From March 11 to 17, 2001 a total 401
males over the age of 18 were measured, one at a time, by qualified
medical staff (protected by Ansell Medi-Touch gloves) in private tents
at the Dady Rock nightclub in Cancun, Mexico. Of the 401 men, 300 were
able to gain an erection for measurement - a success rate of only 75%.
The LifeStyles Condoms Average Penis Size Survey was designed
to create a better condom, to ensure that they are sized properly, comfortable
and won't slip. Are you interested in the different size condoms available?
401 male voluteers of which, only 300 were "effective"
male volunteers (75%), as 101 male volunteers (25%) could not gain an
erection for measurement. At 300 effective measurements, this study
is twice the size of any previous study that uses medical staff to measure
penis size. This method is more accurate and reliable than studies where
volunteers undertake self-measurement / reporting.
Erect Penis Length
The average erect penis length was 5.877 inches (14.928cm).
Standard deviation was 0.825 inches (2.096cm) with 54% of the effective
sample measuring between 5.5 inches (14cm) and 6.3 inches (16cm).
Erect Penis Girth
The average erect penis girth was 4.972 inches (12.63cm).
Standard deviation was 0.508 inches (1.29cm) or with 53.33% of the effective
sample measuring between 4.725 inches (12cm) and 5.118 inches (13cm).
It is fair to say that in all cases, where medical staff
has measured erect penis size, the average length has been below 6 inches
and in every case where the surveys rely on self-measurement and voluntary
reporting the average leaps over six inches. Interestingly average girth
remains around 5 inches in all surveys.
Using the figure of 5.877 inches from the LifeStyles Condoms
Average Penis Size Survey it appears that men on average exaggerate
their penis length by a quarter to a half an inch when they are permitted
to measure and report their own size.
The results do show that the difference between small
penises, average penis size and large penises is not so great as folklore
might have us believe.
