How does the SizeGenetics Extender work?

How does SizeGenetics work

SizeGenetics device works by the principle of penis traction and most the penis extenders work using the same technique and elongation bars.

But SizeGenetics is way out if the league due to their unmatched design profile showering comfort, efficiency, and utility compared to other market competitors.

So to understand the working you must know how bodybuilders using the same technique to buff up.

When a constant load of tension or work is given to any muscle in our body, the tissue cells get expanded resulting in micro tears. However, the device has a good comfort system.

The body immunity will soon kick in and start with the healing process, like paving blocks to grow a road, but here in the middle.

The cells around the tear actively divide and release chemical messengers to bring in more supplies and thus once it heals there is an increase in cell mass.

When you do this on a daily basis the repair and tearing process go simultaneous resulting in a gradual buildup of mass, finally resulting in increased size.

With mechanical guides on the SizeGenetics, the curvature is also corrected since the healthy posture is maintained parallel to cell growth.

What results can you expect?

sizegenetics package

The SizeGenetics extender is a sheer engineered marvel and would deliver the promised result; all you have to do is use it as prescribed by the manufacturer of your doctor.

In all clinical studies, the researchers have seen that constant traction of 2800gm was enough to induce micro tears and associated cell proliferation.

So you could expect a size change within a few weeks of usage, 3 -4 weeks minimum.

From their study, it was seen that a 15% increment was seen within 8 weeks of usage which increased to 19% in 16 weeks, 24% in 20 weeks and 30% increase within a span of 24 weeks.

Also, SizeGenetics system is a type 1 medical device used for fixing the incurvate penis caused due to Peyronie’s disease3.

Not limited to a single physiotherapeutic application, but SizeGenetics has been extensively used by doctors to address various anatomical anomalies with a penis.

Are SizeGenetics results permanent?

SizeGenetics penis size

Yes, the results can be permanent provided there are some level physical activities happening to the penis tissue.

All the results you achieved with SizeGenetics would stay with you even if the product use is discontinued

The same principles of muscle building can be borrowed to demonstrate the idea here.

One thing to note is that penis tissues might change over time resulting in slight variation but not any major size difference.

Some of the medical conditions can lead to penis shrinkage, but apart from that, the increased penis size will be permanent.

As long as the cytokinesis of penis cells happens the size you have gained will be maintained.

The traction induced growth is a physical process thus change is also physical and would stay, unlike the chemical induced penis size increment.

SizeGenetics reviews

SizeGenetics extender

The overall customer satisfaction index scored 89% for SizeGenetics after taking into account various factors like value for money, user reviews, satisfied customers, the onset of action, etc.

Some of the user reviews grabbed from the internet indeed suggest that SizeGenetics is a reliable product.

Pe doc mentioned on mensreviewzone as:

After 3 months of use, I noticed that my “member” has grown 1cm longer. But the device never failed me over months of use. Now, I have 13.9 cm in length. But my goal is to lengthen my circumcised penis up to 15.6 cm.

Banana Bender added his comment on as:

I added about 2cm using the SG, in fact, I’ve used two other high-quality extenders towards the end. Personally, I think all of them worked. But you have to take a great deal of care with them so that they do not cut off blood supply to the head. Looking at SG I think it is quite good and comparable with other ones I was using.

Mizik commented on a SizeGenetics review video as:

Been using the SG device since 2009. I use to be 5 and a half and now I’m 7 half. I can say it really does work.

Since it is endorsed and backed by medical professionals, it is safe to call this a positive product.

Not all individual would experience an equal size increment; with varying physiology and genetics, the size increment also changes.

So overall this is a genuine and effective product to increase the penis length by 1 ~ 2 inches on average.
