Nazi dictator Adolf Hitler legendarily had only one testicle. But he also had a "tiny deformed penis," according to researchers who claim to have uncovered the truth in medical records.
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.
