Lina Medina, a girl who was only five years old has entered history books as the youngest ever to give birth.
But after running tests they found she was seven months pregnant and weeks later she gave birth to a healthy baby boy.
She was born in a small village in the Andes in Peru to a poor family in 1933.
At the age of five, her mother noticed her growing abdomen after she complained about having stomach pains
Just weeks later on May 14, 1939, she gave birth to a baby boy by a Caesaerean as her young pelvis was deemed to small for a natural birth.
Her baby was born a healthy 6lbs and the infant was named Gerardo in honour of the doctor who delivered him.
When Gerardo was born , the doctor discovered that despite being five years old, she had mature sexual organs and suffered from a a condition called precocious puberty.
It was believed her father had committed incest with his daughter and he was arrested.
Growing up, Gerardo always believed Lina was his sister but at the age of ten was told she was his mother.
Gerardo grew up healthy but died at the age of 40 in 1979 after suffering from a bone disease.
