What exactly is venous leakage?

Hi guys,

Have been reading about venous leakage recently both on this forum and the wider web. I've found there isn't too much consensus on what it actually is (or perhaps it's my poor understanding of the terminology). Examples of what I've read:

1. It's a failure of the 'valve system' of in-flowing blood veins. Therefore there is some back-flow.
2. The emissary veins are not sufficiently compressed by tunica albuginea due to it's lack of expansion. Blood therefore continues to be released from the corpus Cavernosum.
3. A vein is punctured and leaking (if so which vein?)
4. The Tunica albuginea itself is punctured or perforated therefore blood loss from corpus cavernosum.

So then, is it one of these or all of them? Can anyone help clarify?

Many thanks

That's the answer
The veins suppose to close after erection is achieved not to let the blood out.
To test this issue, a doctor will induce you an erection and then monitor the blood flow out.

Maybe it is terminology but I would select #2. There is no "valve system" and veins carry blood away from the penis. So I don't get the "inflowing veins" terminology.

I have studied the process which causes an erection and it is quite an involved process. As the penis fills with blood, the corpora chambers fill and press against the Tunica internally. Pressing against the walls "squeezes" the veins reducing the amount of blood flowing out. Essentially trapping the blood inside. This lasts until PDE5 enzymes are triggered and these will then help relax the arterial walls and your erection subsides. ED is caused when PDE5 is over active or triggered prior to orgasm. And is why drugs like Viagra and Cialis are classified as PDE5 inhibitors.

Venous leak is what all the people think they have, when they suffer from Ed, when they could have arterie blockage. In other words, good blood trapping capabilities, but poor inflow on the penile arteries. :-P

Erection consists of two phases.  The first is the "vascular phase" in which the helicine arteries of the penis dilate and fill the corpora sinusoids with blood and this then compresses the emissary veins, slowing the blood flow out of the penile venous system into the pelvic veins.  This results in a penile blood pressure that is exactly the same as the person's blood pressure at that time (such as 120/80).  This is what most would understand as a soft erection.  This vascular phase should be immediately followed by the "muscular phase" in which the paired ischiocavernosus muscles attached around the penis base (crux) originating from the ischial portions of the pelvis, strongly contract and compress each crux causing penile blood pressure to rise far above the person's blood pressure.  This then results in a rigid erection.  So venous leak is a condition where blood is leaking back into the pelvic veins either from a structural abnormality affecting the vascular phase or a weakness or dysfunction affecting the ischiocavernosus and therefore affecting the muscular phase.
