Penis Stretcher vs. Penis Pumps : Side-by-Side Comparison

One of the most acknowledged techniques for penis enlargement is the use of enlarging devices. These devices can be categorized into one of two types: penis stretchers and pumps, each having its pros and cons.

The following chart compares a typical best rated penis extender (aka penile traction device, aka penis stretcher) and a typical best reviewed penis pump by Bathmate, discussing the advantages and disadvantages of each.

Please note that the featured penis pump is water-based and not the classic air pump. Hydraulic penis pumps are the latest hype in the natural male enhancement world. They work similar to air vacuum pumps, but are considerably safer.

What is it? A medical device that implements the long-proven technique of stretching (traction force) to promote growth in penile tissue. A special tool (hollow tube) that uses vacuum pressure to force the penis to expand and become bigger.
What does it do? Promotes permanent penis enlargement and helps increase penis length. Also helps correct penile curvatures. Helps men with erectile dysfunction get a rigid, full erection temporarily. Also used to permanently increase penis girth (thickness) with regular pumping.
How does it work? By applying constant traction force on the penis, which ultimately makes the cells of penile tissue multiply, and thus the penis grows longer. By creating a vacuum area around the penis, which then sucks the penis into a fitting tube forcing it to enlarge to its maximum size. The blood flowing in causes a full, strong erection.
Is it easy & comfortable to use? The device is very small and pliable and can be worn under one’s (loose) pants without being uncomfortably felt by the user, or noticed by others. It takes practice and patience until you can wear it conveniently. Very simple and fast to use according to the provided instructions. With water-based pumps, you can use it while taking a bath or shower.
How big are gains? In a clinical trial, the maximum reported gain in size resulting from regular use of a penis stretcher was about 1 inch increase in length. On average, most users noticed improvement in length, but no change in width (girth). Studies have shown that pumps can (temporarily) add about half an inch to penile length and width. Long term use can also result in permanent growth.
Does it last? Gains in size are long-lasting and often permanent. The erection boost lasts for a few hours at best. Permanent enlargement is possible with frequent use.
How fast does it work? The user should expect to notice results gradually after a few months of usage. Optimum results may take about a year to achieve. Takes only a few minutes to get an “assisted” erection. Using it every day or so for a few months can also add some permanent gains, especially to your girth.
Safety: Proper use (as instructed by the manufacturer) has proved to be safe and comfortable. Improper use/overuse may cause serious damage to your internal penile structure. Water-based pumps are quite safe and risk-free when used as instructed. Air pumps are more risky and may cause bursting of blood vessels or erectile dysfunction.
Cost: Not really cheap. A decent penis extender device can cost anywhere from $200 to $400 USD, or even higher with extra functionalities. However, considering the results one would expect from such a product, it can be justifiably described as cost-effective. The average cost ranges from $50 to $200. Depends on the type of pump and its specifications.
Recommended product: The Original Jes-Extender is one of the best devices. Top quality and reputable company. Bathmate Penis Pump is a powerful water-based pump. Pricey, but works well.


The Science Behind Penile Stretcher Devices

Basic penis stretcher deviceEvery other male yearns to add length and girth to his penis. To this end, penile stretcher devices have caught the imagination of an average male like no other modes of penis enlargement. The hype seems justified to some extent primarily due to the backing of scientific community.

How Do Penile Stretcher Devices Work?

Penile stretcher devices work on the scientific principle of traction to deliver long and hard penis. The idea is to apply sustained pressure to penile tissues so that they break down, multiply and grow naturally.

The principle of traction is used in the treatment of different orthopedic ailments where pressure is applied in the form of traction in order to enlarge the ends of human bones and phalanges. The use of traction is also widely prevalent in different cultures to elongate several body parts. For instance, the “long-neck women” of the Padaung hill-tribe in Myanmar are famous for their long and slender necks due to brass rings worn around their necks right from the young age of 5-6 years.

The penile stretcher devices too work on the principle of traction, i.e. sustained pressure on the penis, which results in the breaking downmultiplication and reproduction of several penile cells leading up to length and girth gains. Simultaneously, internal cavities of the penis are also forced to expand. This allows the flow of more blood in the penile region, and this continuous process makes the changes permanent; thus, leading to a long lasting increase in overall size. The increased blood circulation to the penis means improved and stronger erections that can be sustained for a longer period of time, giving ample sexual stamina to make the blissful moments with your partner last much longer.

In fact, an analogy can be drawn between a weight trainer lifting the weights and a man applying traction based pressure to break the cells and allow them to multiple and give length and girth gains.

Scientific Evidence Behind the Working of Penile Stretcher Devices

A popular clinical study [PDF], the results of which were published in the British Journal of Urology in March 2009, concluded that the sustained use of penile stretcher devices indeed resulted in significant length and girth gains. In this study, a traction based device was used by the subjects for 5-6 hours daily for a period of 6 months. The results were positive without any side effect.

Not just penis enlargement, the traction based devices are also beneficial in treating Peyronie’s disease (penile curvature) as established by the study published in the Journal of Sexual Medicine in 2008.

Several studies have gone into the details and specifics of length and girth gains by the use of penile stretcher devices, and almost every study has reported that traction definitely helps in increasing the penis size and girth. However, the exact gains are dependent on the individual’s response to the traction pressure. Moreover, the studies are also unanimous in their opinion that the longer the use of penile stretcher devices the more significant the results will be.
