目的：为睾丸神经切除术提供解剖学基础。方法：在３０侧成年男性尸体标本上对精索腹股沟管腹环至皮下环段进行了解部学观测。结果：输精管位于精索后内方，睾丸动脉位于中央，被蔓状静脉丛包绕，输精管动脉位于精索内生殖股神经生殖支与输精管静脉之间稍后方，髂腹股沟神经位于精索的外侧、生殖股神经生殖支位于精索的内侧，与精索伴行。结论：在显微外科睾丸神经切除术中应注意寻找保护睾丸动脉和输精管动脉，切断睾丸神经，根除交感神经的支配，即可阻断睾丸神经的痛觉传导。
Objective: To provide anatomic basis for testicular neurotomy. Methods: Anatomy of the genital area of the inguinal to subcutaneous segment of the spermatic cord in 30 adult male cadaver specimens was studied. Results: The vas deferens were located in the posterior aspect of the spermatic cord. The testicular artery was located in the center and was surrounded by the plexiform veins. The vas deferens were located slightly behind the reproductive branch of the reproductive nerve and the vas deferens in the spermatic cord. The iliovaginal groin nerves were located outside the spermatic cord , Genital nerve reproductive branch in the spermatic cord medial, accompanied by spermatic cord. Conclusion: In the microsurgical testicular neurotomy, attention should be paid to protect the testicular artery and vas deferens arteries, cut off the testicular nerves and eradicate sympathetic innervation, which can block the painful conduction of the testicular nerve.
