Penis enlargement pumps work by creating a vacuum around the penis. As the vacuum increases – that is, air is pumped out of the cylinder surrounding the penis – blood is drawn into the erectile chambers, engorging the penis to its maximum capacity.
It’s just like over-inflating a tyre with air.
Just like a tyre – thanks to the elasticity of the penile tissues – there’s naturally some room for expansion.
The problem is however, that just like a tyre, there’s also a finite amount to how much expansion can take place.
Pump too hard and you can literally experience the penile equivalent of a ‘blow-out’ – rupturing either a penile artery or the sheath of tissue covering the erectile chambers (called the tunica albuginea). More about these potential problems below.
The idea behind this is very similar to penis enlargement exercises – to stretch and expand the erectile tissue so that the penis is naturally capable of holding more blood.
But although on the surface this seems like a credible alternative, in practice the results produced and the level of risk involved are quite different.
What You Can Expect
One positive thing to say about penis pumps is that they definitely enlarge your penis temporarily. It’s also true to say that as your penis adapts to regular pumping over several months and years, it’s possible to temporarily pump up larger and larger.
But the vast majority of veteran pumpers state that even after several years of regular pumping, they still make no permanent gains. Once removed from the cylinder, the penis quickly reverts back to its original size, usually within a couple of hours.
A few men do claim to have made permanent gains in penis size. But even for these lucky few, they state that it takes well over a year of regular pumping just to gain an extra inch.
Why Pumps Produce Little Permanent Gains
The reason pumping promotes much slower gains than natural penis enlargement is probably due to its effect on blood circulation. Whereas penile exercise actively improves blood flow to the penis and ensures healthy tissue growth, the use of a penis pump does exactly the opposite.
That’s because during a pumping session, the vacuum pressure cuts off blood circulation to the penis. And without a continuous flow of fresh oxygenated blood, the penile tissue slowly starves of oxygen.
In the long term this is more likely to result in nerve and tissue damage, as opposed to permanent penile growth.
It’s for this reason – to prevent the penile tissues from being starved of oxygen – that you should only pump for relatively short periods of time per session – no more than 10 – 15 minutes.
Penis pumps not only cut off circulation during use, but they also have no effect on improving and boosting the normal flow of blood to the penis. Again, a strong, healthy supply of blood is absolutely vital for both overall penile health and tissue growth.
Risk of Injury
Because penis pumps promote slow (if any) gains, many men make the mistake of applying too much pressure or pump for too long in an attempt to speed up gains.
Over pumping in this way commonly results in ruptured capillaries and blood vessels just beneath the skin, causing large bruises to appear on the penile shaft.
In severe cases, the pressure build up from the use of a penis pump can be so extreme that men actually end up rupturing one of the delicate penile arteries that supply the penile shaft with blood; or alternatively split the tunica albuginea – the ‘tyre wall’ that contains the erectile chambers and provides rigidity to the penis during erection.
What happens then?
Well, such severe internal trauma can lead to conditions such as Peyronie’s Disease (resulting in permanent disfigurement) or impotence. In both cases, surgical intervention is the only potential solution for correcting such damage.
More frequent, but less serious side effects of over pumping include blisters and slight discoloration to the skin. Over pumping can also result in fewer, softer erections which are difficult to maintain for any length of time – again, this is probably due to the negative effect pumping has on blood circulation to the penis.
To avoid the risks of over pumping, it’s vitally important to only use low level vacuum pressures, and to carefully monitor the pressure you’re using through the use of a device with an accurate and reliable pressure gauge.
So to sum up, penis pumping can lead to the following issues:
- Lymph blisters on the penile skin. These can be particularly painful and slow to heal if they occur on the penile head.
- Superficial bruising to the penile shaft.
- A general darkening of the penile skin caused by reduced blood flow.
- Reduced blood flow during use can gradually starve the penile tissues of oxygen – leading to irreversible nerve and tissue damage.
- Extreme pressure or overly frequent use can rupture penile arteries or split the sheath of tissue surround the erectile chambers.
I’ve provided more in-depth advice about potential penis pumping injuries in this article.
There are a couple of penis pumps on the market that claim to be FDA certified medical devices. From this, you’d probably think that they’re certified specifically as a safe means of penile enlargement.
However, it’s important to appreciate that those devices that have gained medical certification, have done so not as a means of increasing penis size, but as a means of treating impotence.
That of course, is no reason to dismiss a penis pump as ineffective when it comes to delivering improvements in size – because as we’ve already noted, they can produce quite impressive temporary improvements.
The simple point however, is that you shouldn’t buy a penis pump under the false illusion that it’s medically endorsed as an effective method of penis enlargement – that medical endorsement relates specifically to their use as anti-impotence aids.
I personally wouldn’t recommend using a penis pump if you’re serious about permanently enlarging your penis. They will temporarily increase your size (usually for a couple of hours), but for the vast majority of men permanent gains are never achieved.
Unlike penis enlargement exercises, penis pumps do not promote a healthy flow of blood to the penis, which is necessary for healthy tissue growth. And combined with the possibility of serious injury, the method produces far too little results to justify the level of risk involved.
If you do want to experience the temporary penis size increases that can be achieved through the use of a penis pump however, make sure that you buy one that has been carefully designed to apply very accurate and safe levels of pressure. Doing so is essential to avoiding potential injury. One of the better, high end devices that provides the best balance of impressive temporary size increases and safe pressure levels is the Penomet pump.
