  • What a penis pump does best at
  • Lots more

Let's get started!


Penis Pump Functionality

In Chapter 1, we'll discuss the functionality of a penis pump.

First, you'll learn about what a penis pump does in a general and big-picture way.

Then, we'll go over the different functions of a penis pump, and how the pump mechanism actually works.

What Does A Penis Pump Do?

A penis pump uses the negative pressure created by a pump to draw blood into the shaft of the penis.

What Are The Functions Of A Penis Pump?

A penis pump has a few functions such as:

  • To increase the size, girth, and length of a penis.
  • To treat erectile dysfunction.
  • To improve the erection quality of a penis.
  • To treat the overall health and functioning of a penis.
  • To treat Peyronie's Disease.

How Does The Pump Mechanism Work?

The penis pump mechanism works by removing air from the chamber to create a vacuum and negative pressure inside the cylinder.

As air is removed from the chamber, the pressure inside decreases. According to Boyle's law, a decrease in pressure leads to an increase in volume, and hence the blood vessels in the penis expand and dilate to fill the available space and volume.

With the blood vessels expanded and dilated, there is an increased flow of blood into the erectile tissues of the penis causing them to become engorged, erect, and in some cases enlarged.


Penis Pump Demographics

In Chapter 2, we'll discuss the demographics and main audience for penis pumps.

First, we'll look at who the main demographics are for penis pumps.

Then, we'll analyze why this audience is the target demographic and deeper inclinations.

Penis Pump Demographics

It's no surprise that the main demographic of penis pump users is men.

Beyond gender, it's difficult to pinpoint specific traits of penis pump users, but we can surmise a few things.

Traditionally penis pumps have probably been used more by older men than younger men since many more older men experience erectile dysfunction. Since penis pumps are an FDA-approved treatment for erectile dysfunction, many older men probably use them as a first option since they are cheaper and less invasive than other options like surgery.

However this trend is changing with access and widespread information, and more younger men are using penis pumps nowadays than ever before due to their desire to enlarge their penis.

We can also deduce that penis pumps are probably used more in developed countries since penis pumps would be categorized as a luxury item rather than a necessity.

Why Do Men Buy Penis Pumps?

There are many reasons why males by penis pumps. Their reasons can span from as straightforward as sexual pleasure, to more complicated like arousal and body image.

But if the question is "what does a penis pump do for men?" the answer is it can do a lot.

  • Increase your sexual confidence.
  • Augment your arousal.
  • Enlarge your penis.
  • Help treat erectile dysfunction and other penile diseases.
  • Improve your self-esteem.
  • Give you greater sexual pleasure and satisfaction.
  • Give your partner greater sexual pleasure and satisfaction.
  • Enhance your penis and sexual health.

Penis Pump Studies

In Chapter 3, we'll take a look at studies and research done on penis pumps and their efficacy.

First, we'll analyze how penis pumps work for erectile dysfunction and Peyronie's disease.

Then, we'll examine some logs and journals of the many men around the world who have self-conducted research.

Penis Pump Studies On Erectile Dysfunction

There are several studies on erectile dysfunction that have found it to be effective at improving erection quality and erectile functioning, especially when combined with medication and counseling.

In a 2021 study published in the journal Andrology, researchers found that the use of a penis pump improved erectile function in men with ED who were unresponsive to ED medication.

The Journal of Sexual Medicine in 2018 found that the use of a penis pump significantly improved erectile function in men with ED.

Another 2018 study published in the Journal of Sexual Medicine investigated the long-term effectiveness of a VED for the treatment of ED. The study followed men with ED who used a VED for up to 5 years and found that the majority of men experienced improvement in their erectile function over time.

A 2015 study published in the Journal of Sexual Medicine found that the use of a penis pump in combination with sildenafil (Viagra) improved erectile function in men with ED who did not respond to sildenafil alone.

Another study published in the International Journal of Impotence Research in 2003 found that the use of a penis pump was effective in achieving and maintaining erections in men with ED who were unresponsive to medication.

Penis Pump Studies on Peyronie's Disease

For Peyronie's disease, a handful of small studies have suggested that the use of a penis pump may be effective in reducing pain and curvature of the penis.

