How do penis pumps work to prevent penis shrinkage?

Erectile dysfunction is not the taboo topic it once was 20 years ago.  With high levels of visibility surrounding sexual dysfunction as a medical concern, it is no longer ignored, but now considered a treatable condition. With growing knowledge, more finite characteristics of ED are focused on within the medical community and expanding definitions of the condition are emerging.

Premature ejaculation, Peyronie’s disease, and penis shrinkage (sometimes known as penile atrophy), are surfacing as variations of impotence and considered subsets of erectile dysfunction as a general condition. These subclasses can be uniquely and specifically treated with distinct medical interventions.

Before going into “how do penis pumps work to prevent penis shrinkage,” let’s define the condition known as penis shrinkage.

Penis Shrinkage

Penis shrinkage is not an uncommon condition.  Penis shrinkage can be a reduction in length or girth (width) of the penis, or even both.  When we refer to penis shrinkage in this commentary, we are not speaking of the natural process of becoming flaccid, but rather the  loss of length or girth of the penis when either in an erect or flaccid state.

A man’s self-esteem can be effected by the condition.  However, much more than self-worth is at stake. Penile atrophy or penis shrinkage can be associated with tissue loss or cell death.

Causes of penis shrinkage

Penis shrinkage can occur for several reasons:

  • A buildup of plaque in the arteries in the penis
  • Obesity connected with absence of blood flow to the penis
  • Radical prostatectomy resulting in penis shrinkage for 70 percent of men who have had the surgical procedure.
  • Peyronie’s disease, or curvature of the penis, which can cause shrinkage
  • Diabetes and penis shrinkage are highly correlated
  • Medications can be a cause of penis shrinkage, especially if side effects eliminate the occurrence of nocturnal erections

What do penis pumps do?

Penis pumps are known by multiple descriptions, including: erectile dysfunction pump, vacuum erection device, or penile pump, but they each act in a similar way.  They create penile rigidity.

To operate, place the penis in an open-ended cylinder that has a pump or negative pressure device on the opposite end. Activate the pump.  Blood is drawn into the penis in order to create an erection.

The process of “penis pumping” is a blood-filling activity that increases blood flow and expands penile tissues.  This procedure has the capacity to break down or remove plaque buildup in penile arteries, prevent or reverse tissue atrophy, and bring oxygen to penile tissues.

It is important to point out that it is not the penis pump that prevents penis shrinkage and accomplishes the above-mentioned results; it’s the regular creation of penile rigidity or erections that prevents penis shrinkage.  The penis pump is simply a helpful tool, when used properly, for the creation of repetitive penile rigidity.

How to increase blood flow to penis

Blood flow is the key to penile health and preventing penis shrinkage.  Erections that are created for sexual intercourse are blood-filling events that increase blood flow to the penis. Nature seems to have found a way to compensate for the fact that most men don’t have sexual intercourse on a daily basis.

In the absence of, or in addition to, having sexual intercourse on a daily basis, the body naturally creates 3-5 erections during REM sleep, called nocturnal erections or nocturnal penile tumescence.

If you have a physical condition that has caused erectile dysfunction, you likely have lost nocturnal penile tumescence and the accompanying blood flow and oxygenation that prevents penis shrinkage.

Consequently, any medical intervention that creates regular erections has the ability to bring blood flow to the penis.  This includes the following:

  • Oral ED medications
  • Penile injections
  • Penile urethral suppositories
  • Penis pumps

Erectile dysfunction exercises

Erections keep tissues healthy and help prevent or reverse penis shrinkage. Nocturnal erections could be considered erection exercises that keep regular blood flow and oxygenation present in penile tissues. As a result, if nocturnal erections are the standard erection exercise, 3-5 erections are normally created and released in healthy men in a 24-hour cycle.

In order to exercise the penis in the absence of nocturnal erections, an erection must be created and released 3-5 times in a 24-hour period. However, most people who suffer from ED should be aware of medical interventions that can potentially replicate the healthful benefits of nocturnal erections.

If you are a candidate for oral ED medications, they can be used to produce erections and bring blood flow and oxygenation to the penis.  Oral ED medications can create an erection that will become flaccid or released.

Penile injections can be used to exercise the penis.  If you inject the penis with a needle, it will become erect. The erection will become flaccid at some point.

This is also true with penile urethral suppositories. If you create an erection using this medical intervention, blood will flow into the penis and then out again.

Why are penis pumps great tools to exercise the penis?


  • You can create and release 3-5 erections in one session, which is somewhat similar to what happens naturally during REM sleep.
  • With other treatments, you can control the creation of the erection, but a penis pump is the only treatment listed in which you have complete control over the “release” of the erection.
  • There are no drugs or needles involved, so the toxicity of drug exposure is not an issue. This is also true in that multiple exposure to injections and needles is not an issue.
  • Other treatment modalities mentioned would have a cost associated with each use, whereas a penis pump is a one-time expenditure.
