In 1939, Lina Medina of Peru became the youngest mother in history when she gave birth to a boy at just the age of five.
In 1933, Lina's mother noticed her growing stomach after she complained about being in pain. Doctors initially feared the large bump was a tumor but soon realized the five-year-old child was seven-months-pregnant.
It soon emerged that Lina had mature sexual organs and suffered from a condition called precocious puberty. Her mum reportedly noticed her daughter started having periods aged three and her breasts were nearly fully developed by the age of four.
Another medical report from Peru said the child started menstruating at just eight months old, which conflicts with the mother's claims. On May 14, 1939, she gave birth to a baby boy via cesarean as her young pelvis was deemed too small for a natural birth.
Her baby was born a healthy 6lbs and was named Gerardo in honor of the doctor who delivered him. It has never been revealed who raped Lina, Her father was arrested after the birth but was released due to lack of evidence.
