The original Jes-Extender with title "the original penis extender" - The first and best penis enlarger

The Jes-Extender Is the Original Penis Extender

We see permanent penis enlargement as just another way of taking care of your body, in the same way you'd go to the gym, or eat healthy. Why not add something extra in penis size and be the bigger man, literally? We believe the growth in penis size from using Jes-Extender will give you an overall lift in self-confidence, boost your sex life, and improve your overall life satisfaction. To us, penis enlargement is a form of self-improvement. It's no different than going to the gym or using grooming products.

With the Jes-Extender, we deliver a product to you focusing on comfort, ease of use, superior product quality, quick growth results and affordable pricing.

The Jes-Extender Is Backed by Scientific Research

In April of 2011, the British Journal of Urology International (BJUI) published a scientific study, conducted by Italian doctors from the University of Turin. They researched non-invasive penis enlargement, identifying clinically and medically valid research from the field. They researched across various studies to find if any of the results would document proven lasting penis growth.

The findings were conclusive in the sense that various studies on penis traction from different doctors using different methods and trials, all point to the same conclusion. As for all medical research they reviewed, the Turin University doctors point to further evidence being relevant, but not necessary for them to be able to conclude “…"It seems that penile extenders represent the only evidence-based technique of penile elongation". Learn more here about the main conclusions of the study published at BJUI.
