Age of Viability


5 months, 1 week

From The Biology of Prenatal Development.Buy Now

Script: Dentro de 21 a 22 semanas após a fertilização, os pulmões ganham certa habilidade de respirar ar. Esta é considerada a idade da viabilidade, porque a sobrevivência fora do útero torna-se possível para alguns fetos.

All ages referenced to fertilization, not last menstrual period. One month = 4 weeks.
