Berlin - A study has found that the standard EU size of condom is often too big for German men, a magazine reported yesterday. Focus magazine said a study by a leading German condom manufacturer, Condomi, found standard-sized condoms falling off half of the men studied. "The average German penis is about 3.5mm to 4mm (0.13" to 0.15") too narrow for the standard EN 600 condom," the magazine wrote. The EU set the EN 600 guidelines for rubber condoms in 1996 to establish a uniform standard across Europe.
