Editing Epididymis and Vas Deferens (section)

=== Arterial supply ===

* '''Main blood supplies (2):'''
*# '''Superior and the medial epididymal arteries'''
*#* '''Arise from the testicular artery''', which arises from the aorta
*#* '''Supply the caput and corpus epididymis'''
*# '''Inferior epididymal artery'''
*** '''Arises from the artery of the vas (vasal/deferential artery)''', which arises from the superior vesical artery, which arises from the internal iliac artery
*** '''Supplies the cauda epididymis'''
** '''These form an extensive interconnection'''
*** '''Clinical implications (3)'''
***# '''If the artery of the vas is ligated from previous vasectomy, the blood supply to the epididymis from the testicular artery is adequate'''
***# '''If the testicular artery is ligated, the blood supply to the epididymis from the artery of the vas is adequate'''
***# During vasoepididymostomy or vasovasostomy, '''the epididymis can be intentionally dissected off the testis and mobilized to the caput, with the inferior and medial epididymal arteries intentionally ligated without adverse consequence. As long as the superior epididymal artery remains intact, the blood supply to the epididymis will be adequate'''
