In 1939, a man walked into a hospital in Pisco, Peru, carrying his five-year-old daughter. He wasn't there for a check-up. He was terrified. He told the doctors his little girl, Lina, had a massive tumor growing in her belly. Local shamans had tried to "cure" her, but the swelling just kept getting bigger.
The doctor, Gerardo Lozada, took one look at her and felt his heart drop. It wasn't a tumor.
After a quick examination, the medical team realized the unthinkable. This child—who was still playing with dolls and hadn't even lost all her baby teeth—was seven months pregnant.
Lina Medina is the answer to the question of who is the youngest mother in world history. She gave birth at the age of 5 years, 7 months, and 21 days. It sounds like an urban legend or a dark fairy tale, but it’s one of the most well-documented cases in medical history.
The Birth That Shocked the World
On May 14, 1939, which happened to be Mother’s Day, Lina underwent a cesarean section. Her pelvis was simply too small for a natural birth.
The surgery was performed by Dr. Lozada and Dr. Alejandro Busalleu. They brought a 6-pound baby boy into the world. He was healthy. He was normal. They named him Gerardo, after the doctor who first believed the impossible truth.
Imagine the scene.

You’ve got dozens of skeptical doctors from all over Peru and eventually the world, peering into an operating room. They expected to find a mass or some bizarre medical anomaly. Instead, they found a fully formed fetus.
How is This Biologically Possible?
Honestly, the biology is the only part that makes "sense," even if it’s horrifying.
Lina suffered from a rare condition called precocious puberty. Basically, her body’s internal clock hit fast-forward. Most girls start puberty between 8 and 13. Lina? Medical records from Dr. Edmundo Escomel, a prominent researcher at the time, noted that she started menstruating at eight months old. By the time she was four, she had developed breasts and widened hips.
Her bone age was that of an adult, even though she was just a kindergartner.
It’s a glitch in the human endocrine system. Usually, the pituitary gland waits for a signal to start releasing hormones. In Lina’s case, the "brake" on that system failed.
The Mystery of the Father
This is where the story gets even darker.

Who did this? We still don't know.
The Peruvian authorities arrested Lina’s father on suspicion of incest and sexual abuse. They eventually had to let him go because there was zero physical evidence and Lina herself couldn't—or wouldn't—explain what happened. A brother was also briefly suspected.
In the remote Andean village where they lived, there were whispers about "evil spirits" or the "snake Tiracha," a local myth used to explain mysterious pregnancies. But the reality was likely much more grounded in human cruelty.
Lina remained silent about the father her entire life. She lived to be an old woman, eventually marrying and having another son in the 1970s, but she never did a "tell-all" interview. She stayed out of the spotlight as much as a "medical miracle" could.
What Happened to the Baby?
Gerardo grew up in the Medina household. For the first ten years of his life, he thought Lina was his sister.
Can you imagine that moment of realization?

He eventually found out the truth from schoolmates. Despite the trauma of his origins, Gerardo lived a relatively normal life. He was healthy and reached adulthood, though he sadly passed away in 1979 at age 40 due to a bone marrow disease. There's no evidence his early death was related to the circumstances of his birth.
Why This Case Still Matters Today
We look at this now and it feels like a relic of a different era, but it serves as a massive case study for modern pediatric endocrinology.
Today, if a child shows signs of precocious puberty—like hair growth or breast development before age eight—doctors can intervene. We have synthetic hormones (GnRH agonists) that can effectively "pause" puberty. This allows the child to grow physically and mentally at a normal pace.
Back in 1939, they had no such tools. They just had a confused little girl and a medical mystery.
Key Takeaways and Next Steps
- Medical Awareness: Precocious puberty is real. If you notice signs of early development in young children, consult a pediatric endocrinologist immediately.
- Documentation: The Medina case is supported by X-rays, biopsies, and witness accounts from the Peruvian Academy of Medicine. It's not a "hoax."
- Protection: This story is a stark reminder of the vulnerability of children. Legal and social systems have evolved significantly since 1939 to protect minors, but the medical reality of early fertility remains a serious concern in cases of abuse.
