Anatomic study of arterial and venous cavernospongious shunt of the human penis: surgical finding

The vascularization of the penis corpora cavernosa and the corpus spongiosum of fœtus, children and adults was studied via intra-vascular injection with gelatenous india ink. The microscopic vision of sagittal and transvers sections of the penis showed perforate deep arterial system of the cavernosa directly anastomosed the urethral submucosal arteries in order to establish the shunt between the corpora cavernous arteries and spongious arterial network. Those vascular connection systems of the penis provided well diffusion of the drugs. [Copyright &y& Elsevier]
