A WW2 song claimed Hitler only had one testicle — and a report just proved it to be true

It appears the notorious wartime song may have been right all along. New evidence has emerged that Adolf Hitler really did suffer from an undescended testicle.

Ever since British soldiers started singing “Hitler has only got one ball” to the tune of Colonel Bogey, debate has raged over whether there is any truth to the assertion that Hitler was missing a vital appendage.

Now a German historian claims to have discovered incontrovertible proof. In 1923, Hitler was examined by a prison doctor after his arrest following the failure of the Munich Beer Hall Putsch.

Medical records clearly show that Hitler had an undescended testicle on the right side, according to Prof Peter Fleischmann of Erlangen-Nuremberg University. The records were lost for decades before resurfacing in 2010, when they were confiscated by the Bavarian authorities. They have only now been studied properly.

The findings appear to contradict earlier reports that Hitler lost a testicle to shrapnel in the First World War. The Soviet autopsy carried out on Hitler’s remains in 1945 listed that one testicle was missing — although, curiously, it recorded the left as being absent.

The popular song emerged in 1939 and is thought to have been written by a publicist for the British Council, which was tasked with helping build propaganda that would damage the Nazis.

The commonly-recalled version is an adaptation of the original, which ran: “Göring has only got one ball, Hitler’s [are] so very small, Himmler’s so very similar, And Goebbels has no balls at all.”
