20% – 40% of men suffer from varying degrees of varicocele. Especially, our professional doctors encounter a lot of cases of this type during military recruitment medical examinations! It is important to know that varicocele, can affect testicular development, sperm production and androgen synthesis is clear. Early surgical treatment of varicocele in adolescence is advocated, and postoperative testicular development can be improved, with less impact on testicular spermatogenesis in adulthood. The aim of surgery for adult varicocele is to improve semen quality and reduce the probability of testicular atrophy and reduced androgen levels. To treat or not to treat adolescent spermatozoa, the condition of the balls is decisive: According to various guidelines and data from Europe, the United States and China, the treatment of adolescent spermatozoa is not determined by the degree of varicocele nor by the combination of the so-called “Nutcracker syndrome”, but mainly by the “balls The main determinism is “egg pain” (taking surgical treatment as an example, microsurgery is recommended as a priority): 1. This “egg pain” is generally refers to the varicose ipsilateral balls mild to moderate, long standing or long walk after the discomfort, lying down to relieve the more obvious. The opposite side of the egg pain or severe unbearable egg pain does not belong to this list. 2.Small egg. The affected side (usually the left side) is 2ml or 20% smaller than the contralateral side, which is a clear indication for surgery, and there are also studies that suggest that surgery of 10% smaller than the contralateral side is also valuable. The above two points have a high index of recommended surgery, and surgery is generally recommended. And the following two points are relative indications, which can be done or not. In the case of bilateral varicocele, surgery may be recommended due to the lack of “normal” eggs as a control and the absence of an accepted age-related testicular volume standard, but the choice of surgical treatment or observation is somewhat subjective, so the details and risks of surgery must be fully discussed with the patient’s parents and the patient himself. Therefore, the details and risks of surgery must be fully discussed with the patient’s parents and the patient himself. If a decision cannot be made on the previous 3 points, for older adolescents a semen analysis may be considered to decide whether to treat or not, or to choose hormone stimulation experiments. It has been reported that semen quality improves in about 60% of patients after surgical treatment, with an improvement in vitality of about 70%, sperm concentration of 51% and morphology of 44%. The surgical approach to varicocele is focused on carefully and completely ligating the spermatic veins under a microscope, preserving the testicular arteries and preventing testicular atrophy and testicular torsion.