In a 2020 study published in the Journal of Sexual Medicine, researchers found that the use of a vacuum erection device (VED) in combination with penile traction therapy was effective in reducing penile curvature and improving erectile function in men with Peyronie's disease.

Another 2020 study published in the International Journal of Impotence Research found that the use of a penis pump, in combination with low-intensity shockwave therapy, improved the curvature of the penis in men with Peyronie's disease. The study also found improvements in penile pain and sexual function.

In a 2018 study published in Sexual Medicine, researchers found that the use of a penis pump in combination with a traction device was effective in reducing penile curvature and improving sexual function in men with Peyronie's disease.

A 2017 study published in the Journal of Sexual Medicine found that the use of a penis pump in combination with intralesional injections of verapamil (a medication used to treat Peyronie's disease) was effective in reducing curvature of the penis and improving erectile function in men with the condition.

In a 2016 study published in the Journal of Sexual Medicine, researchers found that the use of a VED was effective in reducing pain and curvature of the penis in men with Peyronie's disease.

A 2014 study published in the Journal of Sexual Medicine found that the use of a VED in combination with intralesional injection of interferon alpha-2b (a medication used to treat Peyronie's disease) was effective in reducing curvature of the penis and improving erectile function in men with the condition.

Individual Penis Pump Research On Penis Enlargement

There are many men around the world who use penis pumps for penis enlargement.

There are no official studies because penis enlargement is taboo and falls into the gray category that shouldn't be talked about.

However, here are a few organizations, groups, forums, and resources you can use that have real men who use penis pumps:

1. Thunder's Place -

Thunder's Place is one of the first online forums for penis enlargement. It contains endless pages of before/after photos, progress reports, penis enlargement discovery, pointed discussions and more. It goes back to 2001, more than 20 years ago and is full of men who have grown their penis and shared their journeys and success tips. Check them out to immerse yourself into the world of penis enlargement.

2. Getting Bigger (Reddit) -

Getting Bigger is a public Reddit community that focuses on science based penis enlargement, and men's sexual health and wellness. The community was created in 2020, has grown tremendously over the years, and is the most active penis enlargement community out there. This community is great for cutting edge discovery and logical discussions of the best and latest penis enlargement topics.


Penis Pumps vs. Other Approaches

In Chapter 4, we'll compare penis pumps to other devices and methods available.

First, you'll learn about the other devices and methods a man can use for penis enlargement and how they measure up to penis pumps.

Then, we'll look at some of the main options men have for the treatment erectile dysfunction and how they compare with penis pumps.

Other Penis Enlargement Devices

Penis enlargement is a common hobby practiced by millions of men across the world.

Besides penis pumps, there are a few different penis enlargement devices that men use to increase the length and girth of their penis such as extenders, hangers and clamps. Each of these devices has pros and cons, and has a different effect on penile growth.

Penis Extenders

Penis extenders are long devices that focus on lengthening the penis through small gradual increases in traction.

A penis extender consists of a plastic ring base that goes around the bottom of your penis and stabilizes the device. The base has two metal rods on both sides extending upward, and a plastic support at the top of the two metal rods that holds the penis head or glans.

The metal rods can be adjusted by adding smaller metal pieces to increase the length, or by telescoping the metal rod outward.

The penis head is wrapped in a silicone sleeve on the plastic support for enhanced stabilization and comfort.

Penis extenders work by applying gentle and consistent traction force to the penis thereby stretching penile tissue, causing micro-tears, and promoting new cell growth.

Penis Hangers

Penis hangers are another lengthening device that involves hanging weights from the top of your penis to stretch penile tissue, create micro-tears, and promote new cell growth.

Penis hangers comprise a hanger head which is a plastic cover and silicone sleeve that wraps around the top of your penis and attaches it to a weight. The user then hangs the weight, ideally while standing up, and allows the natural force of gravity to pull and lengthen their penis.

Penis hangers are one of the most effective penis enlargement devices and methods out there today. Its focus on using gravity for natural elongation, and allowing the weight to freely hang, creates an optimal and effective penis enlargement approach.

