[citation needed] It arises from the internal pudendal artery posterior to the inferior edge of the symphysis pubis[1] while the internal pudendal artery is situated between the two fasciæ of the urogenital diaphragm (deep perineal pouch).

[citation needed] It traverses the pelvic floor, then immediately enters the corpus cavernosum penis.

[1] It runs anterior-ward in the center of the corpus cavernosum penis, to which its branches are distributed.

[citation needed] In the center of the corpus cavernosum, it splits into an anterior branch (which supplies the anterior two-thirds of the corpus cavernosum), and a recurrent branch (which supplies the posterior one third of the corpus cavernosum).
