Uncovered medical records show Hitler suffered from a condition called hypospadias which left him with abnormally sized reproductive organs according to reports by the Telegraph.
This is the second genital dysfunction reported regarding the Nazi regime leader.
In their book entitled, "Hitler's Last Day: Minute by Minute," historians Jonathan Mayo and Emma Craigie discuss uncovered medical records which show that Hitler had a micropenis.
This report comes just month after a medical document showing that Adolf Hitler only had one testicle was reported in German media, suggesting there is some truth to a popular British song that says the dictator had "only got one ball."
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 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.Reuters contributed to this report.
