What Causes Kidney Failure?
20 August 2026Penis enlargement exercises are practices based on manual stretching, massage, or mechanical traction, performed with the aim of increasing penile length or girth. On the internet, methods such as jelqing, manual penile stretching, and penile pulling exercises are commonly recommended.
However, there is an important scientific distinction: there is insufficient scientific evidence showing that manually performed penis enlargement exercises can permanently increase penile length or girth. In contrast, there is scientific evidence suggesting that penile traction devices, which provide controlled and prolonged stretching,
What Are Penis Enlargement Exercises?
The methods used or promoted online for penis enlargement differ considerably in terms of the scientific evidence supporting them.
| Method | Does It Increase Penile Size? | Scientific Evidence | Main Risk / Limitation |
|---|---|---|---|
| Jelqing | Not proven | Insufficient | Pain, trauma, deformity |
| Manual stretching/pulling | Permanent increase has not been proven | Insufficient | Tissue and vascular damage |
| Kegel exercises | No | No evidence for enlargement | Does not increase penile size |
| Vacuum erection device (VED) | May provide temporary enlargement | Limited | Bruising, pain, trauma if used incorrectly |
| Penile traction device | Yes, to a limited extent | Moderate | Pain, numbness, bruising |
1-)What Is Jelqing?
Jelqing is a penis enlargement exercise based on rhythmically squeezing, massaging, and stretching the penile tissue by hand. It is generally performed using repeated movements from the base of the penis toward the tip. The main claim is that these movements may gradually cause the penile tissue to expand and lengthen over time.
However, there is insufficient clinical evidence to support this claim.
The 2026 ICSM report states that reported increases in penile length with jelqing are largely based on self-reported outcomes and that there is no scientific evidence demonstrating its true clinical effectiveness.
Does Jelqing Increase Penis Size?
Jelqing has not been scientifically shown to permanently enlarge the penis.
Following the practice, increased blood flow may temporarily make the penis appear fuller or larger. However, this does not represent permanent tissue growth, and studies specifically emphasize that any enlargement reported with jelqing is likely to be temporary.
Is Jelqing Harmful?
Jelqing is not completely risk-free. Applying excessive force may cause trauma to the penile tissues.
Scientific reports have described penile injuries and penile deformity following jelqing and similar aggressive manual techniques.
For this reason, intensive or aggressive jelqing programmes described online should not be performed without medical supervision.
2-)Do Penile Stretching and Pulling Exercises Work?
There is insufficient scientific evidence that manually pulling or stretching the penis for certain periods can produce permanent penile lengthening.
It is important to distinguish manual stretching from penile traction therapy.
Traction devices are medical devices developed to apply a specific and controlled stretching force to the penis over a prolonged period. They are not the same as manual stretching exercises performed for a few minutes.
3-)Do Penile Traction Devices Work?
Penile traction is one of the non-surgical penile lengthening methods with the strongest scientific support.
Some studies have reported increases of approximately 1–3 cm in penile length after daily use for 4–6 hours for at least 3 months. However, the quality of the studies and the types of devices used vary.
Side effects associated with traction are generally mild. Reported adverse effects include pain, numbness, and bruising. In studies, approximately 10% of patients discontinued treatment because of inadequate results, difficulty using the device, or side effects.

4-)Do Vacuum Pumps Increase Penis Size?
A vacuum pump can temporarily increase penile length and girth by drawing more blood into the penis during use. However, there is no strong scientific evidence supporting vacuum devices as a method of permanent penis enlargement.
Vacuum devices have been reported to affect penile girth more noticeably than length. One of their better-established medical uses is penile rehabilitation after prostate surgery, where they may be used to help preserve penile tissue and erectile function.
It should also be remembered that not every vacuum or traction device available commercially has undergone clinical testing. The ICSM report emphasizes that a significant proportion of commercially marketed devices have not been subjected to comprehensive scientific evaluation.
5-)Do Kegel Exercises Increase Penis Size?
No. There is no scientific evidence showing that Kegel exercises permanently increase penile length or girth.
Kegel exercises strengthen the pelvic floor muscles and should therefore be considered separately from penis enlargement exercises.
Strengthening the pelvic floor muscles may contribute to better erection control and sexual function in some men, but this does not mean that the penis becomes anatomically larger.
Are There Exercises to Increase Penile Girth?
There is no manual exercise that has been proven to permanently increase penile girth. Although jelqing and similar massage techniques are claimed to increase penile thickness, the scientific evidence is insufficient.
Vacuum devices can produce temporary penile expansion during use, and studies suggest that vacuum therapy may have a more noticeable effect on girth than on length. However, this is not the same as permanent penile girth enhancement. For patients seeking permanent or longer-lasting penile girth enhancement, alternatives to exercise include hyaluronic acid fillers, fat injection, and various surgical techniques. However, the effectiveness and risks of these methods should be evaluated individually.
The ICSM considers methods such as hyaluronic acid and autologous fat among relatively safe options, while noting that repeat procedures may be required over time.
What Is the Most Effective Method for Penis Enlargement?
Among exercises, there is no manual method that has been strongly proven to provide permanent penile enlargement.
For men seeking to increase penile length, penile traction devices are among the non-surgical options with the greatest scientific support.
For patients seeking an increase in penile girth, fillers and other medical or surgical options may be considered. The most appropriate method should be determined according to current penile measurements, expectations, erectile function, and physical examination findings.
It is also important to obtain an accurate penile measurement before considering treatment in a man who is concerned about penis size. This is because conditions such as micropenis, buried penis, and the perception that a normal-sized penis is too small need to be distinguished from one another.
Scientific evidence also recommends accurate measurement of penile length and girth before treatment.
