(A) Three-dimensional reconstruction of the penis of a 72-year-old human cadaver showing the trajectory of the arteries of the penis with regard to the corpora cavernosa (CC) and the corpus spongiosum (CS). (B) The same image after the CC and CS have been made transparent, showing the different anastomoses between the arteries of the penis. The dorsal arteries of the penis (DAP) played a role in the vascularization of the CC via the perforating branches (S1), which ran through the tunica albuginea (TA) to anastomose with the cavernous arteries (CA) or to ensure solely the vascularization of the one-third distal part of the CC. The bulbo-urethral arteries (BUA) and the urethral arteries (UA), highly anastomosed with each other, were situated outside of the TA of the CS. These were the UAs that received the shunt (S2) stemming from the CA, reinforcing the vascularization of the CS and the urethra. CP, crura of penis; G, glans.
