ANSELL RESEARCH

The Penis Size Survey
Ansell, makers of LifeStyles Condoms, has conducted research into average penis size. The survey found that the average length of the erect penis is 5.877 inches (14.928cm), with the majority ranging between the small 5.5 inch penis size (14cm) and the large 6.3 inch penises (16cm).

The average girth is 4.972 inches (12.63cm), with the majority ranging between 4.7 inches (12cm) and 5.1 inches (13cm). This indicates that the difference between small penis size and large is not very big.

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?

Sample Size

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).

Conclusion

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.
