Jelqing is a hotly-debated topic in the penis enlargement community.

Some say this penis exercise can enlarge size - some say it doesn't.

In this report, we're going to show the before and after pictures of men and the numerical data on Jelqing Results.

(Or if you simply don't have time to jelq - you might want to utilize the PhalloGauge Extender instead, which trains your penis automatically so you don't have to.)

7 Male Subject Jelqing Exercise Study 2018

Size study completed September 30, 2018

We were able to sign-up 8 male subjects who were willing to help us discover whether jelqing exercises are, in fact, an effective penis enlargement technique.

The amount of penis size gained was quite revealing.

The Experimental Setup (How)

  • 8 men between the ages of 25 and 40.

  • To keep it simple, each man was required to enlarge and do a 200 jelq stroke exercise jelqing session every day for 3 months.

  • Each subject was required to tally each jelq stroke on paper to make sure that the stroke count was as accuate as possible. These jelq tallies were returned back to me.

  • Each male used the same water-based penis lubricant that I administered.

  • One subject dropped out in the middle of the penis study - so I have only reported the jelqing results of the 7 men that completed the study and completely ignored the drop out's data.

  • Each subject came to my office for a penis measurement every two weeks.

  • Each penis measurement appointment consisted of only erect length and erect girth.

How Each Jelq Measurement was Taken

You might be wondering how I personally took each jelqing result measurement.

I did not ever.

The reason being was because I know that sexual arousal could affect the jelqing exercise enlargement results measurement, so I thought it would be best for each man to take his measurement.

Therefore, I did not want to corrupt the jelqing results because I wanted to make sure that each man was at a maximum enlarge erection level.

So when one subject came to the office, they went into a seperate room which had a camera setup.

Each subject was instructed to enlarge to their maximum erection hardness size.

My reasoning is that every guy knows how big they can fully get, so I left it to their discretion.

Each subject was trained on how to measure their penis size using the measuring technique described here.

The camera was aimed down and filmed each subject doing both an erect length and erect girth measurement.

The camera was only zoomed in on the penis so their identity was perfectly concealed.

I would then take the recorded video data and watch it to see if they did the jelqing results measurement correctly.

If so, I would add that measurement to the master data set.

Study Conclusion and Discussion

The clear conclusion is that jelqing exercise does not have a significant effect on erect penis size enlargement.

There were little to none enhancement in penis length gains.

There were minor penis girth gains in some subjects, but nothing big.

There does seem to be a very weak positive natural trend in size, however, due to the timeframe of the study, we cannot conclude if it is linear or asymptotic.

What we did not explore was the post 3 month (13 week) period.

Additionally, the penis enlargement variance in of all the subject's results does not provide a positive trendline to suggest that jelqing exercise results are conclusive.

Additionally for subjects who did experience a small increase in size, it would be hard to justify and prescribe the jelqing method as a worthwhile therapy for enlargement, given the time and energy it required.

Our study only looked at the "Jelqing" exercise technique, so our conclusions are based on it.

I look forward to anyone fellow doctor who can reproduce results.

So is jelqing the best penis enlargement technique?

Unfortunately no.

According to many independent clinical studies and medical reports, the best technique has always consistently been the penis extender device.

Fortunately, our lab has invented the perfect solution: PhalloGauge Extender device.

What to Expect

So there's good news and bad news.

The bad news:

One can typcially expect to gain:

  • Up to 0.5 inches in girth (that's decent)

  • 0.2 inch in length (that's little)

This is over the course of 4 to 6 months, with one 10-20 minute jelqing session each day.

Other notable universities, like University of California, Santa Barbara, have also reported on jelqing.

Alternative Methods

And length gains? Not so great...

But the good news: There's much better options out there than jelqing for size.

If you really want to gain length (and much faster), then you should consider devices that utilize penis traction (highly recommended).

Why? Well the results have already been documented and proven in clinical results..

Or you could do all the different penis exercises.

Looking for the best girth gains?

And if you're willing to spend some money for a much better girth result - you should consider using a penis pump instead.

In fact, pumps were a device used in the clinical study by the Journal of Sexual Medicine.

But I want an easy way to train my penis automatically!

Nobody has time to do jelqing for an hour each day.

But there's a special device that can train (stretch) your penis automatically.

It's our 100%-safe, clinically-approved device we designed for easy penile lengthening.

Before and After Pictures

Unfortunately, all before and after pictures from our study are only provided to our subscribers. Apologies for the inconvenience.

Most men who truly want penis enlargement, will jelq.

Here are the commonly claimed jelqing results:

  1. What jelqing primarily targets are girth size gains (not length). Women prefer girth for pleasure over length.

  2. Minor jelqing result length gains can be observed due to the pulling-nature of the exercise.

  3. It provides stronger, fuller, healthier erections.

  4. It promotes delivery of nutrient-rich blood to all of your penile tissues, which is also directly responsible for cell hyperplasia and penis traction.

  5. An example of cell hyperplasia in the penis.
    More cell mass means more size. Jelqing is a technique to accomplish this.

Reasons Why Jelqing May Work

You'll notice that the men who served as my 7 subjects in the study added a small amount of natural jelqing result size.

Here are my scientifc hypotheses on why the jelqing exercise may work a little for penis enlargement.

Jelqing exercise works because it uses the positive pressure from your OK-grip to pump blood into your Corpora Cavernosa in the shaft of your penis.

What works like this? A penis pump.

Think what happens to size when you squeeze a semi-inflated balloon.

How the penile tissues are "trained" - like squeezing a balloon.

If you squeeze one side, then all the air will be pushed into the other side and the balloon will get large.

Now take this analogy and apply it to the jelq on your penis.

Now, instead of air causing a balloon surface to expand outward, it's blood pushing outwards on your penile tissues!

The penis gets large - this is how natural penis enhancement girth gains appear.


Jelqing is one of the basic exercises out of all penis enlargement techniques, and is safer compared to surgery, according to the U.S. National Library of Medicine.

Not only that, but the "jelq" is probably the best, easiest exercise to get started with.

However penis pumps better options for girth gains.
