Blood flow: Erections work when a vigorous arterial supply fills the spongy tissue of the penis. This causes the penis to become erect and also crushes the outflow veins to prevent the erection from immediately going down. If there is not a strong enough inward arterial flow, the penis may not become fully erect, or will not suppress the vein enough to reduce outflow and keep the erection.
