It has long been suspected that Hitler’s conquest of Europe was an attempt to compensate for a lack of potency elsewhere.
But the notorious playground rhyme about his testicles appears to have only told half the story, as a book claims the leader of the Third Reich had a micropenis.
In their book Hitler’s Last Day: Minute by Minute, they say they have uncovered medical records which confirm the Fuhrer’s embarrassing deformity.
The condition is so severe that sufferers have to urinate from a hole at the base of the shaft, instead of the tip.
It comes just two months after a German historian said he had found proof that Hitler really did have one testicle, as per the famous 1939 playground ditty.
“Hitler himself is believed to have had two forms of genital abnormality: an undescended testicle and a rare condition called penile hypospadias in which the urethra opens on the under side of the penis,” Mr Mayo and Ms Craigie wrote.
The discovery could offer some explanation as to why Hitler was allegedly afraid of being seen naked and the cause of his famed fits of rage.
It also likely to add fuel to the debate on Hitler’s sex life – or lack thereof – which is fiercely contested by historians.
In his biography of Hitler, the British historian Ian Kershaw said the Austrian-born Nazi leader was repelled by sexual activity of any kind as he feared catching an infection.
However, there is evidence he had romantic encounters with a series of women in his lifetime, including his mistress Eva Braun, with whom he committed suicide on April 30, 1945. One German biographer, Heike Görtemaker, has insisted that the couple enjoyed a happy and healthy sex life.
Hitler’s personal doctor, Theodor Morell, is also said to have diagnosed the Fuhrer with hypospadias and had prescribed him with hormones and amphetamines in an attempt to improve his sex drive.
Hitler Has Only Got One Ball: the bawdy 1939 song in full:
Hitler has only got one ball
The other is in the Albert Hall
His mother, the dirty b*****,
Cut it off when he was small
Hitler has only got one ball,
Göring has two but very small,
Himmler has something sim’lar,
But poor old Goebbels has no balls at all.
