[Drainage of the erectile organs in the rat]

The retro-pubic veinous circle of the male rat was investigated on the both sides: anatomic and functional aspect. The dorsal vein of penis in the male rat run into a retro-pubic veinous circle. This circle receive the anterior vesical veins too. The internal pudendal vein and the anastomotic vein begin in this circle, and go together to the iliac vein. From the retro-pubic veinous circle, there is a triangular circulation between the internal pudendal vein, the anastomotic vein and the iliac vein. Angiographies performed on rats in vivo, indicates that the anastomotic vein is effical for the drainage of the retro-pubic circle only if the flow of the penis dorsal vein is sufficient. These conclusions are proved by experimentation on dead rats.
