New German medical records, which have been unearthed 93 years after they were originally recorded, claim that Adolf Hitler had a micro-penis.Historians think that this embarrassing penis deformity of Hitler may be the reason behind his rage and lack of sex life during his 56 years, the Daily Star reported.Medical records following the Nazi Party leader's arrest in 1923 suggest that he suffered "right-side cryptorchidism," the medical name for an undescended testicle and that his genitalia may have been more deformed than first thought.New records show the fascist leader also had a related condition called Hypospadias, which can leave the sufferer with a "micro-penis."Hypospadias sufferers may be forced to urinate out of a small hole at the base, or shaft of the penis, rather than at the tip.Historians Jonathan Mayo and Emma Craigie said in the new book 'Hitler's Last Day: Minute by Minute' that the Nazi leader, who was well known to have a fear of people seeing him naked and never became a father, kept the dark secret close to him.They noted that Hitler himself is believed to have had two forms of genital abnormality, an undescended testicle and a rare condition called penile Hypospadius, in which the urethra opens on the underside of the penis.Personal doctor Theodor Morell, who prescribed Hitler amphetamines, hormones and cocaine on occasion, to hike the leader's libido, is also said to have recorded the Fuhrer's penis deformity.Nazi architect Albert Speer, who was responsible for designing colossal buildings for Hitler, said the leader's absent sex drive was very noticeable following the war, adding that in the case of Eva Braun in particular, aside from occasional passionate episodes, there was no sexual activity at all for long periods of time.Rumour has it that during the Battle of the Somme in the First World War, a flying piece of hot shrapnel sliced into Fuhrer's testicles.
