The youngest mother in the world-5 years old

 Lina Medina 5 years old , ragged Indian woman from the foothills of the Andes looked tired in the hospital at Pisco(Peru) from the foothills of the Andes. Pointing to the frightened child, the Indian woman begged Surgeon Geraldo Lozada to exorcise the evil spirits which had taken possession of her. Certain that little Lina Medina had an abdominal tumor, Dr. Lozada examined her, and received the surprise of his life when he discovered she was eight months pregnant, making her the world's youngest mother ever.

Dr. Lozada took her to Lima, the capital of 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 the 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, 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.
Her son weighed 2.7 kg (6 lb) at birth and was named Gerardo after her doctor. Gerardo was raised and peoples thought Lina was his sister, but found out at the age of ten that she was his mother. He grew up healthy but passed away in 1979 at the age 40,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. Medina later married Raúl Jurado, who fathered her second son in 1972. They live in a poor district of Lima known as Chicago Chico ("Little Chicago"). She refused an interview with Reuters in 2002. This above photograph is of significant value because it proves Medina's pregnancy as well as the extent of her physiological development.Extreme degrees of precocious puberty in children under 5 are very uncommon but not unheard of.
