The prevalence of varicocele (VC) in adult men is 11.7%, and 25.4% in men with abnormal semen quality. VC is the most common male disorder and is often characterized by impaired ipsilateral testicular growth and development with pain and discomfort, low fertility and hypogonadism. Among the many causes of male infertility, VC is the focus of clinical research. In some men, VC is associated with progressive testicular damage during puberty and leads to infertility. The clinical classification of varicocele includes: Subclinical: varicocele is not palpated or observed during the lying down or Valsava examination. However, a specialist examination (Doppler ultrasonography) can detect varicocele: Grade 1: varicocele can be palpated on Valsava but not otherwise detected; Grade 2: varicocele can be palpated but not observed when lying down; Grade 3: varicocele can be palpated and observed when lying down. Ultrasound images of varicoceles (see ultrasound report below): Spermatic veins can be diagnosed as tortuous and dilated with an extension of more than 0.2 cm, if they are more than 0.3 cm, they are considered to be severely varicose and need to be graded in combination with clinical examination. It is necessary to combine the patient’s condition and develop a more suitable treatment plan according to individual differences. If the varicose extension is less than 0.2 cm, it will not be diagnosed, and if the varicose does not affect sperm quality and the patient does not have any uncomfortable symptoms, no treatment is needed. In short, varicocele is the most common disease in male medicine and does not require treatment if the varicocele does not affect sperm quality and the patient does not have any discomfort. Severe varicoceles are recommended to be treated, whether surgery or medication varies from person to person, and cannot be over-treated by asking patients to undergo surgery in a uniform manner, which increases the burden of patients.
