Abstract：
OBJECTIVE: Testicular volume (TV) is known to be one of the main parameters for testicular function (TF). This study was conducted to re-evaluate the indications of a varicocelectomy based on a survey of preoperative TV results in left-side varicocele patients considered to reflect the detrimental effects of a varicocele on TF.
METHODS: TV results of infertile patients determined using ultrasonography by a single expert physician were retrospectively evaluated.
RESULTS: Of 590 examined patients, 424 had no varicocele findings (Group A), while 148 had a left-side varicocele (Group B). Group B was subdivided based on varicocele grade into Group B0 (subclinical), B1 (grade 1), B2 (grade 2), and B3 (grade 3). Comparisons of left-side TV showed no significant differences for grade among Group A, B0, and B1, whereas that for Group B2 and B3 was significantly lower as compared with Group A (p < 0.01, 0.02, respectively). The median TV of Group B I (composed of Groups B0 and B1) was 9.8 cm3, while that of Group B II (Groups B2 and B3) was significantly lower at 8.4 cm3 (p < 0.05). In contrast, a comparison of right TV values identified no significant differences among the groups (p = 0.918).
CONCLUSIONS: A varicocelectomy should be performed for patients with a grade 2 and 3 varicocele for ameliorating testicular function.

摘要：
目的：已知睾丸体积（TV）是睾丸功能（TF）的主要参数之一。这项研究旨在根据对左侧精索静脉曲张患者的术前电视结果的调查，重新评估精索静脉曲张切除术的适应症，这些结果被认为反映了精索静脉曲张对TF的有害影响。
方法：回顾性评估由一名专家医师使用超声检查确定的不孕患者的电视结果。
结果：在590名接受检查的患者中，424没有精索静脉曲张发现（A组），148例左侧精索静脉曲张（B组）。B组根据精索静脉曲张等级细分为B0组（亚临床），B1（1级），B2（二级），和B3（3级）。左侧电视的比较显示，A组之间的等级没有显着差异，B0和B1，而B2和B3组的B0和B1明显低于A组（分别为p<0.01，0.02）。BI组（由B0组和B1组组成）的中位TV为9.8cm3，而BII组（B2和B3组）在8.4cm3处显着降低（p<0.05）。相比之下,对正确的TV值进行比较,发现各组间无显著差异(p=0.918).
结论：对于2级和3级精索静脉曲张患者，应进行精索静脉曲张切除术以改善睾丸功能。
