The age of viability refers to the period of time when the developing fetus is able to survive outside of its motherâs womb. Generally, the age of viability of a fetus is considered to be between 22 and 26 weeks after conception. Survival of a child born prior to the full gestational age (40 weeks) improves greatly during the third trimester. The survival rates at different times during the age of variability are as follows: 21 weeks or less: survival rate is 0%.
With the support of neonatal intensive care units, the limit of viability in the developed world has declined since 50 years ago, but has remained unchanged in the last 12 years. Currently the limit of viability is considered to be around 24 weeks although the incidence of major disabilities remains high at this point.
