atrophy. 3. Localized swelling: If the patient suffers from varicocele, after standing for a long time or strenuous exercise, a large amount of venous blood will be in the trapezoidal vascular plexus, which may lead to the patient’s localized swelling. If the patient has varicocele, he should go to the regular hospital for examination in time and be treated under the guidance of the doctor.
