SizeGenetics™ PROVEN RESULTS- THE WENDY HURN STUDY

Wendy Hurn, a urology specialist at Bristol Royal Infirmary in the UK, conducted research into treating penile retraction caused by Peyronie’s disease, using the same penis traction method the SizeGenetics™ penis enlarger uses. The study proved that penis traction is a perfect alternative to surgery and is highly effective in not only increasing the size of the penis, but straightening it for men who may be affected by penile curvature and retraction.

The study was based on 22 men between 18-78 years old with Peyronie’s disease. The subjects were divided into two groups; one group of men with 12.5cm or less (stretched penis) and one group of men with over 12.5cm (stretched penis). All subjects wore a medically tested penis enlarger for an average of 5 hours daily for 3 months. At the end of the treatment, Hurn recorded an average 0.8-2.3cm increase in penis length and 20% reduction of penile curvatures.

BJUI RESEARCH

PROVEN PENIS ENLARGEMENT- BJUI RESEARCH
In April of 2011, the British Journal of Urology International (BJUI) published a scientific study, conducted by two Italian doctors from the University of Turin. They researched in the field of non-invasive penis enlargement, identifying clinically and medically valid research that had already been published. The aim was to bring all of the research in the field together, to finally draw a conclusion as to which penis enlargement methods could really be proven to give lasting penis growth results.

The below texts are extracts from the study, which show that the penis traction method of penis enlargement that Jes Extender uses is the only proven method to give natural, safe and permanent growth to the penis.

1,5 inch (3,8 cm) in 5 month

I’ve been using it 5 hours a day for the last five months. It was 5″ when I started – now it is 6.5″ and still growing. My erections are stronger, harder, longer lasting and my orgasms and ejaculations are now more intense. Very satisfied!
