As demonstrated previously,
the average erect penis circumference of western men is 121.67mm +- 13.34mm (4.79in +- 0.53in).
It actually may be significantly lower.
The condom requirements were disclosed during an eight-month study conducted by the Institute of Condom Consultancy, based in Singen, southern Germany. The purpose of the survey was to educate teenagers about the importance of effective contraception.
10 477 men from 25 European Union member countries were therefore surveyed on their penis length and girth.
The European erect penis girth averaged around 117mm (4.61in)
This is slightly below the results from scientific studies. This is surprising as usually the self-reported surveys give significantly higher results. For example the French came out on top with a claimed average girth of 136.3mm. Jan Vinzenz Krause, the institute's director, refused to comment on how honest he thought the Frenchmen had been in reporting the data. Clearly some wishful thinking or even lies were involved in this result.I invite you to follow this very sensitive and funny link:
To conclude, depending on the country and its culture, people may be more or less honest in reporting their actual penis size and if the average ends up below the one from scientific studies, it could reflects that some bias inherent to these studies have been eliminated. One could even say that the true average may be even below 117mm...
This is more tricky. But one could take into account the few scientific studies realised in Asia, which represents at least half the world population.
Here is a chart reporting the main studies in the world concerning the average erect penis circumference (girth):
NB: The different kinds of measurement method (self-report after training, pharmacologically induced erections...) are equivalent as demonstrated brillantly:
- by the Indian study: http://www.nature.com/ijir/journal/v19/n6/fig_tab/3901569t3.html#figure-title
- and by the German study: http://www.ncbi.nlm.nih.gov/pubmed/11182344
The world average erect penis circumference is anywhere between 114 and 118mm (4.49 and 4.65in).
No reliable data from Africa were found. But from the Kinsey data, it appears that the difference between Caucasian and African averages could be neglected.
