Adolf Hitler most likely suffered from a rare genetic condition called Kallmann Syndrome, researchers and documentary makers said Thursday, following DNA testing of the Nazi dictator's blood. According to the Cleveland Clinic, the syndrome can "disrupt the process that drives puberty" and manifest in symptoms that include undescended testicles and a micropenis.

Axar.az informs, citing CBS news, the research also quashes the suggestion that Hitler had Jewish ancestry, the researcher say.

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 longstanding 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."

The research findings are featured in a new documentary, "Hitler's DNA: Blueprint of a Dictator," due to be broadcast on Saturday.

The testing was made possible after researchers obtained a sample of Hitler's blood from a piece of material taken from the sofa on which he shot himself.
