Can a baby live outside the womb after the 20 week of pregnancy?

The age of viability is 24-26 weeks gestation, although a baby born that early will have some complications. A baby born at 20weeks gestation cannot survive outside of the womb; therefore, the further along the pregnancy, the greater the chances of survival for the fetus. Babies born very premature have immature lungs, brain functioning capabilities, skin is very fragile; therefore these babies are unable to regulate their body temperature. In other words the baby is most likely not going to survive.
