She holds the record for being the youngest confirmed mother in medical history. Lina was born on September 27, 1933, in Ticrapo, Peru. At the age of five years and seven months, she gave birth to a baby boy named Gerardo on May 14, 1939. Lina's case was extremely rare and shocking. Her pregnancy was discovered when her parents took her to the hospital due to an abdominal swelling they thought was caused by a tumor. However, it was revealed that Lina was actually seven months pregnant. The father of Lina's child was never identified, and there were suspicions of sexual abuse within her family. Due to the young age and physical immaturity of her body, Lina had to undergo a cesarean section to deliver her baby safely.

Lina and her son Gerardo lived a relatively private life after the incident. Gerardo grew up believing that Lina was his sister until he was told the truth at the age of 10. Lina never publicly disclosed the identity of Gerardo's father. The case of Lina Medina raised ethical and medical questions at the time and continues to be studied by experts. It is still not fully understood why Lina reached puberty at such a young age and was able to conceive and carry a child. Lina's story serves as a reminder of the importance of education, healthcare, and child protection to prevent such cases from happening in the future.
