Are these fillers worth it?

I have written a few papers about penis enlargement, augmentation phalloplasty, and evidence-based outcomes. Safety is always the priority. Here are some links to the papers:
Penis enlargement surgery can offer modest improvements in both length and girth, but there are risks and limitations that should be carefully considered. Always go to an experienced provider. Complications can be devastating.
Lengthening Surgery: The most common method involves cutting the suspensory ligament that attaches the penis to the pubic bone, which can result in an increase of about 1 inch in flaccid length. However, this may not significantly affect erect length. Additionally, some men experience a "drooping" effect where the penis no longer rises in erection, but instead points downward.
Girth Enhancement: This can be achieved through fat grafting (using the patient’s own fat) or the insertion of dermal fillers or collagen-based materials. These techniques can add circumference, though fat grafts may have issues with uneven absorption, and synthetic fillers can lead to complications like infection, ulceration, or extrusion. The use of Alloderm (a type of cadaveric tissue) has been controversial due to risks of tissue reabsorption or complications.
Minimally Invasive Alternatives: Non-surgical treatments, like platelet-rich plasma (PRP) injections or fillers, are also options for improving penis girth and overall appearance. These methods generally have shorter recovery times and lower complication risks compared to surgery. Fillers tend to increase girth, and increase flaccid length minimally due to the extra weight.
While surgery can lead to some visible improvements, the results may not meet all expectations, and the risks of complications are significant. For those seeking a modest increase in size, non-surgical options may offer safer alternatives. Consulting with an experienced surgeon is essential to determine the best course of action.

Hi thanks for asking this question. First of all we need to make sure you are measuring your penis correctly. The standard way of measuring is to stretch the penis as far as it will go and measure from the base to the tip of the head. The average stretched length is about 5 1/4 inches. To meet the medical definition of a "micro penis" the stretched length would need to be less than 3 inches. If you are measuring correctly your measurements definitely do not classify you as having a micro penis and fall within the normal range. Dermal fillers do not increase the erect length of the penis, they can only help increase the girth and make the flacid penis look longer. There are some risks to penile fillers including lumps, nodules and decreased sensitivity and if not performed correctly, it could lead to permanent disfigurement and erectile dysfunction. This is not a procedure I would recommend for someone at your age. I usually turn away patients who are so young and do not have an actual micro penis. However, If you feel you do need to do something and want to get a treatment that is less risky and more natural there is now a treatment protocol available called "P-Long" this treatment involves using a vacuum pump and a stretching device along with injections of platelet rich plasma. This protocol does involve a daily routine that you would need to do and could be a significant financial investment for a young person, but the cost is less than having filler injections. (I absolutely would not recommend suspensory ligament ligation or implant surgery in case you were thinking of those procedures). Go with the P-Long or just be reassured that your measurements are quite normal and you don't need to do anything.
