Adolf Hitler had a tiny chap, according to historians Jonathan Mayo and Emma Craigie.
Writing in the book ‘Hitler’s Last Day: Minute by Minute,’ the researchers claim the Führer was cursed with a “micro-penis.”
The infamous 1939 nursery rhyme, in which the former leader of the Third Reich is mocked for allegedly having one testicle, may have masked a smaller truth.
The historians claim to have unearthed Nazi medical records that reveal Hitler had a rare condition called hypospadias.
“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,” they wrote.
Craigie and Mayo built on the work of German historian Peter Fleischmann, who last year claimed to have found medical data confirming the Austrian had an undescended ball.
Hitler’s private doctor, Theodor Morell, is believed to have given Hitler hormones and cocaine to boost his sex drive to the benefit of his wife Eva Braun.
