A baby born between 20 and 26 weeks is a considered to be periviable, or born during the window when a fetus has a chance of surviving outside the womb. These babies are called “micro-preemies.” A baby born before 24 weeks has less than a 50 percent chance at survival, say the experts at University of Utah Health.
Can micro preemies survive?
Survival can range from 10% in underdeveloped countries to 90% in developed countries. 3 However, many more micro-preemies are surviving today than ever before due to advances in medical knowledge and technology that can care for them.
How many weeks until a baby can survive out of the womb?
Doctors now consider 22 weeks the earliest gestational age when a baby is “viable,” or able to survive outside the womb. But this is still extremely premature, and a baby born at this age will need a great deal of medical attention. Even if he survives, the risk of permanent disability is very high.
Can a baby be viable at 20 weeks?
New research confirmed that 22-week fetuses, measured from the first day of the pregnant woman’s last menstrual cycle, can survive. Babies born before that age did not survive. So, Lawrence is correct that 20-week fetuses, measured from the first day of the pregnant woman’s last menstrual cycle, are not viable.

How long do micro preemies live?
A micro preemie is a baby who is born weighing less than 1 pound, 12 ounces (800 grams), or before 26 weeks gestation….Survival Rate for Micro Preemies.
