Fellowship Trained Board Certified Reconstructive Urologist

Dr. Cordon

“We’ve been long overdue for something like PhalloFILL® to come to the market. Men have always sought ways to enhance their penis and unfortunately up until now have resorted to things with poor results and/or things that are unsafe. I often have had to treat these patients after they’ve had complications from fillers done elsewhere. I’m excited to finally have something that has been proven to provide great results and can be done safely.”

Board-Certified Urologist and Fellowship Trained Sexual Medicine Expert

AlexTatem PhalloFILL advisory

“Men deserve to feel comfortable and confident in their own skin! Unfortunately, previous options for male enhancement have historically fallen short of the high standards we insist upon for our patients. Hyaluronic acid, however, represents an exciting new paradigm for men and physicians like myself who have dedicated their careers to this field. PhalloFILL is the first commercially available option for cosmetic penile girth enhancement that I’m proud to offer to my patients. PhalloFILL’s combination of meticulous technique and superb filler choice results in unparalleled results for men, time and time again. It’s this reproducibility and reliability that set PhalloFILL apart from every other option on the market. If you’re a man who has always wanted more out of life, I strongly encourage you to consider PhalloFILL”

Board Certified Functional Medicine, Anti-Aging and Regenerative Medicine

Dr. Holly Barko

“The PhalloFILL® enhancement has revolutionized male girth enhancement and made it much safer and more comfortable for the patient. The skillful use of local anesthesia before the injection means excellent patient comfort during the procedure. Having worked in the operating room for many years, I’ve seen everything that can go well or not with surgical procedures and other girth enhancement techniques such as implants or grafting. With the PhalloFILL® enhancement, patients can avoid the associated risks of surgery and general anesthesia, while obtaining a customized girth enhancement and return to normal physical activities much sooner.”

Dr. Barko began to study functional and anti-aging medicine, using an integrative approach that focuses on preventative care and lifestyle changes. She went on to complete a fellowship in Anti-Aging, Metabolic and Functional Medicine and is now board-certified in this specialty.

Board Certified Cosmetic and Reconstructive Surgeon

“In my professional practice it is very common that men ask for genital rejuvenation and improvement of the shape and size of their penis.  Previous methods to enhance the penis involved unreliable results and products that can often lead to complications.  The PhalloFILL® enhancement offers a natural and effective way to enhance penile girth with the most reliable results I’ve seen in male enhancement.  I am excited to introduce PhalloFILL® in Mexico and pleased to have a safe and natural way for men to improve confidence and self perception!”
