Lina Medina (born September 27, 1933, in Ticrapo, Huancavelica Region, Peru) is the youngest confirmed mother in medical history, giving birth at the age of five years, seven months and 21 days.
Born in Ticrapo, Peru, Medina was brought to a hospital by her parents at the age of five years due to 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 Medina was 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. Colareta providing anaesthesia. Her case was reported in detail by Dr. Edmundo Escomel in the medical journal La Presse Médicale, including the additional details that her menarche had occurred at eight months of age (or 2½ according to a different article) and that she had prominent breast development by the age of four. By age five, her figure displayed pelvic widening and advanced bone maturation.
