"Ligamentous Laxity" is a term used to describe ligaments that become loose or stretched out.
This is a very important concept in the spine, as the ligaments help hold the vertebrae in place.
The looseness of the ligaments compromises the integrity of the vertebral column and means it can be more easily injured during trauma.
The same is true of other joints, such as the ankle and knee, as ligaments are utilized to keep the joints in proper positioning.
This proper positioning allows them to function at their greatest possible efficiency.
If we explore natural penis enlargement we find that one of the mechanisms of increasing the length of the penis is through the stretching (or increasing the laxity) of the penile ligaments.
While these ligaments don't connect bone to bone, they do connect soft tissue to bone (but not in all cases).
The best thing about this type of laxity is that we don't have to be worried about losing joint integrity, as the ligaments are not a bone-bone interface.
But by creating laxity in these penile ligaments (this is usually done by stretching the penis and corresponding ligaments through specific exercises) we increase the length of the penis during the flaccid, as well as the erective state.
This is great, after all, because this is what we want to accomplish.
What happens now is that because the penis can extend to greater lengths (due to the lengthening of these ligaments) we have also compromised this ligamentous structure (in the process) and affected an anatomical change in the penis.
From a hemodynamic standpoint (blood flow and blood pressure - which is what creates an erection) we now have to be able to pump more blood into the penis to get it to full erectness with our newly-found length.
This means that the heart has to work a bit harder to get that blood and blood pressure into the penile cavities.
It's a minimal change, but real.
The arteries that feed the penis may increase in size during the enlargement process, but this is difficult to prove.
If the same-sized arteries are responsible to feed a bigger penis, there will be some compromisations involved.
The next most logical question should be: "So...
If I am just encouraging more of the hidden part of my penis (the part stuck inside the pelvis) to extend to longer lengths, why should this be anything to consider?" Because now there is more penile tissue with more weight and volume outside of the penis.
Gravity has an affect on the increased weight and it takes more blood pressure to counter-balance this added weight to keep the penis erect.
We have also changed the fulcrum-erection point which puts more strain on the ability of the penis to create an erection.
Plus, you're going to need more blood pressure to compensate for the increased "looseness" of this newly-created ligamentous state.
Under most circumstances this is hardly a problem for a man who is in relatively good physical condition - especially from a cardio-vascular point-of-view.
But keep in mind that there will be some differential created by this form of enlargement process.
So please keep in mind that it is also important to exercise your heart and keep in overall good physical condition.
It will also give you more stamina and penile strength when making love, too, so it is definitely worth your while.
