Dorsal artery of the penis

The dorsal artery of the penis is a bilaterally paired terminal branch of the internal pudendal artery which passes upon the dorsum of the penis to the base of the glans penis, where it unites with its contralateral partner and supply the glans and foreskin. The dorsal artery of the penis provides blood supply to the skin and fascia of the penis (including the foreskin), and the erectile tissues of the penis (especially the glans penis).
