(FILES) This file portrait dated 1938 shows German Nazi Chancellor Adolf Hitler (1889-1945). 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 November 13, 2025, following DNA testing of the Nazi dictator's blood. The new research also quashes the suggestion that Hitler had Jewish ancestry. (Photo by AFP) (Photo by -/AFP via Getty Images)
