The French male is not noted for modesty when it comes to discussing his sexual prowess, and a survey of condom size appears to underline the point.
More than 10,500 men across 25 European countries were asked to measure their penis - and the French came out on top with a claimed average length of 6.09 in (15.48 cm).
This was 1.2 in (3 cm) longer than the Greeks, who had the shortest average measurement in Europe.
The Frenchman's French letter requirements were disclosed during an eight-month study conducted by the Institute of Condom Consultancy, based in Singen, southern Germany.
Jan Vinzenz Krause, the institute's director, refused to comment on how honest he thought the Frenchmen had been in reporting the data.
The purpose of the survey was to educate teenagers about the importance of effective contraception.
The institute also offers online advice about condom size and hosts "Pimp Your Condom" - an annual fair organised in cooperation with the national Aids Trust - with the aim of informing teens about sexually transmitted diseases.
Krause was in the spotlight in the past when he produced a prototype of the "spray-on condom" - an aerosol can which contains latex that creates a perfectly fitting condom.
However, the idea was not developed further.
