At the age of five, most of us are occupied by toys and spaghetti shapes. But Lina Medina was just five years old when doctors realised she was seven months pregnant.
Weeks later, she gave birth to a healthy baby boy, who she named Gerado after the doctor who delivered him, according to The Sun.
Medina lived in Peru, and was born in 1933. Her parents noticed her stomach was growing, and she started getting stomach pains. It turned out Medina had mature sexual organs, and a condition called precocious puberty – where a child’s body changes into an adult’s.
It is believed her father committed incest with Medina, but there wasn’t enough evidence to prosecute.
Until the age of ten, Gerardo was told he was Medina’s sister. He died at the age of 40 from a bone disease.
Medina is now 85 years old, and had a second son later in life.
