How Xialla works to correct venous leak


Xialla is very simple and looks similar to an enhanced cock ring. So isn’t is just another sex toy like the rings I can buy at an adult store for a few dollars? The short answer is no. Xialla is a medical device that works in a subtle and unique way to correct venous leak, or blood outflow. The full explanation requires a bit of background into the mechanics of an erection.

How an erection works

An erection is not a simple thing. In fact, sometimes it seems it’s a miracle erections happen at all, they’re so complicated. For an erection to happen requires two fundamental things; blood must flow into the penis, and blood must be blocked from flowing out faster than it flows in.

Blood flows into the penis through the cavernosal arteries deep within the penile shaft. These arteries dilate (expand) when a man is sexually aroused, increasing blood flow to the penis to start the erection. Normally blood to the penis flows back out through the penile venules and deep dorsal vein. However when an erection starts, the corporal tissue (the main spongy part of the penis shaft) fills with blood and starts to get hard. As it does it squeezes (compresses) the veins and venules, slowing the flow of blood out of the penis. As long as the flow in (arteries) is faster than the flow out (veins) the erection is maintained.

How erections are lost

Two things can cause loss of erection, leading to ED; blood flow into the penis is too slow (arteries), or blood flow out of the penis is too fast (veins). In either case the balance of flow is altered so that blood flow out exceeds blood flow in, and the erection is lost. This condition is called venous leak.

Fixing the problem

Now it becomes clear that there are two options for fixing ED and restoring the erection, either increase blood flow into the penis, or decrease blood flow out of the penis. Increasing blood flow to the penis is what PDE5 inhibitor drugs do, by relaxing the arteries.

Why drugs often aren't enough

However, for many men PED5 drugs aren’t effective, because even though the blood flow in is enhanced the blood flow out is too fast. This can happen when the erection doesn’t get hard enough to compress the veins (to slow the outflow), for instance when a man is not easily as aroused later in life as he was when younger. It can also happen when the veins harden with age, becoming more difficult to compress.

What these men need is a way to compress (but not close completely) the deep dorsal vein and penile venules to slow the blood flow out of the penis.

That is what a “cock ring” attempts to do. Stretched and placed at the base of the penis, the cock ring uses simple elastic pressure to partially close the veins and venules, slowing blood flow out of the penis.

Why cock rings don't work well

It seems like a simple and perfect solution, except for one problem. Cock rings don’t work well. The solution to the problem is the key invention of Xialla that turns it from a less-than-effective cock ring into a highly effective medical device.

The reason a cock ring doesn’t work well lies at the heart of the sexual act, and the fact that sex is not a gentle motion. On the contrary, penile thrusting is quite vigorous. Many would say the more vigorous the better! The problem is that with each thrust the cock ring is pushed backwards a bit and with each withdrawal it is allowed to slide forwards a bit. Furthermore, the sliding is made easier by the fact that the penile skin is able to slide along the penis freely and nearly friction-free, as any man who masturbates by sliding the skin rapidly back and forth will understand.

So we have a situation where the cock ring is trying to slow the flow of blood, but it’s moving back and forth a bit with each thrust and withdrawal, as the skin moves. The movement doesn’t need to be much, but it’s enough that instead of the ring doing its job, it’s now acting like a small pump, actively squeezing blood along the veins and allowing it to escape instead of trapping it.

And that’s why cock rings don’t work effectively.

Tight rings don't work either

One might think the solution is just to make the ring tighter so that it doesn’t move. But the problem is the extremely low friction of the skin movement. Try this experiment: Make a ring with your thumb and index finger, grab your erection tightly at the base, and then slide the ring along your penis. Try to grab tightly enough to make it difficult to slide. No matter how tightly you grab, the sliding is still extremely low friction. This is the wonder of the human body. Skin slides over flesh with amazingly low friction, much lower than Teflon. So making the cock ring tight doesn’t work. Even if you really try to make it so tight that it can’t slip, then it cuts off all blood flow, both in and out, and makes the penis quickly go cold and numb. Another common attempt at a solution is to have a loop attached to the ring that goes around the scrotum to hold the ring in place. The problem is that the scrotum is able to move back and forth as well, therefore this solution doesn’t work.

What makes Xialla special?

So what makes Xialla so special and makes it work? Xialla is drawn backward firmly against the scrotum and the scrotum itself is drawn backward as far as it will comfortably go, with the result that both Xialla and the scrotum are held securely in place.

With the ring held in place during the thrusting action of sex, the blood in the penile venules and deep dorsal vein is slowed from exiting the penis. The result is a fast forming, firm and long lasting erection.

Xialla also work with other therapies

This also explains why Xialla is not a competitor to oral ED medications. Rather it’s a complement to those drugs. While some men will obtain a good erection with drugs, men for whom the problem is venous leakage may not. About 40% of men fall into this category, and for them the PDE5 inhibitor drugs simply don’t work. For these men Xialla is an ideal option. By slowing blood outflow, their problem is fixed and they are able to obtain an erection. For men with more severe ED, where both low blood flow in and high blood flow out are present, the combination of drugs and Xialla can be effective in enabling an erection.  


Erections are caused by not enough blood flow in, or too much blood flow out (venous leak). Xialla solves the venous leak problem. Xialla works like a cock ring, but unlike a normal ring Xialla is secured in place so that it effectively traps blood. Xialla also works with other therapies that promote blood flow in.
