Varicoceles have a prevalence of up to 15% in the normal population and are usually asymptomatic. In severe cases, they can be associated with vague scrotal pain or even worm-like varicose veins in the scrotum. The biggest danger of varicocele to men is that it may lead to a decrease in semen quality and thus male infertility, and studies have shown that 40% of the male infertility population is associated with varicocele. Currently, the treatment of varicocele is mainly surgical, and the commonly used surgical methods are: open extraperitoneal high ligation, laparoscopic high ligation, percutaneous puncture vein injection of sclerosing agent, and the most advanced microscopic subcircumferential spermatic vein ligation. With the aid of direct microscopic view and Doppler microprobe, the testicular artery and its branches and lymphatic vessels are protected to the maximum extent, while all branches of the internal spermatic vein, including the leading vein and the varicose external spermatic vein, are fully and completely ligated, avoiding recurrence and various complications and ensuring the efficacy of treatment. Studies have shown that patients with varicocele combined with infertility have a significant increase in postoperative conception rate and semen examination parameters, especially in young patients with severe varicocele; currently, it is believed that adolescents with varicocele should be treated with surgery as early as possible. We hope that all patients will recognize and pay attention to this common disease, and visit the specialist clinic as soon as possible to consult and discuss the surgical treatment plan with the doctor.
