Lina Medina is the world's youngest confirmed mother in medical history.
Born in Peru on 27 September 1933, Lina was brought to a hospital by her parents at the age of 5 because of an increasing abdominal size. Originally thought to have tumor, her doctors determined that she was in fact seven months pregnant.
Dr. Gerardo Lozada took her to Lima, Peru, prior to the surgery to have other specialists confirm that Lina was in fact pregnant. A month and a half later, on 14 May 1939, she gave birth to a boy by caesarean section.
Her son weighed 2.7 kg at birth and was named Gerardo after her doctor. Gerardo was raised believing that Lina was his sister, but found out at the age of ten that she was his mother. He grew up healthy but died in 1979 at the age of 40 of a disease of the bone marrow.
There was never evidence that Lina Medina's pregnancy occurred in any but the usual way, but she never revealed the father of the child, nor the circumstances of her impregnation. Dr. Escomel suggested she might not actually know herself by writing that Lina "couldn't give precise responses". Lina's father was arrested on suspicion of rape and incest, but was later released due to lack of evidence.
