Arterial supply and innervation
The seminal vesicles receive their arterial supply in a way that is similar to that of the prostate gland. The primary arterial supply is from the inferior vesical, internal pudendal, and middle rectal arteries. These 3 primary sources all arise from the anterior division of the internal iliac artery.
The innervation to the seminal vesicles is from the sympathetic nervous system. These fibers originate from the inferior hypogastric plexus.
