Editing Testicle (section)

====Blood supply and lymphatic drainage====
The testis has three sources of arterial blood supply: the [[testicular artery]], the [[cremasteric artery]], and the [[artery to the ductus deferens]].<ref name="Goldenberg">{{Cite book|last1=Goldenberg|first1=Etai|last2=Benjamin|first2=Tavya G.R|last3=Gilbert|first3=Bruce R.|title=Practical Urological Ultrasound|chapter=Scrotal Ultrasound|date=2020|publisher=Springer Nature|isbn=978-3-03-052309-1|page=80|chapter-url=https://books.google.com/books?id=QU8AEAAAQBAJ&pg=PA80|access-date=2022-07-06|archive-date=2023-06-29|archive-url=https://web.archive.org/web/20230629160234/https://books.google.com/books?id=QU8AEAAAQBAJ&pg=PA80|url-status=live}}</ref> Blood supply and [[lymphatic drainage]] of the testes and scrotum are distinct:
* The paired testicular arteries arise directly from the [[abdominal aorta]] and descend through the [[inguinal canal]], while the scrotum and the rest of the external genitalia is supplied by the [[internal pudendal artery]] (a branch of the [[internal iliac artery]]).<ref name="Steger 2"/><ref name="Tortora">{{Cite book|last1=Tortora|first1=Gerard J.|last2=Nielsen|first2=Mark|title=Principles of Human Anatomy|date=2017|publisher=John Wiley & Sons|isbn=978-1-11-944446-6|page=486|url=https://books.google.com/books?id=e0rcDwAAQBAJ&pg=PA486|access-date=2022-07-06|archive-date=2023-06-29|archive-url=https://web.archive.org/web/20230629160234/https://books.google.com/books?id=e0rcDwAAQBAJ&pg=PA486|url-status=live}}</ref>
* The testis has collateral blood supply from the cremasteric artery (a branch of the [[inferior epigastric artery]], which is a branch of the [[external iliac artery]]), and the artery to the ductus deferens (a branch of the [[inferior vesical artery]], which is a branch of the internal iliac artery).<ref name="Pua">{{Cite book|last1=Pua|first1=Bradley B.|last2=Covey|first2=Anne M.|last3=Madoff|first3=David C.|title=Interventional Radiology: Fundamentals of Clinical Practice|date=2018|publisher=Oxford University Press|isbn=978-0-19-027625-6|page=533|url=https://books.google.com/books?id=edB2DwAAQBAJ&pg=PA533|access-date=2022-07-06|archive-date=2023-06-29|archive-url=https://web.archive.org/web/20230629160235/https://books.google.com/books?id=edB2DwAAQBAJ&pg=PA533|url-status=live}}</ref><ref name="Berney">{{Cite book|last1=Berney|first1=Daniel M|last2=Ulbright|first2=Thomas M.|title=Genitourinary Pathology: Practical Advances|chapter=Anatomy of the Testis and Staging of its Cancers: Implications for Diagnosis|date=2015|publisher=Springer|isbn=978-1-49-392044-0|page=436|chapter-url=https://books.google.com/books?id=97RnBwAAQBAJ&pg=PA436|access-date=2022-07-06|archive-date=2023-06-29|archive-url=https://web.archive.org/web/20230629160304/https://books.google.com/books?id=97RnBwAAQBAJ&pg=PA436|url-status=live}}</ref> Therefore, if the testicular artery is ligated, e.g., during a Fowler-Stevens [[orchiopexy]] for a high undescended testis, the testis will usually survive on these other blood supplies.<ref name="Aboumarzouk">{{Cite book|last=Aboumarzouk|first=Omar M.|title=Blandy's Urology|date=2019|publisher=John Wiley & Sons|isbn=978-1-11-886336-7|page=747|url=https://books.google.com/books?id=WsaKDwAAQBAJ&pg=PA747|access-date=2022-07-06|archive-date=2023-06-29|archive-url=https://web.archive.org/web/20230629160244/https://books.google.com/books?id=WsaKDwAAQBAJ&pg=PA747|url-status=live}}</ref>
* Lymphatic drainage of the testes follows the testicular arteries back to the [[paraaortic lymph nodes]], while lymph from the scrotum drains to the [[inguinal lymph nodes]].<ref name="Steger 2"/><ref name="Berney"/>
