Estimate of Filler Amount Required
Estimate Only
There is variation from patient to patient.
Many patients will achieve more girth than this (and a few potentially less).
Based on measurements provided by approximately 400 patients.

* Swelling can take up to 1 month to disappear completely and may be responsible for some of the initial gain in size.
* For an average length penis, 10ml of filler is estimated to thicken the penis by 10%, slightly less for a longer penis.
How Much Filler To Take
It is better to take less at first.
Less filler is better than having too much filler and needing to dissolve some, which is a waste of time and money.
We prefer patients to gradually increase penis size with multiple visits, rather than to have a large amount of filler in one session.
How Much is One Inch in Penis Girth?
( Quite a lot ! )
To visualise an inch gain in penis thickness.
1. Form a circle with your thumb and index finger.
2. Draw your thumb and index finger apart by an inch.
3. See how much bigger the circle becomes.
An inch increase in girth is very significant on a penis.

Most patients are about 4.0 to 5.25 inches in circumference when erect.
A patient requesting a 2 or 3-inch girth gain probably has unrealistic expectations.
Most patients gain between 0.5 and 1.0 inch
Although some have gained over 2 inches (see Before and After photos).
Gaining over 2 inches in thickness involves significant up-front and ongoing maintenance cost.
See table below for how much filler might be required.
Average Penis Girth (Erect)
It would probably help our sales to suggest that there are many girthy men out there, and play on insecurities.
However, as you can see from the chart below (and numerous other studies), a penis girth over 6.0 inches is extremely rare.
“The average erect penis girth was 4.97 inches.”
“A penis above 6 inches in girth is exceptionally rare.”

For those in a long-term relationship, it is advisable to discuss this procedure with your partner beforehand, to better understand their preferences.
Your partner may be perfectly happy with your current penis size.
If you would like a bigger penis purely as a luxury, Androfill is by far the most sensible medical approach.
