Yet, only a few brands thrive in the market because of the quality they provide in exchange for money their customers pay.

But are penis extenders safe?  Let us explore that in this article and see for ourselves what makes this device different from other enhancement products.

What exactly is a penis extender, and how do they work?

Penis extender

A penis extender is a traction device used to increase the size of the penis. It is a mechanical device that delivers a constant stretch on the penis shaft.

Usually, a penis extender is worn for hours every day, which results in microscopic tears on the tissue.

These microtears, when healed through the process of cytokinesis (cell division), results in the addition of extra cell mass, which over time becomes size increment.

On an average, 0.5 inches ~ 2 inches of the size difference is seen while using a penis extender for 5 ~ 8 months.

In some cases, this size gain goes up to 3 inches, which is purely dependent upon the individual body.

After wearing the device, the inbuilt spring or screw system will start stretching the shaft of the penis, and this process is kept as such for 4 ~ 12 hours a day.

There are several accessories with extenders, which makes the stretching process painless and comfortable.

Are penis extenders safe to use?

Without a doubt. Penis extenders are 100% safe if you use it correctly, as recommended by the manufacturer or doctor.

First of all, there are no medications you need to take along with a penis extender unless prescribed by your doctor.

Second of all, this is just a mechanical device that is worn over the penis and is made from medical grade plastic and stainless steel/aluminum.

Your penis is simply stretched under a safe, constant tension and retained in that state for some time to induce controlled micro-tears on the penile tissue.

These injuries are painless and would not cause any harm to the user. It is more or less like building muscle in the gym (the mechanism is the same).

You are giving some workout to your penile tissue to create micro damages, which, when healed, will provide you extra cell mass.

Here the figures (tension of spring, the time required, length of the base, the thickness of comfort pads, etc.)  are all scientifically studied and established, so all your worries can be dismissed.

What are some of the safety features in a penis extender?

There are lots of safety features included in modern-day penis extenders, of which some are mandatorily recommended by the medical associations or approving agencies.

Comfort pads are the most critical feature that protects the penile tissue from abrasions when held under tension.

These are usually skin friendly Styrofoam tapes that are stuck to the skin region that make contacts with penis extenders.

The cutoff is a unique mechanism that would prevent a spring or screw system from increasing the tension load beyond a particular value. In most penis extenders, this limit is set to 4000g or 4500g force.

A strap-on belt is another safety feature that ensures the penis is securely held onto the pubic region to prevent wiggling.

Some of the penis extender brands might give you a condom sleeve to protect the surface skin of the penis.

The lightweight aluminum frame is the most preferred choice for construction as it is durable, safe, and skin-friendly.
