Vascularization of the male penis.
OBJECTIVE
The study of the features of the blood supply of a penis of the man.


METHODS
Macromicropreparation, angiography, corrosion method, morphometry, statistical method.


RESULTS
The penis has three venous collector-executing outflow of blood. First of them is submitted surface dorsal vein, which is shaped from small-sized venous vessels of skin, subcutaneous fat and surface fascia of penis. The beginning deep dorsal vein, which will derivate second venous collector, gives veniplex of head of the penis. The spongy veins outstanding as third venous collector, reach the bulb of penis, where they receive small-sized bulbar vein. The arterial blood supply of penis happens at the expense of external and internal pudendal arteries. The external pudendal artery starts from an internal wall of femoral artery on 2.5-2.7 cm below inguinal ligament. In some cases (8%) the artery starts by two trunks--forward and back. The internal pudendal artery is main source of blood supply of penis of the man. It removes from forward trunk of internal iliac artery independently in 50% of cases. In remaining cases it or removes from this artery by one trunk with lower gluteal (36%), common trunk with the upper and lower gluteal arteries (4%), or with upper gluteal (8%), or with obturator artery (2%). Besides in the arterial blood supply of penis take part bulbar, urethral, dorsal and deep arteries of penis.


CONCLUSIONS
The penis receives blood from external and internal pudendal arteries, which are very variable. The venous blood of the penis flows off in three types of veins.
