From which artery does the prostatic artery arise?

• A. Inferior vesicular artery
• B. Middle rectal artery
• C. Internal pudendal artery
• D. Superior vesical artery

Answer: (A)

The prostatic arterial supply comes mainly from the inferior vesical artery. This artery, a branch of the internal iliac, typically gives multiple prostatic branches that enter the prostate and form a dense vascular plexus around the gland, providing most of the gland’s blood flow. Other pelvic arteries can contribute small prostatic branches in some individuals, but they are not the primary source. The middle rectal artery mainly supplies the rectum, the internal pudendal artery mainly supplies perineal and erectile tissues, and the superior vesical artery primarily supplies the bladder. Those vessels may anastomose with prostatic branches, but the main supply is the inferior vesical artery.
