Youngest Recorded Human Pregnancy: Lina Medina at Age 5

Earliest Confirmed Pregnancy

The youngest documented case is Lina Medina of Peru, who gave birth via cesarean section in 1939 at 5 years, 7 months, 21 days. She had precocious puberty (menarche at ~8 months). The baby, Gerardo, was healthy.

Context

• Pregnancy requires ovulation, which normally begins at puberty (average 12–13).
• Precocious puberty is rare; causes include CNS lesions, hormonal tumors, idiopathic.
• Such cases are medical anomalies, not normative.

No defined “minimum age” exists biologically, but functional reproductive capacity requires completed puberty.
