Varicocele is a common and frequent disease among young and strong men, with an incidence of about 10-15% of adult men, of which, about 80% are fertile and only about 20 are combined with infertility. Varicocele that can give birth normally is considered physiological and does not need treatment; varicocele combined with definite infertility is the indication for treatment. Usually the clinical examination reveals varicose spermatozoa combined with definite male infertility, and after excluding the female cause of infertility and other factors that cause infertility, the semen routine semen quality is obviously abnormal, then there is an indication for surgical treatment of varicose spermatozoa. Before treatment, a detailed physical examination, ultrasound of the spermatic veins and endocrine hormone tests should be performed to systematically assess the degree of varicocele, the severity of the impact on fertility, the benefits that surgical treatment may bring to the improvement of reproductive function and the possibility of possible complications. Since semen quality still does not improve significantly in 10-30% of infertility patients after varicocele surgery, patients whose semen quality is not very poor can be treated with conservative medication for a period of time, and if semen quality improves significantly or even if the wife conceives successfully through treatment, there is no need for surgery; if semen quality does not improve after systematic and regular treatment or even If the quality of semen does not improve or even progressive damage after systematic formal treatment, surgery can be taken. Some patients with varicocele may have clinical symptoms such as swelling of the scrotum, pain and discomfort in the lower abdomen, which are usually mild in the morning and gradually increase in the afternoon or evening with increased activity. If varicocele is combined with the above mentioned symptoms and affects daily life and work, surgery can also be considered. However, because many of the clinical symptoms of varicocele and chronic prostatitis are concurrent or confused with each other, many patients’ symptoms do not improve or even worsen after surgical treatment. Therefore, it is recommended that patients who are ready for surgical treatment just because of their symptoms try to use conservative medication first, and then consider surgical treatment if the symptoms are not satisfactorily relieved to ensure post-operative efficacy.
