"Lina Medina (born September 27, 1933) is the youngest confirmed mother in medical history, giving birth at the age of 5 years, 7 months and 21 days.
Born in Peru, Lina was brought to a hospital by her parents at the age of 5 years because of increasing abdominal size. She was originally thought to have had a tumor, but her doctors determined she was in her seventh month of pregnancy. 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 May 14, 1939, she gave birth to a boy by a caesarean section necessitated by her small pelvis. The surgery was performed by Dr. Lozada and Dr. Busalleu, with Dr. Colretta providing anaesthesia. Her case was reported in detail by Dr. Edmundo Escomel to La Presse Medicale, along with the additional details that her menarche had occurred at 8 months of age (or 2 1/2 according to a different article), and that she had had prominent breast development by the age of 4. By age 5 her figure displayed pelvic widening and advanced bone maturation."
