The venous drainage of the testis of the laboratory rat was observed in 31 animals. The right testicular (internal spermatic) vein drained directly into the right common iliac vein in 77.4%, and into the inferior vena cava in 22.6% of the animals. The left testicular vein drained into the left common iliac vein in all animals, but in 90.3% there was also an accessory branch of the testicular vein draining into the left renal vein. These observations suggest that in the rat the exact anatomy of the venous drainage of each testis should be identified prior to undertaking any surgical procedure on the testis where the venous vasculature plays a major role such as testicular transplantation or the creation of an experimental varicocele.
在31只实验大鼠中观察了睾丸的静脉引流情况。右侧睾丸（精索内）静脉在77.4%的动物中直接汇入右髂总静脉，在22.6%的动物中汇入下腔静脉。左侧睾丸静脉在所有动物中均汇入左髂总静脉，但在90.3%的动物中，还有一条睾丸静脉的副支汇入左肾静脉。这些观察结果表明，在大鼠中，在对睾丸进行任何手术操作（如睾丸移植或创建实验性精索静脉曲张，其中静脉血管系统起主要作用）之前，应先确定每个睾丸静脉引流的确切解剖结构。