Penis Clamping

Penis clamping involves using a clamp around the base of the penis to create increased pressure and tension inside the penile cavity to promote girth and length growth.

Penis clamping targets penis girth growth, and is one of the more controversial and dangerous methods for penis enlargement. Applying high pressures to the penis and also restricting blood flow in and out of the penis is the reason why this practice is polarizing.

Penis Enlargement Exercises

There are also many penis enlargement methods that don't require external devices or products, and that can be done manually using only your hands. The most common manual penis enlargement exercises are jelqing and stretching.

Penis Jelqing

Jelquing refers to performing small pulling motions to the shaft of the penis in an outward direction. The user makes an "OK" grip with his thumb and index finger, and starts at the base of the penis, gently squeezing and pull outward from the base towards the tip. Ideally this is done with a lubricant and can be done multiple times.

The purpose of jelqing is to use the internal blood flow to expand, elongate, and engorge penile tissues to promote new cell growth.

Penis Stretching

Penis stretching is pretty self-explanatory and refers to stretching your penis manually with your hands.

There are many ways to do this. You can pull your penis to elongate it, and hold it in that position for a set period of time. You can pull your penis to stretch it, and then rotate it in different directions to stretch the penis tissue at different angles.

Other Penis Enlargement and Erectile Dysfunction Medical Treatment Options

Penis pumps are one of the best devices and approaches for penis enlargement and erectile dysfunction treatment that is affordable under $50, non-invasive requiring no surgery or procedures, and effective with many users seeing results after just the first session.

In addition to these tried and true devices, there are other options that men can choose such as:

1) Surgery: for penis enlargement doctors can perform surgery by cutting the suspensory ligament inside the penis and stretching the skin and shaft downward. For erectile dysfunction treatment, doctors can add a surgical implant into the penis shaft for rigidity during sexual intercourse.

2) Medication: common medication such as Viagra (sildenafil) and Cialis (tadalafil) can enhance blood flow to the penis to help produce and sustain an erection for sexual intercourse.


Penis Pump Performance

In Chapter 5, we start talking about the more "fun" stuff, and how exactly a penis pump can enlarge your penis and what are the best situations for growth.

First, you'll learn about optimal use cases for penis pumps and how they target penis growth.

Then, we'll look at some specific field-tested scenarios and how it's best to use a penis pump for optimal enlargement and performance.

Long-Term Results vs. Short-Term Gains

One of the best aspects of penis pumping for penis enlargement is that you can benefit both from long-term results and short-term gains.

While the name of the game for penis pumping is "slow and steady wins the race", and adhering to a safe consistent penis program will yield permanent results in the long run, you will actually experience short-term gains as well that can be useful in some situations.

Immediately following a pumping session, your penis will stay engorged and enlarged for a certain period of time. The size and duration of your post-pumping gains is dependent on many factors, but in general most men can experience at least 0.25" in girth gains for up to a couple of hours following a pumping session.

If you perform a pumping session every day, your penis will start to be in its post-pumping enlarged state most of the time, and that will slowly become you new baseline or normal size.

We've written an article all about this that goes into detail here: Can You Quickly Enlarge Your Penis?

Penis Pump Performance On Length vs. Girth

Penis pumps in general will target girth more than length. However, many men will experience both girth and length gains, and there are a couple of factors that influence this.

The main factor is the size of the cylinder. If you use a cylinder that is very close in diameter to your erect girth size, then naturally your penis won't have much space to expand into. Even if there is still "space" for it to expand into, if there is not a lot of space, the effects of the pump pressure will elongate your penis more than widen it.

Conversely, if the diameter of your cylinder is a lot larger than your erect girth, and a lot larger relative to the length of the cylinder compared to your erect length, then the pressure of the pump will target the girth of your penis, and may even enlarge it non-uniformly.

It's very important to purchase a cylinder that fits your current penis size and meets your enlargement goals.

Additionally, many men report that using low pressures targets girth more, while medium to high pressures targets both girth and length, but there is no hard evidence to back this up.

