A medical document shows Adolf Hitler had only one testicle, German media have reported, suggesting there is some truth to the popular ditty that says the dictator had "only got one ball".
There has long been speculation that Hitler was missing one testicle, with rumours circulating that he lost the other one during the Battle of the Somme in the First World War.
But a medical record from the time when Hitler was put in prison after the failed Munich beer hall putsch in 1923 shows he suffered from "right-side cryptorchidism" - a condition where a testicle fails to descend into the scrotum - media reports on Saturday said.
The doctor's notes were thought to have been missing for years but reappeared at an auction in 2010, at which point they were seized by authorities.
"The experienced medical officer immediately recognised the condition!" top-selling newspaper Bild quoted historian Peter Fleischmann, who has studied the record, as saying.
