Doctor Approved and Clinically Tested

Not only was the Jes-Extender invented by a leading plastic surgeon specialising in penis enlargement surgery but it has been clinically tested to increase penis size and help correct penile curvature (Peyronies Disease).

For these reasons it has worldwide recognition amongst Urologists and Plastic Surgeons.

This medical background means that the  Jes-Extender has full approval for personal use without the intervention of a doctor - natural, painless, safe and permanent enlargement in your own home!

Please read on to find out about the medical company behind the Jes-Extender, the plastic surgeon who invented it and the clinical study that proves outright that the Jes-Extender works!

DanaMedic was founded in 1994 by a small group of Danish plastic surgeons headed up by Dr. Finn W. Knudsen. At that time they had finalized the development of Jes-Extender which took a year and a half. 

The surgeons observed that after penile elongation surgery the patients sometimes suffered with retraction and later the build up of scar tissue. The Jes-Extender quickly proved to prevent these unwanted side effects, and furthermore increased the total gains from the incision substantially. 

In one of their tests they included a group of men that hadn't undergone surgery as a control group, and discovered that they as well got a noticeable increase of both penis length and girth. 

The Jes-Extender was further developed to become a "self use" product, apart from the original use as post operational treatment. All the designs, production and assembly take place in Denmark. 

The inventor Dr Jorn Ege Siana (M.D., I.A.M.S.S., A.S.P.R.S.)

Jorn Ege Siana, M.D., who is a certified specialist in General - and Plastic surgery in Denmark, Germany and Sweden worked out the principles underlying the Original Jes-Extender. Doctor Siana has since enjoyed international recognition as a leading expert within the field of both surgical and non-surgical penile lengthening since 1993. His expertise has ensured that the Jes-Extender is accepted and used by Urologists and Plastic Surgeons in 29 countries.

FACT: Dr Siana set a world record for the world's longest penis extension. The penis was first surgically extended and then the Jes-Extender was applied to extend the penis a full 14.5 cm (5.7 inches).

What Dr Brian Richards MD has to say about the Jes-Extender

Doctor Brian Richards is the author of "The Penis" and over 25 other books. As well as being the MD of the Kent Private Clinic, he is an expert in Regenerative Therapy and was on the Consultant Panel of the British Journal of Sexual Medicine during it's early years. He is one of the very few doctors to have conducted real research and trials into non-surgical penis enlargement. 

Dr Richards has this to say about the Jes-Extender: "The Jes-Extender is a marvel of precision engineering and has produced outstanding results in lengthening the penis and also correcting penile curvature (Peyronie's Disease). "

The Clinical study

Tractive Elongation of the Penis by Means of Stretching
Study presented at the 1st International Interdisciplinary Symposium on Genitourinary Reconstructive Surgery.

April 6th, 7th and 8th 1998 - Barcelona - Spain

Introduction

Based on the evidence of human tissue response to stretching a traction device for non-invasive penile lengthening has been designed: The Jes-Extender.

Average increase in % with 18 test persons

 

Penis enlargement traction device

• Basal  ring, fastened proximally around the root of the penis, abutting on the symphysis.
• Two dynamic metal bars hinged to the ring, connecting it to the silicon-support, fastened around the corona glans at the distal end of the penis.
• By gradually increasing the tractive force on the two metal bars a stretching force is exerted on the corporae of a 600-1500 g.

Material and methods

• Number of patients: 18 patients ranging from 23-47 years
• Inclusion: normal erectile capacity and no penile surgery
• Exclusion: chronically diseases
• Traction force: 0- 2 weeks - 900-1000 g 2-24 weeks - 1000-1200 g
• Treatment period: 12 hours daily 7 days a week 8 to 24 weeks
• Follow up: every 2.week

	Weeks	Length before	Length after	Difference	Length %
Mean	18.0	11.2 cm	13.9 cm	2.7 cm	24.0
Range	8.0-24.0	8.5-13.5 cm	9.5-18.5 cm	1.0-5.0 cm	12.0-42.0

Conclusions

The average result of Jes-Extender treatment was an increase in erect length of 2,8 cm (1.1 Inch) after 1100 hours at 1200 g traction force. The corresponding flaccid increase is 1,9 cm or 0.75 inch.

• Preliminary study
• All patients achieved penile lengthening after traction with the Jes-Extender
• Average lengthening per week was 1,9 mm
• No complications
• Medical indications

a) Non-invasive: hypoplasic penis, Peyronie's disease
b) Postoperative: hypospadias / epispadias, penile lengthening procedures

Clinically proven enlargement in the comfort of your home