Optimal Usage For Penis Pumps

We constantly relate penis pumping to working out since many men have experience working out, and can hence relate to those comparisons.

The best penis pumping program would be one that consistently, safely, and methodically works out your penis. Pumping three times per week at low to medium pressures is much better than pumping once per week at high pressures. Remember that this is a marathon not a sprint.

On the other hand, pumping three times a week at a very low pressure that doesn't "work out" and stress your penis won't be effective for enlargement.

There are many factors that play a role in an optimal penis program and they are:

  • Consistency. Pumping at least three (3) times per week.
  • Methodical. Using a pressure that is high enough to cause expansion and growth.
  • Safety. Keeping track of your pressure and duration and making sure it is not causing any discomfort or injury.

What Does A Penis Pump Not Do

In Chapter 6, we will discuss what a penis pump does not do as it relates to your physical, physiological, mental, and emotional health.

First, we'll objectively look at what a penis pump does not and will not do.

Then, we'll dig a bit deeper and look at the impact a penis pump can have on your mental and emotional state of mind.

What Does A Penis Pump Not Do

A penis pump will help treat erectile dysfunction, it will enlarge and grow your penis both over time and in the short term, and it will give you greater confidence in the bedroom.

But there are many things that penis pumps do not do such as:

  • They won't all of a sudden make you attractive or a ladies man
  • They cannot address and heal underlying health issues that lead to erectile dysfunction like cardiovascular problems or diabetes.
  • They won't all of a sudden make you great in bed.
  • They aren't a substitute for intimacy and genuine connection.
  • They may not be able to address deep-seated insecurities and psychological issues.
  • They won't address many serious relationship issues.

Downsides To Penis Pumps

There are not many downsides to penis pumps. If used safely and consistently, they will yield great benefits. They are also affordable for most men and can last a long time.

The most common downsides are dependency and the exacerbation of insecurities.

Some men become dependent on the enlargement effects of penis pumps and feel they have to pump every day, or before they have sex to maintain their ego.

Similarly, some men may experience such positive and excited reactions from the women in their lives after they have increased the size of their penis, that it further emphasizes the idea that penis size matters a lot to women. This indicates to men that they may be inadequate if they stop pumping and enlarging their penis, or it may trigger imposter's syndrome that their partners don't actually like them for who they truly are.

Your Mental And Emotional Health

Sex, intimacy, and your penis size are all very complex topics of discussion.

The most important thing is for you to feel good and confident about yourself and your body, and to find a partner who accepts you for who you are.

Your mental and emotional health are paramount to living a full life. If penis pumping can add to your life in a positive and empowering way, then you should start pumping. If you feel that it may impact your well-being in a negative way, it might be best to reconsider whether pumping is right for you.


Final Thoughts: What Does A Penis Pump Do

In our conclusion to "What Does A Penis Pump Do" we will summarize the guide and bring up a few major considerations.

First, we'll look at some penis pump functions and facts, and what it can do for you in the bedroom.

Then, we'll summarize both the positive and negative impact it can have on your self-esteem and life.


A penis pump is a medical vacuum device that creates a pressure around the penis to help treat erectile dysfunction and enlarge the penis.

Penis pumps are used by millions of men around the world to treat erectile dysfunction by helping them get and maintain an erection, and enlarge their penis through consistent and safe pumping sessions.

Penis size is one of the most sensitive and polarizing topics for men as its normally seen as a direct representation of one's masculinity, which couldn't be further from the truth both in the real world and even in the bedroom.

Our society's obsession and addiction to internet pornography has implanted this idea of large penis = great lover in many men's minds, which is false. Does having a large penis help you be a great lover? Of course having a large penis can 100% help you to become a great lover. But being a great lover also encompasses having a strong emotional connection, psychologically stimulating your partner's mind, utilizing other non-penetration methods, and knowing how to use your penis.

Penis pumps will do many things, but simply having a large penis without knowing how to use it and ignoring the emotional and psychological factors will not make you a great lover.

If you approach penis pumps, treating erectile dysfunction, and penis enlargement in a healthy and safe way, you will reap the benefits of having a healthy, functional and larger penis.
