Newly released genetic research indicates that Adolf Hitler may have had a rare condition that affects sexual development.
The data was presented in a documentary titled Hitler’s DNA: Blueprint of a Dictator that aired on the U.K.’s Channel 4 last week.
According to researchers, the findings indicate that Hitler had Kallmann syndrome, which is a developmental disorder that disrupts the onset of puberty and can result in a micropenis.
- New genetic research suggests Adolf Hitler had Kallmann syndrome, impacting sexual development and possibly leading to a micropenis.
- DNA from bloodstained fabric linked to Hitler was confirmed by matching his Y chromosome with a living relative.
- Hitler's reduced testosterone from Kallmann syndrome may explain his political obsession and lack of private life or relationships.

The Cleveland Clinic says the disorder happens when certain genes change during fetal development, with some people inheriting the gene changes.
It can result in reduced testosterone levels, something the program’s contributors say could help explain aspects of Hitler’s private life and behavior.
There have long been rumors about Hitler’s genitalia but there was no evidence to back it up.
“This would help to explain Hitler’s highly unusual and almost complete devotion to politics in his life to the exclusion of any kind of private life,” Alex J. Kay, a historian at the University of Potsdam, said in the film, as reported by The Times.
“Other senior Nazis had wives, children, even extramarital affairs. Hitler is the one person among the whole Nazi leadership who doesn’t.”

The findings are based on DNA taken from a bloodstained piece of fabric believed to have come from Hitler’s bunker in Berlin, where he died in 1945.
According to the documentary, the sample’s Y chromosome was compared with that of a living male relative, allowing the research team to confirm it belonged to Hitler.
The program reports that Kallmann syndrome could also align with longstanding descriptions in medical and historical records referring to an undescended testicle.
Researchers featured in the film added that, based on the genetic markers present, Hitler had a one in 10 chance of having a micropenis.
Professor Turi King, the geneticist who led the analysis, said the findings highlight an irony given Hitler’s fixation on the idea of genetic purity.

“If he was to look at his own genetic results, he would have almost certainly have sent himself to the gas chambers,” she said in the documentary.
She added that interpretations of the data must be cautious. “The biggest thing I want to have come out of this is the complexity of genetics and the complexity of conditions.
“People see DNA as the silver bullet that will answer everything. People often view DNA as deterministic, which it is not. DNA is always just a part of the puzzle about who somebody is … You cannot see evil in a genome.”
Researchers also looked at other parts of the DNA and say the results suggested a higher genetic risk for conditions such as autism, schizophrenia, and bipolar disorder.
However, scientists stressed that such scores do not amount to diagnoses and cannot be used to retroactively assess a historical figure’s mental health.
The documentary also addresses long-circulated rumors about Hitler’s ancestry.
Based on the Y-chromosome data, the team says there is no genetic support for claims that he was Jewish, with the results instead pointing to central European ancestry consistent with his known family background.
Historians and scientists interviewed for the film emphasized that the genetic findings should not be used to draw direct links between biology and Hitler’s political actions or the crimes committed under his leadership.
The documentary notes that while the results may shed light on aspects of his personal life, they cannot explain the ideology he advanced or the decisions he made.
