Roberto Esquivel Cabrera, from Saltillo, Mexico, gained worldwide attention on his appendage after claiming that it is 18.9 inches long - making it the largest in the world.
However, if a doctor is to be believed, the Mexican can just be making tall tales, with suggestions his member is only six inches long.
Radiologist Dr Jesus Pablo Gil Muro, who has examined Roberto, threw the world record claims into doubt when he said the man refused to take off all the bandages and would not let him see the skin.
Dr Muro said that when he went to him to do a CT scan, his first impression was that it was a unique and unusual case. Becoming suspicious, he conducted a CT scan and found that there is a very large foreskin which goes just before the knee.
"But the penis itself is about 16 to 18cm from the pubis,” he said, adding, “The rest of the tissue found there is just foreskin, blood vessels, and some inflammation of the skin.”
It then emerged that Roberto had revealed to his psychiatrist that he had began enlarging his penis since he was a teenager.
It is understood 54-year-old Roberto has been stretching it with weights since he was a teenager. The claims have sent quivers through the world record community, particularly after the man with the second largest penis in the world argued Roberto’s todger was not what it made out to be.
Jonah Falcon, 47, who claims to have a 13.5inch penis, says the fact that Roberto Esquivel Cabrera used weights means his claim is not real.
