Having qualified with a medical doctor qualification at the University of Copenhagen medical school in 1983, Dr Siana has gone on to be one of the worlds leading professionals in the field of plastic and general surgery.

Initially developed as an aide to the development and healing of the penis after surgery has taken place, Dr Siana quickly recognized the benefits that existed from using the device for penis enlargement alongside his surgery.


Eager to prove that the device was more than just a tool for healing, Dr Siana began clinical testing.

Read about his inital studies here:
Non-Surgical Penile Elongation
Surgical Penile Enlargement Elongation and thickening
Combination of surgical lengthening and postoperative penile traction
Peyronie’s Disease and Hypospadias

This helped to prove that the device was also able to produce the desired results and straighten out curvatures, regardless of whether the patient had received surgery or not.

Following these excellent results the SizeGenetics™ device has been used by thousands of clinics across the world as part of their methods to help their cause

As a qualified and practicing plastic surgeon my work often involves working with men who are insecure about their penis.

These men will often ask if surgery is the answer, in some cases it is but I will always recommend alternative methods to be used instead of or alongside surgery.

One of the methods I recommend is the use of a traction device, more specifically the SizeGenetics™ traction device. This is the only device I trust as a clinically tested medical type 1 device able to help:

  • Extend the penis by inches
  • Reduce and remove penis curvatures

Sometimes men will ask me if there is a cheaper device available. I tell them that whilst there are lower cost extenders available, these are often not clinically proven and usually made from inferior materials that can put your health at risk.

SizeGenetics™ is the only device I can confidently recommend as I know the device is made 100% from medical grade components and is therefore safe.

What’s more, through both my patients and the study data available, I also know that SizeGenetics™ can be extremely effective.

My patients have reported some excellent results not only in terms of their extension gains but also in straightening out curvatures. It is for this reason that I give SizeGenetics™ my full backing as a safe and effective, medically endorsed method for improving the penis.
