fetal viability
The ability of a fetus to survive outside the womb.

Historically, a fetus was considered to be capable of living at the end of gestational week twenty when the mother felt fetal movement (quickening) and the fetal heart tones could be auscultated with a fetoscope.

In reality, even with prompt and intensive neonatal support, a preterm fetus of less than twenty-five weeks' gestation has little chance of surviving outside the womb.
