Abstract
OBJECTIVE:
The knowledge of normal variations in the size of male external genitalia is of considerable interest to several disciplines. We carried out an extensive study in young Italian males to provide estimates of normal variations of penile dimensions.
METHODS:
The penile length in flaccid and stretched states and the penile circumference were measured in a random group of 3,300 young men aged 17-19 years and free from endocrine disorders and from congenital or acquired abnormalities of the penis. In a random sample of 325 subjects of the same set of people, penile length and circumference were also correlated with weight and height. Statistical analysis was performed with the Sperman test, because our data were not normally distributed as tested by the Kolmogorov-Smirnov test (p < 0.01).
RESULTS:
The median values of penile dimensions recorded in the present study are flaccid length 9.0 cm, flaccid circumference, at the middle of the shaft, 10.0 cm, and stretched length 12.5 cm. We also observed that the penile dimensions are highly correlated with height and weight.
CONCLUSIONS:
Since penile length and circumference correlate with anthropometric parameters such as weight and height, we suggest to consider themselves as two bodily measures which display a wide extent of normal variability along the general population.
Absolute fucking rubbish. How people get paid to come out with this shite...they should consider themselves lucky, put it that way.
Sample size far too small to draw any wide-reaching conclusions. Sample size related to weight and height is completely worthless. No causality tested at all, it's just yet another correlative study.
Furthermore, look at the bolded part. Every single previous study that I've ever seen on this subject concludes that average penis size is close to 6". There's a study here:

Wikipedia states with regard to this:
A review published in the 2007 issue of BJU International showed the average erect penis length to be 14–16 cm (5.5–6.3 in) and girth to be 12–13 cm (4.7–5.1 in). The paper compared results of twelve studies conducted on different populations in several countries.
There are several other recent studies that all conclude the average is higher than in the Italian study.
So I think, so to speak, we can put that one to bed, University of Florence. Thanks for your contribution to 'science', though.
