DNA research suggests Hitler likely had condition limiting sexual development
The findings feature in a new documentary, and were made possible by testing blood from the sofa on which Hitler shot himself

Adolf Hitler most likely suffered from the genetic condition Kallmann Syndrome that can manifest itself in undescended testicles and a micropenis, researchers and documentary makers said on Thursday, following DNA testing of the Nazi dictator’s blood.
The new research also quashed the suggestion that Hitler had Jewish ancestry.
Popular World War II songs often mocked Hitler’s anatomy, but lacked any scientific basis.
The findings by an international team of scientists and historians now appear to confirm long-standing suspicions around his sexual development.
“No one has ever really been able to explain why Hitler was so uncomfortable around women throughout his life, or why he probably never entered into intimate relations with women,” said Alex Kay of the University of Potsdam.
“But now we know that he had Kallmann Syndrome, this could be the answer we’ve been looking for.”
